Absolutely great idea to use bitcoin unlimited with Xtreme Thin Blocks and xpress validation to speed up delivery of blocks into and out of China.
There is a proprietary fast relay network, and this would be a second network that is open source.
You can donate to this initiative to fund this Xtreme Relay Network. I just sent a donation their way, as I believe this project does a few important things.
It gives miners a choice of relay network that is not affiliated with Core. This reduces vendor lockin.
It allows bitcoin to scale over unreliable and slow network connections. The performance will be monitored and perhaps improved upon.
Most transactions are made outside of China. Most blocks are found inside of China. That means that transactions must pass through the firewall twice, once in each direction. It really makes no sense to do this through such a "great" firewall.
