Bitcoin mining is the process of creating new bitcoins by solving complex mathematical puzzles. Bitcoin miners are rewarded with newly created bitcoins and transaction fees for their work.
Mining is a critical component of the bitcoin protocol because it ensures the security of the blockchain and allows new transactions to be added in a trustless manner. Miners are also responsible for maintaining the decentralized network by approving bitcoin transactions.
Mining is a computationally intensive process that requires a lot of energy and specialized hardware. As a result, it has become increasingly centralized as large companies have invested in expensive mining rigs.
This centralization has led to concerns about the security and future of the bitcoin network. Some believe that mining pools and companies have too much power over the network and could potentially collude to 51 percent attack the bitcoin blockchain.
Despite these concerns, there is no evidence that mining is illegal. In fact, it is an essential part of the bitcoin protocol and without it, the network would not function correctly.
