Ethereum's scalability issues may find a solution in ZkSync, a zero-knowledge rollup scaling solution built on the Ethereum blockchain. ZkSync uses cryptographic techniques to process transactions off-chain, thereby reducing transaction fees and enhancing scalability. The platform, developed by Matter Labs, has attracted significant investment from Andreessen Horowitz, Sequoia Capital, and Balaji Srinivasan. ZkSync's unique features, including its early adoption and avoidance of a trusted setup, have positioned it as a frontrunner in scalable Ethereum solutions. Since its launch in November 2020, zkSync has processed millions of transactions and holds over $150 million in crypto assets.
