【Project Introduction】
Filecoin is a decentralized storage network that transforms cloud storage into an algorithmic market .
Miners obtain Filecoin (FIL) by providing data storage and retrieval. On the contrary, customers pay for the miners to provide storage, distribution and retrieval of data.
At present, the problem of centralization exposure is getting bigger, IPFS projects are gradually increasing, and the demand for the data storage market is also gradually increasing. This means that Filecoin, as an incentive layer, has become a market, and it is an urgent need to escort IPFS.
【project progress】
Test version (run simultaneously):
-
Testnet / 2
-
InteropNet Staging （（Testnet / 3）
Test objectives :
-
Implement interoperability testing (lotus and go-filecoin)
Project progress :
The first phase of the testnet is one week away, and it will end soon.
Testnet/3 InteropNet Staging is currently undergoing major changes, and it will take a while to replace Testnet/2. The Phase II date is approaching, and the development and testing pressure of Testnet/3 is relatively high.
[Hot Spots of Last Week]
-
On April 7th, Filecoin's official browser Filscan (filscan.io) was greatly updated, and the Chinese version can be switched to use, and the content is updated to Testnet/3 test data. "Miner Sharing | Chinese version of Filscan, the official Filecoin browser, is online, you can check Testnet/3"
-
On April 8, Filecoin's official website released an update, and now the last development incentive plan is opened, and the deadline is April 15. "The Force District Regained the Official Developer Incentive Program of Filecoin-Filecoin Wallet"
-
On the afternoon of April 9, the official official account updated the graphics and texts (Slack synchronization), which mainly pointed out that the miners' testing needs to change the direction-from testing their own algorithms and performance to how to effectively store them for real customers.
[Progress of testnet last week]
1) Last week, the official release of a number of important news about the Filecoin test, especially the big miner plan and official statement, all hint at the important role of cluster mining pools in the ecology (regardless of the initial or future development)
2) Testnet/2 operation status:
-
Stable operation for 9 weeks, Testnet/3 will replace Testnet/2 soon, but the specific time depends on the stability of Testnet/3
-
The block height reached 171,350, the block production was normal, and the computing power was 4.497 PiB. The computing power last week was 300T less than the previous week. Maybe because Testnet Phase II is approaching, many miners are preparing for the second phase of testing
-
The current block production of the system is basically normal, and the average number of blocks produced in each round is relatively stable, which is the same as the previous week, at about 2.4. With the current miners withdrawing gradually, it is relatively normal
-
The average block time is 45 seconds, normal
3) The latest situation of Testnet/3 (as of 16:30), due to multiple resets of the network, no statistics are made here
Screenshot of the official browser Filscan
4) InteropNet operating status
-
At present, InteropNet is still in the debugging stage. After many resets, the last reset was carried out last Tuesday (April 7). The initial network operation was very good. A few days later, there were some problems with block production and computing power growth, but the network Still running
-
The biggest progress this time is to solve the problem of compatibility between some Lotus and go-filecoin at the protocol level, and it can currently run on the same network at the same time.
-
Filecoin web browser filscan.io moved from Testnet/2 to Interopnet
-
The main problems that existed in the previous week still exist (the main development effort last week was on the implementation of functions and compatibility with Spec):
-
Block verification efficiency is low, resulting in slower block generation
-
Message verification takes too much time
-
Block synchronization efficiency is low
-
Memory overflow may occur during block verification
-
-
The network is currently in an unstable state, and most miners cannot produce blocks
[Development progress last week]
-
Testnet/3 development continues
-
Realization of offline storage market transactions, and provide tools for data verification and verification; the improvement of Deal information and related state machines to support the completion of transactions
-
Complete the Sealing State Machine (FSM) according to the definition of each stage of Seal in the Spec; and separate the sealing related code into the new Sealing package
-
Complete documentation: Explain the entire storage architecture of the sector, and indicate the relationship between APIs and modules
-
Use WndowedPoSt and WinningPost and improve the code
-
Use independent beacon and drand packages for random number processing
-
Improvement of chain verification mechanism (in progress)
-
-
Spec (detailed design) and certification system
-
According to the test, the performance is comparable to v24
-
The proof of PoSt is now changed to: WindowedPoSt and WinningPoSt; replacing the previous FallbackPoSt and ElectionPoSt
-
Network tax: Every message has to pay a part of the network fee. This part of the fee will not be used as a transaction fee to the miners, but will be directly destroyed. Therefore, this will cause the total amount to continue to decline
-
The economic model may be released this week, mainly at the basic framework and algorithm level, and specific parameters may still be adjusted
-
Some behaviors in the mining cycle may be further refined and optimized
-
Spec has not been updated, but it is likely to bring some changes in the future, including:
-
The v25 public parameter was released to prove that the system was upgraded again,
-
rust-fil-proofs code structure adjustment, stronger modularization; perfect unit test
-
Improve the efficiency of bls hash verification
-
Filecoin Weekly Report is originally produced by IPFS Force Zone
【IPFS Force Zone】
Values: value building and sharing glory
Headquartered in Shanghai, it gathers many technical experts and enthusiasts based on distributed network & storage to deeply cultivate the business ecology and community development based on IPFS.
[The Force Open Day]
It is held every Tuesday and gathers many technical experts and IPFS enthusiasts. Through continuous output of comprehensive, detailed and high-quality IPFS consulting and technical support, the enthusiasts in the ecology are transformed into IPFS supporters and participants, and the IPFS ecology is built together. healthy growth.
