BitXHub, the cross-chain technology platform of FunChain Technology, is officially open source. In the platform name, Bit stands for data, X stands for security, and Hub stands for relay. From a technical perspective, BitXHub is essentially a secure and efficient cross-chain platform that uses a relay mechanism. It focuses on inter-chain ledger interoperability in heterogeneous alliances and solves the core challenges of transaction capture, transmission, and verification in cross-chain. Independent intellectual property rights. In addition, the FunChain team also proposes a universal cross-chain transmission protocol like TCP / IP: IBTP (Inter-BlockchainTransferProtocol) based on the requirements of inter-chain interoperability. Difficulties in cross-chain transaction mutual authentication caused by different consensus algorithms, ledger structures, and encryption mechanisms.
