White Paper Modification & Version Control Manager
Detect material changes in crypto-asset white papers and manage NCA notification deadlines per MiCA Art. 12
Step 1: Load White Papers
Version History & Retention
Per Art. 12(9), all versions must remain publicly available for at least 10 years with warnings.
Load white papers to see version history.
MiCA Compliance Note
Implemented: Art. 12 — Modification of published white papers (detection of significant new factors, material mistakes, and inaccuracies; notification to the NCA at least 7 working days before publication; version history retention for 10 years)
Out of scope: Art. 6 — Content validation and mandatory white paper structure (this POC assumes the original white paper is already Art. 6 compliant and only detects changes)
Out of scope: Art. 8 — Actual NCA notification submission (this POC generates the letter but does not connect to NCA systems)
Out of scope: Art. 9 & 13 — White paper publication (Art. 9) and withdrawal rights (Art. 13) (not modelled in modification flow)
What This POC Does Not Implement
- ❌ Actual NCA API integration — Notification letter is generated but not actually submitted to competent authorities
- ❌ Digital signature validation — SHA-256 hash is calculated but not cryptographically signed
- ❌ Full white paper validation — Detects basic field changes but does not validate compliance with entire Annex I requirements
- ❌ Permanent version archive — Version history is simulated; in production, requires distributed storage for 10-year retention
- ❌ Multi-language support — Only handles single-language white papers
- ❌ Blockchain timestamp proof — Deadlines calculated locally without blockchain notarization
- ❌ Automatic detection of all material changes — Classification algorithm is heuristic and may miss context-dependent significance
Note on EU working days calculation: The 7 working day period excludes weekends (Saturday/Sunday) and EU public holidays (Jan 1, Easter, May 1, Ascension, Whit Monday, Dec 25-26). The actual calendar period will be longer depending on how many weekends and holidays fall within those working days.
