SoFa-Network (wormhole network) is an Internet underlying communication infrastructure that integrates network communication protocols, blockchain ledgers and application layer SDKs. SoFa-Network builds a dynamic multi-protocol MPN network (Multi-p2p-Network) through the self-developed Multi-p2p-Protocol, and signs the data packet transmission and exchange between network nodes through Proof of Packet packet transmission proof And bookkeeping, quantitative statistics and settlement of the value transfer between nodes in the network through the blockchain. And provide a rich SDK on the basis of MPN to support the development and implementation of various applications based on SoFa-Network.
