The Web 3 world is filled with jargon. To help you to navigate this space, we’ve gathered some of the key terms and their high-level meaning.


The very first decentralised, peer-to-peer, digital currency, created by the pseudonymous Satoshi Nakamoto in 2009.


A blockchain is a distributed database that is shared among the nodes of a computer network. Blockchains store a continuously growing historical ledger of information, for example, accounts and transactions, into blocks.

Central bank digital currencies (CBDC)

CBDCs are currency produced by a central bank in a digital format. They can be underpinned and transacted on distributed ledger technology (DLT).


A digital asset used as a medium of exchange. Cryptocurrencies are borderless, secure, and maintained by blockchains as opposed to centralised banks or governments.

Decentralised finance (DeFi)

The ecosystem of borderless, trustless, peer-to-peer financial tools built on public blockchains without the use of banks. DeFi apps are built to be open and interconnected, allowing them to be used in conjunction with one another.

Digital assets

This includes: fungible tokens (cryptocurrencies), stablecoins, non-fungible tokens (NFTs) and central bank digital currencies (CBDC).

Digital Wallet

A software application or hardware device used to store private keys to blockchain assets and accounts. A blockchain wallet does not actually store the coins or tokens themselves but instead, they store the private key which proves ownership of the specific digital asset.

DAO (Decentralised Autonomous Organisation)

An organisation based on open-source code and governed by its users. DAOs focus on a specific project or mission and trade the traditional hierarchical systems of legacy corporations for guidelines written on the blockchain.


A public blockchain that serves as the foundation for decentralised applications. Ethereum allows users to write and deploy complex, self-executing smart contracts which live on the blockchain.

NFTs (Non-fungible token)

A digital certificate used to assign and verify ownership of a unique digital or physical asset. NFTs are not interchangeable. Examples include property, art, event tickets, governance rights, company shares.


An emergent online space with digitally persistent environments that people inhabit, as avatars, for synchronous interactions and experiences, accessing the shared virtual space through virtual reality, augmented reality, game consoles, mobile devices, or conventional computers.


A token with its value attached to another asset. Stablecoins are usually backed by a fiat currency, like the US dollar, but can also be pinned to physical assets like precious metals, or other cryptocurrencies like Bitcoin.

Smart contracts

Self-executing code deployed on a blockchain which allow transactions to be made without an intermediary figure and without the parties involved having to trust one another.

Web 3 organisation

Companies that start digital asset businesses, such as bitcoin miners, stablecoin issuers, DeFi platform providers, including decentralised autonomous organisations.

Web 1

The earliest version of the internet as the read-only web, with static pages that people could visit, but not interact with. Web 1 was named after the concept of Web 2 was developed.

Web 2

The modern version of the world wide web. Web 2 is the social web, which is driven by user-generated content.

Web 2 websites are dynamic and interactive. People can create accounts or see content specifically intended for them. Most websites would fit under Web 2.
