The end of ultra-sound money? How Dencun transformed the Ethereum economy

The Dencun upgrade on Ethereum has completely reshaped the narrative of ultra-sound money, which for years promised a deflationary future for ETH. What was once a clear vision of an “ultra-healthy” currency now faces technical challenges that force a rethink of the long-term viability of this model.

The Original Promise of Ultra-Sound Money

Ethereum’s ultra-sound money concept was based on the idea that the network could surpass traditional sound money, even compared to Bitcoin. The strategy was straightforward: through technical changes like EIP-1559 and The Merge, the goal was to gradually reduce ETH supply. After the Proof-of-Stake merge in 2022, this vision seemed on track, with the token even showing periods of supply deflation.

However, technical realities have proven more complex. Subsequent updates introduced variables that complicated the deflationary mechanism initially expected to be maintained.

Dencun: When Scaling Changes the Rules of the Game

The Dencun upgrade significantly altered the dynamics supporting the ultra-sound money narrative. By drastically reducing transaction costs and decreasing ETH consumption rate on the network, the update achieved more affordable fees for users, but at a cost: the decoupling of network activity from the token burn mechanism.

This separation has had a crucial impact. Now, even when the network experiences high activity, ETH burn does not increase proportionally. The result is that a dramatically higher level of network activity is required to sustain the deflation previously achievable. This has turned Ethereum back into an inflationary network, complicating the core argument that supported the promise of ultra-sound money.

The Current Dilemma

According to CryptoQuants data, this transformation has sparked a deep debate within the community. With a circulating supply of 120,692,268 ETH and a total supply of 120,693,508, the reality is that the network now faces a completely different dynamic from the initial premise.

Ultra-sound money promised a future where Ethereum would become an increasingly scarce currency. However, Dencun has shown that scalability goals and usability demands can conflict with deflationary mechanisms. The choice between low fees for users and sustained deflation presents a dilemma that currently has no clear solution within Ethereum’s technical horizon.
