MASS is an open-source PoC (Proof of Capacity) consensus algorithm proposed by top computer scientists at Massachusetts Institute of Technology (MIT). It is the second generation consensus technology after the Bitcoin PoW consensus, successfully solving the problem of high energy consumption in Bitcoin and providing bottom level consensus support for any blockchain. Its technological innovation lies in that each user only needs to contribute a small amount of space to participate in the storage and verification of blockchain data. Based on MASS, a million level space spanning the world will be connected into a super consensus machine, providing public services to safeguard blockchain.The MASS blockchain system is the first public chain to use the MASS consensus engine. MASS cryptocurrency is the value storage of the MASS blockchain system and the value anchor of the MASS consensus engine....
