Topic: Bitmain just announced the AntMiner A3 - 815GH/s Siacoin miner - Blake(2b) - page 31. (Read 12766 times)

^ Yeah I don't think Bitmain made the decision to come up with the A3 miner just to bully the SIA developer team.

If the majority of the mining community is using bitmain miners, I highly doubt they'll agree to it.  This is just a jealous dev who's GPU's will be worthless for SC now.

Yes I did. Thx.  Sort of feel sorry for all of their early investors/buyers.  Just a tad.  Obelisk had to have known that they were not working in a vacuum.  Competition is going to come.  This is an interesting development and just a prelude of what is to come,,,, because,,,,  in short time (2-3 years) EVERY major coin will have ASICs developed.  GPU mining will always be possible for multiple shitcoins, but ASICs will dominate.

The thing is, you can still go to Obelisk site and pre-order the Blake2b miners from their second batch until the end of the month.  I was considering it, but did not like the wait.  This was sort of an introduction to me showing how Bitcointalk works,,,, when this Obelisk miner came out, no one was talking about it here (trying to keep it quiet I suppose, lol).  I couldn't even find a thread about it here at Bitcointalk.  It looks like many experienced miners loaded up on the Obelisk offer and now will be left holding the bag.  I am sure the Obelisk miner will still ROI, but not nearly as fast.  My lesson is, if you are being offered a coin specific ASIC miner, then the offer is worthless unless you receive miner right away.   This 3-7month pre-order BS does not work when you have cash hungry capable competition                  

From a pure profit standpoint, you're absolutely right.

Me I support SIA first, profits from SIA second. It's for this reason and some others I'm choosing not the buy the A3 at this time.

Announcement from Sia team :

Bitmain has announced ASICs for Sia, shipping in 7 days. 1275w, 815 GH/s, ~$3200 USD. They are more expensive and less efficient than the Obelisk SC1, but they ship several months sooner (7 days as opposed to several months).

Bitmain has a long history of being abusive towards coin communities, their customers, and towards coin developers.We prepared for something like this by adding an extra feature to the SC1. We can do a soft-fork that slightly changes the PoW algorithm which would invalidate the bitmain ASICs, but allow the SC1 units to continue working. In the event of an attack from Bitmain, we can activate this soft fork. At this time, I do not think it is necessary, but if they start mining empty blocks or otherwise prove problematic for the network, we have recourse that does not involve destroying the usefulness of the SC1 units. This fork would of course require community adoption, it's not something the devs could decide to activate on their own. It would be a UASF, because the majority hashrate would not be standing behind the soft fork.

Overall, I do not think we have much to worry about. Hopefully (and very likely), this soft-fork will never be necessary. But I wanted to remind everyone (including Bitmain) that, at the end of the day, it is the community that has control, not the miners. If ASIC manufacturers act in a way that is harmful to the network, we have recourse.

With this device only the Siacoin is minable? nothing else?

Another question,
Until now how Siacoin was mined?
