The Beacon Chain was the name given to a ledger of accounts that conducted and coordinated the network of Ethereum stakers before those stakers started validating real Ethereum transactions. It did not process transactions or handle smart contract interactions.
It introduced the consensus engine (or "consensus layer") that took the place of proof-of-work mining on Ethereum and brought many significant improvements with it.
The Beacon Chain was a foundational component for the secure, environmentally friendly and scalable Ethereum we have now.
