I’m specifically asking about how consensus works, especially in terms of how Bitcoin Core software determines which blockchain is considered valid and which is orphaned.
We know that accumulated difficulty does not always correlate with the longest chain.
So, there’s no guarantee that the longest chain represents the highest amount of proof of work, correct?
Instead, it relies on the difficulty field in the block, right? Not the number of blocks but with leas difficulties.
In short, please clarify that my understanding the higher difficulty but in shorter chain is more reliable than less difficulty accumulated in longer chain.
