Ethereum and Solana Cut Staking Yields Amid Grayscale ETF Changes

Ethereum and Solana are proposing changes to their staking mechanisms in response to Grayscale's plans to convert staking rewards into cash for shareholders. The proposed changes would reduce the native rate of return on staked assets, which could have significant implications for investors.

Solana's proposal, SIMD-0550, would accelerate disinflation and cut the modeled staking yield from 5.84% to 2.25% within three years. This change is expected to reduce the number of SOL issued over six years by 18.9 million, worth around $1.47 billion at current prices.

Ethereum's proposal, EIP-8363, would burn an increasing share of validator issuance as staking rises, with a 100% consensus-reward burn once about half of ETH's supply is staked. This change aims to slow or remove validator-reward issuance as staking grows, potentially discouraging excessive validator growth.
