does Core have or plan to have this?
I'd like to see evidence of these features working first. As far as Traffic-shaping is concerned, this is implemented in Core (Reduce upload traffic - in changelog) under another name (they claim that they "coded it").
Traffic shaping was first implemented by XT not Core. Furthermore the traffic shaping feature in Core just cuts off upload at N bytes for those who have metered plans. This is no where near as useful as proper throttling controls which Bitcoin Unlimited has even implemented within a new GUI.
This does not even surprise me. I'd like to see real data on Thinblocks, however I do remember maxwell saying somewhere that it is noticeably worse than the relay network from Corralo. So let's see.
I do no understand how this could be worse then the relay network, since Xthin is a decentralized solution. Furthermore it speeds up block propagation by a factor of at least fifteen. Block propagation times being the main restricting factor for an increased blocksize by small block proponents, you should be able to see how this is a huge breakthrough.
Tensions between Team Unlimited and Classic's Censorship Martyr Brigade are running high.
Try posting something positive on r/btc and you will get downvoted to oblivion (ergo another type of censorship, yet nobody bats an eye).
It is very revealing that you can not tell the difference between downvoting and real censorship, which has recently gone into full overdrive. Even censoring any mention of Xthin in the r/Bitcoin reddit.
Bitcoin Unlimited has all of the features that the latest Core release has. Except for RBF which the Bitcoin Unlimited community voted not to include in the latest release. Bitcoin Unlimited now has more beneficial features compared to Core. While Core is focusing on building off chain solutions, Bitcoin Unlimited and Bitcoin Classic are focusing on scaling the Bitcoin blockchain directly.
Bitcoin Unlimited and Bitcoin Classic are friends, our implementations are compatible with each other unlike Core. An example of how competing implementations can cooperate.
