According to Wu, the Solana Foundation has officially launched its on-chain governance mechanism, Solana Governance Proposals (SGP). Validators can now use SGP to submit, support, and decide on core protocol decisions. All proposals are conducted on-chain, using a stake-weighted voting mechanism and verified through Merkle proofs. Any validator with at least 100,000 SOL delegated can initiate an SGP. Unlike Solana Improvement Documents (SIMD), which focus on technical and protocol changes, SGP is primarily for expressing ecosystem governance opinions. Proposals must gain at least 15% of total network stake support before entering the formal voting phase. https://www.(wublock123.com)/news/solana-onchain-governance-sgp-proposals-need-15pct-stake-63837
