US Patent 11017405 Blockchain compliance platform and system for regulated transactions

Regulated crypto-assets, or blockchain tokens, that are regulated as securities (security tokens) can be purchased using a compliance platform through a compliance wallet that allows token purchasers and token sellers to purchase and sell security tokens in a regulatory compliant manner. A rules engine of the compliance platform determines what compliance rules need to be satisfied for a given transaction and guides the token purchasers through a compliance process. Token sellers, upon being presented with a request to purchase tokens on the blockchain, can verify approved transactions on the compliance platform to ensure that the transaction can be compliantly processed.
