Token are not digital coins. Tokens are created on existing blockchains. The most common blockchain token platform is Ethereum and tokens from this platform are known as ERC-20 tokens.

There are also other tokens such as NEO, Waves, Lisk, and Stratis. NEO uses tokens known as NEP-5 tokens.

Creating a token takes little technical ability, but it requires the developer to spend some native coins to the blockchain on which the token is being created.

For example, a creator will need to spend some Ether to create a token on Ethereum. This is used to get the miners to validate the token transaction.

Most tokens are used with decentralised applications (dApps). When developers create their tokens, they can be used to activate features of the application they were designed for.

Some tokens are created to represent a physical thing. If you want to sell your house using a smart contract, you can't physically put your house into the smart contract, but you can use a token that represents your house.

For example, WePower (WPR) uses a token that represents electricity. Users can buy and sell electricity on the blockchain using smart contracts.

Tokens are used to interact with decentralised applications that are built on top of different blockchains.

For example, Civic (CVC) is an application that keeps track of encrypted identities on the Ethereum blockchain. If you were to go on a foreign holiday, you'd need to confirm your identity repeatedly along the way, such as the airline, hotel, etc. If they are a partner of Civic, they can quickly identify you at various points. The CVC token is used for the transaction.

• Security Tokens. Most tokens issued by Initial Coin Offerings (ICO) are security tokens. This is because the buyer invests their money in the ICO expecting a profit.
• Equity Tokens. It represents some stock or equity in the company that issues it.
• Utility Tokens are also known as application tokens. They are used to give people access to either a product or service. They are rare as most tokens are expected to gain in value.
• Payment Tokens only serves to pay for goods and services.
