Ethereum just pulled off something critics said was impossible: making Layer-1 transactions genuinely affordable. Following the December 3 Fusaka upgrade activation, average Ethereum gas fees have plummeted to approximately $0.01 per transaction—down from $5+ during peak 2024 periods and a fraction of the $30-50 fees that plagued users in 2021. Twitter is buzzing with screenshots showing transactions costing literal subcents, with some users reporting fees as low as $0.01-0.10 for simple transfers.
The transformation comes from Ethereum‘s one-two punch of major 2025 upgrades: Pectra in May and Fusaka this week. Together, they’ve increased the network’s gas limit from 30 million to 60 million (with targets for 150 million), introduced PeerDAS technology that revolutionizes data availability, and fundamentally restructured how blob fees work. For Layer-2 networks like Arbitrum and Optimism that settle on Ethereum, costs have become almost negligible—often under a penny per transaction.
This isn’t just a technical milestone; it’s an existential moment for Ethereum. With Solana processing transactions for fractions of a cent and eating Ethereum’s lunch on DeFi and NFT activity, the network desperately needed to prove it could scale without sacrificing decentralization. The question now: will subcent fees bring users and developers back to Ethereum, or has Solana’s momentum already shifted the industry’s center of gravity?
The Fusaka Upgrade: What Actually Happened December 3
Ethereum’s Fusaka upgrade (combining “Fulu” consensus layer + “Osaka” execution layer updates) went live December 3, 2025 at approximately 21:49 UTC. The activation marked Ethereum’s second major upgrade of 2025 following May’s Pectra fork, and represents the most significant scalability improvement since The Merge in 2022.
Core Technical Changes:
PeerDAS (Peer Data Availability Sampling): The headline feature allows validators to verify data exists without downloading entire blobs. Currently, every validator must download all blob data to verify Layer-2 transactions—a resource-intensive process that limits throughput. PeerDAS enables validators to sample small portions of data and mathematically prove the full dataset exists.
This changes the scalability equation dramatically. Without PeerDAS, increasing blob capacity would eventually require validators to run expensive hardware, threatening decentralization. With PeerDAS, Ethereum can scale to 100,000+ transactions per second across its Layer-2 ecosystem while keeping validator requirements reasonable.
Gas Limit Increase to 60M: Fusaka raised Ethereum’s block gas limit from 45 million to 60 million, with future targets of 150 million. This represents a 33% immediate throughput increase and roughly doubles capacity compared to early 2024. More transactions fit in each block, reducing congestion and lowering fees.
Critically, EIP-7825 introduced a per-transaction gas cap of 16.78 million to prevent denial-of-service attacks. Even with higher block capacity, no single transaction can monopolize an entire block, ensuring network stability.
Blob Fee Structure Reform (EIP-7918): Post-Dencun (March 2024), blob fees could drop to near-zero during quiet periods—effectively subsidizing Layer-2 networks unsustainably. Fusaka introduces a minimum blob base fee that fluctuates between 0.01 and 0.5 Gwei, establishing a “reserve” system that prevents fees from collapsing to zero while keeping them predictably low.
This ensures Ethereum captures value from Layer-2 activity (important for ETH economics) without creating prohibitive costs. Layer-2 users won’t see fee spikes; they’ll experience stable, low-cost transactions that properly compensate the network.
Blob Capacity Expansion: Fusaka increases the blob target from 6 to 10 on December 9, then to 14 on January 7. These “blobs” are temporary data storage containers where Layer-2 networks post transaction data cheaply. More blob space = more Layer-2 capacity = lower user fees.
How Cheap Is Ethereum Now?
Layer-1 Mainnet Fees:
- Current Average: $0.31 per transaction (late November 2025)
- 2024 Peak Average: ~$5 per transaction
- 2021 Bull Market: $30-50+ per transaction
- Simple Transfer Cost: $0.01-0.39 (depending on complexity and network load)
The $0.31 average represents a 95% reduction from 2024 peaks and makes Ethereum mainnet viable for everyday transactions for the first time in years.
Layer-2 Fee Revolution: Following Dencun’s March 2024 introduction of blobs, Layer-2 fees dropped from $0.50-$3.00 to $0.01-0.10. Fusaka’s blob expansion and PeerDAS should push fees even lower—potentially under $0.01 for most transactions.
For context, Optimism and Arbitrum users are reporting transaction costs of $0.005-0.02, making them competitive with Solana’s $0.0001-0.001 average fees. While not quite as cheap, the gap has narrowed from 1000x to perhaps 5-10x.
Comparison to Competitors:
- Solana: $0.0001-0.001 per transaction
- Ethereum L1 (Post-Fusaka): $0.01-0.39
- Ethereum L2 (Post-Fusaka): $0.005-0.02
- Bitcoin: $1-5+ (depending on mempool congestion)
Ethereum L2s are now within striking distance of Solana on cost, while offering Ethereum’s security and decentralization guarantees.
Why This Took So Long: Ethereum’s Scaling Journey
Ethereum’s fee problems aren’t new—they’ve plagued the network since the 2017 ICO boom. Understanding why resolution took 8+ years reveals the difficulty of scaling decentralized blockchains.
The Trilemma: Blockchains face a fundamental tradeoff between decentralization, security, and scalability. You can optimize for two, but achieving all three simultaneously is nearly impossible:
- Increase throughput too much → nodes can’t keep up → centralization risk
- Lower hardware requirements → easier to attack → security risk
- Prioritize decentralization + security → limited throughput → high fees
Ethereum’s Philosophical Stance: Unlike Solana (which prioritizes throughput) or Bitcoin (which prioritizes security), Ethereum committed to maintaining decentralization above all else. This meant rejecting simple solutions like dramatically increasing block size (which would require expensive validator hardware) in favor of complex, years-long research into Layer-2 rollups and data availability sampling.
The Upgrade Sequence:
- The Merge (2022): Switched to Proof-of-Stake, reducing energy usage 99.95% but not increasing throughput
- Dencun (March 2024): Introduced blobs, slashing Layer-2 fees 90-95%
- Pectra (May 2025): Increased validator flexibility, raised gas limit to 36M, doubled blob capacity to 6 target/9 max
- Fusaka (December 2025): PeerDAS enables massive scaling, gas limit hits 60M with 150M target, blob fees stabilize
Each upgrade built on previous work, with Fusaka representing culmination of years of research into data availability sampling, cryptographic proofs, and economic mechanism design.
PeerDAS Explained: The Technology Enabling Cheap Fees
PeerDAS (Peer Data Availability Sampling) sounds technical, but the concept is straightforward:
The Old Problem: Every Ethereum validator must download and verify all blob data posted by Layer-2 networks. As blob usage increases (more Layer-2 activity), validators need more bandwidth and storage. Eventually, only well-funded entities can afford to validate, threatening decentralization.
The PeerDAS Solution: Instead of downloading everything, validators randomly sample small portions of blob data from peers. Using mathematical techniques (erasure coding and polynomial commitments), validators can prove with high confidence that the full dataset exists and is correct—without downloading it entirely.
Think of it like quality control: instead of inspecting every product on an assembly line, you randomly sample a few items. If samples consistently pass inspection, you can be statistically confident the entire batch is good.
Why This Matters: PeerDAS breaks the link between throughput and validator costs. Ethereum can increase blob capacity 10x, 100x, or more without requiring validators to run data centers. This preserves decentralization (anyone can still run a validator on consumer hardware) while enabling massive scaling.
The upgrade positions Ethereum to handle 100,000+ transactions per second across its Layer-2 ecosystem—approaching Visa-level throughput while maintaining blockchain properties.
Impact on Layer-2 Networks: The Real Winners
While Ethereum mainnet fees dropping to $0.31 makes headlines, the bigger story is Layer-2 revolution. Networks like Arbitrum, Optimism, Polygon zkEVM, and zkSync process transactions off-chain then post compressed data to Ethereum as “blobs.”
Pre-Fusaka L2 Economics: Even after Dencun’s blob introduction, Layer-2s faced capacity constraints. During peak usage, blob space would fill up, creating fee pressure. Additionally, the near-zero blob fees during quiet periods created concerns about sustainable economics.
Post-Fusaka L2 Economics: With blob target increasing from 6 to 14 and PeerDAS enabling future expansion to 32-56+ blobs, Layer-2s gain:
- Abundant Capacity: No more blob space congestion, even during activity spikes
- Predictable Costs: Blob fee reserve system prevents wild swings, enabling better business planning
- Sustainable Scaling: Clear path to 10x-100x more capacity as ecosystem grows
Analysts project Layer-2 fees could stabilize around $0.005-0.01 for typical transactions, with complex DeFi operations costing lower. This makes Ethereum-secured blockchains genuinely competitive with alt-L1s on cost.
Can Ethereum Finally Compete With Solana?
The elephant in the room: Solana currently dominates DeFi, NFTs, and memecoin trading because transactions cost fractions of a cent and confirm in seconds. Ethereum lost massive market share in 2024-2025 as developers and users fled high fees.
The Bull Case for Ethereum’s Comeback:
Cost Gap Narrowing: $0.005-0.02 L2 fees vs. Solana’s $0.0001-0.001 represents a 5-20x difference—meaningful but not prohibitive for many use cases. When combined with Ethereum’s superior security, decentralization, and liquidity, some users will accept slightly higher costs.
Developer Familiarity: Ethereum’s EVM (Ethereum Virtual Machine) has vastly more developers than Solana’s Rust-based environment. If fees no longer exclude Ethereum, developers may prefer its mature tooling and extensive documentation.
Institutional Preference: Conservative capital (banks, asset managers, governments) gravitates toward Ethereum due to longer track record, larger validator set, and perception of stability. Solana’s periodic network outages (though rare in 2025) create hesitation among institutions.
Liquidity Network Effects: Ethereum hosts ~$62 billion in DeFi TVL versus Solana’s ~$10 billion. Deeper liquidity creates better pricing for traders, making Ethereum DeFi protocols more attractive despite slightly higher fees.
The Bear Case Against Ethereum:
Solana Isn’t Standing Still: While Ethereum improved, Solana’s Firedancer validator client launched in 2025, further improving performance. Solana can process 65,000+ TPS in bursts—an order of magnitude beyond Ethereum L2s even post-Fusaka.
User Experience Matters: Ethereum L2s require bridging, wallet configuration, and managing assets across multiple chains. Solana offers unified single-chain experience. For mainstream adoption, simplicity trumps marginal security improvements.
Momentum Shifts Are Hard to Reverse: Solana captured memecoin culture, NFT trading volume, and DeFi mindshare in 2024-2025. Developers built communities, launched projects, and accumulated users on Solana. Migrating back to Ethereum requires overcoming massive inertia.
The Likely Outcome: Coexistence
Rather than winner-takes-all, the market is pricing in multi-chain future:
- Ethereum dominates high-value DeFi (lending, derivatives, institutional assets) where security justifies slightly higher costs
- Solana captures high-frequency trading, gaming, social apps, and consumer crypto where UX and speed matter most
- Ethereum L2s compete for middle ground—DeFi users wanting Ethereum security with Solana-like costs
Fusaka doesn’t guarantee Ethereum reclaims lost territory, but it stops the bleeding. Users no longer have clearcut cost reasons to avoid Ethereum entirely.
What’s Next: The 2026 Roadmap
Fusaka isn’t the end—it’s Phase 1 of multi-year scaling plan.
Immediate Next Steps (Q1 2026):
- Blob target increases to 14 (January 7, 2026)
- Further gas limit expansion toward 150M target
- Layer-2 protocols optimize for new blob economics
- Developer tooling updated for PeerDAS
Mid-Term (2026-2027):
- Verkle Trees implementation (more efficient state storage)
- Full Danksharding preparation (massive data availability expansion)
- EVM improvements reducing computational costs
- Potential 5x gas limit increase as Vitalik Buterin suggested
Long-Term Vision (2027+):
- 100,000+ TPS across L2 ecosystem
- Sub-$0.001 fees for most transactions
- Native account abstraction making wallets user-friendly
- Cross-L2 interoperability feeling like single unified network
The target: Ethereum matching or exceeding Solana on cost and speed while maintaining superior decentralization and security. Whether achievable remains speculative, but the roadmap is clear.
Conclusion: Ethereum’s Fee Problem Is (Mostly) Solved
After years of complaints about $30 transactions and bleeding users to cheaper chains, Ethereum finally delivered on scaling promises. The Fusaka upgrade pushed average fees to $0.31 on mainnet and potentially under $0.01 on Layer-2s—a 95%+ reduction from 2024 peaks and close enough to Solana’s costs that differences no longer dominate user decisions.
This doesn’t guarantee Ethereum reclaims market share from Solana or becomes the default blockchain for all applications. User experience, developer communities, and network effects matter as much as transaction costs. But Fusaka removes Ethereum’s most glaring weakness, giving it fighting chance to compete.
For users who left Ethereum due to fees, the door is open to return. For developers who wrote off Ethereum as too expensive, it’s worth reconsidering. And for the Ethereum community that endured years of criticism while waiting for technical solutions, vindication feels sweet.
The real test comes in Q1-Q2 2026. Will users and capital flow back to Ethereum now that fees no longer exclude them? Or has Solana’s 2024-2025 momentum created irreversible network effects? The next six months will tell us whether Fusaka saved Ethereum’s relevance—or merely slowed its decline.
