What is a Bitcoin private hard fork?
Could you please elaborate on the concept of a Bitcoin private hard fork? I'm interested in understanding how it differs from a public hard fork and what specific changes or implications it might have for the Bitcoin network. Is it a decision made by a select group within the Bitcoin community? Does it require consensus from the broader community? And how does it potentially impact the value, security, or functionality of Bitcoin? I'm looking for a concise yet thorough explanation to gain a better grasp of this complex topic.
