Create Dynamic Non-Fungible Tokens (NFT) Using Chainlink Oracles

A Non-Fungible Token (NFT) is a cryptographically secured token existing on the blockchain that represents ownership of something unique. NFTs can represent tokenized ownership claims to real-world assets like a specific piece of land, or actual ownership of digital assets as in a rare digital trading card. Unlike fungible tokens such as Bitcoin where one BTC can be exchanged for any other BTC, each NFT is completely unique and represents verifiable digital scarcity.

Most of the NFT community is familiar with the idea of storing unique items as pieces of data on the blockchain. The blockchain acts as a standardized medium for listing and trading non-fungible assets that are transparent, globally accessible, and more liquid. It also provides a protected environment to store a trusted set of historical records about an asset dating back to its provenance.

Registering unique assets and freely trading them on a common decentralized platform (blockchain) has standalone value. The limitation is that the blockchain creates its value of decentralized security by disconnecting from all other systems, meaning NFT-based assets do not interface with data and systems outside the blockchain (static). Oracles have the ability to resolve this connectivity problem by allowing NFTs to interact with the outside world.

Dynamic NFTs that Respond to Data and Interface with Existing Infrastructure

The next evolution in NFTs is moving from static NFTs to dynamic NFTs— perpetual smart contracts that use oracles to communicate with and react to external data and systems. The oracle allows the NFT to use external data/systems as a mechanism for minting/burning NFTs, trading peer-to-peer, and checking state. For example, a smart contract that automates the minting of a limited edition digital soccer card if the oracle informs it that a player scored a hat-trick.
