How are you? By Allah's grace, I'm doing very well.

Although the terms token and coin are often used interchangeably in the cryptocurrency ecosystem, there are important technical and practical differences between them. This difference mainly depends on which blockchain they operate on and what their purpose is.

1. What is a coin?

A coin is a type of cryptocurrency that operates on its own, independent blockchain platform and its main purpose is to act as a form of money. A coin has its own underlying layer 1 blockchain, for example: Bitcoin has its own blockchain (Bitcoin blockchain). Ethereum also has its own blockchain (Ethereum blockchain). Coins are primarily designed to be a store of value, a medium of exchange, and a unit of account. This currency is used to pay transaction fees (Gas Fee) or to secure the network (such as mining or staking). Bitcoin (BTC): The main means of storing value. Ether (ETH): Used as the gas fee of the Ethereum network and as computing power in the Ethereum Virtual Machine (EVM). Solana (SOL), Cardano (ADA): These are the native currencies of their respective networks.

2. What is a Token?

A token is a type of cryptocurrency that is built using smart contracts on top of another existing blockchain. The token does not have its own blockchain; it relies on the security and functionality of its host platform. Most tokens are built on smart contract-enabled blockchains like Ethereum (such as Ethereum's ERC-20 standard). Tokens are designed to serve a specific purpose or utility rather than money. The creation, issuance, distribution, and management of tokens are all controlled by a smart contract. This is why transaction fees are paid in the currency of the underlying blockchain (such as ETH).

Types and Examples

Understanding the difference between tokens and currencies is important, as it helps investors assess the inherent risk, utility, and technical reliance of the asset.
