NFT development technology and NFT application scenario analysis

NFT is a popular "outsider". Many customers and friends are curious about how NFT is operated and realized. Today, scallop technology, a stack service provider specializing in the development and incubation of blockchain technology, will reveal the underlying technology, deployment public chain and application scenarios of NFT.

The essence of NFT

NFT is the abbreviation of non-exchangeable token, which means non-exchangeable token. Like a work of art, everything is unique. The essence of NFT is a heterogeneous token generated on the blockchain network.

Basic agreement

Based on the technical advantages of blockchain technology, such as decentralization, tamper resistance, timestamp, etc. By determining the value of offline items to NFT, the ownership of works of art can be realized and transactions can be inquired. At present, NFT has three basic protocol standards, namely ERC72 1, ERC 1 155 and ERC998.

You can adopt different protocol standards according to different NFT application scenarios.

Generally speaking, ERC72 1 is the first and most commonly used underlying protocol standard. From ERC72 1 to ERC998, it is a process of gradual upgrading of functions:

From ERC72 1 to ERC 1 155, token transfer transaction can be a more convenient and lower-cost transaction;

From ERC 1 155 to ERC998, token package transaction and multi-scenario application can be realized.

Deploy a common chain.

Then, you can choose to deploy and develop on the chain such as Ethereum or traffic. Compared with the earliest NFT underlying main chain-Ethereum, Flow solves the network congestion problem, realizes the large-scale expansion of fragmentation-free technology, and provides high-speed and low-cost transactions.

Of course, ethereum layer2 aggregator polygon is also a good choice. NFT projects deployed on Polygon include Aavegotchi, Neon District, distributed games, battle racing, Doki Doki and so on.

Application scenario

One of the main application scenarios of 1 NFT is a game. NFT based on blockchain technology can record the status and achievements of players in the game, as well as the list of items obtained in the survival game, such as weapons, power supplies, vehicles, people and so on.

2.2 is another main use. NFT is art, music, tickets, fun, cards, paintings, photos, GIF animations, emoticons and so on. Except for the file format, audio NFT is no different from other NFTs in technology, but they mainly realize multi-dimensional presentation by fusing audio clips with underlying images or videos.

3. In addition, there are other physical assets in the field of physical assets, such as houses and other real estate, which can be expressed by NFT tokens and can be used as circulating assets in the financial market. For example, if you have a house and want to lock it up, you will definitely use NFT to make sure that you are the owner of the house. The registration and sale of the house are initially sent out through the NFT chain, and then through the STO gateway, your NFT token is expected to be converted and confirmed. Moreover, compared with traditional assets, NFT assets have higher liquidity. In reality, it usually takes dozens of days to complete the change of property rights. If the property ownership is determined by NFT assets, the transfer of assets can be realized in a few seconds.

4. Thanks to the vigorous development of DeFi, financial products can also be tokenized in the form of NFT. As a unique NFT, the token policy can be transferred, traded and earned in some cases. Compared with the red tape of traditional insurance, now users only need to fill in the items and amount of encrypted assets to be protected, and they can get the insurance policy, which greatly improves the efficiency. For example, bancassurance, learning finance and so on.

A right-hand man for NFT application virtual requirements development

In addition to the above scenarios, NFT can also be used to record and identify, verify identity and birth certificate, driver's license, academic certificate and so on. These can be stored securely in digital form to prevent abuse or tampering. It can also be applied to invoices, orders, insurance, bills, etc. And turn these financial vouchers into NFT for trading.
