SoFa-Network (Wormhole Network) is an internet foundational communication infrastructure that integrates network communication protocols, blockchain ledgers, and application layer SDKs. SoFa-Network builds a dynamic, multi-protocol supporting MPN network (Multi-p2p-Network) through its self-developed Multi-p2p-Protocol. It signs and records the data packet exchanges between network nodes via Proof of Packet transmission proof. It quantitatively tracks and settles value transfers among nodes in the network using blockchain technology. Rich SDKs are provided on top of the MPN to support various application developments and practical uses based on SoFa-Network.
