Securely Connecting Smart Contracts to Off-chain Data and Events

Описание: This talk covers the importance of data quality in both DeFi oracle solutions and blockchain oracles in general. Decentralized oracle networks should be delivering credentialed off-chain data utilizing high-quality data providers for smart contracts. This ensures that there is an end-to-end security guarantee when securing smart contracts that need external data.
