1. Miners in the Bitcoin network perform several critical functions : • Transaction Validation : Miners validate transactions to ensure that they adhere to the Bitcoin protocol . This involves checking that the sender has sufficient funds and that the transaction is correctly formatted. • Block Creation : Once transactions are validated, miners group them into a "block." • Proof of Work : Miners compete to solve a complex mathematical puzzle, a process known as " proof of work ." The first miner to solve the puzzle gets to add their block to the blockchain and is rewarded with newly minted bitcoins and transaction fees. • Securing the Network : By participating in the proof of work process, miners secure the network against double-spending and other types of attacks. The computational power required to solve the puzzle makes it prohibitively expensive for attackers to alter the blockchain . • Consensus Mechanism : Miners help maintain the decentralized natur...
