Method and system for tuning blockchain scalability, decentralization, and security for fast and low-cost payment and transaction processing

A method of processing and validating transactions on a multi-chain network comprising:

• receiving a first plurality of transactions;
• recording the first plurality of transactions to a first block on a first blockchain in a multi-chain network;
• receiving a second plurality of transactions;
• recording the second plurality of transactions to a second block on the first blockchain in the multi-chain network;
• publishing the first and second plurality of transactions to a first managed topic associated with the multi-chain network on a first messaging server, defining a first published transactions;
• and
• transmitting the first published transactions to a first subscriber, defining a first transmitted transaction;
• wherein the first plurality of transactions comprises at least one of transferring value from one account to another, transferring value between smart contracts, sending a message to a topic or a smart contract, recording key-value pairs on the first blockchain, or storing data in a blockchain database;
• wherein receipt of the first transmitted transaction by the first subscriber initiates a generation of a first merged block comprising the first published transactions and recording of the first merged block to a second blockchain on the multi-chain network;
• wherein the first blockchain has a parameter difference from the second blockchain selected from the group consisting of block generation time, transaction throughput, transaction latency, stale block rate, block propagation delay and consensus algorithm used;
• and
• wherein the second blockchain is comparatively de-centralized when compared to the first blockchain.

A system for processing and validating transactions on a multi-chain network comprising:

• a processor;
• a data store operably coupled to the processor;
• and
• a network communication device positioned in communication with each of the processor, the data store, and a network;
• wherein the network communication device is operable to receive a first plurality of transactions;
• wherein the processor is operable to record the first plurality of transactions to a first block on a first blockchain in a multi-chain network;
• wherein the network communication device is operable receive a second plurality of transactions;
• wherein the processor is operable to record the second plurality of transactions to a second block on the first blockchain in the multi-chain network;
• wherein the network communication device is operable to transmit the first and second plurality of transactions to a first managed topic associated with the multi-chain network on a first messaging server, defining a first published transactions;
• and
• wherein the first messaging server is operable to transmit the first published transactions to a first subscriber, defining a first transmitted transaction;
• wherein receipt of the first transmitted transaction by the first subscriber initiates a generation of a first merged block comprising the first published transactions and recording of the first merged block to a second blockchain on the multi-chain network;
• and
• wherein the first blockchain has a parameter difference from the second blockchain selected from the group consisting of block generation time, transaction throughput, transaction latency, stale block rate, block propagation delay and consensus algorithm used.
