【Project Introduction】
Filecoin is a decentralized storage network that transforms cloud storage into an algorithm market .
Miners - obtain FIL by providing data storage and retrieval
Clients- allow miners to provide storage, distribution and retrieval data services by paying FIL
[Project progress: Testnet phase2 ]
test version:
-
lotus v0.4.0 (The network has been reset)
Test objectives:
-
Four implementations including lotus and go-filecoin complete interoperability
-
Security audit of network and code
-
Hardware configuration/proof structure/economic structure
-
Filecoin test reward program (expected 3 weeks)
project progress:
-
The testnet resets on time and has successfully replaced the previous version
[Hot Spots of Last Week]
-
The biggest thing last week was the official reset of the Filecoin testnet on June 19, and many teams started sprinting. However, this time the Force Zone is only proceeding with its own global partner program and Filecoin test reward program.
-
On June 16, the first Filecoin Virtual Conference was officially held, which was an opportunity to communicate with core developers and ecological developers.
-
On June 18th, following the Filecoin Virtual Conference, the official IPFS community online conference was held.
-
On June 18th, Juan announced Filecoin Ignite and HackFS in Slack, the two events rewarded a total of 400W FIL and 25W US dollars.

-
On June 21st, Hu Feitong updated his article to explain in detail why there is a hashrate war every time the testnet is opened. Those who are interested may wish to read it~
"Why does the Filecoin test have to grab the hashrate ranking? 》
[Progress of testnet last week]
1) After running the first version of the second phase of the testnet for one month, the network was reset at 8 AM on Friday (19th).
2) Test network operation status:
The second phase of the test network has been officially launched, and it has been running for exactly one month. The network has continued to operate, with fewer new problems this week, and the overall operation is stable.

-
The first version of the network was basically stable, with a total computing power of about 8 PiB. But at the same time, some problems with proof and computing power retention were exposed. The problems were basically fixed in the reset version.
-
After the network reset, the system has been running for more than two days, and the number of active miners is about 4,000. At present, the system has stable block production:
-
Last week, the block height was close to 8000, and the effective computing power of the entire network was close to 2.25 PiB, indicating that many new miners have gone all out and the computing power has grown rapidly
-
Last week, the block reward was around 18.295; the block reward started to increase from 1.8847 FIL, and the entire network completed the baseline accumulation goal of computing power at a height of 4,222. The reward reached about 18.30 FIL, and then decreased proportionally.
-
Block generation is relatively stable. The average block interval is about 25s, and there are few empty block rounds; the average number of blocks in each round remains at about 3, which is a relatively good situation since the test network.
-
The average number of messages last week was close to 25, indicating that the network was reset and miners were relatively active.
-
The size of the message last week exceeded 1000 bytes. The main reason was that there were many copies of the proof of message and the average message length was relatively large.
-
3) Main issues:
-
Panic phenomenon still occurs from time to time
-
Memory exception problem
[Development progress last week]
-
Code additions and bug fixes:
-
Some minor enhancements: increase sector health check, increase the function of sending signed messages
-
Improve the calculation method and verification of Gas-[in progress]
-
Update of each sub-module: sector-storage, storage-fsm, go-fil-markets
-
Support for more refined control of the transaction process: such as support for transaction termination, transaction rejection, etc.
-
Improve the performance of proof and chain verification (reducing duplication of work through cache verification results)
-
Documentation update
-
Enhanced search market: searchable on the whole network
-
Storage-miner robustness increase: error handling, perfect state machine; automatic restart after a problem
-
-
Design and certification update:
-
Gas calculation related issues-under discussion
-
Parallel calculation of WindowPoSt circuit in the proof
-
