CTF Written Submission

Memo to SEC Crypto Task Force

Nov. 17, 2025
  • Receipt-based cryptography is proposed as a solution to evidentiary gaps in current compliance regimes, enabling verifiable proof of non-events (e.g., no unauthorized access or wash trades).
  • The memo advocates for regulatory recognition of cryptographic proof-of-absence receipts as valid artifacts in SEC examinations and enforcement actions.
  • It recommends the SEC invite pilot submissions from market participants to demonstrate these cryptographic receipts in real-world compliance workflows (e.g., custody, trade surveillance).
