Embodiment Construction

[0020] The inventor of the present application found that the block data in the existing blockchain cannot be deleted, because after deletion, after the newly added nodes obtain the data of the blockchain, they cannot verify the correctness of the block data. Therefore, in the face of continuous growth of blockchain data, old data cannot generate business value, but cannot be deleted, and will occupy a large amount of storage and computing resources.

[0021] An embodiment of the present invention provides a data processing method for a blockchain network. The data processing method includes: in response to the block data stored in the preset storage space being deleted, generating a deletion indicator, the deletion indicator indicating Deleted block data, the preset storage space can be accessed by at least one block chain node in the block chain network, the block data is associated with the target block; adding the deletion identifier to the list of deleted data , the delet...

Abstract

A data processing, block generation and synchronization method for block link networks, a computing device, and a storage medium are provided, the data processing method includes: A. generating a deletion flag indicating deleted block data in response to deletion of block data stored in a preset storage space accessible by at least one block chain node in a block chain network, the block data being associated with a target block; B. adding that deletion mark into the deleted data list, and store the deleted data list in the preset storage space. The technical proposal of the invention can realize the deletion of the block data associated with each block in the block chain.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a data processing, block generation and synchronization method for block chain networks. Background technique [0002] Blockchain is an intelligent peer-to-peer network that uses distributed databases to identify, disseminate and record information, also known as the Internet of Value. Blockchain technology includes storing data in a block structure, using cryptography to ensure transmission and access security, etc., which can realize data consistent storage, anti-tampering, and a decentralized technical system. [0003] Currently, in some blockchain networks, each node has a full copy of ledger data. As the business develops, the data on the ledger will continue to grow. The data in the blockchain is divided into blocks for storage, and each block includes the hash value (HASH) of the previous block, the HASH of this block and the data of this block. The HASH of this bl...
