How Does BNB Chain Rollup zkBNB Fit In the Layer-Two Ecosystem?

ZkBNB in the L2 Ecosystem

The defining characteristic of the new Zero-Knowledge Rollup, zkBNB, is that it is a layer-two (L2) solution to scale BNB Chain, while most L2 solutions are designed to scale Ethereum.

According to Binance Research’s recent “Layer 2 Scaling Market Update,” there appears to be a preference for rollups (Optimistic and ZK) over other L2 scaling solutions such as Side Chains, State Channels, and Plasma.

Binance Research opined that ZK-Rollups are preferable because they are built to offer more in terms of security, performance, usability, “and other noteworthy aspects.”

According to the report, the zkBNB mainnet is targeted to launch early next year. The rollup can reduce gas fees by 90%, support 100 million addresses, and handle up to 10,000 transactions per second (TPS). BNB Chain, by comparison, can handle a maximum of 300 TPS.

On Ethereum, optimistic rollups Arbitrum and Optimism are the dominate L2s, accounting for more than 80% of market share, according to L2BEAT.

Meanwhile, two other L2s, Polygon’s zkEVM and zkSYNC 2.0 recently launched public testnet versions.

With all the developments going on in the L2 ecosystem, zkBNB finds itself surrounded by good company, and competition.

What Is BNB Chain:

Previously known as the Binance Smart Chain (BSC), BNB Chain is a community-driven, decentralized, and censorship-resistant blockchain that is powered by Binance. It consists of BNB Beacon Chain and BNB Smart Chain, EVM compatible and facilitating a multi-chain ecosystem. Through the concept of MetaFI, BNB Chain aims to build the infrastructure to power the world’s parallel virtual ecosystem.
