Problems solved by technology

However, in some application fields, the transaction information of blockchain nodes may include private information, and it is necessary to avoid providing data plaintext to each participating node. However, if the node does not have data plaintext, the node will not be able to verify the validity of the data, and ultimately cannot achieve the protection of the chain. purpose of uploading data
[0004] Therefore, the traditional public blockchain cannot better protect private transactions

Embodiment approach

[0058] The first implementation mode: if image 3 as shown, image 3 It is a schematic flowchart of encryption in a blockchain-based data processing method provided according to an exemplary embodiment of the present disclosure, the smart contract code and the first blockchain node executing the smart contract code The resulting data encryption may include the following steps.

[0059] In step S241, the secret key is randomly generated, and the secret key randomly generated this time is acquired.

[0060] In step S242, encrypt the smart contract code and the data generated by the first block chain node executing the smart contract code using the randomly generated secret key this time.

[0061] In step S243, the secret key randomly generated this time is updated into the digital envelope of the management contract.

[0062] Using the first implementation mode, before encrypting the smart contract code and the data generated by the first blockchain node executing the smart c...

Abstract

The present disclosure proposes a blockchain-based data processing method, device, storage medium, and electronic equipment to protect private transactions of blockchain nodes. The method includes: receiving a block in the blockchain network; the block includes sub-blocks, and the sub-blocks include smart contract codes and data corresponding to the smart contract codes; and obtain from the digital envelope of the management contract through the pre-acquired private key secret key; obtain the smart contract code in the sub-block according to the secret key, so that the first blockchain node executes the smart contract code; encrypt and write the smart contract code and the data generated by the smart contract code executed by the first blockchain node into the sub-block; write the sub-block into the block of the first blockchain node.

Description

technical field [0001] The present disclosure relates to the computer field, and in particular to a block chain-based data processing method, device, storage medium and electronic equipment. Background technique [0002] Blockchain technology is a distributed, decentralized, and trustless network data consensus storage technology, which realizes distributed computing based on a unique block (Block) generation mechanism and a P2P (Point to Point, point-to-point) network communication mechanism synchronization problem. [0003] For traditional public blockchains, the transaction information of any blockchain node is public, and any blockchain node can view the transaction information of other blockchain nodes. However, in some application fields, the transaction information of blockchain nodes may include private information, and it is necessary to avoid providing data plaintext to each participating node. However, if the node does not have data plaintext, the node will not b...
