Abstract

Abstract: As a new infrastructure to build trust, blockchain is not perfect in the protection of trusted data feed to smart contracts. Firstly, this paper analyzes the necessity of trusted data feed, and studies the Oracle based trusted data feed technology. On this basis, the concept and overall architecture of Oracle are clarified, and the trusted data feed of Oracle is analyzed from two aspects of trusted mechanism and application practice.

Key words: blockchain, Oracle, privacy protection technology, trusted data feed
