Claim 0:
1. A data communication system for transferring data from a hardware unit to a blockchain or other distributed ledger, comprising:
a hardware interface to connect to the hardware unit;
a device in turn comprising:
a microcontroller,
a secure element connected to the microcontroller,
first communication module,
a communication protocol for enabling the microcontroller to communicate with the hardware interface through the first communication module, and

wherein the microcontroller is operable to: read data from the hardware unit through the hardware interface; generate a transaction corresponding to the data; securely generate a blockchain private key dB; digitally sign the transaction by means of using the blockchain private key dB; deliver the digitally signed transaction, and then delete the blockchain private key dB from volatile memory of the hardware unit, wherein the microcontroller is adapted to generate the blockchain private key dB from parameters contained in part from the device itself and in part from the hardware interface.
