zkSync

zkSync is a trestles Layer 2 protocol for scalable low-cost payments on Ethereum, powered by zkRollup technology. It’s a user-centric zkRollup platform with security, user experience, and developer experience as the core focus.

Quick Facts

zkSync is a Layer 2 EVM-compatible blockchain
zkSync is a zkRollup, piggy backing on Ethereum, using Ethereum’s consensus mechanism, as well as their zero-knowledge proofs
zkSync is an Ethereum scaling solution

Version 1.0 launched has a theoretical limit of ~3,000 Transactions Per Second (TPS)
zkSync 2.0, now in Public Testnet, has a twofold goal: 1) arbitrary smart contract capabilities through support of both Solidity (via zkEVM) and Zinc (zkSync’s internal programming language), and 2) an exponential increase in throughput in the order of 20,000+ TPS via zkPorter (a protocol combining zkRollups and sharding)

zkSync’s transaction fees have two components:

Off-chain part (storage + prover costs): the cost of the state storage and the zero-knowledge proof (SNARK) generation. Internal benchmarks estimates ~$0.001 USD per transfer
On-chain part (gas costs): for every zkSync block, the validator must pay ETH gas to verify the SNARK, plus additionally ~0.4k gas per transaction to publish the state change. The on-chain part is a variable that depends on the current ETH gas price. However, this part is orders of magnitude cheaper than the cost of normal ETH/ERC20 transfers

zkSync does not currently have a native coin, although they have publicly stated their intent to create one.
