Starknet

About

Starknet is a Layer 2 (L2) blockchain network built on top of Ethereum. It makes Ethereum faster and much cheaper by processing thousands of transactions off-chain, then bundling them into a single secure proof (using advanced crypto tech called STARKs) that's verified on Ethereum.

In simple terms: It's like an express lane for Ethereum apps (DeFi, games, etc.), keeping the same high security but with lower fees and higher speed. Recently, it's also expanding to support Bitcoin features, like BTC staking and DeFi.
