The TODA protocol enables every ledger-based blockchain to scale to billions of users and handle millions of on-chain transactions per second at a near-zero cost. TODA-T is the next evolution of TCP/IP for value transfer over the communication layer and below the operating system. It is a layer-zero protocol in a decentralized setting. Any Blockchain can run on top of TODA to not only benefit from Security, Efficiency, Confidentiality and Scalability by design but also enabling a P2P atomic swap exchange between any two blockchains without depending on third parties.
