What is Ultra Sound Money?

Ultra Sound Money is a concept that emerged in the Ethereum community to describe Ether (ETH) as an asset that is designed to become more scarce over time, thereby increasing its value. It is a play on the term "sound money," which refers to an asset with a stable or predictable supply, such as gold or Bitcoin, which is often seen as a store of value due to its limited supply. By calling ETH "Ultra Sound Money," proponents argue that it could be even more valuable than traditional sound money due to its deflationary characteristics.

The term gained popularity after the implementation of EIP-1559, a major upgrade to the Ethereum network in 2021. This proposal introduced a mechanism to burn a portion of the transaction fees (known as the base fee) whenever a transaction is processed on the network. By burning these fees, ETH is permanently removed from circulation, reducing the overall supply. If the amount of ETH burned exceeds the amount being issued as block rewards, the total supply of ETH can become deflationary, meaning it decreases over time. This deflationary mechanism contrasts with traditional fiat currencies, which are inflationary and lose purchasing power over time due to overprinting and monetary policy.

Another significant development for Ethereum's "Ultra Sound Money" narrative is the introduction of  Ethereum Improvement Proposal (EIP) 4844 that implemented blobs, enabling more efficient posting from Layer 2 (L2) solutions. As a result, much of the network activity has shifted to L2s, where transactions are processed more efficiently and with lower fees. This migration has somewhat muted the Ultra Sound Money narrative, as fewer transactions on the Ethereum mainnet mean fewer fees are being burned. However, it has also made Ethereum much more usable for high-value transactions, while lower-value transactions have increasingly moved to L2s, which are optimized for scalability and cost efficiency.

The term Ultra Sound Money also emphasizes the future-proof nature of ETH, especially after Ethereum's transition to Proof of Stake (PoS). Under PoS, ETH holders can stake their tokens to help secure the network and earn rewards, but the issuance of new ETH is much lower compared to the previous Proof of Work (PoW) model. This reduction in new issuance, combined with the burning of transaction fees, positions ETH as a potentially deflationary asset that could grow in value as demand increases and supply tightens.

The Ultra Sound Money narrative supports the idea that Ethereum can serve as a reliable store of value, similar to Bitcoin, but with added utility as a platform for decentralized applications and finance (DeFi). By reducing the supply of ETH and creating scarcity, Ethereum aims to provide a robust economic model where ETH is not only the fuel for the network but also a valuable asset in its own right.
