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).

When will the big miner test start?
August 25th
It is officially announced that the space test will officially start at 6 am on August 25th, Beijing time. The top 100 miners in the world and the top 50 miners in each continent will receive Filecoin rewards according to their storage capacity during the competition and the network. Once the race starts, progress can be tracked at spacerace.filecoin.io.
When does it end?
The test cycle of the big miners is 21 days, or three weeks.
space race eligibility
Participating miners must respond to storage and retrieval transaction requests from order bots and maintain 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.
Order acceptance rate problem
The storage order deal tested by the big miners 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. Without a VPN, it is difficult to receive deals.
bandwidth problem
The order is only a matter of response 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 orders are mainly based on archive storage. The encryption and decryption process is not very friendly to hot storage. A video is 1G, upload encryption, sector sealing, zk-SNARKs Bellman and other processes will be slower. 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.
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 an algorithm called Bellman (English is Bellman).

character (participant)
miners
Major mining machine manufacturers, Filecoin big miners all over the world.
Retail investors cannot participate or in other words, 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.
supply chain
supply chain
The major mining machine manufacturers are actively preparing for the battle during this period, 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 for 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 the first party 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.

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 Filecoins in a region, 50*6=3 million. Then the global reward pool is 1 million pieces. 300+100=4 million is the reward for all big miners testing.
Detailed reward pool

Reward Pools by Region
Each miner has two rewards, the first reward from his own region, and the second reward from the whole 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 large 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 storage in the world is 20PB, that is, 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 formulas are combined into:
250K*20%+200K*5%=60K Filecoin。
However, in this example, the miner’s 60K Filecoin is not obtained immediately after the mainnet 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 mainnet. 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 schemes, which are decided by the miners themselves.

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. In the event that a miner node has repeatedly disconnected from the network, data is lost, etc. endangering 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 to calculate)
The pledged coins of Space Race will come out from the official faucet. To receive the pledged coins from the faucet, miners must use the Github account for more than 48 hours for identity verification. Each account can ask for 100 pledged coins from the faucet at one time.
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 Events:
Bitcoin developer Gavin Andresen once bought 10,000 bitcoins for $50, and created a website called "Bitcoin Faucet", where everyone came to give away 5BTC (worth 5 cents at the time) to Promote Bitcoin. This is the first time the term "faucet" appears in the blockchain world.
Filecoin faucet refers to the website where the project party obtains virtual Fil from the Filecoin faucet (https://faucet.glif.io/) for free for the convenience of participating miners. Using these fils can conduct preliminary tests on market dynamics without miners Pay actual money.
