They call themselves a BTC layer 2 with smart contracts and all types of abilities. But reading their lightpaper made me feel like they're just a regular smart contract chain with a BTC bridge. Basically you can send your BTC to their multi-sig bridge address which gives you XBTC, which then allows you to do stuff on their chain. They often compare their chain to Polkadot. It's EVM and WASM compatible, etc. Given that Polkadot and Ethereum also have BTC bridges, ChainX feels like an inferior version. It feels more like a multichain solution rather than a BTC layer 2. I don't think they finalize any processed data on the Bitcoin chain.
Their second focus is an app that "does everything'. It has a chat and a wallet and some other stuff. I've installed it and it wasn't fun or easy to use. I also don't think that there's anything on-chain about their messaging for example. But couldn't find detailed infos on it. Show Less
