Ethereum’s Ultrasound Money Narrative: Still True or Fading?

When Ethereum transitioned to Proof-of-Stake and introduced EIP-1559, a bold new concept emerged: ultrasound money. It was more than just a playful jab at Bitcoin’s “sound money” ethos; it was a thesis rooted in real mechanics. ETH would burn with every transaction, issuance would plummet, and the network would evolve into a deflationary machine. For a time, the data backed it up: ETH supply shrank, burn rates soared, and the meme became a movement.

But in 2026, the landscape looks different. The Dencun upgrade slashed gas fees, Layer 2s absorbed much of the activity, and ETH’s net supply quietly began to rise again. So the question emerges: Is Ethereum still an ultrasound money or has the narrative outpaced the math? This piece examines the origins of the thesis, the mechanisms that drove it, and whether the data still supports the idea.

What Does “Ultrasound Money” Mean?

“Ultrasound money” refers to Ethereum’s shift toward deflationary economics, where the ETH supply can decrease over time, thereby enhancing its scarcity and store-of-value potential.

The term ultrasound money emerged as a tongue-in-cheek response to Bitcoin’s claim of being “sound money.” While Bitcoin has a fixed supply of 21 million coins, Ethereum’s supply was once considered inflationary and unpredictable. However, Ethereum’s developers introduced mechanisms that could make ETH even more scarce than Bitcoin, hence, “ultrasound.”

This meme evolved into a serious economic thesis: ETH could become a deflationary asset, meaning its total supply might shrink over time, increasing its value proposition as a store of wealth.

Ethereum’s transformation hinged on two major upgrades:

• EIP-1559 (London Hard Fork): Introduced in August 2021, this upgrade changed Ethereum’s fee structure. Instead of all transaction fees going to miners, a portion (called the base fee) is now burned, permanently removing ETH from circulation. This created a consistent deflationary pressure on the supply.
• The Merge (Proof-of-Stake Transition): In September 2022, Ethereum shifted from Proof-of-Work to Proof-of-Stake. This has drastically reduced ETH issuance by over 90%, as validators require far less energy and reward than miners. Combined with EIP-1559, this made ETH net-deflationary during periods of high network activity.

Before these upgrades, Ethereum’s supply grew steadily, with no hard cap. Post-Merge and EIP-1559, ETH’s supply dynamics changed dramatically:

• ETH burn rate often exceeds issuance, especially during periods of high gas fees.
• The net supply has decreased at times, with millions of ETH being burned since the implementation of EIP-1559.
• ETH’s inflation rate has dropped below Bitcoin’s, challenging BTC’s dominance as a store of value.

However, it’s worth noting that ETH’s deflationary status isn’t guaranteed. For example, after the 2024 Dencun upgrade, lower gas fees resulted in reduced burning, leading to slight inflation. Ethereum’s economic model is now defined by:

• Elastic scarcity: ETH supply adjusts based on network usage.
• Deflationary potential: ETH can become scarcer over time, particularly during periods of high demand.
• Utility-driven value: ETH isn’t just a store of value; it powers smart contracts, DeFi, NFTs, and more.

These mechanisms position Ethereum as a programmable, deflationary asset, a new breed of digital money that’s not just “sound,” but “ultrasound.”

The Mechanics Behind Ethereum’s Supply Shift

Ethereum’s journey from an inflationary asset to one with deflationary potential is rooted in a series of transformative protocol upgrades. These changes weren’t just technical; they redefined ETH’s economic behavior and its role as a store of value. At the heart of this evolution are mechanisms that reduce ETH issuance and introduce supply-burning features, creating a dynamic monetary policy that responds to network activity.

EIP-1559 and the Fee Burn Mechanism

Implemented in August 2021 as part of the London Hard Fork, EIP-1559 revolutionized Ethereum’s fee structure. Previously, all transaction fees were paid directly to miners. With EIP-1559, a base fee is now algorithmically set and burned, permanently removing ETH from circulation.

This means that every transaction contributes to reducing the total supply of ETH. The more the network is used, the more ETH is burned. This mechanism introduced a direct link between Ethereum’s utility and its deflationary pressure, making high activity periods economically impactful.

The Merge and Proof-of-Stake Transition

In September 2022, Ethereum transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS) through an upgrade known as The Merge. This shift drastically reduced ETH issuance by over 90%, as validators in PoS require far fewer rewards than energy-intensive miners.

The result was a significant drop in new ETH entering circulation. Additionally, PoS eliminated the constant sell pressure from miners who needed to liquidate ETH to cover operational costs. This not only improved Ethereum’s sustainability but also reinforced its deflationary tendencies when combined with EIP-1559’s burn mechanism.

Deflationary Pressure and Supply Dynamics

Ethereum’s supply is now governed by a balance of forces: staking, gas fees, and network activity. When gas fees are high, more ETH is burned, increasing deflationary pressure. Conversely, during periods of low activity or low fees, such as after the Dencun upgrade, ETH burning slows, and the network may experience slight inflation. Staking also plays a role: ETH locked in validators is temporarily removed from circulation, reducing liquid supply.

These dynamics create an elastic monetary policy, where Ethereum’s inflation or deflation rate adjusts in real-time based on usage, making ETH a uniquely responsive digital asset.

The Triple Halving Effect

Ethereum’s transition to Proof-of-Stake (PoS) in 2022 not only changed its consensus mechanism but also redefined its monetary policy. One of the most striking outcomes of The Merge was a dramatic reduction in ETH issuance, which dropped by approximately 90%. This reduction is often referred to as the “Triple Halving,” drawing a direct comparison to Bitcoin’s well-known halving events.

Bitcoin undergoes a halving roughly every four years, reducing the block reward by 50% each time. This slows the rate of new BTC entering circulation and is central to Bitcoin’s deflationary design. Historically, each halving has been associated with increased scarcity and bullish price action, resulting from reduced sell pressure from miners.

• 1st Halving (2012): 50 → 25 BTC per block
• 2nd Halving (2016): 25 → 12.5 BTC
• 3rd Halving (2020): 12.5 → 6.25 BTC
• Each halving = ~50% issuance reduction

When Ethereum switched to PoS, its issuance dropped from ~13,000 ETH/day to ~1,600 ETH/day, a reduction of over 88%. This is equivalent to three consecutive Bitcoin halvings occurring simultaneously.

Metric	Bitcoin Halving	Ethereum Merge
Issuance Reduction	~50% per halving	~90% total
Sell Pressure Impact	Gradual	Immediate
Frequency	Every ~4 years	One-time shift
Supply Dynamics	Fixed cap	Elastic, burn-adjusted

This “Triple Halving” effect is a cornerstone of the ultrasound money thesis, which argues that Ethereum’s new economic model, combining drastically reduced issuance with EIP-1559’s burn mechanism, makes ETH potentially more scarce than Bitcoin.

With ETH issuance slashed and burn mechanisms in place, Ethereum can now experience net-negative inflation during periods of high activity. This means the total ETH supply can shrink over time, especially when gas fees spike. Unlike Bitcoin’s fixed schedule, Ethereum’s deflationary pressure is usage-driven, making it a more dynamic and responsive monetary system.

Ultrasound Money vs. Sound Money: Key Differences

Ethereum and Bitcoin represent two distinct philosophies of digital scarcity. Bitcoin is often described as “sound money” due to its fixed supply and predictable issuance schedule. Ethereum, on the other hand, has evolved into what its community calls “ultrasound money,” a dynamic, deflationary model driven by network activity and protocol upgrades. Here is a clear breakdown of how they differ:

Feature	Bitcoin: Sound Money	Ethereum: Ultrasound Money
Supply Cap	Fixed at 21 million BTC	No hard cap; supply adjusts dynamically
Issuance Mechanism	Block rewards via Proof-of-Work	Validator rewards via Proof-of-Stake
Issuance Schedule	Halves every ~4 years	Reduced ~90% instantly via The Merge
Deflationary Pressure	Gradual via halvings	Immediate via fee burns (EIP-1559)
Fee Structure	All fees go to miners	Base fees are burned; tips go to validators
Sell Pressure	High (miners sell to cover costs)	Lower (validators have minimal overhead)
Scarcity Model	Predictable, fixed	Adaptive, usage-driven
Economic Identity	Digital gold, store of value	Programmable money with deflationary potential

Bitcoin’s sound money thesis is rooted in monetary orthodoxy, characterized by a fixed supply, predictable issuance, and resistance to change. It is designed to be simple, secure, and scarce. Ethereum’s ultrasound money thesis emphasizes flexibility: it adapts to network demand, burns supply during periods of high usage, and evolves through upgrades. It’s designed to be programmable, sustainable, and deflationary.

Ethereum’s model doesn’t just mimic scarcity; it reacts to activity, making ETH more scarce when demand is high. This elasticity is what sets ultrasound money apart.

Is the Ultrasound Money Narrative Still Holding Up for Ethereum?

Ethereum’s post-Merge economic model was hailed for its deflationary potential; however, recent data suggests that the narrative is shifting. While ETH once experienced net-negative issuance, several factors have reversed that trend.

• Burn Metrics Are Down: Base fee burns from EIP-1559 have slowed, primarily due to lower on-chain activity and the rise of Layer 2 scaling solutions, such as Optimism and Arbitrum. These L2s reduce gas fees on the Ethereum mainnet, which in turn lowers the amount of ETH burned per transaction. As a result, Ethereum’s inflation rate rose to 0.74% in late 2024, the highest in two years.
• Net Supply is Increasing: Despite its deflationary design, Ethereum’s total supply has grown by 0.62 million ETH over the past year. This uptick reflects a mismatch between issuance and burn, especially during periods of low network congestion.
• Staking Trends & Sell Pressure: ETH staking remains strong, with a large portion of supply locked in validators. However, staking alone doesn’t offset inflation if burn rates are low. Validators have less sell pressure than miners, but the issuance still adds to the circulating supply.

Ethereum’s monetary identity is shifting from “ultrasound money” to something more nuanced. The ETH supply expands or contracts based on usage, rather than following a fixed schedule. Ethereum’s monetary policy can evolve through upgrades like EIP-4844 and future adjustments to the fee market. ETH remains essential for gas, staking, and DeFi, even if it’s not deflationary.

While the “ultrasound money” meme helped frame Ethereum’s post-Merge economics, its long-term narrative may pivot toward adaptive monetary design. This model reflects real-time network dynamics rather than rigid scarcity.

How Investors Interpret the Ultrasound Money Narrative

The phrase “ultrasound money” was coined as a tongue-in-cheek response to Bitcoin’s “sound money” ethos. Ethereum advocates used bat and sound emojis to playfully suggest that ETH could become even more scarce than BTC. However, as Ethereum implemented EIP-1559 and transitioned to Proof-of-Stake, the meme gained serious traction, symbolizing Ethereum’s shift toward deflationary economics and adaptive scarcity.

This meme evolved into a thesis: Ethereum’s monetary policy is not only deflationary but also programmable, aligning with its broader ethos of innovation and flexibility.

Cultural Spread Across Crypto Communities

Ethereum supporters on platforms like X (formerly Twitter) began using bat and sound emojis in their profiles, signaling their allegiance to the “ultrasound money” thesis. Movements like “Make ETH Ultrasound Again” gained momentum in 2025, particularly as burn rates fluctuated following Dencun. Influencers, DAOs, and crypto educators utilized the meme to explain Ethereum’s economic model in simple, engaging terms, bridging technical upgrades with investor psychology.

Investor Sentiment & Strategic Implications

Investors interpreted the surge in ETH’s value as a signal of its potential to become a store of value, especially during periods of high burn and low issuance. Burn dashboards and staking trends became key indicators for ETH’s monetary health. Traders closely monitored these developments to assess deflationary pressure and potential price movements. Even as ETH’s inflation returned post-Dencun, many investors still viewed ultrasound money as a symbol of Ethereum’s ability to evolve and optimize its economics.

Shaping Ethereum’s Broader Identity

Ultrasound money isn’t just about supply; it reflects Ethereum’s philosophy of innovation, adaptability, and community-driven evolution. It helped unify diverse stakeholders, including developers, investors, and users, around a shared vision of Ethereum as a sustainable, programmable financial layer. Even as ETH’s supply trends shift, the ultrasound money meme continues to influence how Ethereum is marketed, understood, and valued.

Summing Things Up

Ethereum’s evolution from an inflationary beginning to a deflationary, adaptive asset has reshaped its identity within the crypto ecosystem. Through upgrades like EIP-1559 and The Merge, ETH transformed into a dynamic form of digital money, one that burns supply, reduces issuance, and responds to real-time network activity. While the “ultrasound money” thesis may be evolving, it remains a powerful symbol of Ethereum’s commitment to innovation, sustainability, and economic experimentation.

FAQs (Frequently Asked Questions)

Q: What does “deflationary ETH” actually mean for holders?

A: Deflationary ETH means the total supply of Ethereum can shrink over time, especially during periods of high network activity. For holders, this implies increased scarcity, which may enhance the long-term value of ETH. It also signals a shift from inflationary issuance to a burn-driven model, where usage itself reduces supply. This dynamic strengthens ETH’s appeal as a store of value and hedge against dilution.

Q: Can Ethereum become inflationary again, and why?

A: Yes, Ethereum can become inflationary again, especially during periods of low network activity and low gas fees. When fewer transactions occur, less ETH is burned via EIP-1559, while validator rewards continue to add new ETH to the supply. If burn rates fall below issuance, the net supply increases, which can lead to inflation. This elasticity is built into Ethereum’s adaptive monetary design.

Q: Why do Bitcoiners reject the “ultrasound money” idea?

A: Bitcoiners often reject the “ultrasound money” idea because it contrasts with Bitcoin’s core principle of fixed supply and immutability. They view Ethereum’s adaptive monetary policy, based on fee burns and protocol upgrades, as unpredictable and centralized. Bitcoin’s credibility stems from its simplicity and resistance to change, while some see Ethereum’s flexibility as a risk to long-term monetary integrity.

Q: How do I track Ethereum’s supply, burn rate, and issuance in real time?

A: You can track Ethereum’s supply, burn rate, and issuance in real time using dashboards like ultrasound.money, etherchain.org, and Etherscan’s ETH supply tracker. These platforms show live metrics on ETH burned via EIP-1559, validator rewards, and net supply changes. They are essential tools for monitoring Ethereum’s monetary dynamics and evaluating its deflationary status.

Q: Does lower gas fees or Layer 2 scaling hurt the ultrasound money thesis?

A: Yes, lower gas fees and Layer 2 scaling can reduce the amount of ETH burned via EIP-1559, weakening the deflationary pressure that underpins the ultrasound money thesis. As more activity shifts off-chain, mainnet burn rates decline, potentially leading to net ETH inflation. While this challenges the original narrative, it also highlights Ethereum’s evolving focus on scalability and utility, rather than strict scarcity.
