Polkadot's one-week observation is a summary of what happened to Polkadot's entire ecology last week, and we will also share some of our observations on these events in the form of vernacular. This article is intended to provide information and opinions, and does not endorse any project. Any project mentioned is not for investment recommendation, but for information display only.

Observation and Viewpoint

The epidemic in the United States has rebounded rapidly. In less than a month, the United States has become a high-risk area that is almost completely red. In view of this, the expectation of raising interest rates in the old United States has to be postponed with a high probability, and the entire Crypto market has also ushered in a good performance. . Therefore, we have begun to see a good degree of activity in the Polkadot ecosystem. Polkadot officials have also released three articles in a row to summarize Polkadot’s achievements in the past period of time, and announced the time for the next round of Kusama slot auctions. And became the most noteworthy event last week.

Let’s review the dazzling data of the last round of Kusama slot auction: After 5 rounds of auctions, more than 1,478,800 KSMs were finally locked, accounting for nearly 15% of the total. We seem to have a lot of expectations in the second round. If there is a lot of lock-ups, then the Kusama ecology can be said to have entered the stage of the "flywheel effect".

(The flywheel effect refers to the fact that in order to turn the stationary flywheel, you must use a lot of force at the beginning, and push it repeatedly round and round. Every turn is very laborious, but the efforts of each turn will not be in vain. , the flywheel will spin faster and faster.)

Therefore, once the second round of Kusama slot auction is successfully completed, both for Kusama and Polkadot, it means that the "flywheel" has been successfully started, and what we have to do is to pay attention to how fast it can turn, and What is the next "flywheel" that may be driven? Only by seeing these changes can an ecological participant better grasp the next opportunity.

But as the official summed up: "Overall, the network is running smoothly. Although the average number of peers and network speed seem to have no errors in the entire network, there are still some abnormal nodes that are over-connected and need to take on higher-level responsibilities. load."

Polkadot Dynamics

Also, a note worth noting at the end of this article: The only problem is the infrequent block finality stalls encountered by the network. Luckily these pauses were caught by the failsafe, so it didn't do much damage and wasn't a big deal. With the opening of a new round of Kusama parachain slot auctions, allowing more parachains to enter Kusama is the goal of the next stage. To speed up the testing on Kusama, the more tests on Kusama, the corresponding functions on Polkadot will be more effective. Come sooner. After this auction is over, the auction will still be suspended to observe the network performance, and then the third round of auction will start.

Finally, as we said at the beginning, a lot of interesting things have happened in the Polkadot ecology, which are explained below. The following is a detailed introduction of the Polkadot ecology news last week, please enjoy.

[Polcato releases Kusama and Parachain Stability Report: There is a network deterministic pause problem, but the overall operation is stable]

• On August 17, in the Kusama and Parachain Stability Report released by Polkadot, it was obtained by combining the four key factors of parachain block stability, approval voting (ApprovalVoting), network connection, and load (CPU and network). Conclusion, currently the network is running smoothly, the only major issue is the occasional finality stalls that the network is experiencing, however as these stalls are caught by failsafes, they haven't done much damage, the root cause is currently being investigated and will be posted in The parachain gives a solution before it starts on Polkadot.

• After the first 5 parachain auctions, researchers monitored the stability of the Kusama network. At this point, there are 6 parachains on the network. Polkadot focuses on 4 key areas:

• Internet connection

• Candidate stability

Approval Vote Statistics

Internet connection

load condition

• Researchers sampled metrics from opt-in validators to collect information on Prometheus and Grafana: https://mp.weixin.qq.com/s/l_H7UzlVoOs9L9-vDx1bog

• [The second round of the Kusama Parachain Slot Auction on Polkadot Pioneer Network will start at 12:00 GMT (20:00 Beijing time) on September 1st, so that members of the Kusama community will have enough time to bid for their auction and participate in the public auction. raise】

• Polkadot observes the performance and stability of the six parachains currently on Kusama through the report published here. Parachain block production, approval, and finalization are generally stable, with occasional events related to temporary pauses in block finalization. The cause of these incidents is under investigation, and Polkadot will come up with solutions to resolve the issue after the next five Kusama auctions and before the Polkadot auction. The core development team at Parity Technologies doesn’t think the next five parachains on Kusama will exacerbate this problem — Kusama is relatively chaotic, and access to more real-world data means smoother future Polkadot launches. Therefore, Parity recommends to the Kusama Council that the next parachain auction start on the following schedule:

The auction consists of an initial bidding period of two days followed by a closing period of five days (in the same manner as the previous five auctions)

According to the latest Polkadot weekly report released by PolkaWorld, important events this week include:

Five auctions were held over five weeks, with a pause to assess overall network performance, before a third batch of five auctions began on a similar schedule

• [Polkadot Weekly: Polkadot publishes three articles in a row, opening the second round of Kusama auction! 】

• According to the latest Polkadot weekly report released by PolkaWorld, important events this week include:

• Jonas Gehrlein, a research scientist at the Web3 Foundation, released an overview report on Kusama's first round of parachain slot auctions. PolkaWorld summarizes the important points as follows:

• Through the first 5 auctions, the feasibility of the candle auction mechanism is proved, which ensures the efficiency and fairness of the results;

• The process of slot auction is a decentralized one, and there is no profit-making entity, so it will not create so-called "income";

• In the future, several projects will jointly bid for a lease period;

big ecological news

At present, most project parties need to first realize the launch stage, and winning the auction is more important than minimizing the bidding price! But as these networks reach the expansion phase, flexible bidding, i.e. bidding for projects to minimize bids, is an important factor in effectively maintaining parachains;

The scarcity of parachain slots ensures healthy competition in the future and helps to find and screen the most suitable projects. This novel contribution mechanism can improve the overall quality of the ecosystem, providing users with a healthy environment where they can easily support new projects!

Once the final stage is completed, the Moonriver crowdlending rewards will be sent to the crowdlending participants, and the transfer function will be enabled, and decentralized applications and assets will also be able to be deployed on the Moonriver network. As one of the first batch of Kusama parachains to focus on technology, Moonriver and Parity dealt with a large number of compatibility bugs between Kusama during the deployment phase, not only for Moonriver, but also for the benefit of other projects on the ecosystem and security. For Kusama, it is very important to find and fix these problems, which is one of its purposes as a Polkadot canary network (experimental network). At the same time, it is also expected that Moonbeam can provide a safe, stable and fast deployment reference for the subsequent connected parachains.
