Ethereum Ultrasound Money: Has L2 Scaling Broken the Model?

In the market, Ethereum (ETH) is classified as a decentralized smart contract platform under various international jurisdictions. Based on the data, Ethereum’s total circulating supply reached approximately 121.88 million ETH in mid-July 2026. In the market, Ethereum’s price underperformance relative to Bitcoin in 2026 is widely attributed to a structural shift in fee dynamics and on-chain flow. This point indicates that the transition to a Layer 2 (L2) centric scaling model has created an economic asymmetry where L2 sequencers extract massive profits while leaving the L1 base layer to bear the security costs on a shrinking burn rate, challenging the classic Ethereum ultrasound money thesis.

Fact Block: The Collapse of the Ethereum Ultrasound Money Burn Engine

Based on the data, the activation of EIP-4844 in March 2024 slashed L2 data-posting costs by over 90%, causing Ethereum’s daily burn rate to collapse from thousands of ETH to between 50 and 70 ETH. According to the announcement, the Fusaka upgrade went live on December 3, 2025, introducing EIP-7918 to establish a blob fee floor tied to L1 execution costs. Based on the data, this floor requires the blob base fee to be at least 1/15.258 of the L1 execution base fee, raising the minimum blob price to a range between 0.01 Gwei and 0.5 Gwei. According to the announcement, the subsequent Blob-Parameter-Only (BPO) forks on December 17, 2025, and January 7, 2026, successfully raised the target blob capacity from 6 to 14 per block. Based on the data, as of mid-July 2026, the total value locked (TVL) across L2 rollups reached approximately $35 billion, with Base accounting for $11 billion and Arbitrum at $10.4 billion.

This combination of cheap blob space and massive L2 transaction volume has compressed the L1 fee burn engine, resulting in a mild annual ETH supply inflation of 0.2% to 0.8% in 2026. This indicates that while L2 networks now process roughly 95% of all Ethereum ecosystem transactions, L2 sequencers retain the vast majority of user fees as profit while returning less than 1% to the L1 base layer as blob fees. In the market, critics argue that this economic model is parasitic, as L1 token holders subsidize L2 scaling without direct value accrual. This point indicates that the upcoming Glamsterdam upgrade, which cleared its final multi-client devnet hurdle on June 16, 2026, represents a major pivot to scale L1 directly by raising the gas limit from 60 million to 200 million. This combination of a 3.3x L1 gas limit expansion and parallel execution could reduce smart contract fees on L1 by an estimated 78%, potentially drawing high-value DeFi activity back to the main chain.

Uncertainty Block: Regulatory Pressures and Alternative Data Availability Layers

According to authorities, the legal status of ETH and its staking yield remains an unresolved and jurisdiction-dependent regulatory issue, which continues to impact institutional spot ETF inflows. In the market, there is no consensus on whether the 200 million gas limit in the Glamsterdam upgrade will successfully restore the ETH burn rate or simply lead to state bloat and validator centralization. Under this scenario, if L2 networks continue to migrate their data availability needs to cheaper alternative layers like Celestia, Ethereum’s L1 fee revenue could decline further regardless of internal protocol upgrades.

Watchpoint Block: Key Metrics for the Ethereum Ultrasound Money Model

If the Glamsterdam upgrade is successfully activated on the mainnet during the projected H2 2026 window, market participants must closely monitor the L1 gas price and the resulting daily ETH burn rate. In the case of the next scheduled BPO capacity adjustments in late 2026, the balance between L2 transaction margins and L1 blob fee burn will serve as the primary metric for evaluating the long-term viability of the “ultrasound money” thesis.
