ZKsync (ZK) is a Layer-2 scaling solution for Ethereum. It uses zero-knowledge rollups (zk-rollups) to enhance the scalability and efficiency of Ethereum. This technology allows ZKsync to process many transactions off-chain and then post a single proof to the Ethereum mainnet, significantly increasing transaction speed and reducing costs.
ZKsync aims to maintain Ethereum's security while providing higher throughput. It can handle thousands of transactions per second, compared to Ethereum's lower capacity. This makes ZKsync ideal for applications that require high transaction volumes, like decentralized exchanges and gaming platforms.
One of the unique features of ZKsync is its support for EVM-compatible smart contracts, allowing developers to deploy their Ethereum-based applications with minimal changes. Additionally, ZKsync reduces gas fees substantially, making transactions up to 100 times cheaper than on Ethereum.
The platform ensures security through zero-knowledge proofs, which validate transactions without revealing their details. This maintains the integrity of transactions and ensures they are secure even if the Layer-2 system encounters issues.
ZKsync's development is led by Matter Labs, which has raised significant funding to advance the technology. The project continues to grow, with a robust ecosystem of decentralized applications (dApps) being built on it.
Here's a deep dive into ZKsync and how it works.
