Miners serve the critical function of expanding the blockchain through the use of new blocks, which makes it possible to sustain and make coherent lateral shifts in Bitcoin’s transaction record. The mining process employs Proof of Work (PoW) as a mechanism for agreeing on the new ledger, whereby miners rely on powerful computer systems to solve challenging cryptographic algorithms that have been especially carefully designed to consume large amounts of computational power and electricity. Consequently, every time a miner solves the puzzle, they are capable of assembling a new piece consisting of valid transactions and presenting the point for communication within the network.
This was and still is the function of this block and all other subsequent ones up to some point and the block that did such is said to confirm the blockade. First, this blocks any possibility of fraud or double-spending of a Bitcoin that can be used by recording on the blockchain all transactions. Moreover, there is fierce competition amongst miners to crack the PoW puzzles and seek PoW solutions. From this practice, there will only be a limited number of attempts at block reconstruction because redoing a block – the previous one and the one only is profitable to the attacker.
Miners earn these through receiving new bitcoins (the “block reward”) and transaction fees charged to network users. In fact, this is what will put additional bitcoins into the market, a slow drip of them, seeing as the amount provided decreases over time due to programmed ‘halving’ occurrences.
In this exertive process, miners guarantee the decentralization, transparency, and reliability of Bitcoin, and for that matter, they are greatly involved in its operational ability. They adjust the greatness to which the ledger can be trusted using extra mining to preserve, this ledger as it is.

Even though some people see miners as been negative to the Blockchain adoption z they still play a very important role

The role of minus is crucial in the blockchain and they are the ones who are producing blocks and validating to ensure that there is no manipulation on the chain and everything is fair and transparent for which blockchain is known for.
