Hi Taek,
I understand that Siacoin is on beta version where your team are working hard these days to get it into production.
I just would like to ask any approx date, we will see sia officially released. I don't mean a specific date. I rough estimate (this year, first half or second half of next year, etc)
Hard to guess. I imagine that by Jan 2016 we'll be ~stable for long term use, but still beta. Perhaps by June 2016 we'll release an actual 1.0. Depends on how many features we add before deciding that it's complete enough.
