A method for expedited inclusion of pre-authorized blockchain transactions in new blocks. A blockchain node will utilize a traditional pending transaction pool of unconfirmed transactions, but will also utilize a new transaction pool that is comprised of pending blockchain transactions that have been confirmed, but have not yet been added to the blockchain. When a new block is being generated by a node, they can select pending transactions from the confirmed transaction pool and include them in the new block without repeating the confirmation process, which can save time and computing resources, thereby enabling the new block to be generated faster and increasing the chance that the new block will be the one that is validated and added to the chain. Additional rules and criteria can be applied to ensure that transactions that are in the confirmed transaction pool are added to a new block in a timely fashion.

Method and system for authorization and settlement in blockchain transactions

A method for processing cryptographic currency transactions through user-based blockchain ledgers includes: receiving, by blockchain node in a blockchain network, a new cryptographic currency transaction from a first computing device including unspent transaction outputs, a sender public key, receiver public key, destination address, and cryptographic currency amount; identifying, by the blockchain node, a sending blockchain associated with the sender public key including the unspent transaction outputs; validating, by the blockchain node, the sending blockchain by generating a hash value using the sending blockchain and comparing the generated hash value to a historic sender hash value associated with the sender public key; generating, by the blockchain node, a new sender hash value by hashing a combination of the sending blockchain and the new cryptographic currency transaction; and transmitting, by the blockchain node, the generated new sender hash value to a plurality of additional nodes in the blockchain network.
