In anticipation of Fusaka, we urge all blob originators to update their software to create Cell Proofs instead of blob proofs. Background One underdiscussed aspect of EIP-7594 (PeerDAS) is that it changes the format for proofs from blob proofs to cell proofs. This allows for downloading a specific part of the blob instead of the whole blob for data availability sampling. This change might break user applications that send blob…

Starting with the upcoming Fusaka hard fork, EIP-7825 introduces a per-transaction gas limit cap of 2²⁴ (≈ 16.78 million gas). This change is already live on Holesky and Sepolia, and will activate on mainnet with Fusaka. Developers and users who rely on very large transactions should verify that their contracts and transaction builders conform to the new cap. Background As Ethereum scales to higher block gas limits and prepares for parallel execution (e.g. EIP-7928 in Glamsterdam), the Fusaka fork introduces a per-transaction gas limit cap. Previously, a single transaction could consume the entire block gas limit (~45 million gas), creating…
