Title: Timed Retarget Post by: Gamesfreak13563 on May 11, 2013, 05:25:13 AM Why don't Altcoins have a timer that ticks down? If blocks aren't solved after 150-200% target time, it immediately lowers difficulty some arbitrary percentage.
It seems like a major weakness. Imagine a power grid failure and most miners in North America can't mine. Will the rest of the world have to just sit there while they cant have their speedy transactions?

I think it should be more gradual, not an immediate drop to one. Title: Re: Timed Retarget Post by: mr_right on May 11, 2013, 05:28:57 AM 20 min

I'd be more worried about the nukes/*insert any apocalypse here* used to knock out that many power grids across NA Title: Re: Timed Retarget Post by: DeathAndTaxes on May 11, 2013, 05:39:16 AM Who's time? Time in a decentralized network isn't deterministic.
Say x minutes pass so some nodes lower difficulty and one finds a block however due to differences in clocks some nodes believe it has been < x minutes. HARD FORK TIME. Some nodes believe the lower difficulty block is valid and some believe it isn't. There is no resolution possible.

I think there is a 1440 minute time acceptance window.Say x minutes pass so some nodes lower difficulty and one finds a block however due to differences in clocks some nodes believe it has been < x minutes. HARD FORK TIME. Some nodes believe the lower difficulty block is valid and some believe it isn't. There is no resolution possible.
