Fusaka went live on December 3rd, 2025 with 12 EIPs. It scales both Ethereum Mainnet and blobs, and makes sure growing blob use contributes to the network's economics.
Scaling Blobs
Blob capacity grows in steps through Blob-Parameter-Only (BPO) upgrades (EIP-7892): small forks that change only blob parameters, giving rollups more room for data. PeerDAS (EIP-7594) makes the extra load safe, because nodes verify blobs by sampling them instead of downloading them in full.
- BPO1 (December 9th, 2025): target raised from 6 to 10 blobs per block, maximum 15.
- BPO2 (January 7th, 2026): target raised from 10 to 14 blobs per block, maximum 21.
Scaling L1 Gas
EIP-7935 set the default L1 block gas limit to 60M (implying a 30M target); however, the network reached this level shortly before the fork via validator signaling, which allows gradual gas limit adjustments independent of hard-fork activation.
Sustainable Economics for Blobs
Historically, the majority of ETH burned has come from L1 gas fees. With the introduction of blob fees, Ethereum added a second onchain burn mechanism. While blob-related burn is currently small relative to execution gas fees, it is growing as blob usage scales. Fusaka reinforces Ethereum’s commitment to the long-term monetization of blobs, ensuring that increased blob adoption contributes to the network’s economic sustainability.
EIP-7918 Deep Dive
EIP-7918 introduces a floor on blob gas price by bounding the blob base fee to execution gas prices, ensuring that the cost of 'GASPERBLOB' blob gas cannot fall below the equivalent execution cost ('BLOBBASECOST' × 'basefeepergas'). When this floor binds, excess blob gas accumulates without subtracting the target, tightening the blob fee market and anchoring blob pricing to L1 execution economics.
