ClassZZ itself is a PoW public chain, with a public token called CZZ. Since its stable operation in 2019, it has attracted a certain amount of computing power to maintain network security. ClassZZ community values decentralization above all else, and CZZ tokens are also a "three no products" without private placement, pre excavation, and project parties.As a public chain, one of the core functions of ClassZZ is to support the TeWaka protocol developed by our community. This protocol is fully open source and decentralized, allowing for arbitrary switching of raw currency between the main networks supported by the protocol, making it a "cross-border ship" in the blockchain world. Compared to mainstream cross chain protocols in the market, TeWaka's main innovation and advantage is that it truly solves the "impossible triangle" in the cross chain field, which does not require the pledge of original currency, while supporting most public chains, and completely decentralized....
