The SIP Registry Is Live
The Bitcoin Stamps Improvement Proposal registry is now published on bitcoinstamps.xyz. It's the canonical, versioned home for how the Bitcoin Stamps protocol changes, and it's public for anyone to read.
What a SIP is
A SIP is a Bitcoin Stamps Improvement Proposal. It's a written spec for a change to the protocol: what it does, why it's needed, how it encodes, and which block activates it. SIPs are how the community turns an idea into a consensus rule without back-room decisions.
The whitepaper described this governance framework in the abstract. The registry makes it concrete. Now every proposal has a number, a status, and a page you can point to.
What's published
The registry launches with 13 SIPs:
- SIP-0000, the process document that defines how SIPs work, running through SIP-0011.
- SIP-0110, Ordinals Provenance.
Together they cover the standards the protocol already runs on and the proposals shaping what comes next. Each entry lives on its own page so you can read the exact spec rather than a summary of it.
Why a registry matters
Governance you can't inspect isn't really governance. Putting the SIPs in one versioned place does a few things at once:
- Builders get a single source of truth for encoding and activation rules.
- New contributors can see the full history of decisions, not just the current state.
- Anyone can check that what an indexer does matches what a SIP says it should do.
That last point ties the registry back to the protocol's core habit: prove it against the chain, don't just claim it. A published SIP plus an open-source indexer means a rule can be read, run, and verified by the same person.
