ZKsync is a Layer-2 zero-knowledge (ZK) rollup designed to scale the Ethereum network and reduce the cost of transacting on the blockchain. ZK rollup, which underpins the platform, is a trustless protocol that allows validators to confirm a transaction's authenticity without revealing any information about the transaction. As a result, the protocol preserves user privacy and security on the network while supporting faster and cheaper transaction processing.
Built by Matter Labs, ZKsync is the first zkEVM (Ethereum Virtual Machine) chain. It's designed to "look and feel like Ethereum," according to the project team, to help simplify adoption. Meanwhile, just like Ethereum, smart contracts are written using the Solidity and Vyper smart contract languages, and can be called via the same clients as other EVM-compatible chains.
How does ZKsync work?
ZKsync adopts ZK technology, a cryptographic method used to confirm the proof of a statement while obscuring any information about the statement itself. Think of the technology like an identity card that confirms you're an adult without revealing your actual age, name, or any other personal details.
ZK rollups help to improve the scalability of the Ethereum blockchain by performing computation and state offchain. The solution bundles transactions together at Layer-2 before they're posted on Layer-1. This method allows users to benefit from all the security advantages of Ethereum's base network but with higher throughput and lower fees.
ZKsync is compatible with EVM, and almost every smart contract written for EVM will be supported by the platform. That means most projects can be migrated over to the network with little to no modification.
Why is ZKsync significant?
ZKsync helps to address one of the most pressing limitations of the Ethereum network — scalability. Ethereum's relatively limited transaction throughput can lead to network congestion during periods of high demand, an issue that's only compounded as more users adopt the network. Meanwhile, congestion can lead to high gas fees, making transactions and interactions with decentralized applications costly. High latency is another challenge impacting the network's performance, as transactions are typically confirmed in a relatively slow 13 to 15 seconds.
ZKsync's use of ZK technology helps to ease these limitations while providing a platform that retains Ethereum's robust security and familiar usability. In theory, this should incentivize more developers to adopt Ethereum, strengthening the network's appeal at a time when competing solutions continue to launch.
ZK price and tokenomics
The ZK token has a total circulating supply of 21 billion. In June 2024, an airdrop was completed to distribute 17.5% of the token's supply to the project's community. Of the approximately 3.6 billion tokens reportedly airdropped to 695,232 wallets, 89% went to those who'd transacted on ZKsync — although the exact criteria wasn't announced — with 11% going to ecosystem contributors. This included ZKsync native projects, onchain communities, and builders. Meanwhile, 49.1% of the ZK supply will reportedly be distributed through "ecosystem initiatives", while 17.2% will go to investors and 16.1% will be allocated to Matter Labs members.
Due to a lack of liquidity, no ZK price was available as of the June 2024 ZK token airdrop. However, based on existing pre-launch futures available on Aevo, ZK perpetuals look to be trading at about $0.22.
About the ZKsync founders
ZKsync was developed by Berlin-based blockchain developer Matter Labs. The company was founded in 2018 by Alex Gluchowski and Alex Vlasov, and first deployed ZKsync to a closed testnet in December 2021. The platform was made publicly available on the mainnet on March 24, 2023.
The Matter Labs team, comprised of engineers, researchers, and technical experts, has made clear its focus on redrawing the limits of blockchain scalability through zk technology and open source developments. The organization is working towards the mainstream arrival of public blockchains, and is backed by numerous major players in the space, including the Ethereum Foundation.
