Ethereum and Solana are considering changes that could sharply reduce their annual token inflation, aiming to slow the future growth of ETH and SOL supplies. Grayscale, a major digital asset investment firm, reported that proposed updates could make both cryptocurrencies scarcer if their respective communities approve and implement the measures.

AAPLEthereum and Solana review token supply models
Both Ethereum and Solana play crucial roles in the decentralized finance (DeFi) ecosystem, supporting applications for stablecoins and tokenized assets. Their native tokens, traded globally, function as digital commodities whose value responds to fluctuations in supply and demand.
Grayscale stated that current proposals on each network are designed to reduce how many new tokens enter the system each year. If adopted, the changes could bring Ethereum’s and Bitcoin‘s annual supply inflation rates down to about 0.4% by 2031, while Solana’s rate could decrease to 1.1% in the same period. These figures assume that no additional changes to token issuance or supply mechanics are made beyond the proposals.
Bitcoin is a well-known benchmark in the digital assets world for its strict supply schedule and low annual inflation, making it useful for comparison. Gold’s annual supply growth is estimated at 1.8%, and recent US consumer price index (CPI) inflation stands at 3.3%. Both figures exceed the projected inflation levels for ETH and SOL, highlighting the potential impact of these protocol updates.
| Asset | Projected Annual Inflation (2031) | Current Gold: 1.8%/US CPI: 3.3% |
|---|---|---|
| Ethereum (ETH) | 0.4% | Lower |
| Bitcoin (BTC) | 0.4% | Lower |
| Solana (SOL) | 1.1% | Lower |
| Gold | 1.8% | Reference |
| US CPI | 3.3% | Reference |
Grayscale emphasized that lower token issuance will not necessarily result in higher prices for ETH or SOL, since market demand remains a separate factor. The proposals, however, are aimed directly at reducing the future supply growth rates of both networks.
With the proposed changes, annual inflation for ETH and SOL could fall below both gold and US CPI levels, potentially altering the scarcity profile of these tokens over the next decade.
Possible impact on staking and network rewards
The proposed supply reductions are still under discussion in the Ethereum and Solana communities. Grayscale’s research indicated that Solana’s proposals currently seem to have broader support, which may increase their likelihood of being implemented.
Staking rewards on both networks rely partly on new token issuance. Therefore, lowering inflation rates would reduce the number of new tokens distributed to those who stake their assets to secure blockchain operations. This adjustment could affect the returns earned by staking participants, who may receive fewer tokens even if prices rise due to increased scarcity.
For those holding ETH and SOL without staking, reduced supply growth could potentially benefit them if markets respond to increased scarcity. However, stakers would need to reconsider their risk and reward calculations under the new reward rates.
Grayscale described the proposed Ethereum updates as technical in nature, particularly around changes to its staking model, and noted that the impact will depend on how each network’s community ultimately votes on the measures.
Final decisions rest with governance bodies on each network, which will determine whether the proposals are permanently introduced into protocol rules.
