Design and Implementation of Digital Transaction System Based on Blockchain Environment

In recent years, block chain has gradually become a hot spot of technological innovation, and the common operation of bitcoin wallets can also leak some user information, which has been exploited in the past. Combining different outputs into a single transaction input by wallets is a common form of privacy leakage. This article proposes a new type of distributed, decentralized, and trustless technical solution. Firstly, the design and implementation of the blockchain are studied from a technical perspective. Then, the security of the blockchain is analyzed from both the blockchain itself and the application. Finally, the blockchain security system and traditional centralized security system are compared from the perspective of security architecture. This article introduces a new distributed data storage technology, which has led to changes in system and program design concepts, and may subvert the current organization model of business society.
