Token

While cryptocurrency coins are native assets of a specific blockchain, cryptocurrency tokens are created by projects built on top of already existing blockchains. For example, Ether (ETH) is categorised as a coin because it represents the native asset on the Ethereum blockchain. However, Dai (DAI), Uniswap (UNI), and Aave (AAVE), for example, are classified as tokens because they are projects built on top of the Ethereum blockchain.

Cryptocurrency tokens are created using a set of token standards specific to each blockchain. These token standards are essentially technical specifications, like a set of rules to follow. For example, token standards issued on the Ethereum blockchain include ERC-20, ERC-721, ERC-777, and ERC-1155.

Tokens run on software protocols (composed of smart contracts) and generally outline the features, functions, and type of engagement with the network. Due to this, developers have since created different types of cryptocurrency tokens for specific use cases. These include DeFi tokens, governance tokens, non-fungible tokens (NFTs), and security tokens.

DeFi, short for decentralised finance, refers to financial systems built on blockchain technology. Each DeFi ecosystem has its own token that allows for a wide variety of functions and can often be traded like any other cryptocurrency. Examples include Aave (AAVE), Uniswap (UNI), and Compound (COMP).

Governance tokens are specialised DeFi tokens that give the holder certain rights, such as voting power. Commonly, the more tokens a user has, the more voting power. Examples include Maker (MKR), Curve DAO Token (CRV), and Decred (DCR).

Non-fungible tokens (NFTs) are a form of crypto tokens that represents ownership rights to a unique asset. NFTs are most commonly associated with specific digital artworks or virtual assets. Examples include CryptoPunks, Doodles, and Loaded Lions.

Security tokens are traditional securities, such as stocks, converted into digital tokens on a blockchain. Owners of these tokens also own part of the company in which they’ve invested. Examples include Blockchain Capital, tZERO, and INX.
