Rarity could soon no longer be the exclusive domain of bitcoin. According to projections published by Grayscale, the annual growth of Ethereum and Solana supply could fall below gold’s 1.8% by 2031. Indeed, several reforms are currently being debated, including EIP-8361 on Ethereum and SIMD-0550 and SIMD-0553 on Solana. If adopted, ETH’s annual inflation could drop to 0.4%, compared to 1.1% for SOL. This development is likely to reshuffle the cards between rarity, staking yield, and valuation of these two cryptos.
On August 4th, six researchers from the ecosystem, including Justin Drake of the Ethereum Foundation, formally submitted proposal EIP-8361, entitled “Tapered Issuance Burn”. This text aims to fix what the authors call artificial overissuance in the current economic model of the network. Today, validators can still claim a staking yield close to 1.5% per year, even in a scenario where almost all ETH tokens would be locked in the protocol.
According to the diagnosis made by the researchers, this ceiling maintains excessive monetary creation without this corresponding to a real need for operational security. EIP-8361 thus introduces a dynamic mechanism designed to burn an increasingly large share of rewards as the ratio of staked ETH increases, planning a transition over 18 months to burn all rewards once about 60.25 million ETH, or half of the total supply, will be staked.
According to the quantitative models integrated in the proposal and analyzed by Grayscale, Ethereum’s annual issuance would peak around 0.5% at a staking level of 20%, before starting a downward trajectory towards zero as the network approaches the 50% plateau. In its central scenario projected for 2031, the asset manager estimates that ETH’s annual inflation would fall to about 0.4%, thus matching the emission rate anticipated for bitcoin over the same period.
This structural change does not go unnoticed by the institutional financial sector. Grayscale also recalls that its own ETHE spot fund began earlier this year distributing staking yields to its shareholders, constituting the first crypto spot exchange-traded product (ETP) in the United States to implement such a mechanism.
Several fundamental numerical indicators summarize the technical and financial impact of this update for the Ethereum network :
On its side, Solana follows a separate disinflationary trajectory, centered on improvement documents SIMD-0550 and SIMD-0553. Currently set at about 3.695% per year, this crypto’s inflation rate follows an initial schedule predicting a 15% reduction per year until reaching a long-term floor set at 1.5%. The SIMD-0550 project proposes to accelerate this process by doubling the annual reduction rate, compressing several years of gradual monetary adjustment into a much shorter time frame.
In parallel, the SIMD-0553 proposal modifies transaction fee management to increase the proportion of SOL permanently destroyed, preventing these cryptos from being re-injected to validators. However, Grayscale’s analysis shows that the additional amount of SOL burned via SIMD-0553 remains modest compared to the daily issuance volume under current network conditions, confirming that SIMD-0550 is the real driver of the projected drop to 1.1% by 2031.
This dual technical initiative does not enjoy a fully homogeneous consensus regarding its time feasibility. As Grayscale’s research note explicitly points out, these emission trajectories rely on strict assumptions of immediate implementation without alteration of other operational parameters, a condition considered unlikely to be realized exactly as such in reality.
The political and community dimension plays a key role here. In a recent intervention, Zach Pandl, Grayscale’s research director, qualified the comparative progress of the two networks. He then stated: “Solana’s plan enjoys broader community support and has better chances of being implemented than its Ethereum equivalent”. This divergence in the degree of buy-in from key players proves decisive for investors seeking to incorporate this future rarity in their valuation models.

Although mathematical models anticipate a marked compression of token creation, moving from proposal to effective implementation requires the buy-in of the majority of validation actors.
The difference in support highlighted by Grayscale between Ethereum and Solana illustrates how political and economic considerations influence the adoption of technical updates. On the market side, establishing rarity greater than that of gold marks a stage in the structuring of major altcoins as mature financial assets, capable of competing with traditional safe havens against global inflationary pressures.
Economically, the shift toward algorithmic enhanced rarity imposes a complex trade-off between the unit value of the asset and the gross yield perceived by network participants. By reducing the pace of new token issuance, these reforms de facto decrease nominal income paid to validators and holders of staked crypto ETF shares.
Zach Pandl notes, however, that a smaller circulating supply could support token prices in the market, thus offsetting the mechanical decrease in staking yields. The final equation will depend on the ecosystems’ ability to maintain the security of their consensus while convincing staking actors to accept lower direct rewards in exchange for a theoretically rarer and more robust underlying asset against traditional monetary pressures.
