Welcome back to r/CryptoCurrency Academy. In our last Lesson, we discussed the "World Computer", Ethereum, and other Smart Contract Protocols. We learned that while Bitcoin acts like a pure currency, Ethereum is also a World Computer that runs any software in a decentralized way.
Today, we explore the most famous result of that innovation: Tokens.
Tokens are a type of CryptoAssets.
The Shopping Mall Analogy
To understand tokens, imagine a giant Shopping Mall.
- The Mall (The Blockchain): This is the infrastructure. It provides security, electricity, and the rules of operation. Like Ethereum, or other Protocols.
- Cash (The Native Coin): To enter the mall or pay for general maintenance, you use the mallβs official currency (like Ether).
- Gift Cards (The Tokens): Inside the mall, specific shops can issue their own cards.
A "Coffee Shop Card" is redeemable only at the coffee shop. You cannot use it to pay the mallβs electricity bill, but within that shop, it is money.
You can also trade and sell Gift Cards on the open market, making them usable as currency sometimes.
This is how Tokens work. They do not have their own blockchain.
They are "guest assets" that live inside an existing blockchain (like Ethereum). They piggyback on the World Computer's security so they don't have to build their own.
Why Create a Token?
Before smart contracts, if you wanted to create a CryptoAsset, you had to build a "Mall" (Blockchain) from scratch. You needed servers, miners, and code. It was expensive and difficult.
With the World Computer, you can simply write a few lines of code to create a "Gift Card" (Token).
To make this efficient, developers agreed on a standard "Card Shape" (technically called ERC-20, while others also exist). Because all these tokens have the exact same technical "shape", they all fit into the same wallets and can be traded on the same exchanges automatically. This standardization caused an explosion of new digital assets.
Types of Tokens
Not all tokens are trying to be money (simple Gift Cards), though almost all tokens can be freely traded on the open market.
In the smart economy, tokens usually fall into three categories:
1. Utility Tokens (The Arcade Ticket): These act like tickets to access a specific service or product.
- Example: Imagine a cloud storage service built on the blockchain. To save a file, you must pay with their specific token. If you don't own the token, you can't use the software.
2. Governance Tokens (The Ballot): These act like voting slips.
- Example: A new kind of Company emerged called Decentralized Autonomous Organization (DAO), where Token holders have the power to vote.
3. Asset-Backed Tokens (The I.O.U.): Real World Assets (RWA) Tokenization is the process of representing something valuable in the real world with a Token on the Blockchain.
- Example: A company buys a house for $1 Million US Dollars and "tokenizes" it, by creating 1 million tokens and selling them for 1.1 USD each. Each token represents a part-ownership in that house. The company can make a profit, and people can now own a share of real-world assets on-chain. (Important caveat: a token only equals legal ownership if an off-chain legal structure enforces it, the blockchain alone does not make you the legal owner.)
Summary
- A lot of CryptoAssets have their own blockchain (Layer 1).
- Tokens: Live on top of another blockchain. They might be the currency of a specific application, or any other type of Token.
Tokens transformed crypto from a simple payment system into a complex economy of apps, voting systems, and digital assets.
But as thousands of tokens filled the mall, the hallways became crowded.
In the next lesson, we will explain Scaling: what happens when the World Computer gets too crowded, and how "Layer 2" solutions are trying to fix it.
See you in Lesson 7.
