SEC Staff Accounting Bulletin 121 is a specific Institutions coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: The 2022 SEC staff accounting guidance for entities safeguarding crypto assets, influential in U.S. custody economics and later policy debate. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
SEC Staff Accounting Bulletin 121 is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
SEC Staff Accounting Bulletin 121 belongs to the documented history and social layer around Bitcoin. Primary records can establish what was published, built or decided; motives, influence and later interpretation should remain separate from those verifiable facts.
Understanding SEC Staff Accounting Bulletin 121 helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: SEC Staff Accounting Bulletin 121 introduced staff guidance in 2022 for safeguarding obligations involving platform users' crypto-assets; SAB 122 rescinded that guidance effective 30 January 2025. They should be verified before using the coordinate in analysis.
The practical limit is: SAB 121 is no longer current SEC staff guidance and was never a Commission rule; current accounting applies relevant contingency standards and disclosure requirements described in SAB 122. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
