The BTFS protocol has successfully launched its v4.0 mainnet, introducing significant upgrades to enhance network reliability, transparency, and governance. Key improvements include a storage provider-exclusive node solution (BTIP-89), a metadata transparency management mechanism via smart contracts (BTIP-90), and a distributed governance system for community autonomy (BTIP-91). These enhancements aim to optimize the BTFS network's infrastructure, boosting security and scalability, and supporting the development of Web3.0 data storage infrastructure.
