Source of truth
| Question | What answers it |
|---|---|
| Which orders exist | Durable index-bitmap SQLite listings, revisions, funded offers, reservations, action requests, broadcast lineage, activity, and settlement observations |
| Who owns the asset | Authoritative first-valid Bitmap claim, live Ord location, Bitcoin Core prevout and outspend, and complete 29-protocol output inventory agreement |
| Whether a trade settled | Exact PSBT templates, wallet-authorized signatures, Bitcoin Core preflight and broadcast, confirmed buyer-owned Bitmap claim, and rollback-safe reconciliation |
| What the protocol state is | Configured index-bitmap executable Marketplace authority |
Indexer
Primary index
Configured index-bitmap executable Marketplace authority
Fallbacks
None. If the primary index cannot be read, this protocol has nothing to fall back to and the page says the read failed.
What a mutation must prove
Execution requires distinct read and execution credentials, a fresh Bitmap checkpoint, authoritative first-claim ownership, complete inventory, clean funding, immutable economics, and post-sign validation.
Freshness, confirmation, and reorg policy
| Policy | Value | What the registry states |
|---|---|---|
| Freshness enforced | No | Every mutation is bound to stable Bitmap, Ord, Bitcoin Core, and complete-inventory checkpoints; deployment readiness must enforce configured checkpoint age and lag limits. |
| Maximum index lag | not set | No numeric block-lag ceiling is configured for this protocol. |
| Maximum observation age | not set | No maximum age is configured for an observation used by a mutation. |
| Listing confirmations | not set | Settlement requires the exact confirmed Bitcoin transaction and the authoritative Bitmap claim indexed at a buyer-owned output at stable checkpoints. |
| Settlement confirmations | 1 | A trade is recorded as settled after 1 confirmation. |
| Automatic reorg reconciliation | Yes | The authority appends reorg observations, reopens or invalidates affected orders deterministically, and preserves funding, broadcast, settlement, and replacement lineage. |
Where else this protocol appears
The Bitcoin Universe registry records actions per product surface. Core is the main surface. The others are named here because a reader who cannot do something in Core may be able to do it in a sibling product.
