Understanding Public-Key Cryptography

Public-key cryptography is a fundamental concept to the inner mechanisms of blockchains, powering an important building block of decentralized blockchains—crypto wallets.

In this Blockchain Basics episode, Chainlink Labs Developer Advocate Zak Ayesh explains the difference between asymmetric and symmetric cryptography, how public and private key encryption works in blockchains, and why this technology is fundamental to Web3.

Chainlink is the industry standard for building, accessing, and selling oracle services needed to power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts with a way to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink currently secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries, and offers global enterprises and leading data providers a universal gateway to all blockchains.
