Ethereum runs on blockchain technology, a decentralized network, where all computers share the same ledger (record) of transactions ordered according to when they happened. Each block is like a page in a ledger book. And each page links to the next, hence, a “blockchain.” These blocks go all the way back to the first “Genesis block”. Miners are special computers who use electricity and computing power to verify transactions on the blockchain. Since this uses real world resources, Ethereum rewards miners with its native token, called Ether.
