However, different rules are activated at different time to enhance safety and reduce disruption. The advantage is people are required to upgrade once, not twice. Any clients designed for stage 2 should also be ready for stage 3. -----Original Message----- From: Matt Corallo [mailto:lf-lists@mattcorallo.com] Sent: Wednesday, 10 February, 2016 06:15 To: jl2012@xbt.hk; bitcoin-dev@lists.linuxfoundation.org Subject: Re: [bitcoin-dev] A roadmap to a better header format and bigger block size As for your stages idea, I generally like the idea (and mentioned it may be a good idea in my proposal), but am worried about scheduling two hard-forks at once....Lets do our first hard-fork first with the things we think we will need anytime in the visible future that we have reasonable designs for now, and talk about a second one after we've seen what did/didnt blow up with the first one. Anyway, this generally seems reasonable - it looks like most of this matches up with what I said more specifically in my mail yesterday, with the addition of timewarp fixes, which we should probably add, and Luke's header changes, which I need to spend some more time thinking about.
