Well you aren't answering my main question which is Lightweight wallets , what is going to happen to those and why should I switch fast . I'am not using Bitcoin Core anymore anyway and the big question will I lose my BTC ? Bitcoin XT bitcoins = Bitcoin Core bitcoins or not ?
As far as I understand Bitcoin core BTC are the same as XT BTC until XT pushes its first block larger than 1MB. At that point XT BTC are different than core BTC. Whichever chain grows faster becomes the valid chain and valid BTC. Your SPV wallet compatibility depends on whether the SPV server you're using is using XT or core.
Don't spend your BTC on the XT chain. If your SatoshiCoins are tainted with Gavincoins and you try to spend them, catastrophic consensus failure may occur, and you will lose them.
http://qntra.net/2015/01/the-hard-fork-missile-crisis/That's old and outdated stuff, before Bitcoin-XT came out with its consensus protocol built in. This fork will occur only when over 75% of the network is already running a Bitcoin-XT node for more than 2 weeks, so by then there's already a big majority force behind the fork. The actual percentage at the time of the fork will probably be closer to 90% or more at this point since the undecided or unwilling minority will be heavily incentivized to switch over as well and go with the rest. Before this fork even actually happens everyone is already prepared for it, except a few die hard 1MB block lovers and some BTC haters who just want to stir the pot. Their fate at this point will have already been sealed though, and they know it so they are making a lot of noise now. So the above is basically just an attempt to scare people into not running a node like Bitcoin-XT so they won't ever reach the needed 75% for a fork in the first place. I've been sitting on the fence in this whole discussion until now, but I have to admit I'm now really considering running a Bitcoin-XT node myself and cast my own vote this way. I was already convinced we need bigger blocks, I've just been waiting for the whole discussion to flesh out a bit more in case I had overseen certain things.
You and me both. The more hyperbole I saw from the 1MB block crowd, the easier the decision got.
Peter R's paper for me eliminates any reasonable doubt that remained.
For sure there are a lot of hypothetical edge case scenarios, but there always have been. No point icing the cake if its already gone bad.
I'm switching to XT today ready for the next release.
