the "instamine" was due to megaminers with farmloads of mining rigs hitting our system right off the get go. block times have begun to stablize, not quite to 35 second block times yet, but the dagger algo will fix that as the day goes on.
every coin has problems upon launch. we got HAMMERED and are still working things out. i ask for your patience. what happens a few hours following a launch does not make or break a coin and we have a lot of work to do from here on out having SOIL set as a currency with merchants and getting DApps developed and set.
unfortunately there was absolutely nthing anyone could do to prevent the massive hashrates a few indivuals threw at the system. there is no governor software out there to limit single IP addresses... i spent hours trying to find something, that monkey doesnt exist yet.
Best way to prevent "instamine" of many coins on launch is (or was - in SOIL's case
to implement dynamic block reward: you start small, say 0.3 XXXcoin per block, and then increase it, steady and smooth, up to target (8 per block, for soil). That process could take several hours or several days, that's up to devs and/or community. BUT - that good thought came late
but we got it now...
