Parity releases Polkadot version 0.9.3, which is a higher priority release. Kusama and Polkadot nodes should upgrade as soon as possible! https://github.com/paritytech/polkadot/releases/tag/v0.9.3
Dr. Gavin Wood attended the Consensus 2021 conference, shared the place of EVM in blockchain development and argued that the future of smart contracts belongs to Wasm!
The Polkadot network has been running for a year now! At this time last year, Polka started the Genesis block, then upgraded from the PoA network to the PoS network, turned on the governance function, removed the sudo module, then turned on the transfer function, and renamed the denominations… Next, let’s look forward to the parallel chain!
On Monday, several nodes failed with a “stored root mismatch” error due to different compiler versions for building the local runtime and the Wasm runtime on the chain. The problem was not caused by a bug in the rust compiler. Check out this error analysis: https://polkadot.network/a-polkadot-postmortem-24-05-2021/
Polkadot has posted a review of all the videos on Polkadot Decoded on YouTube, check it out here: https://www.youtube.com/playlist?list=PLOyWqupZ-WGuAB8z_PkZD6f-IA6CUONFb
Polkadot’s Referendum #23 to add an attorney as a new identity registrar did not pass the ballot! https://polkadot.polkassembly.io/referendum/23
Referendum #24 to increase the size of the Wasm heap page is now on the ballot. The original sponsor asked that the proposal be rejected. See details here: https://polkadot.polkassembly.io/referendum/24
The Plasm team, together with Parity, submitted a proposal to implement Brave Browser THEMIS, a protocol for decentralizing the Brave Ads infrastructure, using the Substrate and Polkadot ecosystems. All proposals can be found on GitHub. https://brave.com/themis-rfcc-wrap-up/
Polkadot-JS is now available on IPFS, and the URL https://dotapps.io will always lead to the latest version of Polkadot! If you are interested in helping to promote decentralization, you can also fix a copy of Polkadot-JS on IPFS. Check out the introduction here: https://github.com/polkadot-js/apps#ipfs
You can also run Polkadot-JS fully locally using Electron. Instructions are here: https://github.com/polkadot-js/apps/blob/master/packages/apps-electron/README.md
WinKrypto released a motion seeking feedback from the Polkadot Council, which provides Polkadot news mainly to the Asia-Pacific region! https://polkadot.polkassembly.io/post/408
The Kusama Council has voted to approve motion 299 (upgrade Kusama’s runtime to 9030) and put it to a referendum, after which the Technical Committee accelerated the vote, which ended this Friday! Kusama’s runtime has now been upgraded to v9030, which adds some necessary changes to the parallel chain. After this update, Shell Parallel Chain is running stable! Look forward to the Statemine upgrade! https://kusama.polkassembly.io/referendum/113
Expect to see more differences in pledge rewards in the near future, as those verifiers who choose to connect to a parallel chain typically receive more era points. The choice of which verifier connects to the parallel chain is random and the rewards should balance out over time.
A second Kusama Town Hall will be held on May 27 at 14:30 CET to discuss Encointer’s proposal for a parallel chain of public interest identities. More on Encointer’s motion here: https://kusama.polkassembly.io/post/610
