What are ERC-20, Gas, Ether, and Ethereum

Understanding ERC-20, Gas, Ether, and Ethereum

If you are interested in the world of cryptocurrencies, chances are you have come across terms like ERC-20, gas, Ether, and Ethereum. These terms are essential components of the Ethereum blockchain, which has gained significant popularity and recognition in recent years. In this article, we will explore what ERC-20, gas, Ether, and Ethereum are, and how they are interconnected.

What is Ethereum?

Ethereum is a decentralized platform that allows developers to build and deploy smart contracts and decentralized applications (DApps). Unlike traditional centralized systems, Ethereum operates on a blockchain, which is a distributed ledger that records all transactions across a network of computers.

What is ERC-20?

ERC-20 is a technical standard for tokens on the Ethereum blockchain. ERC stands for “Ethereum Request for Comments,” and 20 is the unique identifier assigned to this particular token standard. ERC-20 tokens are fungible, meaning that each token is equal to another token of the same value, and they can be easily exchanged on decentralized exchanges.

What is Gas?

Gas is the unit of measurement used to calculate the amount of computational effort required to execute transactions or perform actions on the Ethereum network. Every operation on the Ethereum network, such as sending Ether or executing a smart contract, requires a certain amount of gas. The purpose of gas is to prevent spam and abuse of the network by imposing a cost on each operation.

What is Ether?

Ether (ETH) is the native cryptocurrency of the Ethereum network. It is used to pay for the computational power, storage, and bandwidth required to perform actions on the network. Ether can be purchased, sold, or used to interact with decentralized applications (DApps) and smart contracts within the Ethereum ecosystem.

How are ERC-20, Gas, Ether, and Ethereum interconnected?

ERC-20 tokens are created and exist on the Ethereum blockchain. To perform any transaction involving ERC-20 tokens, such as sending or receiving tokens, a certain amount of gas is required. Gas is paid in Ether, the native cryptocurrency of the Ethereum network. So whenever you want to interact with ERC-20 tokens, you need to have enough Ether to cover the gas cost.

Let’s understand this with an analogy: Imagine you are driving a car (Ethereum network) and you want to travel from one place to another. The gas is the fuel required to operate the car and make it move. Ether is like the gas station where you fill your car’s tank before starting the journey. Similarly, the Ethereum network requires Ether (gas) to execute transactions and perform actions.

When you want to send ERC-20 tokens to someone, you initiate a transaction on the Ethereum network. This transaction requires a specific amount of gas, which is specified by the Ethereum network itself. The higher the complexity and computation required by the transaction, the more gas it will consume. And as we mentioned earlier, gas is paid in Ether.

So, in summary:

  • Ethereum is the decentralized platform that allows the creation of smart contracts and decentralized applications.
  • ERC-20 is the standard for tokens on the Ethereum blockchain, facilitating the creation and functionality of tokens.
  • Gas is the unit of measurement for computational effort on the Ethereum network, paid in Ether.
  • Ether is the native cryptocurrency of the Ethereum network, used for transactions and interactions.


Understanding ERC-20 tokens, gas, Ether, and Ethereum is crucial for anyone wanting to explore the world of decentralized applications and cryptocurrency transactions. ERC-20 tokens allow developers to create and operate tokens on the Ethereum blockchain, while gas ensures the secure and efficient execution of transactions. Ether, as the native cryptocurrency, plays a vital role in covering gas fees and enabling interactions within the Ethereum network. By grasping these concepts, you will have a solid foundation to navigate the exciting realm of Ethereum and its associated technologies.
