Abstract: In interpreting a data record in a blockchain of a certain cryptographic asset, it is usually necessary to use the API of the node software provided by the developer of the software that devises the implementation method. However, since an input/output method of the API also differs depending on the implementation method, it is difficult to collect and analyze blockchain data of cryptographic assets according to a plurality of different implementation methods. The present invention provides a cryptographic asset blockchain processing apparatus or the like that collects blockchain data generated by a plurality of different implementation methods, converts the data into data that can be analyzed, and processes a transaction content such as a quantity, a unit price, and a partner of a transaction cryptographic asset into a standardized format, thereby improving convenience of analysis of a large amount of data for an accounting audit or the like.
