Claim 8:
9. A processor-implemented method for information storage and retrieval using a distributed ledger, comprising:
generating, via the processor and for a first tangible asset represented by a first hierarchical hash-linked tree data structure stored in an off-chain database, a first root node associated with the first tangible asset, the first root node having (1) a first hash value, stored in a distributed ledger, that represents an off-chain storage location of the first root node, (2) data associated with the first tangible asset, and (3) a second hash value of the first root node of the first hierarchical hash-linked tree data structure that represents a storage location of a subsidiary node of the first root node, wherein the first hash value being associated with a state of a smart contract that includes the second hash value, the state of the smart contract representing a snapshot of data stored in the smart contract; and
generating, via the processor and in response to combining the first tangible asset and a second tangible asset, a second root node of a second hierarchical hash-linked tree data structure associated with a third tangible asset including the first tangible asset and the second tangible asset, the second root node having (1) a third hash value that represents an off-chain storage location of the second root node, (2) data associated with the third tangible asset, and (3) a fourth hash value that represents a storage location of a subsidiary node of the second root node of the second hierarchical hash-linked tree data structure.
