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. All other embodiments obtained based on the embodiments of the present invention belong to the protection scope of the present invention.

[0033] Since the block header of each block contains the compressed value of the transaction information of the previous block, this makes a long chain formed from the genesis block (the first block) to the current block. Since there is no way to generate the current block without knowing the "transaction miniature" value of the previous block, each block must follow the previous block in chronological order. Thi...

Abstract

The invention provides a fault monitoring method and device, equipment and a computer readable storage medium. The method comprises the following steps: judging whether a current main node has a faultor not according to the adding condition of a new block; If yes, sending a view replacement request to a timestamp server, and the view replacement request comprises fault information of the main node; Receiving a view replacement request comprising a timestamp fed back by the timestamp server, broadcasting the view replacement request comprising the timestamp to the block chain, the view replacement request comprising the timestamp being fed back after the timestamp server verifies that the view replacement request is legal; Determining whether the number of the received view replacement requests including the timestamps exceeds a preset first threshold value or not; If yes, judging whether the block chain achieves consensus on the view replacement request comprising the timestamp or notaccording to a preset judgment rule; If yes, setting the preset standby node as the current main node, determining the state of the main node in time, and carrying out view switching in time under the condition that a fault occurs.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a fault monitoring method, device, equipment and computer-readable storage medium. Background technique [0002] Blockchain (Blockchain) is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it records all transaction records. 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. The blockchain is public on the network and can be queried in every offline bitcoin wallet data. The function of the Bitcoin wallet depends on the confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations to proceed.
