Block chain based consensus and authentication method and device

Abstract

Embodiments of the present invention disclose a block chain based consensus and authentication method, a device, and a computer readable storage media. the block chain based consensus method includesgenerating a transaction block including transaction information based on a transaction associated with a first node of a block chain network; Adding the transaction block to a block chain of the first node without consensus on the transaction block; Sending a consensus message for consensus on a new checkpoint block to a second node of the block chain network, the parent block type of the new checkpoint block being a transaction block, The new checkpoint block including consensus information generated based on consensus results from the second node, and adding the new checkpoint block to theblock chain. The consensus method according to embodiments of the present disclosure can significantly reduce the data transmission load and the consensus complexity due to the need for consensus on all transactions in the system in the current block chain system.

Description

technical field [0001] The present disclosure generally relates to information processing technology, and more specifically, to a blockchain-based consensus and verification method, device, and corresponding computer-readable storage medium. Background technique [0002] Blockchain (Block Chain) technology is based on a decentralized peer-to-peer network, combining cryptography principles and consensus mechanisms to ensure the continuity and continuity of distributed data at each node, and to achieve instant verification, traceability, and tamper-resistant information And other characteristics, thus creating a distributed trust system with privacy, efficiency and security. [0003] The traditional blockchain system collects all the broadcasted transactions in the network and packs them into blocks, and each node verifies and forms a consensus. However, the throughput of the traditional system is limited by many factors: the packaging ability of the nodes, Limitations on net...

Problems solved by technology

[0003] The traditional blockchain system collects all the broadcasted transactions in the network and packs them into blocks, and each node verifies and forms a consensus. However, the throughput of the traditional system is limited by many factors: the packaging ability of the nodes, Limitations on network transmission capacity for a large number of transactions, block size limitations, consensus delays, etc.

The current mainstream blockchain processing method does not make reasonable use of the rich bandwidth and computing resources in the peer-to-peer network, but gathers all transactions to a single point or a single block for processing. The fundamental reason is that the traditional blockchain design only allows There is a main chain in the whole system. Even with technologies such as side chains and Lightning Network, it is still impossible to avoid the single-point performance bottleneck of the main chain.
