Solana is preparing a network upgrade that would trim block time to 350 milliseconds from 400 milliseconds, a change aimed at lifting transaction speed and throughput. At the same time, validators are in a formal vote through Aug. 18 on companion tokenomics proposals that would reprice fees around compute units and accelerate the network's disinflation schedule. SIMD-0553 would replace the flat 5,000-lamport fee with a 2,500-lamport inclusion fee plus a resource fee based on compute units that is burned in full, which Temporal estimates could raise daily burns to 7,500-9,000 SOL from about 648 SOL. SIMD-0550 would double the annual disinflation rate to 30%, bringing Solana's 1.5% terminal inflation rate forward to 2029 from 2032, and together the measures are projected to lower net annual supply growth to about 1.05% by 2029.
