Problems solved by technology

Fully public mode, which will lead to user data leakage
The fully encrypted mode requires nodes in the blockchain to obtain passwords from a system outside the blockchain network, and the system manages the passwords. That is to say, encrypted user data needs to rely on a centralized system to process The decryption operation, that is, the data access process depends on the central system, which increases the risk that the data access process is controlled by the central system, increases the insecurity of the data access process, and reduces the availability of user data

Abstract

The invention discloses a blockchain data processing method and device, electronic equipment and a medium, and relates to a blockchain technology. The method is executed by a transaction processing node in a trusted blockchain network, and specifically comprises the following steps: receiving a ciphertext of a transaction processing request from an initiator; wherein the ciphertext of the transaction processing request is obtained by encrypting the transaction processing request by adopting a first blockchain key; decrypting the ciphertext of the transaction processing request by adopting a second blockchain key of a local key storage area; and processing the decryption result to obtain result data. According to the embodiment of the invention, the centralization of decryption in the dataaccess process can be reduced, and meanwhile, the data security is improved.

Description

technical field [0001] The embodiments of the present application relate to computer technology, specifically to blockchain technology, and in particular to a blockchain data processing method, device, electronic equipment, and medium. Background technique [0002] Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission and consensus mechanism. [0003] In existing blockchain networks, user data can only be fully disclosed or fully encrypted. The fully public mode will lead to user data leakage. The fully encrypted mode requires nodes in the blockchain to obtain passwords from a system outside the blockchain network, and the system manages the passwords. That is to say, encrypted user data needs to rely on a centralized system to process The decryption operation, that is, the data access process depends on the central system, which increases the risk that the data access process is controlled by the central ...
