Subject: Re: [bitcoin-dev] BIP - Block size doubles at each reward halving with max block size of 32M
Date: Fri, 13 Nov 2015 10:56:55 +0800	[thread overview]
Message-ID: <CAFzgq-xmXcEKN0_0e8de0UDOJEXuivbz986-dsSC5BCYLA2t1A@mail.gmail.com> (raw)
In-Reply-To: <CAEkt4Xu6vBFtRVEnXCWJa0f9OYi9wLKwToxc3p+KPfMuV5y0GA@mail.gmail.com>

How about these specs:
* 1 MB, height < 210000;
* 2 MB, 210000 <= height < 420000;
* 4 MB, 420000 <= height < 630000;
* 8 MB, 630000 <= height < 840000;
* 16 MB, 840000 <= height < 1050000;
* 32 MB, height >= 1050000.
