Galaxy Research introduced a new proposal on April 17 called MESA (Multiple Election Stake-Weight Aggregation) to refine how validators vote on Solana's inflation rate. The goal is to create a more market-driven approach for determining future SOL emissions.
MESA introduces a weighted average system, allowing validators to vote on multiple deflation rates. This contrasts with the previous binary voting system that struggled to reach a consensus on specific parameters for reducing SOL inflation. The motivation stems from the community's agreement that SOL inflation should be reduced, but the binary system couldn't agree on specifics.
The proposal suggests maintaining a fixed terminal inflation rate of 1.5%. Solana's current inflation rate is approximately 4.6%, with a significant portion of the total supply staked. The MESA system aims to offer validators a range of 'yes' options with varying deflation rates, with the final rate determined by a weighted average if a quorum is reached.
