Filecoin Weekly-Issue 55: Several major events in the Force Zone. Which are you involved in?

 

Co-edited by Steven Li and Iris

【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

Test objectives:

• Security audit of network and code

• Hardware configuration/proof structure/economic structure

• Filecoin test reward program (expected 3 weeks)

project progress:

• The test reward program starts on July 20

 

[Hot Spots of Last Week]

• The biggest thing last week was the Babbitt Blockchain International Week in early July. The Force District was invited to participate in the conference sharing, and held its own Force Open Day event in Dream Town on the 6th.

• On July 4th, the Force District supported the college entrance examination and opened the Filecoin knowledge answering activity. Today is the last day of answering the questions. Please take the time to answer the questions~The answer is over at 24:00 tonight, and the lottery will be opened.

• On July 2nd, Xin Ge, CTO of the Force District, was invited by Mars Cloud Mine to conduct an online AMA at 8 pm to interpret the 4 million FIL test reward plan.

• On June 30, Filecoin's official blog was updated, announcing the list of the third developer incentive plan, and updated the fourth and the goals of the Big Miner Test Award program.

[Progress of testnet last week]

1) The test network synchronization problem has been improved

2) Test network operation status:

• After the network reset, the system runs for more than 15 days, the number of active miners remains above 4000, and the system produces stable blocks

  • Last week, the block height exceeded 52,800, the effective computing power of the entire network reached 16.579 PiB, a weekly increase of more than 7 PiB (9.18 PiB in the previous week), and an average daily increase of more than 1.0 PiB, continuing the growth trend of the previous week

  • Last week’s block rewards ranged from 18.26FIL to 18.22FIL in the previous week, and the rewards were slowly decreasing exponentially according to the rules, in line with expectations

  • 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 2.55, which has decreased compared with the previous week. The main reason is the increase in the proportion of computing power occupied by large miners

  • The average number of messages last week was about 35, indicating that many miners have recently participated in the test and the network is relatively active

  • The size of the message last week exceeded 926 bytes, which was basically the same as the previous week. It is mainly used to prove the message.

3) Main issues:

• WindowedPoSt still has the problem of not needing to prove

• WinningPost verification is too slow

• When the disk space is insufficient, the sector status is abnormal

• heaviestLk deadlock problem-under repair

• Predictable election issues-design issues (non-implementation issues): repair in progress, slightly more complicated

 

[Development progress last week]

• Code additions and bug fixes:

  • Update mining logic

  • Fix bitfield related issues and improve the resolution speed

  • Update market related codes

  • Gas calculation code test and update

  • Realize transaction expiration and related penalties

  • Optimize the libp2p link and synchronize with the optimization chain

  • Improve the verification speed of WinningPost

  • Some configurations are changed from constants to variables for easy configuration

  • Increase the flexibility of users to retrieve transactions

  • Sector upgrade support

• Design and certification update:

  • Improve the I/O mode of phase2 to limit memory usage

  • Enhance the test of the proof section

  • Some security improvements: security audits have found many problems

  • Improvements to the block right election-basically completed
