Example Embodiment

[0057] Wherein, the method of encrypting the data generated by executing the smart contract code on the smart contract code and the first blockchain node in step S24 includes but is not limited to the following two implementation modes:

[0058] The first implementation: such as image 3 As shown, image 3 It is a schematic flow diagram 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 execute the smart contract code The generated data encryption can include the following steps.

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

[0060] In step S242, the smart contract code and the data generated by the first blockchain node executing the smart contract code are encrypted with the secret key generated randomly this time.

[0061] In step S243, the key generated randomly this time ...

Abstract

The present disclosure proposes a block chain-based data processing method, apparatus, storage medium, and electronic device for protecting a private transaction of a block chain node. The method includes: receiving a block in a blockchain network; the block includes a sub-block, the sub-block includes data corresponding to the smart contract code and the smart contract code; and obtaining the private key from the management contract by using a pre-acquired private key a secret key; obtaining a smart contract code in the sub-block according to the secret key, so that the first block chain nodeexecutes the smart contract code; encrypting and writing the data generated by the smart contract code and the block chain node to execute the smart contract code In the block; the sub-block is written into the block of the block chain 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...
