Abstract: A ledger information access system having a plurality of storage spaces, according to the present invention, comprises: a transaction packer for adding, to generated transaction proposals, key information corresponding to a transaction request; a transaction aggregator, which separates common keyset information from common transaction batch information according to the common transaction batch information, so as to transmit each to a predefined execution node group; at least one transaction executor, which belongs to the execution node group, executes a simulation for transaction proposals included in the common transaction batch information transmitted from the transaction aggregator, and transmits the common keyset information; and a ledger manager which includes a plurality of storage spaces for storing each of a plurality of part blocks in which pieces of transaction information constituting one block connected to a blockchain are distributed, and which reads, from the plurality of storage spaces, pieces

Abstract: A system for accessing ledger information by using common keyset information according to the present invention comprises: a transaction packer for adding key information corresponding to a transaction request to a generated transaction proposal; a transaction aggregator for generating 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 transmitting 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 for executing 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 transferring the common keyset information; and a ledger manager for
