Problems solved by technology

[0004] The above smart contract consensus method based on the POW mechanism is completely decentralized, and nodes can enter and exit freely, but all nodes in the blockchain network need to verify the correctness of the new block, occupying most of the computing power of the entire network, thereby reducing The computing power of the entire network

Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] The method involved in the embodiment of the present invention can be applied to a block chain network, which is essentially a decentralized distributed ledger database, and the block chain itself is a series of data generated by using cryptographic technology. Data block, each block contains information for valid confirmation of multiple b...

Abstract

The invention provides a block chain consensus method based on a DPOS and nodes. The method comprises the following steps that a transaction node generates a transaction request of executing an intelligent contract and broadcasts the transaction request to a block chain network; an accounting node receives the transaction request, then executes the intelligent contract according to the transaction request, stores a generated contract execution result and a transaction request in a newly-generated block and broadcasts the block to the block chain network; and an agent node receives the block, then executes the intelligent contract according to the transaction request and verifies the contract execution result. By using the technical scheme provided in the invention, a common node does not need to verify the contract execution result so that a calculating capability of a whole network can be effectively increased.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a DPOS-based block chain consensus method and nodes. Background technique [0002] Blockchain (Blockchain) is a new decentralized distributed accounting system that has gradually emerged with the increasing popularity of digital cryptocurrencies such as Bitcoin. The nodes in the system do not need to trust each other. Each node jointly maintains a ledger through a unified consensus mechanism, and each node has a complete data record. The transactions of each block in the blockchain are connected together through cryptographic algorithms, making the entire ledger open, transparent, traceable, and tamper-proof. [0003] Smart contracts are an important feature of the blockchain, which can make the blockchain more intelligent. At present, there are four main types of consensus mechanisms in blockchain: Proof of Work (POW) mechanism, Proof of Stake (POS) mechanism, Del...
