Block chain contract-based fast transaction system

Abstract

The present invention discloses a block chain contract-based fast transaction system. The system comprises a distributed authentication unit, a contract access server and contract nodes, wherein the distributed authentication unit comprises one or more service nodes and a plurality of authentication nodes, and the contract nodes comprise common contract nodes and rapid transaction contract nodes. The implementation method of the system includes the followings steps that: (1) a fast transaction is initialized; (2) a contract layer realizes the fast transaction; and (3) a bottom consensus layer realizes the distributed confirmation of rapid transaction history and writes confirmation results to a block chain. With the block chain contract-based fast transaction system of the invention adopted, rapid support for the transaction is realized, and the influence of the closing time of the block chain, the size of blocks and distributed network transmission on the execution of the transaction can be avoided; the Byzantine fault tolerance of the transaction system is maintained; delay phenomena of an existing block chain transaction mode in transaction spread, a consensus process and a contract execution process can be avoided; the details of the transaction can be hidden and encrypted; and the system has the inherent advantages of distributed block chains.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a contract-based fast transaction system of block chain contracts. Background technique [0002] The existing blockchain-based distributed transaction methods are greatly limited due to the blockchain consensus method, the generation time of the blockchain, the generation time of the block, and the size of the block. The transaction speed based on blockchain is generally at the second level or even above the minute level. In addition, there are the following defects: [0003] 1. There is a delay in the propagation process of a transaction request in a distributed system, and there is an information delay between an initiating node and the information spreading to all other nodes; [0004] 2. There is a time delay in the consensus process: the data update must be written into the ledger after the consensus is completed. This writing is intermittent and updated once every ver...

AI Technical Summary

Problems solved by technology

[0003] 1. There is a delay in the propagation process of a transaction request in a distributed system, and there is an information delay between an initiating node and the information spreading to all other nodes;

[0004] 2. There is a time delay in the consensus process: the data update must be written into the ledger after the consensus is completed. This writing is intermittent and updated once every verification cycle. The user's request for data update must be issued after the update cycle. get the response and return;

[0005] 3. Existing smart contracts are not only affected by the above two points, but also by contract execution delays

[0006] Some existing solutions, such as the Lightning Network and the Bitcoin network, use channels to speed up the processing of transaction requests, but the protocols of the above solutions are either relatively complicated, or use a non-Byzantine fault-tolerant method, which limits their wider application. application
