Blockchain-based data processing method, device, storage medium and terminal

Abstract

The embodiment of the present application discloses a blockchain-based data processing method, device, storage medium, and terminal, wherein the method includes: determining block index information based on a locally stored target block set, in which the target block set Including at least one block read from the target full node device of the blockchain network, read from the first reference full node device of the blockchain network according to the block index information for the target A reference block set for verification by a block set, the first reference full-scale node device is a full-scale node device in the blockchain network other than the target full-scale node device, and the reference block set is used to verify the The validity of each block in the target block set. Through the embodiment of the present application, it can be verified whether the block read from the block chain is a valid block, and the security of the local storage block is improved.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a data processing method, device, computer storage medium and terminal based on blockchain. Background technique [0002] Blockchain is a new application mode of distributed data storage, point-to-point transmission (P2P transmission), consensus mechanism, encryption algorithm and other computer technologies. Let multiple parties efficiently store data and read the stored data. In practice, it has been found that there are behaviors of illegal personnel seeking profits by forging the blockchain, that is, forging the blockchain can refer to the behavior of storing invalid blocks in the blockchain; or, due to writing blocks to the blockchain In the process, due to the poor quality of network communication, invalid blocks are stored in the blockchain. Invalid blocks can refer to missing data, inaccurate data, etc. in the block, which makes it impossible for users ...

In practice, it has been found that there are behaviors of illegal personnel seeking profits by forging the blockchain, that is, forging the blockchain can refer to the behavior of storing invalid blocks in the blockchain; or, due to writing blocks to the blockchain In the process, due to the poor quality of network communication, invalid blocks are stored in the blockchain

Invalid block can refer to missing data, inaccurate data, etc. in the block, which makes the user unable to confirm whether the block read from the blockchain is a valid block

If invalid blocks in the blockchain are read and used to perform corresponding operations, it will bring a lot of inconvenience to users

For example, a block in the blockchain stores fake transaction address information. If the block storing fake transaction address information is read and used to perform resource transfer, the resource transfer will fail
