Latched 1Sat Provenance for Basket 1sat (Withdrawn)
Sometimes a standards document gets written, then the people behind it change plans and stop building what it described. If nothing marks that document as dead, other developers can still find it, assume it works, and build against something that was never finished or safe to use. This document exists to stop that from happening by pointing everyone to the real, working approach instead.

Everything an assistant needs to answer questions about BRC-156 accurately, including what it depends on.
Summary
- Why
- Developers need a clear signal when a published standard has been abandoned, so they do not build against a design that was never finished or made safe.
- What
- BRC-156 is a withdrawn, content-free standard that formerly defined a faster "latched" way to prove where a 1Sat Ordinal came from, now replaced entirely by BRC-150.
- How
- The document keeps its number and URL so old links still resolve, but tells implementers to use BRC-150 for provenance and BRC-147 for basket custody instead, and explicitly forbids creating or trusting the old "latch" outputs or markers.
What this lets you do
- Recognize BRC-156 as withdrawn and non-normative
- Redirect any BRC-156 reference to BRC-150 for tip-to-origin provenance
- Reject latch outputs, latch markers, or v3 provenance objects as proof of anything
- Confirm basket custody rules still come from BRC-147

The specification
Withdrawal notice
This standard has been withdrawn and its normative content removed. It defined an optional latched transfer profile (v3 provenance, O(1) verification) for 1Sat Ordinals tips held in basket 1sat.
The author withdrew it because HandCash is not shipping the hardened Commit/Settle path that made the profile distinct; soft-latch tip naming alone did not justify a separate standard.
Interoperable tip→origin provenance is BRC-150 — 1Sat Provenance Remittance for Basket 1sat. Implementations that referenced this document should read BRC-150 instead. Basket custody remains BRC-147.
For implementers
- Wallets MUST NOT create latch outputs, latch markers or v3 provenance objects described by earlier revisions of this document.
- Wallets MUST NOT treat any of them as proof of origin. BRC-150 defines only v2, and treats any other version as non-conforming.
- Specifications MUST NOT cite this document as a way to follow an object's lineage. Cite BRC-150.
