Description
Technical Field
The invention belongs to the technical field of transaction records, and particularly relates to a distributed transaction recording method based on a block chain technology.
Background
The traditional transaction records depend on a third-party mechanism, the transaction process is multiple, the efficiency is low, the time is long, the data of the transaction records are stored in a database of a central mechanism, the central mechanism manages all user account information and transaction history records, the data safety factor is low, and once the database is attacked, the data is difficult to recover; the user only grasps own record and cannot know the transaction records of other users, so that the establishment of a mutual trust market is influenced. There are hidden dangers of transaction safety and privacy protection.
The blockchain, in a narrow sense, is a chain data structure that combines data blocks in a sequential connection manner according to a time sequence, and is a distributed account book that is cryptographically guaranteed to be not falsifiable and not faked. Broadly speaking, the blockchain technique is a completely new distributed infrastructure and computing paradigm that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secure data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data.
In the distributed transaction recording system based on the block chain technology, each node becomes an independent producer and consumer, each main body equally disperses decisions, all transactions are disclosed, transaction nodes can be anonymous, the security of node accounts is guaranteed, a central server is not needed in decentralized management, expensive operation and maintenance expenses are avoided, and the cost is reduced. Safe data sharing, more data, optimized models and better results; and data tracing and tracking are performed, and mutual trust between market main bodies is increased.
In traditional business networks, all participants maintain their own accounts, and duplication and differentiation between these accounts can lead to disputes, longer settlement times, and associated indirect management costs due to the need for intermediaries
