Token
A token is a digital unit on an existing blockchain. For example, it can be used as a means of payment, an access pass, or a way to vote in a crypto project.
What is a token?
A token uses another network’s blockchain. A coin is usually the original currency of a blockchain. For example, ETH is the coin of Ethereum, while tokens can run on Ethereum’s infrastructure.
Many tokens work with smart contracts. These are programs on a blockchain that carry out rules. For example, they can keep track of how many tokens exist and who owns them.
A crypto wallet stores the keys you use to approve a transfer. The tokens themselves are recorded on the blockchain. You often pay network fees for a transfer in that network’s original coin.
An example of a token
Suppose an application on Ethereum issues a token that lets users vote on proposals. Someone with ten tokens can send them to another user.
The blockchain then updates the balances. The transfer fee is usually paid in ETH. This shows that a token can work on Ethereum without having its own blockchain.
Why are tokens important in crypto?
Tokens are used for stablecoins, financial applications, digital collectibles, and votes within crypto projects, among other things. That’s why news often covers new tokens, exchange listings, changes in supply, or tokens being released.
A token doesn’t automatically give you a share of a company, its profits, or an underlying asset. The rights a token provides depend on its terms and legal structure.
Be aware of the risks, too. Its value isn’t guaranteed, and it may be difficult to trade. Smart contract errors, stolen keys, or an issuer’s control can lead to losses. So a token isn’t automatically decentralized.
