Abstract: A method for aggregated storage of observational data on a blockchain includes: receiving, by a receiver of a processing server, a plurality of data entries, wherein the plurality of data entries includes (i) one or more data entries received from each of a plurality of different external devices, or (ii) multiple data entries received from one external device; canonicalize, by a processor of the processing server, the received plurality of data entries into a single data value; hashing, by the processor of the processing server, the single data value to generate a hashed data value; transmitting, by a transmitter of the processing server, the hashed data value to a blockchain node in a blockchain network; receiving, by the receiver of the processing server, a reference value from the blockchain node; and storing, in a memory of the processing server, the received reference value with the plurality of data entries.

Abstract: A method for triggering payment transactions through predetermined events identified using a blockchain includes: receiving, at a first system, trigger data including a first account identifier, second account identifier, and trigger event values; receiving, at the first system, blockchain data values, each including a hash value; identifying, by the first system, a match between a specific blockchain data value and a specific trigger event value based on the hash value; transmitting, by the first system, a notification message to a second system including the first account identifier and second account identifier; identifying, by the second system, a first payment identifier using the first account identifier and a second payment identifier using the second account identifier; and initiating, by the second system, a payment transaction for payment from a transaction account associated with the first payment identifier to a transaction account associated with the second payment identifier.
