Not sure if the propagation delay is sarcastic or not (hard in writing), but network latency is worse with satellite links. Which then doesn't matter because network propagation is largely set by verification worst cases.
- mrb 9y agoI was not sarcastic. Studies like http://www.tik.ee.ethz.ch/file/49318d3f56c1d525aabf7fda78b23fc0/P2P2013_041.pdf http://www.tik.ee.ethz.ch/file/49318d3f56c1d525aabf7fda78b23... have shown that 5% of nodes with a regular internet connection still haven't received the block after 40 seconds; and the median time is around 13 seconds. The sat latency at 1-2 seconds is much lower and would hugely improve block propagation delays. Edit: a second paper (2016) has similar findings: 10% of nodes haven't received the block after 79 seconds: http://fc16.ifca.ai/bitcoin/papers/CDE+16.pdf http://fc16.ifca.ai/bitcoin/papers/CDE+16.pdf
