Wanchain is a blockchain-based distributed superfinance marketplace. This is the definition that the developers whitepaper suggests. It is noteworthy that this loud name hides a really interesting filling. The Wanchain platform allows you to exchange digital assets between other blockchains. It uses the latest cryptographic theories to build a non-proprietary cross-chain and distributed ledger protocol that records both cross-chain and internal transactions.
