Description

This disclosure relates to a data management system, a data management method, and a server. Japanese Patent Publication No. 2022-13271 (Patent Document 1) discloses a distribution platform for non-fungible tokens that eliminates the need for wallet preparation, private key management, and payment of network fees (such as gas). Japanese Patent Publication No. 2022-13271 This figure shows an example of the overall configuration of the blockchain ecosystem according to the embodiment of this disclosure.This figure shows another example of the overall configuration of the blockchain ecosystem according to the embodiment of this disclosure.A typical example of a marketplace configuration is shown in the block diagram.This is a conceptual diagram of the NFT badge in this embodiment.This diagram illustrates the target conditions for earning an NFT badge.This diagram illustrates the overview of the processing related to NFT badges in this embodiment.This is a sequence diagram showing the series of processing steps involved in registering an NFT badge.This flowchart shows an example of the processing procedure for determining target conditions.This is a sequence diagram showing the series of processing steps involved in granting NFT badges.This is a sequence diagram illustrating the series of processing steps involved in trading NFT badges. The embodiments of this disclosure will be described in detail below with reference to the drawings. Parts identical or corresponding to those shown in the drawings are denoted by the same reference numerals, and their descriptions will not be repeated. [Embodiment] <System Configuration> Figure 1 shows an example of the overall configuration of a blockchain ecosystem according to an embodiment of this disclosure. The blockchain ecosystem 10 manages data using blockchain technology. In this embodiment, the data managed by the blockchain ecosystem 10 is nonfungible tokens (NFTs) that are assigned to the way a vehicle is driven. More specifically, when pre-registered "target conditions" (details described later) regarding environmentally and/or safe driving are achieved, an NFT-enabled certificate is assigned to the driver. Since this certificate has a badge-type design, the NFT-enabled certificate will be referred to as an "NFT badge" below. The NFT badge will be described in detail from Figure 4 onwards. The blockchain ecosystem 10 comprises multiple nodes 9 and a data management system 20. Each of the multiple nodes 9 is a computer device such as a server. Blockchain-based software is installed on each node 9. Multiple nodes 9, each possessing blockchain node functionality, communicate with each other via a network (NW), forming a distributed ledger network (blockchain network). The distributed ledger network may be public, a consortium, or private. The data management system 20 includes, for example, a marketplace 1, multiple designer terminals 2, multiple registrant terminals 3, multiple vehicles 4, multiple driver terminals 5, and multiple trader terminals 6. The number of each component in the data management system 20 is not particularly limited. To avoid complexity, the following description assumes that the data management system 20 includes one of each component. Marketplace 1 is operated by an organization (such as a company, association, or joint venture) that manages NFT badges. Marketplace 1 typically includes a server (see Figure 3). Marketplace 1 is connected to the designer terminal 2, registrant terminal 3, vehicle 4, driver terminal 5, and trader terminal 6 via wired or wireless communication. Marketplace 1 manages (distributes) the costs and rewards incurred in connection with various processes related to NFT badges (registration, issuance, exchange, etc.). Marketplace 1, for example, obtains driving information for vehicle 4 from the driver terminal 5. The method of obtaining the driving information for vehicle 4 is not limited. Marketplace 1 may obtain the driving information for vehicle 4 directly from vehicle 4, or it may obtain the driving information for vehicle 4 from a data center that collects driving information for various vehicles (typically a server operated by the vehicle manufacturer). Marketplace 1 is communicatively connected to at least one of the multiple nodes 9. Nodes 9 connected to Marketplace 1 are referred to as node 91, and those not directly connected to Marketplace 1 are referred to as node 92. Marketplace 1 requests node 91 to issue NFT badges and requests node 91 to change the ownership of NFT badges (e.g., exchange NFT badges). The designer terminal 2, registrant terminal 3, driver terminal 5, and trader terminal 6 are typically smartphones, tablets, personal computers, workstations, etc. However, a server may be used instead of such client terminals. The designer terminal 2 registers the NFT badge design (a digital image for visually confirming the NFT) created by the designer. The registrant terminal 3 registers the target condi
