A system and method is provided for a unique logger associated with a unique cryptographic private and public key pair and certificate to record a log which can be uploaded and verified on an immutable blockchain by an agent holding the other cryptographic private key and the public key recorded on the blockchain. Preferably, the logger is configured to automatically record and encrypt a log with its unique public cryptographic key in response to detection of certain pre-determined conditions configured by an agent, and store such log in non-volatile memory together with time stamps. The logger is also configured by an agent to upload the encrypted log to an immutable blockchain after a certain time period or in response to detection of certain pre-determined conditions. The agent holding the private cryptographic key can decrypt the immutable log on the blockchain to cryptographically verify the authenticity of the log.
