Matter Labs, the team behind zkSync Lite (a first-generation Ethereum zk-rollup), launched the first public zkEVM solution, zkSync Era. The launch represents an important milestone for the adoption of zkEVM technology.
zkSync Era has notable differences from its optimistic rollup counterparts (i.e., Arbitrum and Optimism). These differences relate to security, capital efficiency, and transaction costs.
zkPorter is an interesting, upcoming innovation by Matter Labs and is an off-chain data availability solution that complements the zkSync Era rollup. zkPorter offers a significant upgrade in transaction speed and cost to current solutions.
zkSync Era has attracted a significant amount of TVL and unique deposit addresses since their March mainnet, especially when compared to competitors.
Some of this activity is likely in relation to a long-rumored airdrop for zkSync.
StarkNet, Polygon zkEVM, Scroll, Taiko, and Linea are also working on (or have released) competing zkEVM solutions.
