Ethereum Hard Fork (backward-incompatible network upgrade) Lifts Blob Limit to 21; RAKBank Gains In-Principle Approval for UAE Dirham (AED) Stablecoin (crypto pegged to fiat)
Ethereum’s Fusaka upgrade’s final BPO fork raises blob capacity, enhancing Layer2 scalability through temporary data storage, while RAKBank advances plans for a UAE dirham-backed stablecoin.
On July 7, Ethereum executed the second 'Blob Parameters Only' (BPO) fork as the final phase of its Fusaka upgrade, increasing the per-block blob limit from 15 to 21. Initially introduced in the March 2024 Dencun upgrade, blobs provide temporary large data storage for Layer2 transaction batches on the mainnet, automatically expiring after 18 days. The higher limit aims to improve data availability, lower rollup costs, and advance Ethereum’s scalability. Separately, RAKBank has obtained in-principle approval to launch a UAE dirham-backed stablecoin, designed to maintain parity with the national fiat currency.
- Hard fork: A backward-incompatible network upgrade that permanently splits protocol rules.
- Blob limit: A parameter capping data-chunk capacity for transactions, affecting scalability and costs.
- Stablecoin: A cryptocurrency pegged to a fiat currency to reduce price volatility.
