Once a node connects to the bitcoin network, there are several tasks that a bitcoin miner performs: 1.
Synching up with the network: Once a new node joins the bitcoin network, it downloads the blockchain by requesting historical blocks from other nodes.
A Complete Guide to Understanding This Blockchain Concept
This is mentioned here in the context of the bitcoin miner; however, this not necessarily a task only for a miner.
Transaction validation: Transactions broadcasted on the network are validated by full nodes by verifying and validating signatures and outputs.
Block validation: Miners and full nodes can start validating blocks received by them by evaluating them against certain rules.
This includes the verification of each transaction in the block along with verification of the nonce value.
Create a new block: Miners propose a new block by combining transactions broadcasted on the network after validating them.
Perform Proof of Work: This task is the core of the mining process and this is where miners find a valid block by solving a computational puzzle.
Why This Matters for Blockchain Technology
The block header contains a 32-bit nonce field and miners are required to repeatedly vary the nonce until the resultant hash is less than a predetermined target.
Fetch reward: Once a node solves the hash puzzle (PoW), it immediately broadcasts the results, and other nodes verify it and accept the block.
There is a slight chance that the newly minted block will not be accepted by other miners on the network due to a clash with another block found at roughly the same time, but once accepted, the miner is rewarded with 12.5 bitcoins and any associated transaction fees.

Conclusion
Tasks of the miners represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
