Ethereum development environment tool Hardhat released v2.6.1 to solve three problems

The Ethereum development environment tool Hardhat has released v2.6.1, which solves three problems:

1. When a user connects to a Hardhat node through websocket, the node has a problem. Now the websocket connection should work normally.

2. debug_traceTransaction can be used for transactions sent from a demo account.

Ethereum JavaScript library Ethers.js is funded by Chainlink community grant

The Ethereum JavaScript library Ethers.js is funded by the Chainlink Community Grant and will be extended to other EVM-based blockchains through auxiliary packages. Chainlink said that adding support for other EVM-based blockchain networks will enable Ethers.js to further simplify the development and deployment of Web3 applications. As part of the funding, Ethers.js will create an auxiliary package dedicated to OKExChain and additionally support Chainlink oracles. In addition, Ethers.js will also create clear guidance documents that allow external blockchains to create their own auxiliary packages, so that Ethers.js can support its EVM chain to facilitate Web3 developers to develop hybrid smart contract applications.

Kusama network

Polkadot advance network Kusama will launch the second round of five parachain slot auctions

The Polkadot Advance Network Kusama Committee will conduct another five parachain slot auctions in the next few weeks, scheduled on September 1, 8, 15, 22, and 29 at 12:00 GMT (Beijing time) 20:00).

Polkadot releases Kusama and parachain stability report: there is a network deterministic stall problem, but the overall operation is stable

On August 17th, in the Kusama and Parachain Stability Report released by Polkadot, the four key factors including the stability of parachain production, approval voting (Approval Voting), network connection and load (CPU and network) were obtained. In conclusion, the current network is running smoothly. The only major problem is the finality stall that the network occasionally encounters. However, since these stalls are captured by the fail-safe device, they have not caused much damage. The root cause is currently under investigation. Parachain will give a solution before launching on Polkadot.
