Block verification method and device

Abstract

The embodiment of the invention provides a block verification method and device. The method comprises the steps that the identification information, the hash value and the signature information of a block sent by a root node are received; the signature information is verified according to the public key of the root node; if the verification is successful, the corresponding relationship among the identification information, the hash value and the signature information of the block are stored; a block to be queried is acquired from a server node; and the block is verified by comparing whether the hash value carried in the block is consistent with the hash value of a locally stored block. According to the embodiment of the invention, a mobile terminal node receives the identification information, the hash value and the signature information of the block sent by the root node, and stores the corresponding relationship among the identification information, the hash value and the signature information; and when the mobile terminal node acquires the block to be queried from the server node, the node verifies the block by comparing whether the hash value carried in the block is consistent with the hash value of the locally stored block.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a block verification method and device. Background technique [0002] Blockchain is a series of data blocks associated with each other using cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. [0003] The blockchain itself has its own verification capabilities, but the premise is that it must have a complete blockchain ledger. The blockchain itself requires each full node to update the complete blockchain ledger in real time, so that any node can verify any block. [0004] However, user terminals such as mobile phones often do not have the ability to serve as complete blockchain nodes. When other nodes send a block to the user terminal, the user terminal cannot verify the authenticity of t...
