Crypto tokens are digital assets built on top of an existing blockchain rather than serving as that network’s native currency. In the source material, Bitcoin and Ethereum are presented as examples of coins with their own blockchains, while tokens are described as assets created through smart contracts and used to represent fungible assets, tradable assets, and utilities.
The article argues that tokens expanded what crypto networks could do. Instead of limiting blockchain activity to peer-to-peer transfers, the ecosystem now supports services that resemble lending, savings, and insurance. In that framework, tokens act as the asset layer that allows those applications to function on-chain.
How tokens differ from native crypto coins
The source draws a clear line between coins and tokens. Coins are native to the blockchain they belong to. Tokens are not native to the base chain; they operate within smart contracts deployed on that chain. The piece cites Tether, MakerDAO, and Aave as examples of protocols or tokenized assets on Ethereum.
The transfer logic is also different. When coins move, the result is described as an update to wallet balances. The article uses 5 BTC as an example: one balance goes down by 5 BTC and another goes up by 5 BTC. Tokens, by contrast, are framed more directly as digital assets being transferred from one wallet to another. NFTs are the clearest case, because they represent ownership of a specific asset rather than a generic balance entry.
The source also separates them by what they represent. Coins function as digital units of value, while tokens can stand for ownership of digital or real-world assets. A user may spend coins to buy tokens, but the amount paid depends on the value of the underlying asset. Some token types, especially NFTs, also differ from coins in terms of liquidity.
DeFi, governance, and NFTs are major token use cases
By function, the article groups tokens into utility tokens and security tokens. By feature, it distinguishes fungible tokens from non-fungible tokens. That structure shows how broad the token category has become inside crypto markets.
In DeFi, tokens are used for lending, crypto savings, insurance, trading, and generating passive income. The article also notes that investors may hold tokens as a store of value, much like other crypto assets. In this setting, a token is not just a payment instrument; it can also be part of how a protocol operates and distributes value.
Governance tokens are tied to decision-making in decentralized projects. The source says crypto projects can be viewed as DAOs, where governance is not held by a central authority. Participants usually need to hold a project’s token to vote on protocol changes or upgrades. MakerDAO is used as the example: holders of MKR can vote on upgrades to the MakerDAO smart contract, and more tokens generally mean more voting power.
The difference between fungible tokens and NFTs is presented in practical terms. One DAI can be swapped for another DAI because each unit serves the same function. NFTs do not work that way. They represent ownership rights to unique digital or real-world assets. The article points to CryptoPunks and notes that even though there are 10,000 avatars in the collection, one cannot simply be exchanged for another as if they were identical units.
Security tokens and where users get tokens
Security tokens are described as one of the more ambitious token categories in crypto because they aim to mirror traditional securities such as stocks and shares on-chain. The source says these tokens became especially visible in 2017, when crypto companies used ICOs to raise capital. In the article’s explanation, an ICO resembles startup fundraising, except investors contribute cryptocurrency instead of fiat and receive ownership rights comparable to shares or fractional shares.
As for access, the source says the most common place to get tokens is through cryptocurrency exchanges. Exchanges can support trading between tokens, coins, and fiat currencies, while also helping users manage balances, check token values, and send or receive assets.
The central takeaway is straightforward. Tokens are not just another word for coins. They are smart-contract-based assets that connect blockchain applications with ownership, utility, and governance across DeFi protocols, NFT markets, and token-based fundraising models.
