Class ZZ itself is a PoW public chain. As a public chain, one of the core functions of Class ZZ is to support the Te Waka protocol developed by the community to achieve asset cross-chain in a completely decentralized way. Te Waka is a decentralized cross-chain protocol between native tokens of Class ZZ. It will connect ETH with HECO, BSC, OKChain, Polkadot, Tron cross-chain transactions and DeFi ecology. In the future, users can participate in DeFi products such as cross-chain trading, cross-chain mining, cross-chain lending and cross-chain derivatives between them.
