Module 7 — Tokens
Everything so far has been groundwork for this: understanding tokens. Tokens are how value, access, and ownership get represented on a blockchain — and they're built directly on the smart contracts we just learned about. This module covers what tokens are and the many different kinds that exist.
7.1 What is a token?
A token is a unit of value or rights that exists on a blockchain. That value can mean many things: money-like value, access to a service, voting power, ownership of an item, or points you can spend inside an app. A token is essentially an entry in a ledger that says "this address holds this much of this thing," governed by rules.
The key insight: a token doesn't have to represent money. It can represent almost anything that's useful to count, own, or transfer — as long as everyone agrees the blockchain's record of it is the truth.
7.2 A token is a smart contract
Here's the connection to Module 6, and it's the most important idea in this module:
Most tokens are not separate magical objects — a token is defined by a smart contract. The contract is the rulebook that says how many tokens exist, who holds them, how they can be transferred, and what happens when they move.
When you "send a token," you're really calling the token's smart contract and asking it to update its records: subtract from your balance, add to the recipient's. The contract enforces the rules — you can't send more than you have, you can't forge someone else's balance — automatically and identically for everyone. This is why understanding smart contracts first made tokens easy to understand: a token is just a particularly useful, standardized kind of smart contract.
7.3 Coins vs tokens — a quick distinction
People mix these up constantly:
- A coin is the native currency of its own blockchain — it's built into the chain itself and is typically used to pay for using that network.
- A token is created on top of an existing blockchain via a smart contract — it rides on infrastructure it didn't build.
Analogy: if a blockchain were a country, the coin is its official national currency, while tokens are like gift cards, loyalty points, and vouchers issued by businesses operating inside that country. They all have value, but they originate differently.
7.4 The main types of tokens
Tokens come in several flavors depending on what they're designed to do.
7.4.1 Utility tokens
Tokens that give you access to a product or service — like a ticket or an arcade token. You use them to do something within a platform, not primarily to invest. Their value comes from how useful the underlying service is.
7.4.2 Security / asset tokens
Tokens that represent an investment or ownership stake in an external asset (like shares, real estate, or revenue). Because they resemble traditional financial instruments, they're typically the most heavily regulated type. They promise some financial return tied to an underlying asset.
7.4.3 Governance tokens
Tokens that grant voting rights over how a project or protocol is run. Holding them is like holding votes: you can help decide on changes, budgets, or rules. They turn users into stakeholders in decision-making.
7.4.4 Stablecoins
Tokens designed to hold a steady value, usually by being pegged to something stable like a national currency. Their goal is to combine the convenience of a token with the predictability of regular money — useful for payments and as a "calm" place to park value.
7.4.5 Non-fungible tokens (NFTs)
Tokens where each one is unique and not interchangeable. While one ordinary token is identical to another (like identical coins), each NFT is one-of-a-kind — used to represent ownership of a specific item, like a piece of digital art, a collectible, or a unique in-game asset.
7.4.6 In-app / ecosystem tokens
Tokens that work as points or currency inside a specific app or family of apps — think of the coins or gems in a game. You earn them and spend them within the ecosystem, and they're usually not designed to be cashed out into regular money. Their purpose is to power activity inside the platform: rewards, transfers between users, and access to features.
This last category is especially common in consumer products. An ecosystem like Tupic uses an in-app token (TPDT) of exactly this kind — earned and spent across its services, functioning like in-app credit rather than cash. We'll look at that example closely in Module 9.
7.5 Tokenomics in plain language
Tokenomics = the economics of a token: how it's created, distributed, and used, and what gives it value. The core levers:
- Supply: How many tokens exist? Is the amount fixed or growing? Scarcity can influence value, but only if there's genuine demand.
- Demand / utility: Why would anyone want this token? A token people actually need (to use a service, to play a game, to vote) has a reason to be valued. A token with no real use relies purely on speculation — which is fragile.
- Distribution: Who got the tokens, and how fairly? A token concentrated in a few hands behaves differently from one spread widely among real users.
- Use case: What can you actually do with it? This is the foundation everything else rests on.
The single healthiest signal in tokenomics is real utility: a token that does something useful for real users. A token whose only "use" is hoping someone pays more for it later is exactly the kind of thing we'll learn to be cautious about in Module 8.
Key takeaway: A token is a unit of value defined by a smart contract. Tokens come in many types — utility, security, governance, stablecoins, NFTs, and in-app ecosystem tokens. What gives a token lasting value isn't hype or scarcity alone, but genuine utility for real users.
