Examining mining in Eth 1.0
In this section, we will explain how mining works in Ethereum. Depending on the progress of Eth2 and the merge of Eth 1 and Eth 2, sing the PoW consensus in mining might already be decommissioned by the time you read this section.
The mining process in Ethereum is largely the same as the one we discussed for Bitcoin. For each block of transactions to be added to the Ethereum blockchain and the world state to be updated, a consensus must be reached between all network nodes that the new blocks proposed by the miners, including the nonce found with the PoW, must be verified by all nodes.
However, there are quite a few notable differences between Ethereum mining and Bitcoin mining. Most of them are driven by the protocol and architectural differences in the blockchain. As we discussed earlier, Ethereum maintains both the transaction list and the world state on the blockchain. We will discuss those differences in detail here.
