WDNA public chain is based on the WDNA gene strand. We will make more mature and innovative technical support to implement a variety of DAPPs in smart contract programming on the WDNA public chain. (The common application is known as APP, the APP built on a decentralized platform is called DAPP.) The combination of WDNA products will also continue to be implemented, and real genetic data will be imported into smart contracts to realize the value of them, thus realizing the commercialization of WDNA.
