It has come to my attention maintaining the current priority algorithm is n= ot=20 even expensive, so I think I'm inclined to NACK using starting priority=20 altogether. Since I am the mining maintainer for Core, I believe it's=20 reasonable for me to decide on maintenance tradeoffs... Therefore, my goal in this matter will be to review #6357 in depth to be=20 merged, and follow up with #6898 based on the current default policies. > >> * Default block priority size will be 0 > >=20 > > We should not be influencing miner policy by changing defaults. >=20 > I agree changing policy defaults is meaningless, but in this case it > is supposed to signal deprecation of the policy option. This is a bad idea anyway, since priority is the best metric we have right = now=20 for ensuring legitimate transactions get mined despite spam attacks. Luke
