Latched 1Sat Provenance for Basket 1sat (Withdrawn)
A developer building on 1Sat Ordinals needed a fast way to prove where a token tip came from without walking its whole history, but there were competing proposals for how to do that, and it was not clear which one to build against. This document was one such proposal, and it has been pulled in favor of a different, still-active standard.

Everything an assistant needs to answer questions about BRC-156 accurately, including what it depends on.
Summary
- Why
- There was a proposed fast, O(1) way to verify where a 1Sat Ordinals tip originated, but the specific hardened transfer path it depended on was never shipped, so the proposal no longer had a reason to exist as its own standard.
- What
- BRC-156 was a withdrawn standard that once defined an optional "latched" tip-to-origin provenance profile for 1Sat Ordinals held in basket `1sat`, now replaced by BRC-150.
- How
- Its normative content has been removed entirely, and the file exists only so old links resolve; anyone implementing tip provenance should read BRC-150 for the transfer logic and BRC-147 for basket custody instead.
What this lets you do
- Recognize BRC-156 as retired and inactive
- Redirect any BRC-156 reference to BRC-150 for provenance logic
- Redirect any BRC-156 reference to BRC-147 for basket custody
- Avoid building against the abandoned latched v3 profile

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This standard has been withdrawn and its normative content removed.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.
BRC number 156 is retired and will not be reassigned. This file remains only so that existing references resolve.
