What happened
The full text of H. R. 8957, the Strategic Bitcoin Reserve bill, was officially published Monday, Bitcoin Magazine reported, citing the filing.
The draft does two things that hadn't been spelled out in earlier summaries. First, it imposes a 20-year lock-up on any bitcoin held by the federal government, blocking sales for two decades. Second, it requires quarterly proof-of-reserve attestations, forcing whichever agency takes custody to publish on-chain or auditor-verified holdings on a fixed cadence.
The bill's author, per Bitcoin Magazine's Micah Zimmerman, frames the lock-up as a deliberate signal that the reserve is strategic, not opportunistic. The text does not, in this draft, settle which agency holds custody, how seized BTC currently sitting with the U. S.
Marshals Service folds in, or how acquisitions beyond seized coins would be funded. Those are the open questions a markup will have to resolve.
Why it matters
Until Monday, the Strategic Bitcoin Reserve concept lived mostly as a Trump campaign talking point and a Senator Lummis framework. The H. R.
8957 text changes that. It's a real bill, with real mechanics, that a committee can now mark up. The 20-year lock-up matters because it removes the single largest structural overhang on bitcoin's supply picture: the periodic risk that Treasury auctions off seized BTC.
That risk has weighed on market structure every time the Marshals Service has scheduled a sale. Lock it up for two decades and that supply event disappears from the calendar. The proof-of-reserve clause is the other half.
