From 9055c16efad80d0c69992e7992083f967733aa9c Mon Sep 17 00:00:00 2001 From: Jeffrey Wilcke Date: Thu, 31 Mar 2016 17:43:41 +0200 Subject: accounts/a/b/backends, core: chain maker homestead block set to 0 The chain maker and the simulated backend now run with a homestead phase beginning at block 0 (i.e. there's no frontier).
