System for processing data based on blockchain and operating method thereof

A system for processing data comprising:

• a first blockchain network including a first plurality of blockchain nodes, wherein a first blockchain is associated with the first blockchain network;
• and
• a second blockchain network including a second plurality of blockchain nodes, wherein
• a second blockchain is associated with the second blockchain network, and
• the first blockchain network is configured to process a first transaction for a first electronic wallet of a user, and
• the second blockchain network is configured to process a second transaction for a second electronic wallet of the user, and
• a total balance of electronic currency associated with the user is a sum of a first balance of the first electronic wallet and a second balance of the second electronic wallet.

A method comprising:

• receiving, by a first blockchain node among a plurality of blockchain nodes, a transaction request, wherein the transaction request is associated with a target transaction, a first user as a sender and a second user as a receiver;
• verifying, by the first blockchain node, a validity of the target transaction;
• providing a notice, by the first blockchain node to a terminal of the second user, of a completion of the verifying of the target transaction;
• and
• transferring, by the first blockchain node, transaction data associated with the transaction request to a block generation node;
• wherein the transaction data is recorded, by the block generation node, in a new block, and
• the transaction request is processed in response to the completion of the verifying before being recorded in the new block.
