A method for interconnecting data between a plurality of blockchain networks according to an embodiment of the present invention includes receiving a request of an interconnecting transaction for interconnecting data between a plurality of blockchain networks, querying information of an ongoing or scheduled transaction through the plurality of blockchain networks in response to the request, and selectively determining any one of a plurality of interconnecting schemes as an interconnecting scheme of the interconnecting transaction with reference to the queried information, and performing the interconnecting transaction according to the determined interconnecting scheme.

Method for associating data between a plurality of blockchain networks and apparatus thereof

A method for managing transaction is performed in a blockchain-based computing system and includes receiving a request for processing a first individual transaction from a client terminal, generating a batch transaction by aggregating a plurality of individual transactions including the first individual transaction, processing the generated batch transaction via a blockchain network, such that a status record associated with the batch transaction is recorded in the blockchain, and providing the client terminal with an identifier of the batch transaction and index information on the first individual transaction, wherein the status record associated with the batch transaction includes a first status record associated with the first individual transaction, and wherein the index information on the first individual transaction is determined based on a location of the first status record in the status record.

Blockchain-based computing system and method for managing transaction thereof

An apparatus for guaranteeing the integrity of a state database includes a memory for storing one or more instructions, a communication interface for communicating with one or more blockchain nodes and a processor. The processor is configured, by executing the stored one or more instructions, to receive a request to query for a state value, obtain a first state value by querying a state database in response to the request, forward the request to the one or more blockchain nodes to receive a second state value from the one or more blockchain nodes and compare the first state value with the second state value to determine integrity of a state value.

Apparatus for guaranteeing integrity of state database in blockchain-based environment and method thereof

A decentralized key management system according to an embodiment of the present disclosure includes a bootstrap for generating a key and obtaining a certificate corresponding to the generated key, a memory for receiving the key and the certificate from the bootstrap and storing the key and the certificate, a container, in response to a mount command of the bootstrap, for reading the key and the certificate from the memory and being mounted with the key and the certificate, and a controller for generating the bootstrap, and deleting the bootstrap after the container mounts the key and the certificate.
