How Does Ethereum Work?
Ethereum operates on a decentralized network of computers that collectively maintain a blockchain. This network is composed of nodes, which are responsible for validating transactions and executing smart contracts. To understand how Ethereum works, let’s dive into its key components and processes.
1. Blockchain: Ethereum’s blockchain is a distributed ledger that records all transactions and smart contract executions. It consists of a series of blocks, with each block containing a list of transactions. The blockchain is maintained and synchronized across all participating nodes in the network.
2. Nodes: Nodes are computers or devices that connect to the Ethereum network. There are two types of nodes: full nodes and light nodes. Full nodes keep a complete copy of the blockchain and process all transactions and smart contracts. Light nodes, on the other hand, only store and verify specific parts of the blockchain, relying on full nodes for additional information.
3. Smart Contracts: Smart contracts are self-executing agreements written in Solidity, Ethereum’s programming language. They automatically execute predefined actions when certain conditions are met. Smart contracts are stored on the blockchain and are accessible to anyone on the network. They enable the creation of decentralized applications and facilitate trustless interactions between parties.
4. Ethereum Virtual Machine (EVM): The Ethereum Virtual Machine is a decentralized computer that runs on every node in the network. It executes smart contracts and ensures their consistency across all nodes. The EVM provides a secure and deterministic environment for executing code, making Ethereum a reliable platform for building and deploying decentralized applications.
5. Gas: Gas is a measure of computational effort required to execute operations on the Ethereum network. Every operation, such as a transaction or smart contract execution, consumes a specific amount of gas. Gas fees are paid in Ether and serve as an incentive for nodes to process transactions and execute smart contracts. The gas limit determines the maximum amount of computational work allowed per block.
6. Mining: Ethereum initially relied on a Proof of Work (PoW) consensus algorithm, similar to Bitcoin. Miners compete to solve complex mathematical puzzles in order to validate and add transactions to the blockchain. However, Ethereum is transitioning to a Proof of Stake (PoS) consensus mechanism through Ethereum 2.0. PoS eliminates the need for miners, as validators with a stake in Ether secure the network by participating in the consensus process.
7. Upgrades and Hard Forks: Ethereum regularly undergoes upgrades and improvements to address scalability, security, and sustainability concerns. These upgrades are implemented through hard forks, which are backward-incompatible changes to the protocol. Notable upgrades include the London hard fork that introduced the EIP-1559 fee structure, and the upcoming Ethereum 2.0 upgrade, which aims to improve scalability and energy efficiency.
By leveraging its decentralized network, smart contracts, and the Ethereum Virtual Machine, Ethereum provides a secure and adaptable platform for developers to build innovative decentralized applications.
