What is Token?
Crypto Glossary Definition
A cryptocurrency that relies on another cryptocurrency (such as Ethereum) in order to operate. A token does not have a blockchain of its own.
Why Token Matters
Tokens are built on top of an existing blockchain (like Ethereum's ERC-20 standard) rather than having their own independent chain, the way Bitcoin or Ethereum's own coin (ETH) do. This is why launching a new token is far faster and cheaper than launching a new blockchain from scratch.
Token in Practice
A gaming studio wants to launch an in-game currency that players can earn and trade, but building an entirely new blockchain from scratch would require recruiting a network of validators, securing consensus, and convincing exchanges to support a brand-new base-layer asset, a massive undertaking. Instead, the studio deploys a token using Ethereum's ERC-20 standard, writing a smart contract that defines the currency's total supply, transfer rules, and balance tracking, all while relying on Ethereum's existing validators to secure every transaction involving it. Because the token rides on top of Ethereum rather than needing its own blockchain, the studio can deploy it in a matter of days rather than months, and it's instantly compatible with any wallet or exchange that already supports ERC-20 tokens, without those platforms needing to build any new infrastructure. Players start earning the token by completing in-game quests, then trade it on a decentralized exchange for ETH or a stablecoin, all of it settling on Ethereum even though the token itself has nothing to do with Ethereum's own coin. This is the core distinction the studio's community team ends up explaining constantly: their token is not a competing blockchain to Ethereum, it's an asset that depends entirely on Ethereum's blockchain continuing to run underneath it.
