According to Odaily, the Bitcoin Virtual Machine (BVM) team launched a zero-knowledge proof service, BitZK, last week. The service aims to enhance Bitcoin's scalability. It allows users to create rollups and migrate applications from Ethereum to Bitcoin. BVM developer @bird2836 stated that this is the first Bitcoin ZK-rollup on the mainnet. The BitZK service charges a minimum of $99 per month. Early users of the service include RWA Chain, POWD3R Blockchain, and Octopus Bridge.
