Ethereum is a decentralized blockchain platform that enables developers to build and deploy smart contracts and decentralized applications (dApps) without relying on a central authority.
This decentralization is a key feature that provides enhanced security and censorship resistance.

Ether (ETH) is the native cryptocurrency of the Ethereum platform and is used to facilitate transactions and execute smart contracts.
The use of ETH helps to ensure that the network remains secure and operational, as it incentivizes participants to validate transactions.
Vitalik Buterin, one of the co-founders of Ethereum, initially proposed the idea of a blockchain platform capable of supporting smart contracts in 2013.
His vision has since transformed into one of the most widely used blockchain protocols in existence.
Unlike Bitcoin, which primarily serves as a digital currency, Ethereum's design allows for programmability through smart contracts.
This opens up possibilities for various applications, including decentralized finance (DeFi), NFTs (non-fungible tokens), and more.
The Ethereum blockchain uses a consensus mechanism known as Proof of Stake (PoS) following its upgrade to Ethereum 2.0, which improves scalability and reduces energy consumption compared to the previous Proof of Work (PoW) model.
The transition to PoS means that instead of miners solving complex mathematical problems to validate transactions, validators are chosen based on the amount of ETH they are willing to "stake" or lock up as collateral.
Ethereum has experienced significant upgrades since its launch, with the most notable being the transition to Ethereum 2.0 that began in late 2020 and is aimed at increasing transaction throughput and network efficiency.
The Ethereum network can process around 30 transactions per second, a figure that is significantly lower compared to traditional payment providers like Visa, which can handle thousands of transactions per second.
However, upcoming upgrades aim to increase this capacity dramatically.
Gas fees are transaction fees paid by users to compensate for the computational energy required to process transactions on the Ethereum blockchain.
These fees can vary significantly based on network congestion and demand, which is a critical factor for potential investors to consider.
The maximum supply of ETH is not capped like Bitcoin, offering a different monetary policy.
Instead, it is designed with an inflationary model to support the network's security and sustainability in the long term.
Ethereum has a robust developer ecosystem, supporting thousands of dApps and protocols across diverse sectors such as finance, gaming, and supply chain management.
This level of developer activity fuels innovation and potential for growth.
Smart contracts on Ethereum operate as self-executing contracts with the terms directly written into code, which helps eliminate the need for intermediaries and can increase efficiency and trust between parties.
The introduction of ERC-20 tokens on Ethereum allows for the creation of fungible tokens, enabling projects to raise funds through Initial Coin Offerings (ICOs) and laying the groundwork for countless DeFi services.
Ethereum's structure supports decentralized organization concepts such as DAOs (Decentralized Autonomous Organizations), which enable governance decisions to be made collectively among stakeholders via smart contracts.
The Ethereum platform allows for interoperability with other blockchains, enabling cross-chain operations, which enhances the functionality and potential use cases of applications built on both Ethereum and other platforms.
Ethereum's transition to a Proof of Stake model is projected to decrease energy consumption by over 99%, contrasting sharply with its previous PoW model, which drew criticism for environmental concerns related to high energy use.
Developer interest in Ethereum has led to the development of Layer 2 solutions, such as Optimistic Rollups and zk-Rollups, which further enhance scalability and reduce transaction costs while leveraging the security of the Ethereum mainnet.
Unlike traditional finance systems, which rely on banks and intermediaries, Ethereum operates on a permissionless basis, allowing anyone to interact with its protocols, thereby democratizing access to financial services.
