Abstract

Systems and methods may include contributing to a quantum-resistant blockchain that stores a quantum-resistant audit trail of changes to a dataset. A non-transitory computer readable medium may store instructions that are run on a computer processor to populate a block with a log of a dataset, run a quantum-resistant cryptographic algorithm to encrypt the block, distribute the block to and receive approval from blockchain nodes to add the block to the blockchain, and run the algorithm to encrypt the block onto the blockchain. The method may include repeating the steps of running the non-transitory medium on the computer processor to populate a second block with a second log of the dataset, run the algorithm to encrypt the second block, distribute the second block to and receive approval from the blockchain nodes to add the block to the blockchain, and run the algorithm to encrypt the second block onto the blockchain.

A computing system for contributing to a quantum-resistant blockchain that stores a quantum-resistant audit trail of changes to a dataset, comprising:

a computer processor;
and
a computer-readable medium, coupled with the computer processor, having instructions stored thereon, that, when executed by the computer processor, cause the computing system to perform a method, the method comprising:
populating a first block with a first log of a first version of the dataset;
encrypting, using the computer processor to run a quantum-resistant cryptographic algorithm, the first block with a hash;
distributing, using the computer processor, the first block to one or more blockchain nodes;
receiving, at the computer processor, from the one or more blockchain nodes, approval to add the first block to the quantum-resistant blockchain;
encrypting, using the computer processor to run a quantum-resistant cryptographic algorithm, the first block onto the quantum-resistant blockchain with a hash;
populating, using the computer processor, a second block with a second log of a second version of the dataset;
encrypting, using the computer processor to run a quantum-resistant cryptographic algorithm, the second block with a hash;
distributing, using the computer processor, the second block to the one or more blockchain nodes;
receiving, at the computer processor, from the one or more blockchain nodes, approval to add the second block to the quantum-resistant blockchain;
encrypting, using the computer processor to run a quantum-resistant cryptographic algorithm, the second block onto the quantum-resistant blockchain with a hash;
populating, using the computer processor, a third block with a third log of a third version of the dataset;
encrypting, using the computer processor to run a quantum-resistant cryptographic algorithm, the third block with a hash;
distributing, using the computer processor, the third block to the one or more blockchain nodes;
receiving, at the computer processor, from the one or more blockchain nodes, approval to add the third block to the quantum-resistant blockchain;
and
encrypting, using the computer processor to run a quantum-resistant cryptographic algorithm, the third block onto the quantum-resistant blockchain with a hash;
wherein:
the first log of the first version of the dataset comprises an initial version of the dataset and the first block comprises an initial block in the quantum-resistant blockchain;
or the first log of the first version of the dataset comprises one or more changes between the first version of the dataset and a version of the dataset before the first version of the dataset and the first block comprises a block in the quantum-resistant blockchain that, in addition to the first block, second block, and third block, comprises one or more blocks before the first block;
the first dataset, the second dataset, and the third dataset each comprise data at rest;
differences between the contents of the first dataset and the contents of the second dataset are recorded in the second log;
differences between the contents of the second dataset and the contents of the third dataset are recorded in the third log;
and
the quantum-resistant audit trail comprises the first log, the second log, and the third log.
