Step 6 / What a token does
A token is easy. A useful system is hard.
Start with what a new token actually proves.
Imagine printing a thousand tickets for a theater with no show. The tickets can have a name, seat numbers, and a beautiful logo. That does not put an actor on the stage.
A crypto token can begin in the same way. Creating units is one task. Building something people want to use is another. Even when a service works, you still need to ask what owning its token lets you do.
Creating units does not create a useful service
A developer can create a token on a network such as Ethereum by using a smart contract. This is a program on the network that records balances and defines how the tokens can move.
Developers do not always start from scratch. They can reuse code built around a common set of functions called ERC-20. Wallets and apps know how to use those functions to check balances, transfer tokens, and request spending permission.
That makes a basic token easier to create. It does not make the program secure or the project useful. Building reliable software takes more work, and putting it on the network costs fees that vary with the design and network conditions.
The network checks whether the action follows its rules. It does not review the business idea for you. Neither does an attractive website, a logo, or a listing on an exchange.
A token can be created.
A useful service still needs real customers.
Check the network and the token separately
Picture a shop inside a building. The building can be sound while the shop is badly run. A token can also depend on a working network while having dangerous rules of its own.
A base blockchain checks transactions and helps participants agree on a shared record. Its own coin is called its native coin. That coin often pays network fees or has a role in securing the network.
A token contract runs on a host network and adds its own rules. For example, an administrator might be able to create, or mint, more tokens, pause transfers, freeze balances, or replace the code. A reliable host can carry out those rules exactly, even when they hurt a holder.
You will see several labels for these systems. An altcoin is broadly any cryptocurrency other than Bitcoin. Layer 1 means a base network. A Layer 2 handles activity using another set of rules while relying on a base chain to help settle it. Check what it sends to the base chain and what must be trusted separately. A Layer 2 does not have to issue its own token.
Ask what holding the token lets you do
Now imagine the theater succeeds and sells out. Its separate token lets holders vote on next year’s shows. It does not give them a seat or a share of ticket sales.
The theater is busy, but customers can still buy tickets without that token. The business’s success has not explained why people would want to buy and hold the voting token.
Finish this sentence for any token: “Holding it lets its owner…” Voting, using a service, and receiving part of its revenue are different rights. If the only reason you can find is a hope of selling it for more, write that down plainly.
Then ask where that right comes from. Read the actual rules rather than guessing from a category or a name. A useful service and a good purchase for its token holder are separate questions.
A few common token categories
Some DeFi tokens give votes over a financial app. Stablecoins aim to follow a reference value, such as a currency; their backing, issuer, and design still matter. A stable target does not guarantee that you can redeem a token when needed.
Meme coins build around a joke or community, often with buyers focused on future price. Privacy coins use designs intended to hide some transaction details, with different limits and access rules. Categories can overlap. None tells you all the rights or risks of a particular token.
Look for the link between use and demand
Attention may bring people through the theater’s door once. What would make them return? For a token, ask why someone would keep wanting it after launch rewards and publicity end.
A small supply alone does not create buyers. Connect the number of units with what they let holders do and why people would pay for that right.
A white paper explains a project’s proposal or argument. Check which parts already exist, whether people use them, and whether using the product requires or benefits the token. A promise about future work is different from evidence of work already done.
The aim is to investigate fairly. Separate what exists from what is promised, then separate the product’s usefulness from what its token gives a holder.
The idea to keep
Start with three things: what has been built, which network it depends on, and what rights the token actually grants. A name and a supply are the beginning of the investigation.
Next, put the quoted price beside the number of units.
