摘　　要：针对传统的数字资产交易和管理技术需要加入第三方中心交易平台容易带来安全隐患的问题,文中将区块链技术引入到数据库中,构建了一种基于区块链技术的数字资产交易方法。该方法采用了数据区块存储数据实现了分布式存储,采用了非对称加密RSA算法及双SHA256哈希函数实现了数据加密,采用了共识机制去除了第三方管理机构,因此具有较好地安全性和可靠性。经过测试、验证和使用,文中提出的方法效果良好,能够及时发现非法侵入和恶意篡改,具有良好的应用价值与参考意义。Aiming at the security problem that traditional digital asset transaction and management technology needs to introduce third-party central trading platform,this paper proposes a digital asset transaction method based on blockchain technology. The data is stored by the use of the data block to realize the distrubuted storage,the asymmetric encryption RSA algorithm and the dual SHA256 hash function are used to implement data encryption,and the consensus mechanism is adopted to remove the third-party management organization,which all ensure the safety and reliability of the transaction method. After testing,verification and application,the method proposed in this paper works well and can detect illegal intrusion and malicious tampering in time,which has certain application value and reference significance for the similar digital asset transaction technology.
