Definition
A soft fork is a change to the Bitcoin protocol that makes the rules stricter. Blocks produced under the new rules are still valid under the old rules, meaning non-upgraded nodes continue to function (though they may not enforce the new rules). This backward compatibility makes soft forks less disruptive than hard forks.
Notable Bitcoin soft forks include SegWit (Segregated Witness) in 2017, which changed how transaction data is stored, and Taproot in 2021, which improved scripting capabilities and privacy.
In Simple Terms
A backward-compatible protocol upgrade. Old nodes still accept new blocks without upgrading.
Soft Fork is a term used in Bitcoin mining related to network & protocol.

Understanding soft fork is important for Bitcoin miners because it directly impacts mining operations, hardware selection, or profitability calculations. Whether you are a home miner running a Bitaxe or operating a larger ASIC setup, this concept helps inform better mining decisions.
