Learning about the Web3 space is one of the most important things for any person looking to understand the future of technology. This Web3 glossary of terms will help you get more familiar with the usual jargon used in this space.

Web3 consists of a number of technologies, including blockchain, decentralized applications (dApps), non-fungible tokens (NFTs), and cryptocurrencies, that are all connected and used to create a new, more secure and trustless way of exchanging value and data.

The list of commonly used terminology in Web3 is an essential part of understanding how these technologies work and interact, and can be a great starting point for anyone looking to get involved in the space. Lets get into it!

Consensus Mechanism (noun)
