Ethereum Virtual Machine

The runtime environment for executing smart contracts on the Ethereum blockchain network.

Oracle

A service that provides external real-world data to blockchain smart contracts that cannot access off-chain information directly.

Chainlink

Scaling solutions built on top of a base blockchain that process transactions off-chain while inheriting security from the main chain.
