Intelligent health-based blockchain

A computer-implemented method comprising:

• receiving, by at least one node of a blockchain from a first electronic sensor, health data associated with a user, the first electronic sensor configured to monitor and capture the health data associated with the user;
• periodically updating, by the at least one node of the blockchain, the blockchain using the health data associated with the user, where the updating comprises:
• storing, by the at least one node of the blockchain, first health data associated with the user and received from the first electronic sensor and second health data associated with the user and received from a second electronic sensor in volatile memory storage over the course of a first pre-determined time period;
• responsive to detecting an end to the first pre-determined time period, retrieving, by the at least one node of the blockchain, a latest valid block instance of the blockchain from a plurality of nodes of the blockchain, wherein block instances of the blockchain comprise encrypted health data associated with the user received from the first electronic sensor over different pre-determined time periods and corresponding hash values, wherein the latest valid block instance is stored in a database associated with at least one of the plurality of nodes;
• generating, by the at least one node of the blockchain, a file with the first health data and the second health data of the first pre-determined time period from the volatile memory storage;
• comparing, by the at least one node of the blockchain, a hash value associated with at least a portion of the latest valid block instance with a hash value of a corresponding latest valid block instance retrieved from at least one other node within the blockchain;
• and
• upon a number of matching hash values satisfying a pre-determined threshold, appending, by the at least one node of the blockchain, a new block instance comprising the generated file with the first health data and the second health data of the first pre-determined time period and a new hash value generated according to a hashing algorithm to the latest valid block instance.
