Delegating credentials with a blockchain member service

A system, comprising:

• a blockchain member device;
• a computing device configured to
• receive a signed transaction from the blockchain member device;
• responsive to the signed transaction received, identify a credential assigned to the blockchain member device, wherein the credential certifies a public key is assigned to the blockchain member device and was used to sign the signed transaction;
• determine whether to commit the signed transaction to a blockchain based on the credential;
• and
• responsive to a determination to commit the signed transaction based on the credential, store the signed transaction anonymously in the blockchain.

A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:

• receiving a signed transaction from a blockchain member device;
• responsive to receiving the signed transaction, identifying a credential assigned to the blockchain member device, wherein the credential certifies a public key is assigned to the blockchain member device and was used to sign the signed transaction;
• determining whether to commit the signed transaction to a blockchain based on the credential;
• and
• responsive to determining to commit the signed transaction based on the credential, storing the signed transaction anonymously in the blockchain.
