BNB Chain to Launch Application-Specific Sidechains to Reduce Network Strain 

BNB Chain is on the move to add application-specific sidechains to the blockchain to help with scalability and streamline data-heavy applications like gaming and the metaverse.

BNB Chain, formerly known as Binance Smart Chain (BSC), the Layer 1 solution developed by Binance, will start including sidechains to improve its scalability. Similar to Polkadot’s (DOT) parachains, these BNB Chain Application Sidechains (BAS) aim to cut costs and increase the speed of transactions for resource-intense applications such as gaming, SocialFi, and the metaverse.

Binance Labs – the core development team of BNB Chain – has yet to reveal all the technical details. However, the possibility has been ruled out that these sidechains become equal layer 1 blockchains, which is the case with parachains.

A BNB Chain spokesperson told The Block:


The BAS is an infrastructure introduced to help developers and node operators build and run their own blockchain as their internal value system for a massive number of users while still maintaining a close connection with BNB Chain.

It’s All About the Use Case

The point of application-specific sidechains is to allow each chain to focus on a specific use case. According to the BNB spokesperson, the sidechains will host BNB-compatible dApps and will be able to operate independently of the mainnet – allowing teams to customise for their own security needs, instead of relying on the mainnet.

Sidechains to Open Doors for Large-Scale Applications

A valid comparison to BAS is Ronin, a sidechain on Ethereum dedicated solely to Axie Infinity’s play-to-earn game. Similarly, the very first BAS testnet will focus on GameFi, according to the BNB spokesperson.

BNB Chain ecosystem coordinator Samy Karim has mentioned previously that “BNB Chain will embrace large-scale applications, including GameFi, SocialFi and the Metaverse. In particular, scaling from one chain to multi-chain, improving scaling solutions and expanding the validator set of BSC from 21 to 41 (with 20 validators functioning as candidate block producers).”

Binance has been making various moves as of late, from acquiring traditional businesses and bringing them into the crypto space to now adding sidechains to facilitate specific use cases. The centralised giant may still have a big role to play in the crypto space.
