Babbitt reported on the 18th, at the Polkadot China trip Beijing station hosted by Randam Capital, Dr. Gavin Wood, founder of Polkadot, shared the latest developments of Polkadot. The first point is trading weights: most applications don't require smart contracts, as long as their business logic can operate. So we can make predictions and flexibly set weight tags for the trading interface to ensure accurate use of the resources of the block. If your trading interface is more complex, you can implement the weighting logic yourself. The second point is transaction scalability: you can add arbitrary logic to the chain trading and create your own extensions. The extension is present in the module and the state of the module can be used. The third point is the crowdfunding parallel chain: you can let the Polkadot community fund your parallel chain, allowing unlicensed donations, and you can use these donations and auctions to bid on parallel chains. Successfully bidding tokens are locked into parallel chains, which can be identified by Merkel root calculated from all the information. These contributions will be returned after the parallel chain, so there is no risk to the donor. The fourth point is "collective", which is a new module on chain governance, which is a plug-and-play component. It is allowed to form interest groups in any member relationship for chain governance. Chain governance can bring about hundreds of millions of capital operations a year, which also increases the value of the entire chain.
