Embodiment Construction

[0023] In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings show, by way of example, specific embodiments in which the invention can be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Accordingly, the following detailed description is not limiting, and the scope of the invention is defined by the appended claims.

[0024] First of all, let’s explain some terms involved in the present invention. The blockchain can include various nodes, but the present invention is aimed at verification nodes. The nodes, storage nodes, and block generation nodes mentioned in this article all refer to verification nodes, and all The correspon...

Abstract

The invention discloses a blockchain consensus method. The method comprises the following steps: a first verification node obtains at least two hash values; based on the at least two hash values, thefirst verification node determines data blocks corresponding to the at least two hash values in a current main data file stored in the first verification node; the first verification node performs hash operation on the data blocks to determine a current root hash value corresponding to the current main data file; and the first verification node and the remaining verification nodes respectively determine the correctness of the current root hash value. By adoption of the blockchain consensus method, a large amount of CPU calculation does not need to be consumed, and meanwhile the network participants can be stimulated in a reward and punishment mode to provide security guarantee for blockchain data.

Description

technical field [0001] The present invention relates to blockchain technology, in particular to a blockchain consensus method. Background technique [0002] Blockchain is a new type of distributed system that combines computer technologies such as distributed data storage, point-to-point transmission, encryption algorithm, and consensus mechanism. It maintains a set of distributed ledgers jointly by multiple participating nodes, realizing data The characteristics of tamper-proof and traceable information create a secure distributed trust system. [0003] Maintaining a public ledger in the blockchain requires a powerful, efficient and secure consensus algorithm. A safe and stable consensus algorithm is the fundamental guarantee for consistent data in the blockchain. POW is used in the Bitcoin network, also known as the proof-of-work algorithm. Since this algorithm consumes a lot of computing resources and causes a great waste of electricity, people continue to propose vario...
