Solana Approves SIMD-0550 to Double Disinflation in Historic Governance Vote

Solana approved proposal SIMD-0550 in its first binding on-chain governance vote, doubling the network's annual disinflation rate from 15% to 30%. The accelerated schedule is estimated to shave roughly 18.9 million SOL from projected token issuance over the next six years, representing approximately $1.5 billion at current prices. The proposal passed with a two-thirds majority in Epoch 1023 alongside companion measures that established a network constitutional framework and a transaction fee-burn mechanism. Infrastructure firm Helius voted its full 16.05 million SOL stake in favor of the measure, while staking provider Figment cast approximately 17.07 million SOL against it. Custodial exchange Kraken drew criticism from Helius leadership after failing to cast a vote with its delegated token holdings before the governance window closed.
