Twitter co-founder and $Block CEO Jack Dorsey has announced the launch of a decentralized peer-to-peer chat application called bitchat, which uses a store-and-forward model and message encryption to provide a decentralized communication experience without the need for the internet. It is currently available for TestFlight testing, and the ultimate goal of the protocol is to build a censorship-resistant communication network that can operate in offline environments. [吴说]
