- 01What is Ethereum?ENEthereum is a public blockchain that records balances and also runs programs called smart contracts. Anyone can use it or build on it without asking permission. Its own currency, ether (ETH), pays the fee for every action. Since 2022 the network has been secured by proof of stake instead of mining.
- 02What is a smart contract?ENA smart contract is a program stored on a blockchain such as Ethereum. It holds funds and follows fixed rules: when someone calls it and the conditions are met, it acts automatically, with no company in the middle. It cannot see outside data on its own, and a bug can lose money for good.
- 03What is a dApp?ENA dApp, short for decentralized application, is an app whose core rules run as smart contracts on a blockchain instead of on a company's servers. You use it through a website and a crypto wallet that signs each action. No company holds your funds, so contract bugs, fake sites and fees are yours to manage.
- 04What is ether, and why does it have value?ENEther (ETH) is the native currency of the Ethereum network. Every transaction pays its fee in ether, and validators lock it up as a deposit to secure the network. Its value comes from that demand meeting a supply with no fixed cap, which grows through new issuance and shrinks when fees are burned. Nothing guarantees its price.
- 05What moves the price of ether?ENEther's price moves when the balance between buyers and sellers shifts. Most days the biggest driver is the crypto market as a whole, led by bitcoin, which in turn reacts to interest rates and risk appetite. Ether's own supply, use of the network, fund flows and forced selling by leveraged traders add moves on top.
