On May 31st, at the MAPO Seoul Hackathon, the full-chain interoperability infrastructure MAP Protocol announced that it will soon launch the MRC20 full-chain currency issuance protocol. Different from the current ERC20/TRC20/BRC20 token issuance protocol, the MRC20 protocol can cover the entire chain and realize data exchange between tokens of each chain. The protocol will adopt the MAP Protocol unprivileged role data cross-chain verification system to achieve credible token cross-chain data ledger alignment. MAP Protocol said that the protocol is more friendly to developers and users: developers can issue and create tokens very easily on the low-code platform, and the data of tokens on each chain can be exchanged, while the source chain and target chain The tokens on the platform adopt the destruction/increasing mode, and no cross-chain bridge is needed anymore; in addition, cross-chain Gas Fee payment is provided through butternetwork.io, and users are completely unaware of the existence of the chain when using tokens.
