Abstract

Provided are a method of creating an index for blockchain data and a device and method for searching for blockchain data. The method of creating an index for blockchain data includes receiving, by a blockchain data search device, data to be stored in a blockchain network from a user application, requesting, by the blockchain data search device, the blockchain network to store the data and receiving a block number of a block in which the data is stored and a transaction identifier (ID) from the blockchain network when storage of the data is completed, and encrypting, by the blockchain data search device, the data and creating an index for the data on the basis of the encrypted data, the block number, and the transaction ID.

Dependencies are inferred from the claim text.
