Hi, Ive been looking into FlyClient first described here. I don't see any BIPs, or previous discussion in this forum about it either.
On bitcoin It could allow a light-client to verify the entire work of the heaviest chain with a single ~100KB proof.
It can theoretically be done as a soft-fork by injecting a single hash into the coinbase tx (similar to how segwit is committed to).
What do you guy's think?
