System and method for publication of private data using a blockchain network

A system for encrypting and publishing data, comprising:

• a distributed network of nodes configured to collectively maintain a distributed ledger, wherein each node comprises a hardware processor configured to:
• receive a message requesting publication of private information within the distributed ledger subsequent to a specified time interval;
• record a sequence of transactions in the distributed ledger based on the time interval, wherein each transaction in the sequence of transactions includes a payload calculated using a first homomorphic operation, wherein the hardware processor is configured to record by:
• determining an initial payload based on an inverse mapping function applied to a first value of a sequence of private data values, wherein the sequence of private data values are selected such that a second homomorphic operation applied to the sequence of private data values yields the private information;
• and
• recording a first transaction of the sequence of transactions in the distributed ledger, wherein the first transaction includes the initial payload and a first transaction identifier associated with the first value in the sequence of private data values;
• extract the private information from a final payload of a final transaction in the sequence of transactions from the distributed ledger;
• and
• provide the extracted private information to a client node in response to determining that the specified time interval has expired.

A non-transitory computer readable medium comprising computer executable instructions for encrypting and publishing data, including instructions for:

• receiving, by one or more nodes of a distributed network that maintains a blockchain, a message requesting publication of private information within the blockchain subsequent to a specified time interval;
• recording a sequence of transactions in the blockchain based on the time interval, wherein each transaction in the sequence of transactions includes a payload calculated using a first homomorphic operation, wherein instructions for recording further comprises instructions for:
• determining an initial payload based on an inverse mapping function applied to a first value of a sequence of private data values, wherein the sequence of private data values are selected such that a second homomorphic operation applied to the sequence of private data values yields the private information;
• and
• recording a first transaction of the sequence of transactions in the blockchain, wherein the first transaction includes the initial payload and a first transaction identifier associated with the first value in the sequence of private data values;
• extracting the private information from a final payload of a final transaction in the sequence of transactions from the blockchain;
• and
• providing the extracted private information to a client node in response to determining that the specified time interval has expired.
