When mining is done by a single person, user registration as a miner is required. As soon as a transaction is completed, each user in the blockchain network is assigned a mathematical problem to solve. The person who figures it out first wins a prize.
When the solution is found, the encrypted value is verified by every other miner in the blockchain network before being added to the blockchain. As a result, the transaction is confirmed.

Individual mining refers to the process of cryptocurrency mining carried out by a single person or entity using their own hardware and resources. In this method, individuals set up their own mining rigs or use specialized mining equipment to validate and process transactions on a blockchain network, such as Bitcoin or Ethereum.

Individual miners contribute their computing power to solve complex mathematical puzzles, known as Proof of Work (PoW), in order to add new blocks to the blockchain and receive rewards in the form of newly minted cryptocurrency coins or transaction fees.

While individual mining can be accessible to anyone with the necessary hardware and technical knowledge, it requires significant investment in equipment, electricity, and cooling systems. Additionally, the increasing difficulty and competition in cryptocurrency mining make it challenging for individual miners to remain profitable compared to large-scale mining operations known as mining pools. Nonetheless, individual mining remains an important aspect of decentralized blockchain networks, promoting network security and decentralization.
