A reverse blind trust using a Cashu Chaumian Mint and blinded signatures would be a decentralized financial arrangement that allows a trustor to manage assets without revealing ownership or transaction details. This setup leverages Chaumian e-cash protocols, ensuring privacy and anonymity while still allowing controlled spending or asset distribution.

How a Reverse Blind Trust Works:

1. Creation of the Trust Using a Cashu Chaumian Mint

• The trustor deposits funds or assets into a Chaumian Mint, which issues blinded tokens (e-cash) that represent the value held.

• These tokens are cryptographically signed using blinded signatures, meaning the mint cannot see the original request but can verify authenticity when spent.

2. Reverse Blind Mechanism (Trustor Controls Spending, but Remains Untraceable)

• Unlike a traditional blind trust, where the trustor has no control, here the trustor retains full control over spending but remains anonymous.

• The trustee (e.g., the mint operator) facilitates transactions but does not know the trustor’s identity or specific transactions due to blinded signatures.

3. Spending and Redemption Process

• When the trustor (or designated beneficiaries) want to withdraw or spend funds, they submit blinded e-cash tokens to the mint.

• The mint verifies and redeems the tokens without linking them to their origin, preserving full transaction privacy.

• The tokens can be used within a closed ecosystem or converted into standard currency.

Key Features & Benefits:

• Anonymity & Privacy: Trustor’s transactions are cryptographically hidden, ensuring financial privacy.

• Decentralized Trust Management: No reliance on traditional financial institutions or trustees.

• Controlled Spending: Unlike a traditional blind trust, the trustor can still dictate how funds are used without revealing their identity.

• Protection from Surveillance & Censorship: No centralized entity can track or block transactions.

• Security via Blinded Signatures: Ensures the mint cannot link issued e-cash to spending events.

Use Cases:

• Private Wealth Management: Individuals seeking financial privacy while maintaining control over assets.

• Crypto Custody Solutions: Storing and distributing cryptocurrency without exposing wallet addresses.

• Decentralized Philanthropy: Donors can distribute funds without recipients knowing their identity.

• Corporate or Political Funding: Organizations can fund initiatives while keeping contributors anonymous.
