Securely Connecting Smart Contracts to Off-chain Data and Events

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. ________________ 0:27 - The Oracle Problem for Smart Contracts 3:40 - Decentralized Oracles for Smart Contracts & Decentralized Finance (DeFi) 5:00 - Off-chain and on-chain data for smart contracts 6:20 - Connecting any blockchain to all inputs and outputs 9:23 - Points of failure of centralized blockchain oracles 10:23 - Importance of data quality in decentralized oracles 13:00 - On-chain service agreements 19:00 - Provable performance history of Chainlink oracles 21:00 - Crypto-economic security from staking with Chainlink decentralized oracles 22:00 - Truly decentralized finance via decentralized oracles ________________ Chainlink is a decentralized oracle network that enables smart contracts to securely access off-chain data feeds, web APIs, and traditional bank payments.
