''' Because Bitcoin's difficulty re-calculation is about every 2016 blocks, the chain with the lower hash rate will die off almost immediately. Miners on this smaller chain will be bleeding money by having to do more work for less pay. Most mining pools will go out of business very quickly. There are more articulate and tech savvy people than me that can explain this better than me, I recommend you visit BTC and post this question if you are looking for a more detailed answer.

Hello. 👋🏻 Today we will tell you about ACIS-mining and its 3 best algorithms. 📌 With the advent of ASICs for mining, it became possible to mine Bitcoin in much larger quantities than using video cards. ASIC is an integrated circuit specialized to solve a specific problem, in our case, only for bitcoin mining. These schemes are many times more profitable than video cards, because with more power (hash calculation speed) they consume much less energy. This served as a good reason to create a cryptocurrency mining business. 📌 In bitcoin and other blockchain systems, the complexity of mining depends on how quickly the miners find the block. Compared with the GPU and CPU, specialized #ASIC miners solve #PoW puzzles better and are therefore able to quickly find new blocks. 📌 Since PoW is still the preferred mining consensus mechanism, we propose to take a multiple algorithm approach. Instead of trying to use algorithms which are ASIC resistant, we propose to use algorithms which have had ASIC miners for quite some time. These are: #SHA256, #Scrypt, and #X11. 🔹 The SHA-256 algorithm has a number of advantages over other information protection technologies. Over the years of use in the cryptocurrency industry, he has shown his resistance to various hacking attempts. 🔹 Scrypt is a cryptocurrency mining algorithm that was previously interesting to many single miners in view of its resistance to the so-called “hardware attack”. The speed of creating blocks in a Scrypt-based blockchain is about 30 seconds. The hashrate, like Ethash, is measured in Megahash per second. Scrypt, first of all, became popular due to its use in Litecoin #cryptocurrency. 🔹 X11 is an encryption algorithm in which eleven are used instead of one function. This means that this technology can provide a high degree of security, because in order to harm the system, an attacker will have to crack all 11 functions, which is very unlikely, because the changes made will be visible after breaking the first function, and developers will have a lot of time to protect the system before the hacker reaches the eleventh function. Since these miners are already in wide use, the distribution of mining should be fair and even. Furthermore, the use of three different algorithms results in a far less chance of any single person gaining a majority hash rate share. Lastly, we use the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining.

Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it. Filecoin announced, that there will be more delays before its main network is officially launched. Filecoin developers postponed the release date of their main network to late July to late August 2020. As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process. Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market. Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors. The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020. They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit. The Filecoin team noted the following: “We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks. Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet. The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020. The updates to the project can be found on the Filecoin Road Map. Filecoin developers stated: “This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage. Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain. In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards. Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21. Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price. Mining in Filecoin In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency. Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data. Filecoin will contain several types of miners: Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out. Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power. Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network. The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into. In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.
The current system specifications recommended for running the miner are:
NVIDIA-manufactured GPU (to be expanded).
SSD drive designated as large buffer (512GB +).
Large amount of RAM for data replication account (128GB +)
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars. Proceed to mining Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract. Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually. After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started. Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page. At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention. Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt. Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network. Duration of operation, cutting and penalties “Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network. In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error. Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily. An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection. The sector will pay an error fee after the penalty of the sector once the error is discovered. Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network. Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function. Filecoin miners Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.” With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices. Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless. Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers. Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network. However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners. These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB). Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development. “Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital. “Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said. Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT. In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive. To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day. As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force. The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million. This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs. After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020. The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process? Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance. In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners: The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue. It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown. It seeks to promote mining using Filecoin Discover Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day. Ian Darrow, Head of Operations at Filecoin, commented on the announcement: “Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”. Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more. Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds. In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations. The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested. “The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”. IPFS and Filecoin Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure. IPFS It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live. The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides. Using IPFS In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data. Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service. Using Filecoin The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone. Filecoin, powered by IPFS It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS. Some advantages of sharing Filecoin with IPFS:
Filecoin and IPFS CIDs share hash specifications.
Use libp2p by Filecoin nodes to create secure connections with each other.
Messaging between nodes and cluster propagation is facilitated in Filecoin by libp2p pubsub.
IPLD use for blockchain data structures.
Use Graphsync to transfer data between nodes.
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol. Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated. PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage. In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected. Resources :
Hello, community! 👋🏻 In this post, we will tell you about Proof-of-Work and Proof-of-Stake algorithms and why PYRK uses PoW. ⛏ Proof of work allows the blockchain to remain “clean”, allows the entire community to compete to verify the validity of transactions, and makes attacks on the system very costly. But is this cost of attack justified? Aste argues that it should be sufficient to make the double-spend attack too costly. ⛏ A double spend attack can occur in a situation where an attacker tries to send the same bitcoin to two different users. In such a case, the attacker would try to spend as many bitcoins as possible twice. This number is limited by the number of transactions that can fit in a block, which in value terms is currently about $ 2 million. ⛏ A transaction involving more than the total cost of transactions in the block will attract attention from the network. This puts a real limit on the size of a double spend of about $ 2 million. And although the duplication of transactions can be repeated several times sequentially or in parallel, we will neglect it in this calculation. 🏆 PYRK Proof-of-Work triple algorithm 🔹 PYRK takes a multiple algorithm approach. We propose to use algorithms which have had ASIC miners for quite some time. These are: SHA256, Scrypt, and X11. 🔹 Since these algorithms are already in wide use, the distribution of mining should be fair and even. 🔹 There’s a far less chance of any single person gaining a majority hash rate share when using three different algorithms simultaneously. 🔹 Also, we use the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining. 💡 The idea of multi-algorithm originated in Digibyte. Splitting the mining into three different algorithms effectively splits the amount of work performed by each algorithm to 33% of the total network hashrate. The triple algorithm approach helps to further protect the network from bad actors while also providing the preferred Proof-of-Work mechanism.

Bitcoin at $ 288,000? BTC price shows bullish signal like 2016
Bitcoin's price development has been relatively stable in recent weeks. The cryptocurrency has been trading in the $ 9,200 range since early June, which is the price at the time of publication. However, Bitcoin is currently showing signals that could indicate an upcoming bull market. According to a report by the Kraken Stock Exchange, Bitcoin is only a 10% jump away from entering a massive upward trend. As Kraken describes, to enter a bull market, Bitcoin must break the key resistance at $ 10,500, as shown below. https://preview.redd.it/0d4bm64zsla51.png?width=1276&format=png&auto=webp&s=b3a670c135792f34af6714fc8ab9d48cef7dc77e With that in mind, the report says Bitcoin could soon break resistance or take the risk of testing support at $ 6,000 to $ 7,000. This would end a period that some analysts have described as very stable. In fact, this is similar to the price development in 2016 and 2017, when Bitcoin initially tended to move sideways for a very long time and finally reached its all-time high of USD 20,000 in late 2017. According to analyst Moon Capital, the Bitcoin hash ribbons have crossed, revealing a massive buy signal that has historically pushed Bitcoin's price up. The signal was also there before the 2017 Bull Run. Therefore, the analyst predicts that BTC will rise to $ 288,000. The "hash ribbons" indicator is based on the hash rate of the Bitcoin network. It is calculated by comparing the short-term moving average and the long-term moving average of the Bitcoin hash rate. As soon as these two cross, a bullish indicator is generated. A breakdown is considered bearish. Capriole's digital asset manager, Charles Edwards, also noted the formation of this indicator. However, Edwards recommended waiting until midnight today (July 12th UTC) for the crossing of the hash ribbons to be confirmed. He also said the BTC price for confirmation should close above $ 9,230.
Bitcoin fundamentals support upcoming uptrend
On the other hand, Bitcoin's fundamentals seem to support a bull market. Bitcoin's hash rate has increased significantly since the difficulty adjustment in June. According to blockchain.com, the hash rate of Bitcoin reached a new high of 125.99 terra hashes per second (TH / s) on July 7. In this context, analyst and inventor of Bitcoin's stock-to-flow model, Plan B, said Bitcoin has weathered the worst of the past few months. In addition, he stressed that the cryptocurrency will soon peak at its hash rate, confirming the good health of the Bitcoin network.

That is, the proof of work means that it takes a certain amount of computer time to confirm the work. -Principle: Figure 7 PoW work proof principle 📷 https://preview.redd.it/xupacdfc4db51.png?width=554&format=png&auto=webp&s=3b6994641f5890804d93dfed9ecfd29308c8e0cc The PoW represented by Bitcoin uses the SHA-256 algorithm function, which is a 256-bit hash algorithm in the password hash function family: Proof of work output = SHA256 (SHA256 (block header)); if (output of proof of work if (output of proof of work >= target value), change the random number, recursive i logic, continue to compare with the target value. New difficulty value = old difficulty value* (time spent by last 2016 blocks /20160 minutes) Target value = maximum target value / difficulty value The maximum target value is a fixed number. If the last 2016 blocks took less than 20160 minutes, then this coefficient will be small, and the target value will be adjusted bigger, if not, the target value will be adjusted smaller. Bitcoin mining difficulty and block generation speed will be inversely proportional to the appropriate adjustment of block generation speed. -Representative applications: BTC, etc. 》POS -Concept: Proof of stake. That is, a mechanism for reaching consensus based on the holding currency. The longer the currency is held, the greater the probability of getting a reward. -Principle: PoS implementation algorithm formula: hash(block_header) = Coin age calculation formula: coinage = number of coins * remaining usage time of coins Among them, coinage means coin age, which means that the older the coin age, the easier it is to get answers. The calculation of the coin age is obtained by multiplying the coins owned by the miner by the remaining usage time of each coin, which also means that the more coins you have, the easier it is to get answers. In this way, pos solves the problem of wasting resources in pow, and miners cannot own 51% coins from the entire network, so it also solves the problem of 51% attacks. -Representative applications: ETH, etc. 》DPoS -Concept: Delegated proof of stake. That is, currency holding investors select super nodes by voting to operate the entire network , similar to the people's congress system. -Principle: The DPOS algorithm is divided into two parts. Elect a group of block producers and schedule production. Election: Only permanent nodes with the right to be elected can be elected, and ultimately only the top N witnesses can be elected. These N individuals must obtain more than 50% of the votes to be successfully elected. In addition, this list will be re-elected at regular intervals. Scheduled production: Under normal circumstances, block producers take turns to generate a block every 3 seconds. Assuming that no producer misses his order, then the chain they produce is bound to be the longest chain. When a witness produces a block, a block needs to be generated every 2s. If the specified time is exceeded, the current witness will lose the right to produce and the right will be transferred to the next witness. Then the witness is not only unpaid, but also may lose his identity. -Representative applications: EOS, etc. 》DPoW -Concept: Delayed proof of work. A new-generation consensus mechanism based on PoB and DPoS. Miners use their own computing power, through the hash algorithm, and finally prove their work, get the corresponding wood, wood is not tradable. After the wood has accumulated to a certain amount, you can go to the burning site to burn the wood. This can achieve a balance between computing power and mining rights. -Principle: In the DPoW-based blockchain, miners are no longer rewarded tokens, but "wood" that can be burned, burning wood. Miners use their own computing power, through the hash algorithm, and finally prove their work, get the corresponding wood, wood is not tradable. After the wood has accumulated to a certain amount, you can go to the burning site to burn the wood. Through a set of algorithms, people who burn more wood or BP or a group of BP can obtain the right to generate blocks in the next event segment, and get rewards (tokens) after successful block generation. Since more than one person may burn wood in a time period, the probability of producing blocks in the next time period is determined by the amount of wood burned by oneself. The more it is burned, the higher the probability of obtaining block rights in the next period. Two node types: notary node and normal node. The 64 notary nodes are elected by the stakeholders of the dPoW blockchain, and the notarized confirmed blocks can be added from the dPoW blockchain to the attached PoW blockchain. Once a block is added, the hash value of the block will be added to the Bitcoin transaction signed by 33 notary nodes, and a hash will be created to the dPow block record of the Bitcoin blockchain. This record has been notarized by most notary nodes in the network. In order to avoid wars on mining between notary nodes, and thereby reduce the efficiency of the network, Komodo designed a mining method that uses a polling mechanism. This method has two operating modes. In the "No Notary" (No Notary) mode, all network nodes can participate in mining, which is similar to the traditional PoW consensus mechanism. In the "Notaries Active" mode, network notaries use a significantly reduced network difficulty rate to mine. In the "Notary Public Activation" mode, each notary public is allowed to mine a block with its current difficulty, while other notary public nodes must use 10 times the difficulty of mining, and all normal nodes use 100 times the difficulty of the notary public node.

That is, the complexity of the algorithm is reduced from exponential to polynomial level, making the Byzantine fault-tolerant algorithm feasible in practical system applications. -Principle: Figure 9 PBFT algorithm principle 📷 https://preview.redd.it/8as7rgre4db51.png?width=567&format=png&auto=webp&s=372be730af428f991375146efedd5315926af1ca First, the client sends a request to the master node to call the service operation, and then the master node broadcasts other copies of the request. All copies execute the request and send the result back to the client. The client needs to wait for f+1 different replica nodes to return the same result as the final result of the entire operation. Two qualifications: 1. All nodes must be deterministic. That is to say, the results of the operation must be the same under the same conditions and parameters. 2. All nodes must start from the same status. Under these two limited qualifications, even if there are failed replica nodes, the PBFT algorithm agrees on the total order of execution of all non-failed replica nodes, thereby ensuring security. -Representative applications: Tendermint Consensus, etc. Next Lecture: Chapter 3 Common Consensus Mechanisms (Part 2) + Chapter 4 Consensus Mechanism Selection and Status Summary CelesOS As the first DPOW financial blockchain operating system, CelesOS adopts consensus mechanism 3.0 to break through the "impossible triangle", which can provide high TPS while also allowing for decentralization.

Got this weird DM on reddit idk what this guy is up to have any of you ever heard of this https://tradeoptiongains.com Site? u/mikerobin25 Mikerobin2501:52 AM Hello there IDEKMyUsername09:34 AM Howdy Mikerobin2509:47 AM How's it going? IDEKMyUsername12:13 PM Not bad. What's up Mikerobin2512:36 PM I'm doing quite alright, How about you? IDEKMyUsername12:53 PM Not bad Mikerobin2501:39 PM Well, I don't mean to intrude but are you familiar with the term "cryptocurrency", Bitcoin to be precise? IDEKMyUsername03:10 PM Yes Aye Mikerobin2503:25 PM Well, I'm at the moment engaging in an outreach aimed at expanding the clientele of my platform and enlightening the populace on the monetary potential of bitcoin trading and mining. Would you be interested in this? IDEKMyUsername03:26 PM Uh yeah sure I can look into it. What does it include? Mikerobin2503:28 PM Are you familiar with the term "Bitcoin trading"? IDEKMyUsername03:29 PM Yeah somewhat Like selling and buying it? Mikerobin2503:33 PM Well, Bitcoin trading is the process of making profits by buying Bitcoin at a low cost and selling it when the price goes up, This method is referred to as Dollar Cost Averaging(DCA). The Bitcoin trade is volatile, and price move by a significant margin. This activity is done on trading platforms. Are you following? IDEKMyUsername04:07 PM Yep gotcha so far Sorry had to pickup a call Mikerobin2506:51 PM No problem mate. Every platform has an investment procedure and ROI method. Unlike other platforms that engage in day trading (profiting from the volatility of bitcoin which is inefficient), My platform is registered with S9 ant miners that mine the bitcoin you invest to increase exponentially and that’s how you earn profits. Have you heard of the term "Bitcoin mining"? IDEKMyUsername06:52 PM Yes I have Mikerobin2506:57 PM Good. For clarification, Bitcoin mining primarily involves generating and earning off the confirmation of blocks of transaction on the network such as the Blockchain network. This is made possible with the use of special and sophisticated devices called the Bit main devices, Such as the AntMiner S9 and ASIC hardware. These devices are extremely expensive to maintain and require a lot of electricity generation and technical expertise which makes it rarely an option for private individuals who are interested in going into Bitcoin mining. But my platform has been able to provide for this disability. Are you following? IDEKMyUsername06:57 PM I feel ya Yes Mikerobin2507:01 PM Moving on, My platform operates a full S9 Antminer farm. The Antminer s9 has a hash rate of 12.93TH/s which is -+ 7%, Which could generate a ROI of 0.5 BTC within an investment period depending on the investment capital. Note: ROI stands for return of investment while hash rates a measure of how many times the network can attempt to complete this puzzle every second. This means that hash rate is a good indicator of the Bitcoin network's health. Do i still have your attention? IDEKMyUsername07:02 PM Yes Mikerobin2507:05 PM Finally, All investments are made and monitored by the client (you) on the platform's website as you earn profits daily and you can contact me a "Broker" on the platform whenever you need assistance or more information. https://tradeoptiongains.com IDEKMyUsername07:05 PM Hm U have a history of wise investments? I mean don't really know you so not like your a "professional" of any means Mikerobin2507:06 PM Certainly We've been running for a span of 4 years now with optimum services provided IDEKMyUsername07:38 PM oh wow gimmie some more deets? how much money would I expect if i put a quick g bar in? IDEKMyUsername07:53 PM hm? Mikerobin2507:54 PM An investment of $1000 amounts up to the standard ROI stated above which is 50% of 1 bitcoin. Apologies for the late reply, Was attending to a client of mine. IDEKMyUsername07:55 PM so invest of about $1000 would give ruffly 5? nah ur good fam like how I go about that tho u know cause isn't bitcoin like kind of high right now? Mikerobin2507:57 PM Yeah though it would have been more profitable if you had started earlier when it was cheaper but you should be expecting more returns due to the halving coming up. https://www.bitcoinblockhalf.com/ IDEKMyUsername07:58 PM how high you think its going to get? Mikerobin2507:59 PM Its a highly speculative asset but from my experience and following it's previous halving events, Probably 15-18k. IDEKMyUsername08:01 PM oh jeez thats like as big as the big boom right? how you know its gonna do that? and what if it doesn't lol? do I just l;ose it all Mikerobin2508:05 PM Exactly. If it doesn't, It would remain at its breaking point of 9k or peak point of 10k but i highly doubt it doesn't pump(rise) based on past halving events. You can simply get started by creating your personal account on the platform by which you can start by purchasing bitcoin and you can do this by clicking on the "Register" icon to get started. IDEKMyUsername08:05 PM hmmm idk Kinda need some more security u know what I mean? Mikerobin2508:08 PM I understand. Loses are only made when you sell off, You money remains intact whether it rises or falls as long as you don't sell but your ROI is fully attained on your account on the platform. IDEKMyUsername08:09 PM o Mikerobin2508:10 PM Indeed Mikerobin2508:20 PM Any more questions? IDEKMyUsername08:20 PM uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh no Mikerobin2508:22 PM Okay then, I'm available here if you're interested and need my assistance Enjoy the rest of your day. IDEKMyUsername08:25 PM o ok Yesterday Mikerobin2501:48 PM https://www.fxstreet.com/cryptocurrencies/news/breaking-bitcoin-price-takes-down-9-000-as-10-000-beckons-202004300334 https://www.independent.co.uk/life-style/gadgets-and-tech/news/bitcoin-price-gold-oil-2020-best-performing-assets-a9492641.html IDEKMyUsername01:51 PM O I bought it Mikerobin2501:51 PM Pardon? IDEKMyUsername01:52 PM I bought one Mikerobin2501:52 PM On what platform? IDEKMyUsername01:54 PM I'm idk the one u sent me Um* Mikerobin2501:55 PM Really? When did you do this and why wasn't i informed? Today IDEKMyUsername10:19 AM Oh like last last night I thought it was expected U sent me the link and everything ;( Mikerobin2510:22 AM You would have informed me so i can enlighten you more on the procedure. Are you aware that it's a mining platform and you earn profits as an investor? IDEKMyUsername10:23 AM Yah so what would profit be ya reckon? For let's say $1000 over liek a year Mikerobin2510:24 AM What name did you use in registering the account? IDEKMyUsername10:24 AM Uh I'd have to look it up But how much profit did u say it would be about? Mikerobin2510:27 AM 0.5 BTC a month depending on your investment capital that is, I would need the name of your account to register it under my personal database so i can provide you with information and assistance when needed. IDEKMyUsername10:28 AM O damn that's some big bucks right there .5 btc like what 4g? 4 times 11 that's $44,000 a month Mikerobin2510:30 AM How much did you invest and what is the name of your account? Your profit is calculated in respect of your investment capital IDEKMyUsername10:31 AM Like 11grand Mikerobin2510:31 AM And the name? IDEKMyUsername10:31 AM Mmmm How do I find it? Is there a way on the site Mikerobin2510:31 AM What name did you use in creating the account? Didn't you register?

But suddenly your joy will turn to ashes in your mouth. and you'll know the debt is paid IDEKMyUsername08:01 PM Br You still my 11 grand Stole What's your name Tell me Or I'll find you
The One Thing EVERYONE Must Know About the Dev Funding Plan: IT'S COMPLETELY FREE.
sigh I get so tired of having to stop working to put out a post explaining issues. If anyone else wants to join in I could use help. (actually I've seen Jonald F. do this before too, so thanks JF!) Things are bad when even developers don't understand what's going on. So I'll try to clearly explain an important point on the Dev Funding Plan (DFP from now on) for the community: it's completely free. Yet we still get panicked posts saying Please Save Us from the TAX!!! Somebody Help! You may be for or against the DFP, but either way please at least understand what you're forming an opinion on. Let's start from the beginning. We know Bitcoin works on blocks and block coin rewards. The block reward, which started at 50 coins per block, and cuts in half approximately every 4 years, serves two purposes: it's a fair way to bring coins into circulation, but more importantly it provides security for the network. For simplicity, please think of "security" as being measured in power bars. When the network first started, with just Satoshi and Hal Finney, there was 1 power bar. This power bar was made up of the electricity their combined computer hardware used to find blocks. They were the first miners. Bitcoin uses a difficulty level to adjust how hard or easy it is to find blocks. This level is important for a key reason: we want the inflation rate of coins (how fast they come into circulation) to stay about the same, regardless how many miners (computing power) suddenly comes online. If the difficulty is set at super easy, but suddenly a super computer comes online that computer can gobble up thousands of coins in minutes if not seconds, creating massive rapid inflation. So the first thing to understand is that due to the Difficulty Level Adjustment the rate of coins coming into circulation will always stay about the same, regardless how many miners join or leave the network. Getting back to power bars. So the point of Bitcoin is there is no center, no fixed authority. The problem is we still need a decision made about which chain is valid. This is where proof-of-work comes in. Satoshi's fairly brilliant solution to a consensus decision, with no leader, was to simply look for the longest chain (technically the chain with most hashing work). The reasoning was: as there are far more ordinary people than there are governments and dictators a Bitcoin supported by the all the world's people should always be able to muster more hashrate than even rich governments. So Bitcoin began and people saw the brilliance: even with a weak power bar level of 1 (a couple computers), Bitcoin was safe from 51% attacks and attacking govs competing for control of the chain because a super low hashrate meant Bitcoin wasn't popular and govs wouldn't bother paying attention. By the time Bitcoin was big enough for govs to worry about attacking it should also have so many participants the power bar level would be far higher, providing strong defense. Let's say the ideal power bar level is 50,000. At this level no government on earth has enough resources to beat the grassroots network. We hear people brag about how much security BTC has. However, the marketcap for all of BTC is about $160B. Countries like the U.S. and China have GDP measured in many trillions; a trillion is 1,000 billion. Does 160B really seem untouchable? For numeric comparison the main U.S. federal food assistance program cost the government $70B in 2016, representing about 2% of the budget. So the entirety of the BTC market cap is about twice the size of one welfare program, representing 2% of the overall budget. Where should we place the current security power bars if we want guaranteed safety from a determined U.S. gov? If 50,000 is guaranteed safe we're far from it. I'd say BTC is more like 5,000. That's still pretty decent. Of course, BCH split from BTC... and didn't carry over all the miners and accompanying security. That's not an immediate concern because if BTC isn't on government's radar yet BCH sure isn't. However, that doesn't mean BCH doesn't need security from hostile forces. It's still a valuable network and needs defenses. Where would we put power bars for BCH? If BTC is 5,000 and BCH only has 3% of that hashrate then BCH has just 150. That's it. How the Developer Funding Plan Works Back to the DFP. What this says is as a community we agree to break off a piece of the block reward and instead of giving 100% to miners we give a small percent to developers. If each block is 10 coins and the price is $300 then winning a block means winning $3,000. Of course that's not all profit because miners have electricity and other expenses to pay before calculating profit. So if we reduce the portion of the miner reward by 10% so they get just 9 coins per block yet the price stays the same what happens? It means miners receive $2,700 for the same effort. We've just made it more expensive to mine BCH from the point of view of miners. What would any miner then rationally do? Seek profitability elsewhere if available. Suddenly BTC SHA256 hashing looks slightly more attractive so they'll go there. Hashrate leaves BCH and goes to BTC, but the key important point is BOTH chains have a difficulty adjustment algorithm which adjusts to account for rising or lowering miners overall, which keeps the coin inflation rate steady. This means BTC total hashrate rises (more miners compete for BTC) and its Difficulty Level rises accordingly, so the same rate of BTC pumps out; on BCH total hashrate falls (less miners compete for BCH) and its Difficulty falls, so the same rate of BCH pumps out. Inflation remains about the same on both coins so the price of both coins doesn't change any, beyond what it normally does based on news/events etc. So what difference is there? The difference is total network security. Hashrate totals have changed. BTC gains more miner securing hashrate while BCH loses it. So BTC goes from 5,000 to say 5,100 power bars. BCH goes from about 150 to 140. Does any of that matter in the grand scheme of things? Not in the slightest. Part of the reason is due to our emergency circumstances with BCH we had to rework our security model. Our primary defense is an idea I came up with, which BitcoinABC implemented, saying it's not sheer hashpower that dictates what chain we follow. We won't replace a chain we're working on if a new one suddenly appears if it means changing more than 10 blocks deep of history. This prevents all the threatening hashrate hanging over our heads from mining a secret chain and creating havoc unleashing it causing 10+ confimed txs to be undone, while exchanges, gambling sites etc. have long since paid out real world money. Switching $6M worth of block rewards from mining to devs just means we lose a bit of hashrate security, while we gain those funds for development. Nothing more. Nobody holding BCH pays in the form of inflation or any other way. It costs literally NOTHING BECAUSE The block reward is ALREADY ALLOCATED. It will EITHER go 100% to mining security if we do nothing, or go to both miners and devs if the plan is put into effect. Hopefully this helps. :) TL;DR: we switch security which we don't really need, for developer funding which we do.
simulating a long-term mining scenario - need help
I created a Bitcoin mining calculator in a form of a google spreadsheet to simulate various long-term (5 year period) mining outcomes.: calculator: link to spreadsheet Specific questions: 1) Beside the network difficulty (i), the mining hash rate (ii), and the block time (iii), the certain exchange rates (iv), and the power consumption indicators (v) is there any other parameter that could increase the precision of a real-time mining calculator? 2) Despite the 'spreads' between block validations, in the long term the protocol adjusts to the average 600 s block time, so I suppose that it is unnecessary - even wrong - to use a block time variable other than 10 mins. Is that correct? Directives / insights I would like to illustrate a plausible 5 years long mining scenario. I intend to make calculations for each day from today until the end of the 5 year period under investigation. I have to come up with solutions to the following problems .: A) I wish to simulate changes in the network difficulty. I think it wouldn't be wise to use a constantly increasing value. Do you have any suggestions about the actual test values and methods to calculate a realistic network difficulty scenario? B) I would like to designate theoretical dates of block reward halving in the following 5 years that are not unrealistic. What do you think? How many halvings are expected in the next 5 years, and approximately when? C) Finally, the most uncertain variable: the exchange rate of Bitcoin. Do you think that it is a good idea to mark a certain average value (e.g. $8.000) and use it as a constant reference for the entire 5 years period? Thank you very much for your help!
Is Hashocean Legit? Are there safer, comparable websites to invest in?
I recently invested into a website, Hashocean, trying my luck at the bitcoin market. Aside from being in Engrish, the website seems legit. I invested only money I made from faucets and my own feeble mining efforts to make sure it paid out before sinking in a few hundred dollars. Now I can't stop talking about it and my brother wants me to invest money on his behalf. I was worried enough about investing my own money, but now managing my brother's money makes me all the more wary about what I am investing in. Most of the reddit bitcoin posts go right over my head so it seems like people here know what they are talking about, and I've been reading up on a bit here and there, watching some videos to learn about it. Bitcoin, I'm not worried about. This website, possibly.
Hey everyone, I'm a finance graduate student with some experience trading crypto (majority bitcoin) since 2013. While prices have skyrocketed and created huge returns for holders, eventually, an actual understanding of bitcoin's valuation will have to emerge. My theory, and this may have been said by others, is that the cost of a bitcoin should approach the level where the award for mining a block equals the cost of mining that block. As classic economic models predict, as more firms (miners in this case) enter the market, they will be willing to work for less and less money, as long as they still cover the cost of electricity and computer chips. While I have no prediction when bitcoin will hit this level, I can say it is the lowest price that miners would be willing to accept, and therefore at least a floor on the price of BTC. Please share your thoughts and help improve this theory, thank you.
Many people may feel quite confused about their low profit now. Maybe you forget to think about the small details when you are mining. Small little details will make big difference in your final income. Now, i want to share you the 8 skills to improve your benefits. 1, Get a cheaper power Everyone knows the power is the most charge in mining, if we can find a cheaper electricity, it will be good. So, how to get a cheaper electricity? 55% of the mining is in China, and 40% of the mining is in Sichuan China. Why? Because there are many hydroelectric power station in there. So, you can find a place near the station and get a cheaper electricity from them. If you can find free electricity, it is the best anyway 2, Choose low w/t machine As you know, low comsuption machine is very popular those days, like S17 pro 53t, T17 42t. They are 7nm technical, the w/t is low and it can even overclock, it maybe a good choice. Also, we need to consider the price of machine. Cheap price machine means fast ROI, But low W/T machine has a bright future. 3, Buy miner when BTC begin to raise after long drop When BTC price keep falling, of course the machine will be cheaper and cheaper. When the BTC price begin to raise, we can buy miner at that time, because the price is the cheapset and you can earn money back soon. Normally at that time, the good machine will be sold out quickly, when the market feedback that those machine are good, you may be late to get the chance. So, make your plan for purchasing before, when price down, get them. 4, Do not forget BCH, BSV, ZEN coin Do remember SHA-256 Algorithm can mining BCH and BSV as well. Sometimes those coin may get even a better profits than BTC. Some miner has auto setting for BTC, but you can choose BSV and BCH mining if you set it, 5, Notice the half reward period information Because the half reward time is coming in 2020, there will be a chance or a risk for it. Many low hashrate machine may be out of the style and high hashrate will be more competitive. Low your risk and not to buy those cheap machine now 6, Choose a good future crypto currency There are many coins in this field now, we need to analyse and find a better direction for mining. Like Z11, many people use it for ZEN mining nowadays, and their benefits is top now. Also, people buy many S17, it can earn money back before next year half reward time. And they believe the BTC price will increase creazily as last two times. 7, Make plan for your selling of coin or machine As you know, the price of the BTC changes everytime, we can mining the BTC first and keep it in hand, do not sell it every day. It is very stupid. Just sell it when price high, you do not need to take any risk if you do not buy BTC directy. We do not need to care about the low price situation, we only need to wait. When chance come, get it. Same for machine 8. Don't be fooled by the mining calculator Many sites calculate mining profits based on hardware and electricity prices. If you've never mined before, you might be happy to see the numbers provided by these websites and calculators and think, "I'll make a fortune!" However, these websites don't tell you: in addition to the cost of electricity, there may be other current costs, such as maintenance, cooling, rent, labor, etc. Generally, the hash rate and power consumption of the device are slightly different from what the factory says. This difference is more common in unpopular brands. You can better understand the actual hash rate and the actual power consumption by watching the miner test video on YouTube. In addition, depending on the distance from the meter to the device and the type of cable used, the power loss from the meter to the device can be as high as 200 watts. In addition to the cost of mining machines, some initial costs are required to prepare the infrastructure, such as cooling and venting, cabling and distribution, shelves, network and monitoring equipment, safety measures, etc. The network difficulty is constantly changing and increasing at a significant speed, which directly affects the mining revenue. You can check the bitcoin network difficulty chart to see its growth rate, but your miner will not always be 100% active. Due to maintenance, network problems, ore pool problems, power problems and many other problems, the miner may be offline for several hours. I suggest that you consider setting the normal operation time of the miner to less than 97% when calculating. We have rich mining experience in professional ore pools, and the normal operation time of these mining machines will not exceed 97-98%. Thats all, hope those information will help you become a good mining investor.

Which are your Top 5 favourite coins out of the Top 100? An analysis.
I am putting together my investment portfolio for 2018 and made a complete summary of the current Top 100. Interestingly, I noticed that all coins can be categorized into 12 markets. Which markets do you think will play the biggest role in the coming year? Here is a complete overview of all coins in an excel sheet including name, market, TPS, risk profile, time since launch (negative numbers mean that they are launching that many months in the future) and market cap. You can also sort by all of these fields of course. Coins written in bold are the strongest contenders within their market either due to having the best technology or having a small market cap and still excellent technology and potential. https://docs.google.com/spreadsheets/d/1s8PHcNvvjuy848q18py_CGcu8elRGQAUIf86EYh4QZo/edit#gid=0 The 12 markets are

Before we look at the individual markets, we need to take a look of the overall market and its biggest issue scalability first: Cryptocurrencies aim to be a decentralized currency that can be used worldwide. Its goal is to replace dollar, Euro, Yen, all FIAT currencies worldwide. The coin that will achieve that will be worth several trillion dollars. Bitcoin can only process 7 transactions per second (TPS). In order to replace all FIAT, it would need to perform at at least VISA levels, which usually processes around 3,000 TPS, up to 25,000 TPS during peak times and a maximum of 64,000 TPS. That means that this cryptocurrency would need to be able to perform at least several thousand TPS. However, a ground breaking technology should not look at current technology to set a goal for its use, i.e. estimating the number of emails sent in 1990 based on the number of faxes sent wasn’t a good estimate. For that reason, 10,000 TPS is the absolute baseline for a cryptocurrency that wants to replace FIAT. This brings me to IOTA, which wants to connect all 80 billion IoT devices that are expected to exist by 2025, which constantly communicate with each other, creating 80 billion or more transactions per second. This is the benchmark that cryptocurrencies should be aiming for. Currently, 8 billion devices are connected to the Internet. With its Lightning network recently launched, Bitcoin is realistically looking at 50,000 possible soon. Other notable cryptocurrencies besides IOTA and Bitcoin are Nano with 7,000 TPS already tested, Dash with several billion TPS possible with Masternodes, Neo, LISK and RHOC with 100,000 TPS by 2020, Ripple with 50,000 TPS, Ethereum with 10,000 with Sharding. However, it needs to be said that scalability usually goes at the cost of decentralization and security. So, it needs to be seen, which of these technologies can prove itself resilient and performant. Without further ado, here are the coins of the first market
Market 1 - Currency:
Bitcoin: 1st generation blockchain with currently bad scalability currently, though the implementation of the Lightning Network looks promising and could alleviate most scalability concerns, scalability and high energy use.
Ripple: Centralized currency that might become very successful due to tight involvement with banks and cross-border payments for financial institutions; banks and companies like Western Union and Moneygram (who they are currently working with) as customers customers. However, it seems they are aiming for more decentralization now.https://ripple.com/dev-blog/decentralization-strategy-update/. Has high TPS due to Proof of Correctness algorithm.
Bitcoin Cash: Bitcoin fork with the difference of having an 8 times bigger block size, making it 8 times more scalable than Bitcoin currently. Further block size increases are planned. Only significant difference is bigger block size while big blocks lead to further problems that don't seem to do well beyond a few thousand TPS. Opponents to a block size argue that increasing the block size limit is unimaginative, offers only temporary relief, and damages decentralization by increasing costs of participation. In order to preserve decentralization, system requirements to participate should be kept low. To understand this, consider an extreme example: very big blocks (1GB+) would require data center level resources to validate the blockchain. This would preclude all but the wealthiest individuals from participating.Community seems more open than Bitcoin's though.
Litecoin : Little brother of Bitcoin. Bitcoin fork with different mining algorithm but not much else.Copies everything that Bitcoin does pretty much. Lack of real innovation.
Dash: Dash (Digital Cash) is a fork of Bitcoin and focuses on user ease. It has very fast transactions within seconds, low fees and uses Proof of Service from Masternodes for consensus. They are currently building a system called Evolution which will allow users to send money using usernames and merchants will find it easy to integrate Dash using the API. You could say Dash is trying to be a PayPal of cryptocurrencies. Currently, cryptocurrencies must choose between decentralization, speed, scalability and can pick only 2. With Masternodes, Dash picked speed and scalability at some cost of decentralization, since with Masternodes the voting power is shifted towards Masternodes, which are run by Dash users who own the most Dash.
IOTA: 3rd generation blockchain called Tangle, which has a high scalability, no fees and instant transactions. IOTA aims to be the connective layer between all 80 billion IOT devices that are expected to be connected to the Internet in 2025, possibly creating 80 billion transactions per second or 800 billion TPS, who knows. However, it needs to be seen if the Tangle can keep up with this scalability and iron out its security issues that have not yet been completely resolved.
Nano: 3rd generation blockchain called Block Lattice with high scalability, no fees and instant transactions. Unlike IOTA, Nano only wants to be a payment processor and nothing else, for now at least. With Nano, every user has their own blockchain and has to perform a small amount of computing for each transaction, which makes Nano perform at 300 TPS with no problems and 7,000 TPS have also been tested successfully. Very promising 3rd gen technology and strong focus on only being the fastest currency without trying to be everything.
Decred: As mining operations have grown, Bitcoin’s decision-making process has become more centralized, with the largest mining companies holding large amounts of power over the Bitcoin improvement process. Decred focuses heavily on decentralization with their PoW Pos hybrid governance system to become what Bitcoin was set out to be. They will soon implement the Lightning Network to scale up. While there do not seem to be more differences to Bitcoin besides the novel hybrid consensus algorithm, which Ethereum, Aeternity and Bitcoin Atom are also implementing, the welcoming and positive Decred community and professoinal team add another level of potential to the coin.
Aeternity: We’ve seen recently, that it’s difficult to scale the execution of smart contracts on the blockchain. Crypto Kitties is a great example. Something as simple as creating and trading unique assets on Ethereum bogged the network down when transaction volume soared. Ethereum and Zilliqa address this problem with Sharding. Aeternity focuses on increasing the scalability of smart contracts and dapps by moving smart contracts off-chain. Instead of running on the blockchain, smart contracts on Aeternity run in private state channels between the parties involved in the contracts. State channels are lines of communication between parties in a smart contract. They don’t touch the blockchain unless they need to for adjudication or transfer of value. Because they’re off-chain, state channel contracts can operate much more efficiently. They don’t need to pay the network for every time they compute and can also operate with greater privacy. An important aspect of smart contract and dapp development is access to outside data sources. This could mean checking the weather in London, score of a football game, or price of gold. Oracles provide access to data hosted outside the blockchain. In many blockchain projects, oracles represent a security risk and potential point of failure, since they tend to be singular, centralized data streams. Aeternity proposes decentralizing oracles with their oracle machine. Doing so would make outside data immutable and unchangeable once it reaches Aeternity’s blockchain. Of course, the data source could still be hacked, so Aeternity implements a prediction market where users can bet on the accuracy and honesty of incoming data from various oracles.It also uses prediction markets for various voting and verification purposes within the platform. Aeternity’s network runs on on a hybrid of proof of work and proof of stake. Founded by a long-time crypto-enthusiast and early colleague of Vitalik Buterin, Yanislav Malahov. Promising concept though not product yet
Bitcoin Atom: Atomic Swaps and hybrid consenus. This looks like the only Bitcoin clone that actually is looking to innovate next to Bitcoin Cash.
Dogecoin: Litecoin fork, fantastic community, though lagging behind a bit in technology.
Bitcoin Gold: A bit better security than bitcoin through ASIC resistant algorithm, but that's it. Not that interesting.
Digibyte: Digibyte's PoS blockchain is spread over a 100,000+ servers, phones, computers, and nodes across the globe, aiming for the ultimate level of decentralization. DigiByte rebalances the load between the five mining algorithms by adjusting the difficulty of each so one algorithm doesn’t become dominant. The algorithm's asymmetric difficulty has gained notoriety and been deployed in many other blockchains.DigiByte’s adoption over the past four years has been slow. It’s still a relatively obscure currency compared its competitors. The DigiByte website offers a lot of great marketing copy and buzzwords. However, there’s not much technical information about what they have planned for the future. You could say Digibyte is like Bitcoin, but with shorter blocktimes and a multi-algorithm. However, that's not really a difference big enough to truly set themselves apart from Bitcoin, since these technologies could be implemented by any blockchain without much difficulty. Their decentralization is probably their strongest asset, however, this also change quickly if the currency takes off and big miners decide to go into Digibyte.
Bitcoin Diamond Asic resistant Bitcoin and Copycat
Market 2 - Platform
Most of the cryptos here have smart contracts and allow dapps (Decentralized apps) to be build on their platform and to use their token as an exchange of value between dapp services.
Ethereum: 2nd generation blockchain that allows the use of smart contracts. Bad scalability currently, though this concern could be alleviated by the soon to be implemented Lightning Network aka Plasma and its Sharding concept.
EOS: Promising technology that wants to be able do everything, from smart contracts like Ethereum, scalability similar to Nano with 1000 tx/second + near instant transactions and zero fees, to also wanting to be a platform for dapps. However, EOS doesn't have a product yet and everything is just promises still. Highly overvalued right now. However, there are lots of red flags, have dumped $500 million Ether over the last 2 months and possibly bought back EOS to increase the size of their ICO, which has been going on for over a year and has raised several billion dollars. All in all, their market cap is way too high for that and not even having a product.
Cardano: Similar to Ethereum/EOS, however, only promises made with no delivery yet, highly overrated right now. Interesting concept though. Market cap way too high for not even having a product. Somewhat promising technology.
VeChain: Singapore-based project that’s building a business enterprise platform and inventory tracking system. Examples are verifying genuine luxury goods and food supply chains. Has one of the strongest communities in the crypto world. Most hyped token of all, with merit though.
Neo: Neo is a platform, similar to Eth, but more extensive, allowing dapps and smart contracts, but with a different smart contract gas system, consensus mechanism (PoS vs. dBfT), governance model, fixed vs unfixed supply, expensive contracts vs nearly free contracts, different ideologies for real world adoption. There are currently only 9 nodes, each of which are being run by a company/entity hand selected by the NEO council (most of which are located in china) and are under contract. This means that although the locations of the nodes may differ, ultimately the neo council can bring them down due to their legal contracts. In fact this has been done in the past when the neo council was moving 50 million neo that had been locked up. Also dbft (or neo's implmentation of it) has failed underload causing network outages during major icos. The first step in decentralization is that the NEO Counsel will select trusted nodes (Universities, business partners, etc.) and slowly become less centralized that way. The final step in decentralization will be allowing NEO holders to vote for new nodes, similar to a DPoS system (ARK/EOS/LISK). NEO has a regulation/government friendly ideology. Finally they are trying to work undewith the Chinese government in regards to regulations. If for some reason they wanted it shut down, they could just shut it down.
Stellar: PoS system, similar goals as Ripple, but more of a platform than only a currency. 80% of Stellar are owned by Stellar.org still, making the currency centralized.
Ethereum classic: Original Ethereum that decided not to fork after a hack. The Ethereum that we know is its fork. Uninteresing, because it has a lot of less resources than Ethereum now and a lot less community support.
Ziliqa: Zilliqa is building a new way of sharding. 2400 tpx already tested, 10,000 tps soon possible by being linearly scalable with the number of nodes. That means, the more nodes, the faster the network gets. They are looking at implementing privacy as well.
QTUM: Enables Smart contracts on the Bitcoin blockchain. Useful.
Icon: Korean ethereum. Decentralized application platform that's building communities in partnership with banks, insurance providers, hospitals, and universities. Focused on ID verification and payments. No big differentiators to the other 20 Ethereums, except that is has a product. That is a plus. Maybe cheap alternative to Ethereum.
LISK: Lisk's difference to other BaaS is that side chains are independent to the main chain and have to have their own nodes. Similar to neo whole allows dapps to deploy their blockchain to. However, Lisk is currently somewhat centralized with a small group of members owning more than 50% of the delegated positions. Lisk plans to change the consensus algorithm for that reason in the near future.
Rchain: Similar to Ethereum with smart contract, though much more scalable at an expected 40,000 TPS and possible 100,000 TPS. Not launched yet. No product launched yet, though promising technology. Not overvalued, probably at the right price right now.
ARDR: Similar to Lisk. Ardor is a public blockchain platform that will allow people to utilize the blockchain technology of Nxt through the use of child chains. A child chain, which is a ‘light’ blockchain that can be customized to a certain extent, is designed to allow easy self-deploy for your own blockchain. Nxt claims that users will "not need to worry" about security, as that part is now handled by the main chain (Ardor). This is the chief innovation of Ardor. Ardor was evolved from NXT by the same company. NEM started as a NXT clone.
Ontology: Similar to Neo. Interesting coin
Bytom: Bytom is an interactive protocol of multiple byte assets. Heterogeneous byte-assets (indigenous digital currency, digital assets) that operate in different forms on the Bytom Blockchain and atomic assets (warrants, securities, dividends, bonds, intelligence information, forecasting information and other information that exist in the physical world) can be registered, exchanged, gambled and engaged in other more complicated and contract-based interoperations via Bytom.
Nxt: Similar to Lisk
Stratis: Different to LISK, Stratis will allow businesses and organizations to create their own blockchain according to their own needs, but secured on the parent Stratis chain. Stratis’s simple interface will allow organizations to quickly and easily deploy and/or test blockchain functionality of the Ethereum, BitShares, BitCoin, Lisk and Stratis environements.
Status: Status provides access to all of Ethereum’s decentralized applications (dapps) through an app on your smartphone. It opens the door to mass adoption of Ethereum dapps by targeting the fastest growing computer segment in the world – smartphone users.16. Ark: Fork of Lisk that focuses on a smaller feature set. Ark wallets can only vote for one delegate at a time which forces delegates to compete against each other and makes cartel formations incredibly hard, if not impossible.
Neblio: Similar to Neo, but 30x smaller market cap.
NEM: Is similar to Neo No marketing team, very high market cap for little clarilty what they do.
Bancor: Bancor is a Decentralized Liquidity Network that allows you to hold any Ethereum token and convert it to any other token in the network, with no counter party, at an automatically calculated price, using a simple web wallet.
Dragonchain: The Purpose of DragonChain is to help companies quickly and easily incorporate blockchain into their business applications. Many companies might be interested in making this transition because of the benefits associated with serving clients over a blockchain – increased efficiency and security for transactions, a reduction of costs from eliminating potential fraud and scams, etc.
Skycoin: Transactions with zero fees that take apparently two seconds, unlimited transaction rate, no need for miners and block rewards, low power usage, all of the usual cryptocurrency technical vulnerabilities fixed, a consensus mechanism superior to anything that exists, resistant to all conceivable threats (government censorship, community infighting, cybenucleaconventional warfare, etc). Skycoin has their own consensus algorithm known as Obelisk written and published academically by an early developer of Ethereum. Obelisk is a non-energy intensive consensus algorithm based on a concept called ‘web of trust dynamics’ which is completely different to PoW, PoS, and their derivatives. Skywire, the flagship application of Skycoin, has the ambitious goal of decentralizing the internet at the hardware level and is about to begin the testnet in April. However, this is just one of the many facets of the Skycoin ecosystem. Skywire will not only provide decentralized bandwidth but also storage and computation, completing the holy trinity of commodities essential for the new internet. Skycion a smear campaign launched against it, though they seem legit and reliable. Thus, they are probably undervalued.
Market 3 - Ecosystem
The 3rd market with 11 coins is comprised of ecosystem coins, which aim to strengthen the ease of use within the crypto space through decentralized exchanges, open standards for apps and more
Nebulas: Similar to how Google indexes webpages Nebulas will index blockchain projects, smart contracts & data using the Nebulas rank algorithm that sifts & sorts the data. Developers rewarded NAS to develop & deploy on NAS chain. Nebulas calls this developer incentive protocol – basically rewards are issued based on how often dapp/contract etc. is used, the more the better the rewards and Proof of devotion. Works like DPoS except the best, most economically incentivised developers (Bookkeeppers) get the forging spots. Ensuring brains stay with the project (Cross between PoI & PoS). 2,400 TPS+, DAG used to solve the inter-transaction dependencies in the PEE (Parallel Execution Environment) feature, first crypto Wallet that supports the Lightening Network.
Waves: Decentralized exchange and crowdfunding platform. Let’s companies and projects to issue and manage their own digital coin tokens to raise money.
Salt: Leveraging blockchain assets to secure cash loands. Plans to offer cash loans in traditional currencies, backed by your cryptocurrency assets. Allows lenders worldwide to skip credit checks for easier access to affordable loans.
CHAINLINK: ChainLink is a decentralized oracle service, the first of its kind. Oracles are defined as an ‘agent’ that finds and verifies real-world occurrences and submits this information to a blockchain to be used in smart contracts.With ChainLink, smart contract users can use the network’s oracles to retrieve data from off-chain application program interfaces (APIs), data pools, and other resources and integrate them into the blockchain and smart contracts. Basically, ChainLink takes information that is external to blockchain applications and puts it on-chain. The difference to Aeternity is that Chainlink deploys the smart contracts on the Ethereum blockchain while Aeternity has its own chain.
WTC: Combines blockchain with IoT to create a management system for supply chains Interesting
Ethos unifyies all cryptos. Ethos is building a multi-cryptocurrency phone wallet. The team is also building an investment diversification tool and a social network
Aion: Aion is the token that pays for services on the Aeternity platform.
USDT: is no cryptocurrency really, but a replacement for dollar for trading After months of asking for proof of dollar backing, still no response from Tether.
Market 4 - Privacy
The 4th market are privacy coins. As you might know, Bitcoin is not anonymous. If the IRS or any other party asks an exchange who is the identity behind a specific Bitcoin address, they know who you are and can track back almost all of the Bitcoin transactions you have ever made and all your account balances. Privacy coins aim to prevent exactly that through address fungability, which changes addresses constantly, IP obfuscation and more. There are 2 types of privacy coins, one with completely privacy and one with optional privacy. Optional Privacy coins like Dash and Nav have the advantage of more user friendliness over completely privacy coins such as Monero and Enigma.
Monero: Currently most popular privacy coin, though with a very high market cap. Since their privacy is all on chain, all prior transactions would be deanonymized if their protocol is ever cracked. This requires a quantum computing attack though. PIVX is better in that regard.
Zcash: A decentralized and open-source cryptocurrency that hide the sender, recipient, and value of transactions. Offers users the option to make transactions public later for auditing. Decent privacy coin, though no default privacy
Verge: Calls itself privacy coin without providing private transactions, multiple problems over the last weeks has a toxic community, and way too much hype for what they have.
Bytecoin: First privacy-focused cryptocurrency with anonymous transactions. Bytecoin’s code was later adapted to create Monero, the more well-known anonymous cryptocurrency. Has several scam accusations, 80% pre-mine, bad devs, bad tech
Bitcoin Private: A merge fork of Bitcoin and Zclassic with Zclassic being a fork of Zcash with the difference of a lack of a founders fee required to mine a valid block. This promotes a fair distribution, preventing centralized coin ownership and control. Bitcoin private offers the optional ability to keep the sender, receiver, and amount private in a given transaction. However, this is already offered by several good privacy coins (Monero, PIVX) and Bitcoin private doesn't offer much more beyond this.
Komodo: The Komodo blockchain platform uses Komodo’s open-source cryptocurrency for doing transparent, anonymous, private, and fungible transactions. They are then made ultra-secure using Bitcoin’s blockchain via a Delayed Proof of Work (dPoW) protocol and decentralized crowdfunding (ICO) platform to remove middlemen from project funding. Offers services for startups to create and manage their own Blockchains.
PIVX: As a fork of Dash, PIVX uses an advanced implementation of the Zerocoin protocol to provide it’s privacy. This is a form of zeroknowledge proofs, which allow users to spend ‘Zerocoins’ that have no link back to them. Unlike Zcash u have denominations in PIVX, so they can’t track users by their payment amount being equal to the amount of ‘minted’ coins, because everyone uses the same denominations. PIVX is also implementing Bulletproofs, just like Monero, and this will take care of arguably the biggest weakness of zeroknowledge protocols: the trusted setup.
Zcoin: PoW cryptocurrency. Private financial transactions, enabled by the Zerocoin Protocol. Zcoin is the first full implementation of the Zerocoin Protocol, which allows users to have complete privacy via Zero-Knowledge cryptographic proofs.
Enigma: Monero is to Bitcoin what enigma is to Ethereum. Enigma is for making the data used in smart contracts private. More of a platform for dapps than a currency like Monero. Very promising.
Navcoin: Like bitcoin but with added privacy and pos and 1,170 tps, but only because of very short 30 second block times. Though, privacy is optional, but aims to be more user friendly than Monero. However, doesn't really decide if it wants to be a privacy coin or not. Same as Zcash.Strong technology, non-shady team.
Tenx: Raised 80 million, offers cryptocurrency-linked credit cards that let you spend virtual money in real life. Developing a series of payment platforms to make spending cryptocurrency easier. However, the question is if full privacy coins will be hindered in growth through government regulations and optional privacy coins will become more successful through ease of use and no regulatory hindrance.
Market 5 - Currency Exchange Tool
Due to the sheer number of different cryptocurrencies, exchanging one currency for the other it still cumbersome. Further, merchants don’t want to deal with overcluttered options of accepting cryptocurrencies. This is where exchange tool like Req come in, which allow easy and simple exchange of currencies.
Cryptonex: Fiat and currency exchange between various blockchain services, similar to REQ.
QASH: Qash is used to fuel its liquid platform which will be an exchange that will distribute their liquidity pool. Its product, the Worldbook is a multi-exchange order book that matches crypto to crypto, and crypto to fiat and the reverse across all currencies. E.g., someone is selling Bitcoin is USD on exchange1 not owned by Quoine and someone is buying Bitcoin in EURO on exchange 2 not owned by Quoine. If the forex conversions and crypto conversions match then the trade will go through and the Worldbook will match it, it'll make the sale and the purchase on either exchange and each user will get what they wanted, which means exchanges with lower liquidity if they join the Worldbook will be able to fill orders and take trade fees they otherwise would miss out on.They turned it on to test it a few months ago for an hour or so and their exchange was the top exchange in the world by 4x volume for the day because all Worldbook trades ran through it. Binance wants BNB to be used on their one exchange. Qash wants their QASH token embedded in all of their partners. More info here https://www.reddit.com/CryptoCurrency/comments/8a8lnwhich_are_your_top_5_favourite_coins_out_of_the/dwyjcbb/?context=3
Kyber: network Exchange between cryptocurrencies, similar to REQ. Features automatic coin conversions for payments. Also offers payment tools for developers and a cryptocurrency wallet.
Achain: Building a boundless blockchain world like Req .
Req: Exchange between cryptocurrencies.
Bitshares: Exchange between cryptocurrencies. Noteworthy are the 1.5 second average block times and throughput potential of 100,000 transactions per second with currently 2,400 TPS having been proven. However, bitshares had several Scam accusations in the past.
Loopring: A protocol that will enable higher liquidity between exchanges and personal wallets.
ZRX: Open standard for dapps. Open, permissionless protocol allowing for ERC20 tokens to be traded on the Ethereum blockchain. In 0x protocol, orders are transported off-chain, massively reducing gas costs and eliminating blockchain bloat. Relayers help broadcast orders and collect a fee each time they facilitate a trade. Anyone can build a relayer.
Market 6 - Gaming
With an industry size of $108B worldwide, Gaming is one of the largest markets in the world. For sure, cryptocurrencies will want to have a share of that pie.
Storm: Mobile game currency on a platform with 9 million players.
Fun: A platform for casino operators to host trustless, provably-fair gambling through the use of smart contracts, as well as creating their own implementation of state channels for scalability.
Electroneum: Mobile game currency They have lots of technical problems, such as several 51% attacks
Wax: Marketplace to trade in-game items
Market 7 - Misc
There are various markets being tapped right now. They are all summed up under misc.
OMG: Omise is designed to enable financial services for people without bank accounts. It works worldwide and with both traditional money and cryptocurrencies.
Power ledger: Australian blockchain-based cryptocurrency and energy trading platform that allows for decentralized selling and buying of renewable energy. Unique market and rather untapped market in the crypto space.
Populous: A platform that connects business owners and invoice buyers without middlemen. Invoice sellers get cash flow to fund their business and invoice buyers earn interest. Similar to OMG, small market.
Monacoin: The first Japanese cryptocurrency. Focused on micro-transactions and based on a popular internet meme of a type-written cat. This makes it similar to Dogecoin. Very niche, tiny market.
Revain: Legitimizing reviews via the blockchain. Interesting concept, though market not as big.
Augur: Platform to forecast and make wagers on the outcome of real-world events (AKA decentralized predictions). Uses predictions for a “wisdom of the crowd” search engine. Not launched yet.
Substratum: Revolutionzing hosting industry via per request billing as a decentralized internet hosting system. Uses a global network of private computers to create the free and open internet of the future. Participants earn cryptocurrency. Interesting concept.
Veritaseum: Is supposed to be a peer to peer gateway, though it looks like very much like a scam.
TRON: Tronix is looking to capitalize on ownership of internet data to content creators. However, they plagiarized their white paper, which is a no go. They apologized, so it needs to be seen how they will conduct themselves in the future. Extremely high market cap for not having a product, nor proof of concept.
Syscoin: A cryptocurrency with a decentralized marketplace that lets people buy and sell products directly without third parties. Trying to remove middlemen like eBay and Amazon.
Hshare: Most likely scam because of no code changes, most likely pump and dump scheme, dead community.
BAT: An Ethereum-based token that can be exchanged between content creators, users, and advertisers. Decentralized ad-network that pays based on engagement and attention.
Dent: Decentralizeed exchange of mobile data, enabling mobile data to be marketed, purchased or distributed, so that users can quickly buy or sell data from any user to another one.
Ncash: End to end encrypted Identification system for retailers to better serve their customers .
Factom Secure record-keeping system that allows companies to store their data directly on the Blockchain. The goal is to make records more transparent and trustworthy .
Market 8 - Social network
Web 2.0 is still going strong and Web 3.0 is not going to ignore it. There are several gaming tokens already out there and a few with decent traction already, such as Steem, which is Reddit with voting through money is a very interesting one.
Mithril: As users create content via social media, they will be rewarded for their contribution, the better the contribution, the more they will earn
Steem: Like Reddit, but voting with money. Already launched product and Alexa rank 1,000 Thumbs up.
Rdd: Reddcoin makes the process of sending and receiving money fun and rewarding for everyone. Reddcoin is dedicated to one thing – tipping on social networks as a way to bring cryptocurrency awareness and experience to the general public.
Kin: Token for the platform Kik. Kik has a massive user base of 400 million people. Replacing paying with FIAT with paying with KIN might get this token to mass adoption very quickly.
Market 9 - Fee token
Popular exchanges realized that they can make a few billion dollars more by launching their own token. Owning these tokens gives you a reduction of trading fees. Very handy and BNB (Binance Coin) has been one of the most resilient tokens, which have withstood most market drops over the last weeks and was among the very few coins that could show growth.
BNB: Fee token for Binance
Gas: Not a Fee token for an exchange, but it is a dividend paid out on Neo and a currency that can be used to purchase services for dapps.
Kucoin: Fee token for Kucoin
Market 10 - Decentralized Data Storage
Currently, data storage happens with large companies or data centers that are prone to failure or losing data. Decentralized data storage makes loss of data almost impossible by distributing your files to numerous clients that hold tiny pieces of your data. Remember Torrents? Torrents use a peer-to-peer network. It is similar to that. Many users maintain copies of the same file, when someone wants a copy of that file, they send a request to the peer-to-peer network., users who have the file, known as seeds, send fragments of the file to the requester., he requester receives many fragments from many different seeds, and the torrent software recompiles these fragments to form the original file.
Gbyte: Byteball data is stored and ordered using directed acyclic graph (DAG) rather than blockchain. This allows all users to secure each other's data by referencing earlier data units created by other users, and also removes scalability limits common for blockchains, such as blocksize issue.
Siacoin: Siacoin is decentralized storage platform. Distributes encrypted files to thousands of private users who get paid for renting out their disk space. Anybody with siacoins can rent storage from hosts on Sia. This is accomplish via "smart" storage contracts stored on the Sia blockchain. The smart contract provides a payment to the host only after the host has kept the file for a given amount of time. If the host loses the file, the host does not get paid.
Maidsafecoin: MaidSafe stands for Massive Array of Internet Disks, Secure Access for Everyone.Instead of working with data centers and servers that are common today and are vulnerable to data theft and monitoring, SAFE’s network uses advanced P2P technology to bring together the spare computing capacity of all SAFE users and create a global network. You can think of SAFE as a crowd-sourced internet. All data and applications reside in this network. It’s an autonomous network that automatically sets prices and distributes data and rents out hard drive disk space with a Blockchain-based storage solutions.When you upload a file to the network, such as a photo, it will be broken into pieces, hashed, and encrypted. The data is then randomly distributed across the network. Redundant copies of the data are created as well so that if someone storing your file turns off their computer, you will still have access to your data. And don’t worry, even with pieces of your data on other people’s computers, they won’t be able to read them. You can earn MadeSafeCoins by participating in storing data pieces from the network on your computer and thus earning a Proof of Resource.
Storj: Storj aims to become a cloud storage platform that can’t be censored or monitored, or have downtime. Your files are encrypted, shredded into little pieces called 'shards', and stored in a decentralized network of computers around the globe. No one but you has a complete copy of your file, not even in an encrypted form.
Market 11 - Cloud computing
Obviously, renting computing power, one of the biggest emerging markets as of recent years, e.g. AWS and Digital Ocean, is also a service, which can be bought and managed via the blockchain.
Golem: Allows easy use of Supercomputer in exchange for tokens. People worldwide can rent out their computers to the network and get paid for that service with Golem tokens.
Elf: Allows easy use of Cloud computing in exchange for tokens.
Market 12 - Stablecoin
Last but not least, there are 2 stablecoins that have established themselves within the market. A stable coin is a coin that wants to be independent of the volatility of the crypto markets. This has worked out pretty well for Maker and DGD, accomplished through a carefully diversified currency fund and backing each token by 1g or real gold respectively. DO NOT CONFUSE DGD AND MAKER with their STABLE COINS DGX and DAI. DGD and MAKER are volatile, because they are the companies of DGX and DAI. DGX and DAI are the stable coins.
DGD: Platform of the Stablecoin DGX. Every DGX coin is backed by 1g of gold and make use proof of asset consensus.
Maker: Platform of the Stablecoin DAI that doesn't vary much in price through widespread and smart diversification of assets.
EDIT: Added a risk factor from 0 to 10. The baseline is 2 for any crypto. Significant scandals, mishaps, shady practices, questionable technology, increase the risk factor. Not having a product yet automatically means a risk factor of 6. Strong adoption and thus strong scrutiny or positive community lower the risk factor. EDIT2: Added a subjective potential factor from 0 to 10, where its overall potential and a small or big market cap is factored in. Bitcoin with lots of potential only gets a 9, because of its massive market cap, because if Bitcoin goes 10x, smaller coins go 100x, PIVX gets a 10 for being as good as Monero while carrying a 10x smaller market cap, which would make PIVX go 100x if Monero goes 10x.
A Dead Simple Block Explorer for Bitcoin Newcoiners
Coin Ninja is very excited to announce our recently revamped Block Explorer and News Portal, accessible on Coinninja.com. We redesigned our blockexplorer in an effort to help meet our company goal: Turning NOcoiners into NEWcoiners into everyday Bitcoin users. TLDR
Made for Newcoiners who just need the basics
Most important stats right up front (price, current fees, current average confirmation time)
Transactions look like receipt to help them understand why to search a transaction on a blockchain
Easy to understand incoming transaction viewer
Let's get in to the details... https://preview.redd.it/kq74df328ma21.png?width=1674&format=png&auto=webp&s=c6bf64088192adc901ab271ea4ed82afd3cc974b Our strategy behind the block explorer design and user experience was simple - make it much more inviting and less intimidating to newcoiners. While many other block explorers are well done for experienced crypto enthusiasts, they are overly complex for the masses to understand. The abundance of information coupled with the crypt-nomenclature is enough to scare away anyone who's just trying to verify the status of a transaction. Initial View: Stripping down to just the Essential Information Each piece of data associated with transactions — fees, hash rate, difficulty, block height etc are all important and informative, but to the lay person first taking a look at it’s altogether confusing. We want people to come to our block explorer and have a simplified view of only the basic details of a transaction, all organized in a modular, receipt like view that people are familiar with:

We'll continue to listen to feedback to see if we've hit the mark on the balance of simplicity and just the right amount of detail. Additional Features In addition, we have displayed some very high level stats about the Bitcoin blockchain that are easily consumable but helpful for people to learn and understand. These include:
Cost to send
Average transaction time
A Bitcoin Calculator (allow users to input a BTC value and see the equivalent $USD value calculation)
A fun transaction viewer that updates every second with a visual showing how active the Bitcoin network is and the amounts that are being transacted in
And of course, there are still several helpful resources that users can explore (videos, infographics, and news articles) as well. Please take a look and let us know what you think - Coinninja.com. We'd love to hear feedback to continue to try to bring more people into the crypto space.
