This is helping me understand Cashu and blind signatures better:

“The problem is if they see the token when they sign it, then they will know who they signed it for and can know who made a payment when someone else comes to them to redeem it. To address this, a second random value, a blinding factor, is generated by the user before having the mint notarize a token. The binding factor is essentially multiplying the token value by the blinding value.”
