Overview

zkSync is a scaling and privacy engine for Ethereum. Its current functionality scope includes low gas transfers of ETH and ERC20 tokens in the Ethereum network, atomic swaps & limit orders as well as native L2 NFT support. This document is a high-level description of the zkSync development ecosystem.

zkSync is built on ZK Rollup architecture. ZK Rollup is an L2 scaling solution in which all funds are held by a smart contract on the mainchain, while computation and storage are performed off-chain. For every Rollup block, a state transition zero-knowledge proof (SNARK) is generated and verified by the mainchain contract. This SNARK includes the proof of the validity of every single transaction in the Rollup block. Additionally, the public data update for every block is published over the mainchain network in the cheap calldata.

Q2. ZkSync is a scaling solution for Ethereum that is live on mainnet. Some of the main features of ZkSync are the extremely low transaction fees and trustless protocol design. You can read more about ZkSync here.

Users can also deposit ERC20 tokens into ZkSync. Which ERC20 tokens have been deposited the most (in $ volume and total count) in the last 60 days? Visualize and explain both findings.
