Second Look at Weak Blocks

[instagibbs]

@ajtowns

The downside to that approach is that given the poisson intervals you’d “often” have 50 or 100 weak blocks between each real block

I guess there is a large design space to explore here where not all weak blocks have to be fetched or sent in a given period. Nodes can decide to not fetch subsequent weak block transactions, and maybe use weakheaders first to further reduce extra bandwidth usage at the cost of a bit more latency.

@ajtowns

and you’d “often” get weak blocks being found only a few seconds after the previous weak block.

Seems fine to me, unless we commit/transmit more data than top block we probably haven’t seen a lot of these transactions in a prior weak block.
