Where the specification lives

The specification and reference documentation for Subrealms live in bitcoinuniverseio/atomicals-and-arc-20 and are published at https://bitcoinuniverseio.github.io/atomicals-and-arc-20/. That site is the authority. This page exists so you can find it and compare it with the rest of the estate.

Bitcoin Universe indexes or implements it in bitcoinuniverseio/index-atomicals-nfts-and-realms.

Operational behaviour

Indexing

State is read from Configured Atomicals ElectrumX authoritative subrealm authority.

What must be true before any change is accepted: Mutations fail closed unless the subrealm resolver returns the verified winner at the exact live owner outpoint.

Confirmation

Settlement requires at least one confirmation by default; operators may configure 1-100.

Settlement requires at least 1 confirmation.

Reorganisation

Authoritative winner and outspend reconciliation preserve signed evidence across rollback.

Freshness

Every mutation rechecks the Bitcoin and Atomicals checkpoint; deployment readiness must enforce operator lag limits.
