Systems and methods for re-organizing blockchains for efficient operations

A method for recording a transaction between first and second transacting network nodes associated with a global blockchain, comprising:

• associating first and second transacting network nodes with a selected sub-chain of the global blockchain, the selected sub-chain being selected from among a plurality of sub-chains of the global sub-chain;
• in response to the first transacting network node causing cryptocurrency to be sent to a first public address associated with the second transacting network node as part of a given transaction between the first and second transacting network nodes, causing the given transaction to be recorded in the selected sub-chain;
• and
• subsequent to recording the given transaction on the selected sub-chain, causing the transaction to be recorded on the global blockchain using a second public address of the second transacting network node, wherein the recording is performed using an atomic commit process that prevents the first and second transacting network nodes from conducting any other transactions while the given transaction is being recorded on the global blockchain.
