How Does Ethereum Work and Its Main Features?
Ethereum is an open-source blockchain platform that allows developers to build and deploy decentralised applications (dApps). Below, we detail its functionality and key features:
How Ethereum Works
Decentralised Blockchain: Ethereum operates on a decentralised blockchain network where data and transactions are stored in a shared and distributed ledger across a global network of nodes. This ensures no central entity controls the network and provides censorship resistance and high availability.
Smart Contracts: Smart contracts are self-executing programs stored on the blockchain that automatically execute when predefined conditions are met. These contracts eliminate the need for intermediaries, reduce costs, and increase efficiency in transactions and agreements.
Ether (ETH): The native cryptocurrency of Ethereum, used to pay for transactions and services within the network. Ether also acts as an incentive for miners who validate transactions and secure the network.
Ethereum Virtual Machine (EVM):Â An execution environment that processes smart contracts on the Ethereum network. The EVM allows developers to write smart contracts in various compatible programming languages and ensures these contracts execute uniformly across the network.
Proof of Stake (PoS): Ethereum is transitioning from a Proof of Work (PoW) system to Proof of Stake (PoS) with Ethereum 2.0. PoS is more energy-efficient and allows for greater scalability by reducing the need for costly and energy-intensive mining processes.
Main Features of Ethereum
Decentralisation: Ethereum is operated by thousands of independent nodes around the world, ensuring high fault tolerance and censorship resistance. There is no central point of control, making the network robust and reliable.
Security:Â The Ethereum network uses advanced cryptography to secure transactions and data stored on the blockchain. Smart contracts are also protected against tampering once deployed.
Transparency: All transactions and smart contracts on Ethereum are public and verifiable, providing a high degree of transparency. Anyone can verify the authenticity of transactions and contracts on the network.
Interoperability: Ethereum enables integration and communication with other blockchains and external systems through oracles and bridges. This facilitates the creation of applications that can interact with multiple platforms.
Flexibility: The EVM allows developers to create and deploy a diverse range of decentralised applications, from finance to gaming and governance. Ethereum's flexibility makes it suitable for a wide array of applications.

DAOstack: A framework for creating and managing DAOs, enabling communities to coordinate and make decisions in a decentralised manner.
Examples of Projects Developed on Ethereum
Uniswap
Uniswap is a decentralised exchange protocol that allows users to trade ERC-20 tokens without intermediaries. It uses an automated market maker (AMM) model to provide liquidity and facilitate trading. Users can trade tokens directly from their wallets, and liquidity providers can earn fees by contributing funds to the liquidity pool.
Aave
Aave is a decentralised lending platform that allows users to lend and borrow cryptocurrencies without needing a bank. It uses smart contracts to manage loans and ensure the solvency of the system. Users can earn interest by lending their assets and can obtain collateralised loans using their cryptocurrencies.
Cryptokitties
Cryptokitties is a blockchain-based game where players can buy, sell, and breed unique digital cats, using NFTs to represent the ownership of each cat. Each cat has unique characteristics and attributes, and players can breed new cats by combining the traits of two existing cats.
Chainlink
Chainlink is a project that connects smart contracts with real-world data through decentralised oracles. Oracles enable smart contracts to interact with external data securely and reliably, such as asset prices, sports events, and other real-world data.
Decentraland
Decentraland is a virtual world where users can buy, develop, and sell land parcels using NFTs. Decentraland combines elements of virtual reality and blockchain to create an immersive and decentralised experience. Users can build and monetise their parcels, creating interactive experiences and digital content.
Ethereum's Journey: Where It Comes From and Where It's Going
Ethereum was proposed in 2013 by Vitalik Buterin and launched in 2015. Since its launch, it has evolved significantly, transitioning from an experimental platform to critical infrastructure for decentralised applications across multiple industries.
Key Milestones in Ethereum's Journey
2015: Launch of Ethereum's mainnet.
2016: The DAO, a decentralised autonomous organisation, raises over $150 million in Ether but suffers a hack leading to a chain split, resulting in Ethereum (ETH) and Ethereum Classic (ETC).
2017: The ICO (Initial Coin Offering) boom, using Ethereum as a platform for fundraising.
2018-2019:Â Development and adoption of DeFi applications like MakerDAO, Compound, and Uniswap.
2020: Launch of Ethereum 2.0 Phase 0, introducing the beacon chain and staking.
The Future of Ethereum
The future of Ethereum looks promising with several key developments and enhancements on the horizon:
Ethereum 2.0 and Proof of Stake (PoS)
One of the most significant upgrades is the transition from Proof of Work (PoW) to Proof of Stake (PoS) with Ethereum 2.0. This upgrade aims to address several limitations of the current Ethereum network, including scalability, security, and energy efficiency.
Energy Efficiency: PoS significantly reduces the energy consumption required for network validation compared to PoW. This makes Ethereum 2.0 a more sustainable and environmentally friendly option.
Scalability: The introduction of sharding will allow the Ethereum blockchain to process many transactions simultaneously, reducing congestion and lowering transaction costs. Sharding divides the network into smaller pieces, or shards, each capable of processing its own transactions and smart contracts.
Security: PoS enhances the security of the network by requiring validators to stake their Ether as collateral. This economic incentive aligns the interests of validators with the overall health and security of the network.
Layer 2 Solutions
Layer 2 solutions are being developed to further enhance Ethereum's scalability and reduce transaction fees. These solutions operate on top of the Ethereum mainnet and include:
Rollups: Aggregates multiple transactions into a single batch, which is then recorded on the Ethereum mainnet. This significantly reduces the number of transactions that need to be processed on-chain, lowering costs and increasing throughput.
State Channels:Â Allows participants to conduct multiple transactions off-chain, with only the final state recorded on-chain. This reduces the number of on-chain transactions and increases transaction speed.
Continued Development of Decentralised Applications (dApps)
As the Ethereum ecosystem grows, we can expect to see continued innovation in dApps across various sectors, including finance, gaming, supply chain, and governance. The development of more user-friendly interfaces and improved scalability will make dApps more accessible to a broader audience, driving further adoption.
Interoperability with Other Blockchains
Interoperability between Ethereum and other blockchains will become increasingly important. Projects like Polkadot and Cosmos are working on solutions to enable seamless communication and value transfer between different blockchain networks. This interoperability will allow Ethereum to integrate more effectively with other ecosystems, expanding its use cases and utility.
Differences Between Ethereum and Bitcoin
While both Ethereum and Bitcoin are blockchain platforms, their goals and functionalities differ considerably:
Objective: Bitcoin was created as a decentralised digital currency, aimed at providing a peer-to-peer payment system that operates without the need for intermediaries like banks. Its primary use case is as a store of value and a medium of exchange. In contrast, Ethereum is designed to be a platform for decentralised applications, allowing developers to build and deploy smart contracts and dApps. While Ether (ETH) is used as a currency within the Ethereum ecosystem, its primary purpose is to facilitate operations on the network.
Flexibility: Ethereum is more flexible than Bitcoin, allowing the creation of complex smart contracts and dApps. Bitcoin's scripting language is limited and not Turing-complete, meaning it cannot support the same level of programmability as Ethereum. Ethereum's EVM supports Turing-complete programming languages, enabling developers to create a wide range of applications beyond simple financial transactions.
Consensus Mechanism: Bitcoin uses a Proof of Work (PoW) consensus mechanism, where miners solve complex mathematical problems to validate transactions and secure the network. This process is energy-intensive and has raised concerns about environmental sustainability. Ethereum is transitioning to a Proof of Stake (PoS) consensus mechanism with Ethereum 2.0, which is more energy-efficient and provides economic incentives for validators to act in the network's best interest.
Transaction Speed: Ethereum generally has faster block times than Bitcoin, enabling quicker transactions. Bitcoin's average block time is around 10 minutes, while Ethereum's average block time is around 13 seconds. This difference allows Ethereum to process transactions more rapidly, making it more suitable for applications that require high throughput.
