Solana Foundation launched onchain governance Wednesday, moving protocol-level decisions into a stake-weighted voting system. The mechanism, called Solana Governance Proposals (SGPs), is fully onchain and verified by Merkle proof, according to the Foundation's announcement.
Validators can now propose and vote directly on protocol changes. The stake-weighted structure means voting power ties to the amount of SOL a validator operates, a standard approach in proof-of-stake networks but one that has historically concentrated decision-making among the largest operators.
Merkle proof verification is the technical backbone here. Rather than storing every vote onchain—which would inflate computation and storage costs—the system uses cryptographic proofs to verify the integrity of the vote tally. This approach reduces overhead while keeping results auditable.
The shift marks a departure from Solana's earlier governance model, which relied more on Foundation guidance and community input through offchain channels. Moving validation decisions onchain makes the process more transparent and removes a single point of control, though it also means the network's largest stake holders gain formal voting authority over protocol direction.
No details were provided on quorum thresholds, voting timelines, or whether the Foundation retains veto power or its own voting stake in the system. Those operational specifics will shape how quickly governance can actually move and whether smaller validators can meaningfully influence protocol decisions.
