#CryptoSecurity101 Ethereum is like a gigantic global computer that anyone can use to create and run applications that operate without any central authority controlling them. Think of it as a platform where you can build digital services that work exactly as programmed, without the possibility of interruptions, censorship, or external interference. The system uses its own currency called Ether to pay for the use of the network. Since its creation, Ethereum has grown to become the leading platform for decentralized applications (dApps) and decentralized finance (DeFi). This revolutionary technology has transformed our way of thinking about digital ownership and online transactions.
