With the Bitcoin mining process, the miner adds transactions records to the blockchain. Enormous computing power is needed to execute this record-keeping process.
Every Bitcoin miner contributes to the decentralized peer-to-peer network to ensure that the blockchain network is trustworthy and secure. A blockchain network is a decentralized P2P network that is also a distributed ledger. It has no central authority and the miner’s network records, processes, and validates the transactions.
These transactions are completely transparent, but the personal data is anonymous. Miners are the ones who validate the blocks of transactions to get rewards. When a transaction block is added to the ledger, a new BTC is introduced to the network. So, the miners not only secure the blockchain network but also validate the transactions. To ensure that the blockchain network is working properly, miners work constantly on the network.
