"Before being added to Bitcoin Core, it will be tested very thoroughly over several days or even weeks to make sure that it is all ready."
Is that really enough?
It is also being tested right now and has been tested for the past couple of months since the first segnet went up.
With the amount of testing going on, it is enough.
4 years of thousands of people using bitcoin and they still found a bug in 2013.
and 2014
and 2015
so ahandful of people now and again doing transactions in their spare time.. well it really doesnt compare.
by the way reading the irc logs, you cannot really see much chatter about then trying to break it using scenarios it seems more like making sure coins arnt accidentally lost rather then purposefully trying to gain/move/create/destroy coins.
try not to have blind faith in a system thats not even released.
after all everything thinks windows works but i bet everyone knows what a blue screen of death is
there are atleast 12 different implementations of bitcoin all wrote with different languages and multiple version.. im damn sure they are not going to test all of them to live up to the promise of bug free backward compatibility that cannot be hacked or abused.
Segwit is conceptually sound. When it comes to implementation, there can be bugs, and that is what the testing is for, finding the implementation bugs and making sure that it is implemented to spec in their software. It is up to the developers of the other software to follow the publicly available specs to properly implement segwit.
Also the segwit irc is #segwit-dev and that is where segwit discussion happens, not #bitcoin-dev or #bitcoin-core-dev
