BNB Smart Chain is implementing an upgrade called BEP 336 that aims to optimize data storage and processing on the blockchain, which will reduce transaction costs and enhance network performance. This upgrade is inspired by Ethereum's EIP 4844 and will introduce "Blob-Carrying Transactions" (BlobTx) to the network, streamlining the transaction verification process.

The upgrade will launch officially with the Haber hard fork on June 20, 2024. A blob is a temporary memory segment that can store large data chunks, up to 128 KB each. The network will only need to verify the data within the attached blob, instead of verifying each transaction individually within a block. The upgrade consists of a blob market, precompile contract, and blob propagation and gas price mechanism.

BEP 336 will have a significant impact on BNB Greenfield, enhancing decentralized storage, data integrity, accessibility, and longevity. The upgrade aims to reduce gas fees by up to 90%, making transactions on BSC more affordable. The temporary storage mechanism will keep the blockchain lean and bloat-free, enhancing overall network performance and data integrity.

Lower transaction costs and increased efficiency will make the BSC ecosystem more accessible to a wider audience. This upgrade will benefit opBNB and other Layer 2 solutions on BSC. The potential for innovation and growth within the BSC ecosystem has never been greater.

The BNB Smart Chain upgrade will introduce a new era of efficiency and cost-effectiveness for the network. With lower costs and improved efficiency, the BNB Chain ecosystem will be more accessible to developers and users. This upgrade will benefit opBNB and other L2 solutions on BSC, and following the hard fork, L2 networks building on BSC will enable this feature.
