Storing time-sensitive secrets in a blockchain network

A system, comprising:

• a memory storing instructions;
• and
• one or more processors configured to execute the instructions to:
• receive, in a block producer and from a content provider, a first encryption key selected from among multiple encryption keys, the multiple encryption keys being associated with a first time window;
• access, from a blockchain application in a server, a data packet encoded according to the encryption keys, the data packet provided to the server by the content provider;
• write a decrypted data packet to a block in a blockchain when the first encryption key matches a first time-sensitive value;
• write the decrypted data packet to the block in the blockchain when a second encryption key, received from the content provider, matches a second time-sensitive value after the first time-sensitive value has lapsed, wherein the first time-sensitive value and the second time-sensitive value are a non-overlapping time sequence in the first time window;
• and
• form the first encryption key with a first component from the block producer and a second component from the blockchain application.

A non-transitory, computer-readable medium storing instructions which, when executed by a processor, cause a computer to perform a method, the method comprising:

• receiving, in a block producer and from a content provider, a first encryption key selected from among multiple encryption keys, the multiple encryption keys associated with a first time window;
• accessing, from a blockchain application in a server, a data packet encoded according to the encryption keys, the data packet provided to the server by the content provider;
• writing a decrypted data packet to a block in a blockchain when the first encryption key matches a first time-sensitive value;
• writing the decrypted data packet to the block in the blockchain when a second encryption key, received from the content provider, matches a second time-sensitive value after the first time-sensitive value has lapsed, wherein the first time-sensitive value and the second time-sensitive value are a non-overlapping time sequence in the first time window;
• forming the first encryption key with a first component from the block producer and a second component from the blockchain application;
• and
• invalidating one of the first encryption key and the second encryption key, when it has been used.
