Problems solved by technology

[0003] At present, the two biggest challenges in the technology of enterprise-level blockchain platforms are privacy and performance, and it is often difficult to solve these two challenges at the same time
Most solutions trade for privacy by losing performance, or pursue performance without much consideration for privacy
Common encryption technologies to solve privacy problems, such as Homomorphic encryption and zero-knowledge proof, have high complexity, poor versatility, and may cause serious performance loss

Abstract

One or more embodiments of this instructions provide a receipt storage method and node that combines user types and transaction types. This method can include: the first blockchain node receiving encrypted transactions; the first blockchain node is credibleThe transaction content of the transaction described and executed in the execution environment obtains the receipt data; the first blockchain node determines the exposure field in the transaction of the transaction according to the type of transaction of the transaction;According to data, when the trading initiator belongs to the preset user type, the exposed fields are stored in bright text, and the remaining receipts fields are stored in ciphertext.The data is stored in the form of a ciphertext.

Description

Technical field[0001]One or more embodiments of the present specification relate to the field of block chains, and more particularly to a receipt storage method and node that binds to the user type and transaction type.Background technique[0002]The block chain technology is constructed above the transmission network (such as point-to-point network). The network node in the transmission network uses a chain data structure to verify and store data and use a distributed node consensus algorithm to generate and update data.[0003]The current largest two challenges in the current enterprise-level block chain platform is privacy and performance, and it is often solved simultaneously with these two challenges. Most solutions are privacy by losses, or have no privacy to pursue performance. Commonly solved privacy issues, such as homomorphic encryption, and zero-know proof, high, universality, and poor performance, and may also bring severe performance loss.[0004]Trusted Execution Environment...
