Embodiments of the disclosure provide methods and systems for evaluating and recording a property of a system of interest (SOI) such as, e.g., a property of artificial intelligence (AI), and recording a change to the property of the SOI, e.g., recording a morphism of AI. Recording an SOI property, and any property changes, may include recording a digital property of the SOI to a blockchain. An SOI morphism may be recorded to a blockchain as one or more hash values of an encoding of the SOI. An SOI morphism may be autonomously or exogenously generated and recorded to the blockchain. The records on the blockchain may indemnify one or more parties associated with the SOI. Indemnifying may include executing a smart contract on a blockchain to mitigate risk of loss. An SOI may be asked to complete one or more tests to distinguish between a human, AI, and non-AI programs.
