BNB Smart Chain (BSC) Advances with BEP 336: Introducing Blob Transactions for Enhanced Network Performance

BNB Smart Chain introduces BEP 336 upgrade, inspired by Ethereum’s EIP 4844, to optimize data storage and reduce transaction costs, preparing for a network performance boost.

The BNB Smart Chain (BSC) ecosystem is poised for a significant leap forward with the announcement of its upcoming major upgrade, BEP 336. This new development is set to revolutionize the way data is stored and processed on the blockchain, drawing inspiration from Ethereum’s EIP 4844. The implementation of BEP 336 promises to reduce transaction costs and enhance network performance, marking a milestone in BSC’s continuous evolution.

BEP 336 introduces a novel concept known as “Blob-Carrying Transactions” (BlobTx), which are designed to handle large data chunks in a cost-effective and temporary memory segment, with each blob capable of carrying up to 128 KB. The primary advantage of this approach is the reduction in the necessity to individually verify each transaction within a block. Instead, the network verifies the accuracy of the data contained in the attached blob, simplifying the transaction verification process.

This upgrade is particularly beneficial for opBNB, the Layer 2 network that operates under the BNB ecosystem. opBNB relies on BSC for data storage while utilizing its security features. The temporary nature of blobs means they don’t consume network space indefinitely, which translates to lower storage costs and, consequently, reduced gas fees for users.

Key components of BEP 336 include a Blob Market, which introduces a fee market for blobs to regulate costs according to network demand, and a Precompile Contract, which further secures the network by verifying that blob data matches its transaction reference.

BSC’s unique architecture has necessitated the development of a bespoke strategy for blob propagation and persistence, distinguishing it from Ethereum’s approach. Moreover, BSC will implement a dynamic gas pricing mechanism for blobs, with minimum and maximum thresholds to maintain reasonable transaction costs, a feature absent from Ethereum’s implementation.

The phased rollout plan for BEP 336 begins with a testnet launch in April, allowing developers to assess and interact with the upgrade. This will be followed by a Magnet phase in May for continued testing and optimization, culminating in a Mainnet hard fork in June, marking the official deployment of BEP 336.

The anticipated benefits of this upgrade extend across the BSC ecosystem. Users can expect reduced gas fees and more efficient data management, which together ensure the blockchain remains bloat-free, enhancing overall network performance. These improvements make BSC more user-friendly and accessible, potentially attracting a wider audience, from experienced developers to newcomers to blockchain technology.

Looking ahead, BNB Chain has a strategic vision for 2024, with a focus on enhancing scalability and user experience. “Parallel EVM Re-Architecture” is one such initiative aimed at significantly boosting transaction processing and scalability. BNB Chain is also developing opBNB further, with the “Rollup as a Service” (RaaS) initiative to support large-scale Dapps in developing customized L2 solutions, and implementing a “path-based storage scheme” (PBSS) to further optimize storage.

In conclusion, BEP 336 reflects BNB Chain’s proactive and innovative approach to addressing the challenges of data management and transaction costs. The upgrade is a testament to BNB Chain’s commitment to scalability and efficiency, setting the stage for a transformative period in the network’s growth.
