Transaction Collection: Miners collect a batch of pending BTC transactions, typically every 10 minutes, and bundle them into a block for validation before adding it to the Bitcoin blockchain.
Cryptographic Linking: Each block contains a unique digital fingerprint, known as a cryptographic hash, that links it to the previous block, forming a chain. Miners must create a valid hash for the new block, which involves solving a complex mathematical puzzle that requires significant computing resources.
Puzzle Resolution: The main challenge in mining is to find a hash that meets the required difficulty level of the network, a standard that is adjusted every 2016 blocks (approximately every two weeks) to ensure that the average time to find a block remains around 10 minutes. Specialized hardware, such as ASICs, play a crucial role in solving this puzzle by performing calculations at incredibly high speeds.
Proof of Effort: Successfully generating a hash that meets the difficulty criteria serves as proof of work, demonstrating the significant computational effort invested. Once a valid hash is found, the new block is added to the blockchain.
Rewards and Fees: The miner who discovers the valid hash is rewarded with newly minted Bitcoins (the block reward) and transaction fees from the transactions included in the new block.
Optimization through Collective Power: Bitcoin farms streamline this process by harnessing the collective power of multiple ASIC miners simultaneously. This coordinated effort not only increases the likelihood of finding the next block, but also improves the security and reliability of the BTC network by spreading the proof of work across many miners.

In essence, Bitcoin farms play a crucial role in verifying transactions and maintaining the decentralized nature of the cryptocurrency system.
