According to the draft filing to the Hong Kong Stock Exchange, ZhongAn Technology, a wholly owned subsidiary of ZhongAn Insurance, has developed a blockchain protocol called Ann-chain, which serves as its foundation for building applications. A separate platform, called Ann-router, is further described as a blockchain network component "intended to link isomorphic and heterogeneous blockchains." Formed to focus on research and development of financial technology, ZhongAn Technology launched a series blockchain applications last year designed for distributed data storage. The latest, Ti-Packet, launched in May 2017 and described as a blockchain-based signing system, appears to have been adopted in a use case aimed at tracking chicken farming on a blockchain.
