How authentication NFT works on Blockchain

Key components of authentication NFT on the blockchain

1.Smart Contract

A smart contract is a code that defines the logic and operation of an authenticated NFT. Smart contracts are deployed and executed on the blockchain, and manage the creation, transfer of ownership, and transaction records of NFTs.

2.NFT Data

NFT data includes information about each certified NFT. This information records the NFT's unique identifier, owner address, authentication information, transaction, etc. NFT Data is data stored in the blockchain, and anyone can search the information of the NFT.

3.Blockchain Network

As seen in the diagram, the creation and control of authentication NFTs are managed by smart contracts. Additionally, there is a separate smart contract responsible for ownership transfer and another one for recording transactions. These smart contracts operate within a distributed blockchain network composed of multiple nodes, securely recording and maintaining information related to authentication NFTs, including their ownership and transaction records.

NFT Creation and Control: Refers to the smart contract responsible for creating and managing NFTs. This smart contract creates new NFTs and stores necessary information along with them.

Ownership Transfer: Refers to the smart contract responsible for facilitating the transfer of ownership of NFTs. This smart contract processes transactions that change the ownership of NFTs and ensures proper ownership transfers.

Transaction Recording: Refers to the smart contract responsible for recording transaction history. This smart contract records the transactions related to NFTs and securely maintains this information.

Blockchain Network: Refers to the distributed blockchain network where these smart contracts operate. This network consists of multiple nodes and is responsible for storing and maintaining information related to NFT creation, ownership transfer, and transaction records in a decentralized manner.

This structure highlights the vital role of the blockchain network in enhancing the reliability and security of authentication NFTs. By leveraging the distributed nature of blockchain, the system ensures a safe and trustworthy environment for authentication NFTs. Anyone can access the blockchain network to verify information about NFTs and transparently trace ownership and transaction records of authentication NFTs.

Smart contracts are programs executed on a blockchain network and each has a unique address. Through these addresses, the three smart contracts can operate independently, controlling necessary functionalities and storing data.

The blockchain network is composed of multiple nodes, which collectively share a distributed ledger of the entire network. In this decentralized structure, multiple smart contracts perform their respective roles, while the blockchain network handles the recording of transactions and state changes.

The operational structure of authentication NFTs on the blockchain

1.NFT Metadata: The metadata of an authentication NFT comprises essential information related to the NFT. It encompasses supplementary data like the title, description, image URL, artist details, and other pertinent information associated with the NFT.

2.Token ID: The unique identifier of an NFT. It is a value that uniquely identifies the specific NFT and distinguishes it from other NFTs.

3.Ownership Information: Ownership Information of an NFT: It includes details about the ownership of an NFT, such as the current owner's address and the previous owner's address. The owner's address represents the address that currently holds the NFT.

4.Certification Data: The certification data of an authentication NFT includes authentication-related information. It comprises additional details such as the original file hash of the artwork, artist information, artwork description, and other supplementary authentication information associated with the NFT.

5.Transaction History: The transaction history of an NFT captures the records of all past transactions related to the NFT. It contains data about the previous owner's address and provides detailed information about each specific transaction, allowing for comprehensive tracking of the NFT's transactional lineage.
