You and I think very much alike. Lauda, can you point us at a really big but totally legit/non-abusive transaction?
I don't think that there are many transactions that are so large in nature (both 'abusive' and non). This is the one that I'm aware of. However, you'd also have to define what you mean by "big". Do you mean something quite unusually big (e.g. 100kB) or something that fills up the entire block? I'd have to a lot more analysis to try and find one (depending on the type).
Segwit isn't a solution designed to fix the block size limit. Its a solution to another problem that right now is undefined, that is being sold as a solution to a problem that is being actively curated by those who refuse to remove a prior temporary hack.
TX malleability (e.g.) is 'undefined'? Segwit provides additional transaction capacity while carrying other benefits. How exactly is this bad?
What problem is it that requires signatures to be segregated into another data structure and not counted towards the fees. Nobody can give a straight answer to that very simple question. Why is witness data priced differently?
The question would have to be correct for one to be able to answer it. In this case, I have no idea what you are trying to ask.
Fixing TX Malleability is beneficial to everyone.
This *other benefits* - they include giving the ability to introduce consensus changes without hard forking. This is because we are told that a contentious hard fork is a terrible thing. How does anyone know this for sure!?
A hard fork is good. (Note the absence of the word contentious). A hard fork establishes Nakamoto consensus, and is the only consensus vital to the ongoing successful operation of the bitcoin network. The incentives that drive this consensus mechanism are sound. The fear from those that do not see this is overwhelming. To subvert this is to destroy fundamental parts of bitcoins architecture.
I thought you would understand what I meant when I asked the question, sorry if I have used the wrong terminology or something. I can make it a broader question, then perhaps we can investigate the specifics.
Why does segregated witness change the tx fee calculation?
