Dr. Pavel Kravchenko proposes a protocol that would allow for anonymous cryptocurrency transactions while still enforcing know-your-customer (KYC) regulations. The protocol uses unlinkable proofs of identity attached to transactions and decentralized identity verification. It would allow multiple independent "groups" to set their own KYC policies while maintaining user privacy and control over private keys and identity. The goal is to create a global cryptocurrency network where users are subject to KYC but able to transact anonymously.

- 1. Anonymous identity on the blockchain Dr. Pavel Kravchenko Tembusu Systems
- 2. About me PhD in information security Chief cryptographer at Tembusu Systems Created an open-source academic course about cryptocurrencies
- 3. Electronic money = no privacy
- 6. REGULATION
- 7. Does identification mean traceability? Can user anonymously store identity in the blockchain? Where KYC info should be stored? Can we keep regulators accountable?
- 8. A crypto-currency protocol 1. That enforces that all participants passed KYC 2. While transaction are still anonymous 3. It is decentralized – no central authority 4. Impossible to link transactions of the same user 5. Audit might be possible in case of the suspicious transaction
- 9. Is it for Bitcoin?
- 10. Solution overview 1. Unlinkable proof of identity is attached to each transaction 2. Stealth and one-time addresses are used 3. Decentralized identity verification 4. Revocation is possible 5. User controls private keys and identity
- 11. Many KYC environments (groups) Germany China USA Switzerland UK
- 12. Processing nodes add transactions that contain POI to the ledger
- 14. Features 1. Registration process in independent from the payment network 2. As many groups as you need 3. Group manager selects own KYC policies 4. Possible to build groups where privacy is absolute 5. Actions of group manager are auditable
- 16. Can it work with Bitcoin/Ethereum?
- 17. Group signature A Group signature scheme is a method for allowing a member of a group to anonymously sign a message on behalf of the group
- 18. Conclusion We are building a protocol/platform That allows to create a global crypto-money network Where users are subject to KYC But are able to transact anonymously
