It believes that the application direction of blockchain technology has been clarified and is about to enter a stage of steady advancement. However, there are still some bottlenecks to be solved in terms of blockchain computing and storage to meet the needs of high-frequency applications. (Securities Daily) [2021/7/6 0:29:30]

When the participation rate of the Ethereum 2.0 test network is too low, the withdrawal of giant whales may cause failure

Lior Yaffe, co-founder of Jelurida, said that he discovered a weakness in the Ethereum 2.0 test network. Ethereum 2.0 requires a minimum participation rate of 66%. Participation rates dropping below 66% caused network problems.

If 10% of ETH is pledged and the network participation rate is 75%, reducing the participation rate by 9% only needs to control 0.9% of the ETH in circulation, which can be achieved by large whales and medium exchanges, while Binance, Coinbase, Vitalik, etc. Both institutions and individuals hold more than 0.16% of the total amount of Ethereum. Developer Raul Jordan said that the participation rate is estimated to be around 99%. If the attacker wants to attack, he needs 25,000 verification nodes with a pledge of 33%, which is worth about $100 million, and the attack will cause losses to multiple parties, including the attacker himself.

Filecoin founder: Big miners need to pay attention to Filecoin's basic handling fee

Regarding the recent increase in Filecoin Gas fees, Filecoin founder Juan Bennett said in the Slack community: We need to pay attention to Filecoin's basic handling fees and use the latest message filtering code (0.6.0+). At the same time, miners cannot add some blocks that do not belong there in order to change the basic handling fee rate, otherwise the basic handling fee will increase. And it will cause this week's FIL to be destroyed. All FIL being destroyed will mean that you can't submit messages, and you won't be able to complete the big miner test competition. (Beep News)

On September 8, Filecoin officially released an update announcement on the economic coefficient. The announcement shows: 1. The increase in the initial value of the baseline and the reduction in the growth rate will stimulate economic development more permanently. 2. The 20-day delay in unlocking block rewards will be removed, and the unlocking will begin immediately after mining. 3. The sector fault detection fee and sector termination fee are lowered to reduce the risk of miners’ operation and maintenance. 4. The minimum storage order pledge is lowered, making paid orders more attractive. 5. The sector failure fee is actually low, but due to consideration of the early stage of the network, it will not be raised temporarily.

Further Stress Tests in Week 3 of the Filecoin Space Race

On September 7th, according to official news, the Filecoin space race has entered its third week. This week, the Filecoin network will conduct a further series of stress tests to evaluate the network's overall response to failures and updates. Filecoin official staff Mosh said in slack that especially in the early stage of Filecoin, as a community, it must be highly adaptable and flexible. All representatives of large miners need to be online 24 hours a day, 7 days a week. can be updated quickly.

The specific schedule for this week is as follows:

1. On September 7th (Tuesday in some areas), Filecoin will start updating a small chain to test the overall update speed. It is expected that nodes can be updated to the new chain state in a few hours. This will demonstrate how quickly the network can react to bugs and mainnet attacks. (The window maintenance period will start at 3:00 on September 8th, Beijing time, the Lotus 0.5. at 15:00)

2. If the previous step goes well, a simple version of Drand's entire network shutdown will be triggered on September 9 (Wednesday) to test the network's ability to respond to errors. Drand is a highly resilient and random beacon that can be used to determine whether the Filecoin network can successfully recover from a network suspension.

3. On September 10th (Friday in some areas), the complexity of the upgrade will be tested. The Filecoin network can handle more complex role upgrades. It will also include tools and tools to make future upgrades easier, so as to ensure that the network can be improved in the future. And updating Filecoin roles, given the complexity, there will be a slightly extended update window. In addition, Filecoin officials also stated that they will coordinate the maintenance windows of some trading robots and the above updates, and continue to observe closely to ensure that these important tests will not affect the competition. At the same time, the browser information shows that the entire network storage has reached 133PiB.
