Bitcoin Mining Explained TG@yuantou2048

Bitcoin mining is a process that involves adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

Mining is a record-keeping service done through the use of computer processing power. Miners keep the blockchain consistent, complete, and unalterable by repeatedly grouping newly broadcast transactions into a block, which is then broadcast to the network and verified by recipient nodes. Each block contains a SHA-256 cryptographic hash of the previous block, thus linking it to the previous block and giving the blockchain its name.

To be accepted by the rest of the network, a new block must contain a so-called proof-of-work (PoW). The PoW requires miners to find a number called a "nonce," such that when the block content is hashed along with the nonce, the result is numerically smaller than the network's difficulty target. This proof is easy for any node in the network to verify, but extremely time-consuming to generate, as for a secure cryptographic hash, miners must try many different nonce values (usually the sequence of tested values is 0, 1, 2, 3, ...) before meeting the difficulty target.

As more and more miners join the network, the difficulty of finding a valid block increases. This ensures that the rate at which new bitcoins are mined remains steady. In fact, the difficulty adjusts every 2016 blocks, or roughly every 2 weeks, based on the rate at which blocks are being added to the blockchain.

The question now arises: With the increasing complexity and energy consumption, is bitcoin mining still a viable option for individuals? What strategies can miners adopt to stay profitable in this ever-evolving landscape? Share your thoughts in the comments below!
