At the 2021 7th Blockchain Global Summit hosted by Wanxiang Blockchain Lab, Polkadot founder Gavin Wood said , I am very confident that Parachain will start to achieve technical feasibility in December, and a complete code audit has been completed. In addition, Gavin Wood also shared the status of Substrate and Polkadot. The second bridge audit is in progress. In addition, a bridge from the test network Rococo to the bridge test network Wococo will be deployed to test the feasibility.
