System and method for accessing ledger information by using common keyset information

A system for accessing ledger information by using common keyset information, comprising:

• a transaction packer configured to generate a transaction (Tx) proposal indicating transaction information according to a user's transaction request and add key information corresponding to the transaction request to the generated transaction proposal;
• a transaction aggregator configured to generate common transaction batch information and common keyset information corresponding to the transaction proposal according to the key information included in the transaction proposal received from the transaction packer, and transmit the common transaction batch information and the common keyset information to each execution node group distinguished and predesignated with regard to the common transaction batch information;
• at least one transaction executor configured to execute a simulation regarding the transaction proposals included in the common transaction batch information transmitted from the transaction aggregator, which belongs to the execution node group, and transfer the common keyset information;
• and
• a ledger manager configured to receive the common keyset information from the transaction executor, retrieve key value information corresponding to the common keyset information from blockchain ledger information and transfer same to the transaction executor.
