Claim 8:
9. A system for generating digital certificates for anonymous users in blockchain transactions, comprising:
a memory of a processing server configured to store a blockchain, wherein the blockchain is comprised of a plurality of blocks, each block including a block header and one or more transaction values, where each transaction value includes data related to a blockchain transaction including at least a sending address, a recipient address, and a transaction amount;
a receiving device of the processing server configured to receive a certificate request from a computing device, wherein the certificate request includes at least a user public key of a cryptographic key pair;
a determination module of the processing server configured to determine a confidence level associated with the computing device based on at least the data included in each transaction value included in a subset of transaction values included in the blockchain where the included sending address or recipient address was generated using the user public key;
a generation module of the processing server configured to generate a digital certificate based on the determined confidence level associated with the computing device; and
a transmitting device of the processing server configured to electronically transmit the generated digital certificate to the computing device,
wherein responsive to the computing device engaging in a blockchain transaction with a secondary computing device, the computing device having sent the generated digital certificate to the secondary computing device, the generated digital certificate is configured to cause the secondary computing device to transmit the blockchain transaction to a node associated with the blockchain responsive to the determined confidence level associated with the computing device being equal to or above a confidence level associated with the secondary computing device.
