Double Disinflation

Greptile Summary This PR adds SGP-0002, a governance proposal asking Solana validators and delegators to endorse doubling the annual disinflation rate from 15% to 30%, which would accelerate the path to the 1.5% terminal inflation rate from ~5.7 years to ~2.8 years and reduce emissions by ~18.9M SOL over six years. - The proposal content — motivation, economic impact figures, and SIMD-0550 linkage — is clearly written, but three sections required by the template are absent: Rationale, Alternatives Considered, and the critically important Vote section (which must state the exact on-chain question and the For / Against / Abstain options). - The document also introduces two non-template section

Missing required Vote section The template and README both list the exact Vote question with its options as a mandatory element of every SGP document: "contains, at minimum: … the exact Vote question with its options." Without this section, validators and delegators have no formally stated question to vote on and no specified choices (e.g. For / Against / Abstain), which is a precondition for taking the proposal on-chain via svmgov. Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Missing required Rationale and Alternatives Considered sections The template lists both Rationale and Alternatives Considered as required sections. Rationale explains why this direction is right (trade-offs, precedent), and Alternatives Considered must include at minimum the status-quo ("do nothing") option. Neither is present in the current document. The Motivation section touches on why inflation reduction is wanted but does not substitute for a structured rationale or an explicit treatment of alternatives. Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Technical Sponsor / Financial Sponsor sections are not in the template The template does not include these two sections, and the README does not list them as required. Adding non-template sections is fine if intentional, but it's worth confirming they belong in the canonical structure — especially since both say "Not required for this SGP", which means they add text without substance. If these are intended as a pattern for all future SGPs, the template should be updated; otherwise they can be removed here to keep the document lean. Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Section name diverges from template: Related SIMDs and SGPs vs Relationship to SIMDs The template calls this section Relationship to SIMDs and instructs authors to state what technical work a "yes" vote would trigger. The current section name and framing reads more like a reference list than an explicit statement of the downstream SIMD work. Aligning the name and adding a sentence that says "a 'yes' vote on this SGP signals support for SIMD-0550 to be implemented and activated" would match the template's intent. Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Introduction I strongly support this proposal. This SGP-0002 combined with SGP-0003 is exactly what Solana needs to become economically sustainable and investable again. I have recently commented on SGP-0003 and I have reused some parts of my comments here because they are equally relevant for addressing the objections to this SGP-0002. Why lower issuance is better than higher yield I came across a theory, that inflation is just a tax on non-stakers. For stakers inflation is neutral or even good because it is compensated by higher rewards, motivates holders to stake, and the higher yield attracts more investment in SOL. So touching the economic model just for the sake of reducing inflation d
