Comparing zkSync, Polygon zkEVM, and zk-BNB for Scalability Solutions


ZK Rollups are a layer-2 solution that collects transactions off the main blockchain and batch them into a single transaction, thereby increasing throughput while reducing gas fees. ‍


  • Zero-Knowledge Rollups (ZK Rollups) are a Layer-2 solution for blockchain scalability.
  • zkSync uses zk-rollups for Ethereum’s layer-two blockchain, with gas fees 1/100 of L1 gas and reportedly supporting over 100,000 transactions per second.
  • Polygon zkEVM uses zero-knowledge proofs to reduce transaction costs and increase throughput while inheriting Ethereum’s security, with a lower throughput of 2,000 TPS.
  • ZkBNB can package hundreds of transactions and generate cryptographic proofs as zkRollups, allowing users to trade digital assets without permission and offering developers the opportunity to build marketplaces for NFTs.
  • The three zk solutions are developer-friendly, allowing easy porting of Ethereum dApps.

Zk Rollup: Layer-2 Solutions for Blockchain Scalability

Blockchain technology has come a long way in recent years, but one problem still looms large: scalability. As the number of users…
