I’m presently studying about SegWit and making an attempt to know what it’s used for. It’s clear to me that it was primarily launched to beat txid malleability, however…
Taking a look at this query and the reply seems like Bitcoin, by updating the best way that Bitcoin script works, disabled the txid malleability even with out SegWit. So you’ll be able to now not add extra content material to the script, preserve it legitimate and have a special ID. So, txid malleability is just not anymore potential, not simply via utilizing SegWit, but in addition by utilizing legacy transactions (P2PKH) and the unlocking script discipline. Within the first reply to the referenced query, Antoine Poinsot additionally talks about third-party malleability, however as he stated, SegWit is just not the answer for that, so it might’t be the aim of why SegWit is used in the present day.
So if overcoming txid malleability, as the primary cause why SegWit was launched, is now not the primary benefit of SegWit (because it may also be overcome with out SegWit), what’s?
One benefit/objective, I might say, might be that there’s a sign of the model of the script getting used, in order that the script language will be prolonged very simply.
What are the opposite benefits/functions of SegWit in the present day (not simply in the present day, however basically)?
