Befy is a pioneering decentralized bridge that enables cross-chain transactions between Bitcoin and Ethereum Virtual Machine (EVM)-compatible networks. Utilizing a Proof of Stake (POS) network, it introduces decentralized bridge nodes. These nodes can be set up by anyone, without needing permission, simplifying the process of becoming a bridge node. The platform is designed for security, efficiency, speed, and cost-effectiveness, enhancing the connectivity between Bitcoin and EVM networks. This innovation opens new possibilities for blockchain interoperability and decentralized finance (DeFi) applications.
