- 1. A blockchain record storage system comprising:
a processor; and a non-transitory computer readable medium storing machine-readable instructions that when executed by the processor cause the processor to:
receive a record including:
a file; and
metadata associated with the file;
generate a hash of the record;
store the record on an off-chain storage; and
deploy the hash to a blockchain.
- 13. An immutable record storage system comprising:
a processor; and a computer readable medium storing machine-readable instructions that when executed by the processor cause the processor to:
authenticate a participant based on credentials and a configuration file;
receive a record from the participant;
generate a hash of the record;
deploy the hash on a the blockchain; and
store the record in an off-chain storage.
- 18. A computer-implemented method for storing an immutable record on a blockchain, the method comprising:
receiving a context schema for a record, wherein the context schema comprises:
a state map describing states of the record;
and
a persona list of acceptable personas to interact with the record in different states;
receiving the record; receiving an initial parameter for the record based on the context schema; updating the record with the initial parameter; generating a hash of the record; and deploying the hash as a blockchain object to the blockchain.
