The idea of Ethereum as "ultra-sound money"—a deflationary asset strengthened by transaction fee burning—has been a cornerstone of its economic narrative since the Merge. However, recent shifts following the Dencun upgrade have sparked debate: Is it time to let go of this concept? And more importantly, would that actually be a bad thing?
As L2 networks grow and blob transactions drastically reduce on-chain costs, Ethereum’s deflationary mechanics are under pressure. Some analysts now suggest that ETH may have entered an inflationary phase again, challenging its ultra-sound status. This article explores whether the "ultra-sound money" narrative still holds value—and what it means for Ethereum's future.
Understanding Ultra-Sound Money
At its core, ultra-sound money refers to an asset designed not just to resist inflation but to become scarcer over time. For Ethereum, this scarcity was expected to come from EIP-1559, which burns a portion of every transaction fee. When more ETH is burned than issued as block rewards, the total supply decreases—creating deflation.
This mechanism, combined with staking and supply constraints, led many to believe Ethereum could evolve into a stronger store of value than even Bitcoin.
But Dencun changed the game.

The Impact of Dencun and Blob Transactions
The Dencun upgrade introduced blob-carrying transactions, allowing Layer 2 (L2) rollups to post data to Ethereum at a fraction of previous costs—up to 10x cheaper in some cases. While this dramatically improves scalability and user experience, it also reduces the amount of ETH burned per transaction.
As a result:
- Network activity has shifted from L1 to L2.
- Transaction volume on L2s has surged, yet cost to Ethereum remains flat.
- ETH burn rates have dropped to some of their lowest levels since the Merge.
CryptoQuant data shows that Ethereum is now potentially inflationary again, undermining the ultra-sound thesis.
But here's the twist: this might not be a flaw—it could be progress.
The Rise of Dominant L2 Ecosystems
One of the most significant trends post-Dencun is the emergence of power-law dynamics among L2s. A few dominant chains—like Base, Arbitrum, and Optimism—are capturing disproportionate market share.
Take Base as an example over the past 90 days:
- Transaction volume ↑ ~75%
- Throughput ↑ ~100%
- Cost paid to Ethereum ≈ unchanged
This means these L2s can scale infinitely without increasing pressure on Ethereum’s fee market—or contributing meaningfully to ETH burns.
They act like black holes for users, absorbing activity across the ecosystem while leaving the underlying economic engine (fee burning) largely untouched.
So while Ethereum secures these chains and enables their operation, it doesn’t directly benefit from their growth in terms of tokenomics.
A Shift in Ethereum’s Role?
Could Ethereum be evolving from a user-facing chain into a settlement and security layer?
If so, constant deflation might not be ideal. Mild inflation—or even neutrality—could support broader adoption by ensuring sufficient liquidity across ecosystems.
Consider this:
- Deflation encourages hoarding, which can reduce circulation and stifle usage.
- Bitcoin’s fixed supply makes it excellent for scarcity but limits utility in dynamic economies.
- Ethereum, by contrast, could prioritize ecosystem health over artificial scarcity.
In other words, if ETH powers thousands of applications through scalable L2s, does it matter if it’s technically "ultra-sound"?
Not necessarily. What matters is whether the network remains secure, decentralized, and capable of supporting global-scale applications.

Core Keywords Integration
Throughout this discussion, several key concepts emerge:
- Ultra-sound money: The original vision of ETH becoming deflationary through fee burns.
- Ethereum scalability: Achieved via Dencun and blob transactions.
- Layer 2 dominance: Power-law distribution where top L2s absorb most users.
- ETH burn rate: Now declining due to reduced L1 activity.
- Modular blockchain architecture: Separating execution (L2) from consensus and data availability (L1).
- Ethereum tokenomics: The evolving balance between issuance and destruction.
- Blob transactions: Cost-efficient data posting enabling cheap L2 scaling.
- Network utilization: Low despite high L2 growth, due to fixed Ethereum costs.
These keywords reflect both technical developments and shifting market perceptions—essential for SEO visibility and reader engagement.
Frequently Asked Questions (FAQ)
Q: Is Ethereum still deflationary after Dencun?
As of mid-2025, Ethereum is likely not deflationary. With lower fee burns from blob transactions and reduced mainnet activity, new ETH issuance may exceed burns, resulting in mild inflation.
Q: Does the end of ultra-sound money mean ETH is less valuable?
Not necessarily. Value isn’t solely tied to scarcity. If Ethereum enables widespread adoption through scalable L2s, its utility—and thus market demand—can still grow significantly.
Q: Are L2s bad for Ethereum’s economy?
No. L2s expand Ethereum’s reach. However, they decouple usage from direct fee generation on L1. This calls for new economic models beyond simple burn-driven scarcity.
Q: Can Ethereum regain its deflationary status?
Yes—if future upgrades increase base fees, reintroduce higher-cost mechanisms for heavy users, or implement additional burn components. But this may conflict with usability goals.
Q: What should Ethereum developers focus on now?
Prioritizing modular scalability, improving L1-L2 interoperability, and exploring alternative value accrual mechanisms (e.g., protocol-owned liquidity, revenue sharing) may matter more than preserving ultra-sound rhetoric.
Q: Will ETFs affect the ultra-sound debate?
Absolutely. ETH ETFs bring institutional capital and shift focus from niche tokenomics to macro adoption. Once ETFs are live, debates about burn rates may seem secondary to broader market dynamics.
Final Thoughts: Letting Go of a Narrative
Abandoning the "ultra-sound money" label doesn’t mean abandoning Ethereum’s potential. It means acknowledging a new reality:
Ethereum’s strength lies not in artificial scarcity, but in becoming the foundational layer for a decentralized internet.
The modular future—where L2s handle execution and Ethereum ensures security—is working. Users are moving. Costs are falling. Adoption is rising.
Perhaps the real measure of success isn’t how much ETH we burn—but how much innovation we enable.
And in that light, Ethereum isn’t losing its soundness. It’s finding a deeper resonance.
