Ethereum (إيثيريوم) is one of the most prominent cryptocurrencies and decentralized platforms in the blockchain world, ranking second in market capitalization after Bitcoin. Ethereum is not just a digital currency (called Ether - ETH), but a complete blockchain network that allows developers to build and deploy decentralized applications (dApps) and smart contracts. This ability to run code autonomously without the need for an intermediary distinguishes Ethereum and opens the door to countless innovations.

Ether (ETH) acts as "fuel" for the Ethereum network, as it is used to pay transaction fees (gas fees) and to execute smart contracts. Ethereum has evolved significantly since its launch in 2015 and has seen several important upgrades, most notably the transition from Proof of Work (PoW) to Proof of Stake (PoS) in "The Merge." This upgrade has greatly reduced the network's energy consumption and made it more efficient and sustainable.

Ethereum is widely used in various fields such as decentralized finance (DeFi), non-fungible tokens (NFTs), decentralized gaming, and supply chain management. Thanks to its active community and developers spread around the world, Ethereum continues to evolve and innovate, making it a cornerstone in building a decentralized and open digital economy. Challenges such as scalability and high gas fees have existed in the past,
