Yes, you can mine Ethereum on an Intel GPU. Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference.
Ethereum is mined using a Proof of Work (PoW) algorithm. Miners compete to solve complex mathematical problems in order to validate transactions and add new blocks to the blockchain.
In return for their work, miners are rewarded with Ether, the native cryptocurrency of the Ethereum network.
Intel GPUs are well-suited for mining Ethereum. They offer good performance and are relatively power-efficient.
However, they are not the most powerful GPUs on the market and you may have to mine at a lower hash rate than with other types of GPUs.
