PROOF Act
Key: what the circles and colors mean
Each circle is a bill. The ring fills as it moves through Congress:
Under the number: the Yea · Nay count of its final (or latest) recorded vote. On a member's page, the small badge is how that member voted: Y Yea / Aye, N Nay / No, P Present, – Not voting.
Gold and violet are only for Yea and Nay; they never mean a party. A member's party is the letter on their photo.
Not yet voted on. This bill is still a proposal: it hasn't reached a floor vote, and its text can change in committee or on the floor before any vote.

Proving Reserves Of Others’ Funds Act or the PROOF Act
This bill requires digital exchanges to protect customer funds and provide proof of reserves.
Specifically, digital exchanges must minimize (1) customer risk of asset loss, and (2) delays experienced by a customer when accessing assets. With some exceptions, a customer’s assets must be separated from any other assets and may not be used to margin, secure, or guarantee a trade or account of a person other than the customer.
Further, digital exchanges and digital custodians must report on their proof of reserves through an attestation from an independent auditing firm or a disinterested third party. The Office of Domestic Finance in the Department of the Treasury must make these attestations publicly available.
The bill also provides for the creation of an industry standard for the attestations.
Violations are subject to civil penalties.
