Problems solved by technology

Common privacy transactions include ring signatures, zero-knowledge authentication, and DASH; among them, ring signatures and DASH only support transfer transactions, which cannot meet the privacy protection needs of users for various types of transactions; zero-knowledge authentication consumes huge resources. It is not suitable for clients to construct private transactions; moreover, none of these three private transactions can be supervised, and legal entities cannot protect individuals if necessary

Abstract

The invention provides a parallel chain transaction encryption method and device, and a storage medium. The method comprises the following steps: generating a first secret key and a random number; symmetrically encrypting a first payload and a random number of a first parallel chain transaction of the first parallel chain through a first secret key to generate payload encryption information, and performing hash operation on the payload encryption information to obtain a first hash value; replacing the first payload with the first hash value to generate a first private transaction, and sendingthe first private transaction to the main chain node; encrypting the first secret key according to the public key of each parallel chain node of the first parallel chain to generate a plurality of secret key encryption information; and respectively sending the corresponding secret key encryption information and payload encryption information to each parallel chain node. According to the invention,the parallel chain supports all types of private transactions, the privacy requirements of different users for the parallel chain transactions are met, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of blockchain, and specifically relates to a parachain transaction encryption method, device and storage medium. Background technique [0002] With the development of the main chain-parachain mechanism, more users hope that the parachain can also support private transactions. Common privacy transactions include ring signatures, zero-knowledge authentication, and DASH; among them, ring signatures and DASH only support transfer transactions, which cannot meet the privacy protection needs of users for various types of transactions; zero-knowledge authentication consumes huge resources. It is not suitable for clients to construct private transactions; moreover, none of these three private transactions can be supervised, and legal entities cannot protect individuals if necessary. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired ...
