Three hours and no blocks on BCH blockchain. Bonded mining? Bobtail? Bobtail From u/phillipsjk: https://www.reddit.com/user/phillipsjk Bobtail, but we probably can't do it in time for the upcoming upgrade. Bobtail: A Proof-of-Work Target that Minimizes Blockchain Mining Variance (Draft) https://arxiv.org/abs/1709.08750 Of course, the whole point of your post is that it is *not* variance. I think bobtail would still make it difficult to profit from gaming the DAA. Bonded mining From another thread at r/btc: https://www.reddit.com/r/btc/comments/dnc1g4/when_this_post_is_8_minutes_old_bch_will_have/ u/bissias: https://www.reddit.com/user/bissias It's very possible that the swing in hash rate is due to the recent shock in BTC price. I just wanted to take this opportunity to pitch some of our recent work called Bonded Mining. It's a proactive DAA that sets the difficulty based on miner commitments to future hash rate (along with some bond to ensure that they honor their commitment). As a result, simulations show that it is much better at coping with price shocks than the status quo, which is essentially a reactive feedback controller. https://people.cs.umass.edu/~gbiss/bonded_mining.pdf
