Before we can understand zkBNB, we must first understand zk Rollups or zero knowledge Rollups.

What is zk(zero knowledge) Rollups?

ZK Rollups is a Layer-2 solution that performs all calculations and state changes off-chain, i.e. on a sidechain. With this design, a description of the alterations, as well as specific cryptographic proofs proving their authenticity are posted to the Mainnet later.

What is zkBNB?

ZkBNB is based on the ZK Rollup architecture, which bundles hundreds of transactions off-chain and generates cryptographic proofs such as SNARKs to validate them.

This implies that funds are maintained on BSC while computation and storage are handled by Binance's Side Chains, resulting in lower costs and faster performance. zkBNB can achieve the same security as BNB by using zkSNARKs.

So, if you are a developer creating large-scale BSC-based apps with high throughput and low transaction fees, zkBNB is the best infrastructure you can get.

What does zkBNB provide?

  • Security - With the usage of zkSNARKs, zkBNB has the same degree of security as its L1 BNB Chain.

  • Seamless Transactions - BNB and BEP20/BEP721/BEP1155 tokens generated on BSC or ZkBNB can easily transfer between the two systems seamlessly.

  • High TPS - Fast transaction speed and faster finality.

  • Higher Transparency - If a user believes that his transactions are being censored by ZkBNB, he or she can request a "full exit" operation to withdraw funds at any moment. This implies that consumers can withdraw their money at any moment from L2 to L1.

Conclusion

ZkBNB from BNB Chain is an innovation that aims to have a substantial influence on the development of large-scale BNB Smart Chain-based applications with assured security and transaction speed, faster finality, and much lower transaction fees.

Its debut follows the earlier this year announcement of BNB sidechains, a platform for constructing sidechains within the BNB Chain ecosystem.

The Mainnet is scheduled to launch in Q1 of 2023, Therefore let us hope that it will be a significant milestone in the BSC Ecosystem.
