Abstract
A system and methods include a negative certificate authority for distributed management of negative certificates. An authorization restriction is associated with an untrusted user. A negative certificate generated for the untrusted user includes a public key associated with the untrusted user and an authorization restriction. The authorization restriction includes at least one global restriction, which is applicable to each consortium member that subscribes to the negative certificate. The authorization restriction includes at least one local restriction, which allows individual consortium members to further define their own locally applicable restrictions using the negative certificate authority. The negative certificate is accessible to each member of the consortium to enforce the authorization restriction against a transaction request. A secure contributor record including a unique cryptographically generated address is generated for each contributor. In some embodiments, the transaction request is a blockchain-based value exchange transaction, such as a payment transaction using fiat or math-based currency.
