Six months ago, efficient block relay to nodes was only an idea.

Thanks to the tremendous efforts by Peter Tschipper, @sickpig and Andrew Stone, efficient block relay is now a reality. Developers from all implementations including Classic, Core and XT not only agree that it was a great idea, they also want to implement it (or something very similar to it) in their implementations too.

Visualizing the improvement in propagation times

We conclude with an animated race between a Xthin block and a standard block to the other side of the GFC. The animation is representative of real performance and plays at the real speed.
