Full analysis of the Filecoin big miner test (updated in real time on August 21)



Now the Filecoin big miner test has been finalized for August 25, 2020 (next Tuesday, Qixi Festival). I won’t say much about the popularity of Filecoin, and the delay in launching the mainnet has not only failed to dampen everyone’s enthusiasm, but has also whetted the appetite of miners. After the big miner test, the main network will be launched immediately. This article will briefly explain the big miner test (known as the Space Race). Explain in terms of time, place, person, and event. The time and event section will expand the details. According to time, place, person, event, let's explain it. The time and event section will expand the details. Contents of this article: Start time and end time Order acceptance rate problem Bandwidth problem Characters (participants) Miner supply chain quantity and distribution Reward pool detailed explanation Reward release principle Whether customers who have purchased computing power can get rewards Key parameters: Pledge rate time is large When did the miner test start? It was officially announced on August 25 that the space test will officially start at 6 am on August 25, Beijing time. The top 100 miners in the world and the top 50 miners in each continent will be based on their storage capacity during the competition and the network. Earn Filecoin rewards. Once the race starts, progress can be tracked at Security reminder: Beware of Filecoin RBF fake recharge attacks: According to the slow fog news, Filecoin has "double-spend transactions", and many exchanges have closed FIL recharge channels. The SlowMist security team analyzed relevant information and found that this was a Filecoin RBF fake recharge attack rather than a "double spend attack". The attacker sends a low gas-feecap transaction in advance, and then replaces the original transaction (RBF transaction) by increasing the gas-premium and gas-feecap. At this time, the RBF transaction is first packaged on the chain, and the old transaction is discarded. However, due to FilecoinlotusRPC A feature, when querying the execution status of the old transaction (using the lotusstateexec-trace command or through the REST interface Filecoin.StateGetReceipt), the return is the execution status of the RBF transaction, causing the exchange to double-entry the two transactions. The SlowMist security team reminds exchanges and relevant wallets that when recharging into accounts, it is necessary to compare whether the cid in the query return result is consistent with the cid in the query, and cooperate with ChainGetParentMessages and ChainGetParentReceipts to query and compare to avoid double entry. Different from the fake recharge attack found in the slow fog area before, this attack method is more subtle, which is caused by the characteristics of Filecoin nodes. Exchanges and related wallets should check the recharge and entry procedures again. For verification of fields such as To, Value, transfer type Method, and execution result ExitCode, if necessary, please ask a security audit company to assist in the detection. [2021/3/19 19:00:10] When will it end? The current effective computing power of the Filecoin network is 2.08EiB: According to, Filfox browser data shows that the current block height of the Filecoin network is 441724, the effective computing power of the entire network is 2.080EiB, and the total pledge amount is about 32.85 million FIL, the number of active-ethexc miners is 1192, the reward per block is 19.3735FIL, the output in the past 24 hours is 270424FIL, and the average mining income in 24 hours is 0.1253FIL/TiB. At present, the top three effective computing power are: F01248 (Zhihe Yunzh) temporarily ranks first with 74.45PiB, F02770 (Time Space Cloud & Smart) ranks second with 72.63PiB, and F09652 (RRmine) ranks with 52.48PiB third. [2021/1/25 13:26:15] The test period of the big miner is 21 days, that is, three weeks. Space Race Eligibility Participating miners must respond to storage and retrieval transaction requests from orderbots with a success rate of 80% or above. Note that if the success rate of the order robot is less than 80%, the qualification will be disqualified. The problem of order acceptance rate The storage order deal of the big miner test must be sent through the official dealbot (order robot) of filecoin. Robot location is in Europe (not in China). Chinese miners need a VPN (Scientific Internet Access) to receive orders, and it is difficult to receive deals without a VPN. Juan, the founder of Filecoin: It is speculated that Sun Yuchen may take the opportunity to fork Filecoin: On October 20, Filecoin founder Juan Benet (Juan Benet) tweeted that he speculated that Sun Yuchen’s previous remarks were to take the opportunity to fork Filecoin. (Note: Earlier, Justin Sun tweeted that he hoped that the SEC would investigate the event that Filecoin officially sold 1.5 million FIL). Juan also said: Sun Yuchen is not anyone's savior, just ask Hive. If he does fork, I will give some advice to miners who consider joining: review all previous Tron-related projects, are you sure you want to fall victim to a scam project? Wish ya'll good luck! [2020/10/20] Bandwidth problem The order is only a response problem, and does not require excessive bandwidth, which is the same as normal mining requirements. As long as you can receive the order requirements, it is OK. Different places have different network speed requirements. Because there is no need for retrieval, the requirements for network speed are mainly reflected in the CDN distribution level. However, there are certain requirements, which are not critical but must be met. After all, the distance of the physical address has a small impact on the order receiving efficiency. Remarks: The current mining order is mainly based on archive storage. The process of encryption and decryption is not very friendly to hot storage. A video 1G, upload encryption, sector sealing, zk-SNARKs Bellman and other processes will be relatively slow. Encryption takes a while, and decryption may take several hours, which seems to be very troublesome, so there is no commercial use. It has been a long time but the fee is low, and there is a glimmer of hope for the application to land here. BiKi leveraged ETF zone has launched FIL3L/FIL3S: According to the BiKi platform announcement, the leveraged ETF zone is now open for FIL3L (that is, 3 times long FIL), FIL3S (that is, 3 times short FIL) trading pairs. Leveraged ETF3L/3S is an index fund that anchors the target 3 times long and 3 times short a certain digital asset. Compared with the contract, it has the characteristics of simple operation, never liquidation, no margin, and higher unilateral market returns. BiKi leveraged ETF management fee is 0.1%. [2020/10/16] Remarks: Zero-knowledge proofs are used for data storage, optimization in the C2 stage, and zk-SNARKs are used in the second stage of replication proofs; zk-SNARKs (zero-knowledge proofs) also have many algorithms, and there is a The algorithm is called Bellman (Bellman in English). Note: zk-SNARKs are an innovative form of zero-knowledge cryptography, the acronym zk-SNARK stands for "Zero-Knowledge Succinct Non-Interactive Argument of Knowledge" and refers to a proof construction. Characters (participants) Miners Major mining machine manufacturers, Filecoin big miners all over the world. Retail investors cannot participate, or when you can participate, you are not a retail investor, but a big miner. Because IDC site, operation and maintenance, electricity, network fees, hardware costs, software technology and other factors each require corresponding technology and capital. This is not a battlefield for retail investors. The official participation conditions are: "You are the top 100 miners in the world, or you are the top 50 miners in your region, you are eligible to receive rewards." Zhong Gengfa, Founder and CEO of ChainUP: Filecoin is one of the most promising projects this year: On June 22, 2020, "Interstellar Hitchhiker's Guide" was hosted by Jinse Finance, hosted by Node Consulting,, and co-sponsored by Interstellar Agent and Mac Storage. ——IPFS Technology and Application Research Forum" kicked off in Shenzhen. Zhong Gengfa, founder and CEO of ChainUP, pointed out in a roundtable forum themed "Breakthrough and Opportunities of IPFS" that Filecoin is a decentralized network storage infrastructure built on the IPFS protocol. The development and application landing are very valuable. Filecoin transfers the control of data from the centralized system to the individual users, and most of the value generated by the data will be attributed to the users. Filecoin's early incentives for valid data will allow users to use storage services for free, which will accelerate the application of decentralized storage. [2020/6/22] Supply chain The major mining machine manufacturers are actively preparing for the war, and the supply chain system is running at full capacity. Computer hardware includes motherboards, graphics cards, CPUs, hard drives, memory sticks, network cards, chassis, power supplies, etc. Almost the entire industry chain of electronic hardware has enjoyed dividends, which has stimulated my country's electronic manufacturing industry to a certain extent. This is not an exaggeration, especially in the IDC computer room. The IDC business, which is already relatively saturated today, has also received orders from Filecoin mining machine manufacturers. Therefore, Filecoin miners are currently Party A in many business lines. Because the storage server is originally a high-end computer, the supply chain involved is wider, which is fundamentally different from the Bitcoin mining machine that can only do the hash algorithm. Note: Display manufacturers in the electronic hardware supply chain system are no longer included in this supply chain bonus. (This sentence is actually a joke, because this high-end computer does not need several monitors) Location North America, South America, Africa, Asia, Europe, Oceania and other six continents, except Antarctica. Remarks: The weather in Antarctica is relatively bad, and there is no suitable network facilities and computing equipment to participate. Filecoin officially decided to abandon Antarctica after careful consideration. Event Quantity and distribution There are 4 million Filecoins in the world, each of the six continents is a local area, and there are 500,000 in a region, 50*6=3 million. Then the global reward pool is 1 million pieces. 300+100=4 million pieces are the rewards for all big miners testing. Detailed Explanation of the Reward Pool The following is a comparison table between the total amount of storage and the unlocking of rewards: Each miner in the reward pool of each region of the global 1 million reward pool has two rewards. The first reward comes from his own region and the second reward comes from the world . The ratio of rewards allocated to individual miners in the global reward pool is: miner storage capacity/network storage capacity of the top 100 miners. The reward ratio for a single miner in the regional reward pool: the storage capacity of the miner/the network storage capacity of the top 50 miners. For example, suppose a big miner has sealed storage of 1PB. He is in Asia. The total storage capacity of the top 50 in Asia is assumed to be 5PB. He occupies 1/5 (that is, 20%) of the total storage capacity of the top 50 in the region, 250K *20%=50K Filecoin. This is his regional reward. Then, if the total amount of global storage is 20PB, that is to say, 200K is unlocked, because the threshold of 10PB has been reached, but the threshold of 25PB has not been reached. If he accounts for 1/20 of the world's top 100 storage capacity, (that is, 5%), 200K*5%=10K Filecoin. The above formula is combined into: 250K*20%+200K*5%=60K Filecoin. However, in this example, the miner's 60K Filecoin is not obtained immediately after the main network goes online, but is released linearly. How can it be released linearly? All rewards obtained by the current space race will be released linearly 6 months after the launch of the main network. If all storage is completed, the daily release is 4 million / 180 days = 22222.22. In addition, an additional 100,000 reward coins have been added to the official test rewards, which are used to reward the top 20 miners in the entire network for block packaging. These 20 miners will share 100,000 reward coins, with an average of 5,000 coins per miner. Will the rewards of the big miner test be distributed to customers who have purchased computing power? According to different mining machine manufacturers, there may be different distribution plans, which belong to the miners' own decision. Remarks: Even if the coins are obtained, it is difficult to get them into the hands of customers. It does not mean that the miners themselves greedy the coins. The main reason is that the mortgage mechanism has not been fully determined, and the rewards obtained by the big miners for testing the miners are part of the source of the mortgage coins. Of course, it should not be enough to rely on the rewards of the big miners’ tests to mortgage all mining machines. There is a high probability that more mortgage coins will come from the secondary market. Key parameter: Pledge rate The pledge rate refers to how much Fil the miner should pledge for a certain amount of storage in order to continue "mining". For example, it is very important to pledge 100 Fil or 10 Fil for 1T. Obviously, the latter is more beneficial to miners because it can be easily realized. The pledge mechanism is equivalent to a lock-up mechanism, which reduces liquidity and increases demand. Push up the currency price. Of course, it is also to protect the security of the stored data. When a miner node is repeatedly disconnected from the network, data is lost, etc., which endangers the data security quota, the deduction of pledged coins is equivalent to a punitive measure. The amount of pledge in the currently published code = 20-day expected income of the sector + 30% of the token circulation * the proportion of the sector in the entire network (according to the income of the current block height and the computing power of the entire network at the current block height and circulation) The space race’s pledged currency will come out of the official faucet. To receive the pledged currency from the faucet, the miner must use the Github account for more than 48 hours for identity verification. Each account can request 100 pledges from the faucet at one time. currency. The Filecoin faucet is a website where the project party obtains virtual FIL for free from the Filecoin faucet for the convenience of miners participating in the test during the testnet period. Using these FILs allows an initial test of market dynamics without requiring miners to pay any actual funds. Remarks: The faucet means the place where the water comes out, and here it means the place where the coins come out, which is the official Filecoin. Historical allusion: Bitcoin developer Gavin Andresen once bought 10,000 bitcoins for $50 and created a website called "Bitcoin Faucet". points) to promote Bitcoin.
