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.

Abstract: A method for moderation in a permissioned blockchain using a hash-oriented scheme includes: storing a blockchain including a most recent block; receiving transaction data values; receiving a first reference value and a second reference value; generating a first hash value by hashing the first reference value; generating a block proof including the first hash value, a second hash value, a third reference value, and a block value; verifying a block header of the most recent block using the block proof; receiving a new block value; generating a new block header including the first reference value, the second reference value, a fourth reference value, and the new block value; generating a new block for the blockchain including the new block header and the transaction data values; and transmitting the new block to one or more additional nodes associated with the blockchain.
