Understanding Cryptocurrencies – How Crypto Works
To understand Ethereum, it’s essential to grasp the concept of cryptocurrency. Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. Unlike traditional fiat currencies, cryptocurrencies are decentralized, meaning they are not controlled by any central authority, such as a government or central bank.
Cryptocurrencies are always part of a DAO, a decentralized autonomous organization. Such as Bitcoin, Ether, Dogecoin, and others. They work like digital money. It’s controlled by a computer network (nodes). They rely on blockchain technology, which is a public digital ledger that records all transactions. When you send or receive cryptocurrency, the network verifies and adds your transaction to this ledger.
Here’s how peer-to-peer works: Internet – Wallet – Token – Mining
- You have a digital wallet to store your cryptocurrency, like a virtual bank account.
- To send crypto, you create a digital peer-to-peer message that includes your and the counterpart’s wallet address, with the amount.
- Verification is automatically done through a network of computers (nodes).
- Once verified, the transaction is added to a chain of other blocks, forming the blockchain.
- It is super secure because of decentralization, the use of complex math, and cryptography.
Now, that you know what is Ethereum and how crypto works, we can continue to dive into the amazing world of the Ethereum blockchain.

How Does Ethereum (ETH) Work?
How Ethereum works is the second important question after what is Ethereum, right? So let’s dive into it.
It operates through various types of accounts, including externally owned accounts and contract accounts. These contract accounts are controlled by smart contracts, which are self-executing agreements encoded on its blockchain. The virtual machine (EVM) executes the code of these smart contracts and facilitates transaction processing throughout the network.
Role of Accounts
Externally owned accounts play a significant role in the network as they hold ether and enable users to interact with the system. These accounts are controlled by private keys, and through them, individuals can participate in transactions and engage with various applications running on the blockchain. On the other hand, contract accounts hold and execute smart contracts, which are self-executing agreements encoded on the Ethereum blockchain. By sending transactions, accounts interact with each other, triggering the execution of smart contract codes on the network.
Functionality of the Virtual Machine
The Ethereum virtual machine (EVM) serves as a runtime environment for executing smart contracts within the network. Its main purpose is to provide a secure and isolated space. Code can be executed without any interference or malicious activities. To ensure security, developers write smart contracts using high-level programming languages like Solidity, which are then compiled into EVM bytecode. This bytecode is what the EVM actually executes.
Understanding ‘Gas’ in Ethereum
Gas is a crucial concept in Ethereum circulation. What is Ethereum again? Right, a blockchain and it needs Gas to run. Therefore, Gas determines the computational power needed to execute transactions on the network. When users initiate transactions, they pay gas fees in Ether, creating an incentive for miners to prioritize their transactions. Gas limits are in place to prevent malicious actors from carrying out resource-intensive operations that could harm the network. By optimizing gas usage, users can reduce transaction costs and improve efficiency. Understanding gas is essential for estimating transaction fees and optimizing the execution of smart contracts. It ensures smooth and cost-effective interaction within the ecosystem.
