A blockchain is a distributed database that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. The innovation with a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party. [1]

Polygon is a secondary scaling solution for the Ethereum blockchain. These types of solutions work on top of an existing blockchain network rather than using their own blockchain. In this instance, Polygon works on top of Ethereum which has become slow and expensive to use as it becomes ever more popular. [2]

NFT stands for non-fungible token. Non-fungible is an economic term that you could use to describe things like your furniture, a song file, or your computer. These things are not interchangeable for other items because they have unique properties. Every NFT must have an owner and this is of public record and easy for anyone to verify. Creators can retain ownership rights over their own work, and claim resale royalties directly. [3]

The metaverse is a future evolution of the Internet based on persistent, shared virtual worlds in which people interact as 3D avatars. Blockchain technology may provide the backbone of the metaverse, with interoperable NFT assets that can be used across different metaverse spaces. [4]
