Abstract

Blockchain has gained traction for its decentralized nature, transaction security, transparency, and immutability. However, integrating external information requires using oracle services, which introduce complexities and vulnerabilities that can compromise the reliability and integrity of blockchain-based applications. This paper addresses the challenge of oracle decentralization using our MetaMail system as an example. MetaMail enables user authentication and transaction confirmation in Ethereum via email (using OAuth 2.0 protocol). Initially relying on a centralized oracle, the MetaMail system faced vulnerabilities with the oracle as a single point of failure. The proposed Decentralized Oracle Network (DON) enhances user authentication, validation reliability, security, and trustworthiness, effectively mitigating risks connected to centralized oracles. We discuss the DON's architecture and security considerations. The comparative analysis highlights the advantages of a decentralized approach and emphasizes the potential of DONs for user authentication and data validation in blockchain-based applications.
