00:24 < funnyduckey> hey all; I've a question related to Bitcoin-NG, I've just skimmed through its paper and some of the other papers that tackle its security
00:25 < funnyduckey> surprisingly, I seem unable to find a clear answer to a very basic question; which is - what constitutes the actual crypto-puzzle in Bitcoin-NG
00:26 < funnyduckey> I have two ideas: 1) miners mine only on key blocks 2) miners ale allowed to mine on the very 'regular' blocks
00:29 < funnyduckey> if it was required to mine on the key-block only, then the crypto-puzzle would be the same throughout the leader's epoch; and a new leader would just sign  the consecutive regular block confirming the history of events
00:31 < funnyduckey> but then I found this paper "Game-Theoretical Analysis of Mining Strategy for
00:31 < funnyduckey> Bitcoin-NG Blockchain Protocol" https://arxiv.org/pdf/1911.00900.pdf
00:34 < funnyduckey> which seems to argue that miners can  mine on 'regular' blocks,but then there' s a new crypto-puzzle every 10 sec
00:36 < funnyduckey> then they build an entire 'advanced attack' based on this assumption; why not just mine on the key-blocks; make the miners occupied with a single puzzle and sign the latest regular block (by new leader)

04:11 < waxwing> it doesn't seem remotely off topic (I think?). You were right first time, it's usually just a quiet channel. Real time conversation is rare.

04:47 < tromp_> the actual crypto puzzle in Bitcoin-NG can be any PoW you like. Aeternity for example chose Cuckoo Cycle as PoW
04:48 < tromp_> micro blocks have no PoW
