Decentralized data storage and processing for IoT devices

An apparatus comprising:

• memory;
• instructions;
• and
• processor circuitry to execute the instructions to:
• cause storage of a file in storage;
• generate a hash value corresponding to the file;
• cause storage of the hash value on a blockchain to be accessible to multiple nodes in a distributed network;
• and
• verify contents of the file have not changed based on the hash value on the blockchain.

A system comprising:

• storage to store a file;
• and
• a device to:
• generate a hash value corresponding to the file;
• cause storage of the hash value on a blockchain to be accessible to multiple nodes;
• and
• verify contents of the file have not changed based on the hash value on the blockchain.

A method comprising:

• causing storage of a file in an off-chain storage;
• generating, by executing an instruction with at least one processor, a hash value corresponding to the file;
• causing storage of the hash value on a blockchain to be accessible to multiple nodes;
• and
• verifying, by executing an instruction with the at least one processor, contents of the file have not changed based on the hash value on the blockchain.
