Wanchain is a distributed ledger that allows for cross-chain transactions and the interoperability of multiple chains. Although Wanchain facilitates transactions between blockchains it is also a stand-alone blockchain that runs autonomously. The protocol acts as a distributed ledger that processes and maintains records of cross-chain transactions.Transactions on Wanchain do not only occur between different public blockchains but between private chains as well. As an Ethereum (ETH) fork Wanchain enjoys some of the properties of the Ethereum blockchain. The protocol securely and autonomously processes applications via smart contracts. The use cases for Wanchain include decentralized exchanges (DEXs) lending and borrowing platforms stablecoins crowdfunding multi-currency payments and settlements.The platform is totally decentralized and requires no custodian party to manage or confirm transactions. Unlike other cross-chain systems Wanchain does not rely on a third-party platform to authenticate transactions. The locked account mechanism is used to secure and manage accounts on the network eliminating third-party interferences.
