The BNB Chain has activated its Haber hard fork, which introduces BNB Evolution Proposal (BEP)-336, aiming to optimize data storage and processing on the network. This significant upgrade has led to a substantial reduction in blockchain fees, with notable impacts on layer-2 costs and transaction verification.

Key Features of the Haber Hard Fork

Activation and Goals:
- Activation Date: June 20
- Primary Objective: To optimize data storage and processing on the BNB Smart Chain (BSC) by implementing BEP-336.

BEP-336 and Its Impact:
- Inspiration: BEP-336 is inspired by Ethereum Improvement Proposal (EIP)-4844.
- Blob-Carrying Transactions: This concept streamlines the verification process, allowing transactions to be verified within a blob, a temporary memory segment that captures large data chunks, rather than individually within a block.

Reduction in Costs:
- Layer-2 Cost Reduction: With BEP-336, layer-2 costs on the BSC are reduced by 90%.
- Optimistic Rollup Layer-2 Solution (opBNB): Network fees on opBNB are reduced to around $0.0001.

Differences from Ethereum’s Approach

BSC-Specific Adjustments:
- Blob Management: Blobs on BSC are managed solely by the BSC client, differing from Ethereum’s approach.
- Pricing Mechanism: Unlike Ethereum’s fee-burning mechanism, BSC does not burn the base fee within blobs, instead tailoring its pricing mechanism to fit its network needs.

Enhancements to BNB Greenfield

BlobHub Implementation:
- Decentralized Storage Solution: BNB Greenfield’s decentralized storage and data management will be enhanced by "BlobHub," a data archive layer.
- Optimization for DApps and Layer-2 Networks: This layer will optimize data storage, benefiting decentralized applications (DApps) and layer-2 networks on BNB Chain.

Market Impact and BNB Price Performance

BNB Token Milestone:
- All-Time High: BNB tokens reached an all-time high of $717.48 on June 6.
- Price Correction: Following the milestone, the price corrected to $579 on June 18, currently stabilizing around $605.

Market Performance:
- Price Gain: BNB gained 19% in the first week of June, outperforming the broader crypto market's 4.2% increase.
- Trader Sentiment: Despite the gains, traders are cautious about the rally's sustainability and are looking for indicators to support continued momentum.

Conclusion

The Haber hard fork and BEP-336 mark significant advancements for the BNB Chain, enhancing both data storage efficiency and reducing transaction costs. These improvements are expected to bolster the network’s scalability and appeal, particularly for layer-2 solutions and decentralized applications. Coupled with BNB’s recent price performance, these updates position the BNB Chain for sustained growth and increased adoption in the evolving blockchain ecosystem.
