TLDR
ETH blob fees rose from near zero to a meaningful floor after the Fusaka upgrade. A new rule ties the minimum blob base fee to L1 execution fees, improving pricing and ETH burn Bitwise analyst summary.
- Minimum blob fee is now roughly execution base fee divided by 16, restoring a functioning fee market Bitwise summary.
- Reports show an immediate jump from 1 wei to about 1,500 wei (roughly 1,500x) after activation media coverage.
- Capacity will rise via BPO steps (Dec 9 and Jan 7), which may stabilize fees as blob supply increases foundation post.
Deep Dive
1. Fee Floor
The key change is EIP?7918, which sets a minimum blob base fee tied to L1 execution costs. Multiple analyses describe the new floor as roughly the execution base fee divided by 16, ending the near?free blob periods that undermined ETH burn and fair resource pricing as rollups grew Bitwise summary. Blockworks adds that reserve pricing should make blob fees more stable and predictable over time market analysis.
L2s now pay economically meaningful data?availability costs, which can improve ETH burn and align network usage with value accrual.
2. Spike Magnitude
Right after Fusaka went live, several reports noted blob fees jumping from 1 wei to around 1,500 wei, a roughly 1,500x change from the pre?upgrade floor that had often stuck at 1 wei in quiet periods media coverage. The immediate spike reflects a restored fee market where price can steer blob demand rather than defaulting to near zero market analysis.
Fees moved from symbolic to market?reflective pricing. Near term, L2 operating costs for data posting rise, then normalize as capacity and demand rebalance.
3. Capacity Next
PeerDAS increases effective throughput by letting validators sample blob data rather than store it all, enabling more blobs per block without centralizing hardware requirements foundation post. Blob?Parameter?Only (BPO) upgrades are scheduled to raise blob targets and maxes (Dec 9 to target 10 and max 15, Jan 7 to target 14 and max 21), which should expand supply and help stabilize blob fees as usage scales foundation post. Analysts expect the combination of PeerDAS and reserve pricing to create a more rational data?availability market and potentially strengthen ETHs deflationary burn when activity grows market analysis.
More blob capacity should temper fee spikes and support lower, more predictable L2 costs as throughput rises.
Conclusion
Blob fees shifted from nominal to market?based pricing with a new minimum tied to L1 execution fees, creating a fairer cost for data availability and improving ETH burn. Short?term fee spikes reflect the restored market, while PeerDAS and scheduled capacity increases should stabilize blob fees and support scalable, lower?cost L2 activity over the next weeks.
