Many people think hash functions are simple, but this is where it’s easy to get things wrong:
It’s nearly impossible to recover the original input from the hash value of a secure hash function, and it’s also very difficult to find two different inputs that produce the same hash value.
Proof of work works because hash results can’t be predicted in advance; the only way to find a hash that meets the difficulty requirement is to keep trying.
Don’t confuse a transaction hash with a private key: transaction hashes can be public, but private keys and seed phrases must never be shared with anyone.
At its core, $BTC mining involves repeatedly calculating SHA-256 hashes to find a result that meets the difficulty requirement.
Just my personal opinion—take it for what it’s worth; this isn’t advice.
