Classification: CPC G | IPC G

Claim 0:
1. A method of interacting with a consumer ledger, the method comprising:
maintaining, by a computing device, a portion of a blockchain (BC) using a Practical Byzantine Fault Tolerance (PBFT) cryptographic scheme with at least two-thirds of a plurality of miners being verified to mine the BC and current miners actively participating on the BC rotate turns to create BC blocks on the BC;
receiving, by a computing device, a copy of the consumer ledger from one of the plurality of miners, wherein receiving the copy of the consumer ledger includes the computing device issuing a pull command requesting the copy of the consumer ledger from the BC in order to add a transaction to the consumer ledger;
adding, by the computing device, the transaction to the consumer ledger on the BC by a verified miner that is one of the plurality of miners and a member of a consumer loyalty program, the verified miner being one of a plurality of verified miners operated by a plurality of retailers or service providers and given a greater weight in verifying the transaction;
creating, by the computing device, a block on the BC using the transaction added to the consumer ledger;
transmitting, by the computing device, the block to the plurality of miners for conformation;
signing, by a majority of the plurality of miners, the block on the BC; and
speeding up a time taken to process the transaction, reducing latency of the transaction, and increasing network throughput for the transaction as compared to processing a conventional BC transaction by processing the method for the transaction.
