UNCH (Union Coin) is a main chain developed outside of Bitcoin and Ethereum systems, with multi chain consensus, multi chain parallelism, and multiple hybrid consensus mechanisms. 1 and cross chain atomic operations. 2. Build a high-speed cross chain asset circulation highway.The technology of United Currency (UNCH) has realized the seamless cross chain interoperability between all joint blockchains. Each blockchain constructed using UNCH is also connected to 99.9% of the chains in the coin circle through atomic exchange technology. The future plan for blockchain bridging support is in place, which will create cross chain substitutability across the entire blockchain industry. In addition, with the architecture of UNCH, multiple blockchains can be synchronized and run as a single chain....
