On improving IBD time.
Discussion
It is very cool, and kind of unites a bunch of ideas that have been floating around for some time. The key insight he had was that you can take the cut through achieved by the utxo cache and apply it on a network wide level. I'm also very much in favour of using our undo data more, and relaying spent UTXOs together with their respective spending boock.
The wizard 😃
idk, but libbitcoin makes a fully validating IBD in 37 minutes, so these kind of hacks aren't that impressive in comparison...
