System and method using zero knowledge proofs for alert sharing

A method of proving knowledge of an entity, the method comprising:

• downloading to a local computer from a blockchain published code corresponding to details for an entity;
• executing on the local computer the published code using the details;
• and
• if the published code indicates a match of the details for the entity, determining that the entity is the same as the entity for which the code was published, generating a proof, and publishing the proof to the blockchain.

A system for securely sharing proof of knowledge of information without revealing the information, the system comprising:

• a memory;
• and
• a processor configured to:
• generate code which takes as input one or more details regarding an entity and returns a value based on a match to one or more actual details regarding the entity;
• generate a name for the code based at least in part on information describing the entity;
• publish the code to a blockchain;
• and
• publish at least one key corresponding to the code to a blockchain.
