Bitmain just announced the AntMiner A3 - 815GH/s Siacoin miner - Blake(2b)

[btcapollo]

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.

Has batch 1 been released? Does this manufacturer have a history?

This is a very interesting plan from the Sia team. Seems like governance will be the important topic for 2018.

Just chest thumping. That would be suicide to Fork in response. They could lose most of, if not all miner support. Bitmain could just re-flash the firmware to respond? Initiating the fork could actually give control to the ASIC's miners, of the entire surviving coin. I suspect Bitmain would like this attempt. Bitmain are some cagey cats man. They know what they are doing.

[BenRickert]

I am a sia gpu miner. When will these miners arrive? I will stop mining sia because of the dif increase, but would like to know when to stop

Reported 10 "business days from today". Or two weeks from today. We'll see if they can meet the deadline. I suspect they will be close. They are on a mission. " Seek and destroy".

Guys,
What is good ASIC mining pool for A3?

[sil2222]

Guys I have 4 Bitamin coupons $125 each selling for $50 per coupon. Prefer LTc for payment. Pm me if interested.

Its especially ironic considering last year Sia was waxing poetic about how great ASICs will be for the network and how they are so much better for security than GPU mining.  I guess that only applies when they are profiting off of the ASICs?  This seems like a giant strawman argument.  What the hell do they mean by "an attack by bitmain?"  And why would the A3 mine empty blocks.  I bought an A3 but I would almost like to see them go through with this soft fork idea to watch their coin implode.  I  don't know how they would implement it seeing as the people providing 100% of the hashrate will be owners of the A3.  

Another piece of irony:  Obelisk bagholders are on here bitching about Bitmain selling 6000 of these units (which I don't think there is any way to verify this) but they seem to conveniently forget that Obelisk was trying to sell 10,000 in their pre-sale!  The actual number came in under 2000 though since most people don't want to tie up $2500 worth of bitcoin for a year.  What Obelisk should have honestly done is create a Kickstarter.  Would have went out to a larger audience and there would be less expectations.

Yeah, I feel like Obelisk would definitely be shooting themselves in the foot if they tried to pull that stunt. They can't have it both ways.

[-DarkByDesign-]

Are there going to be more sold or?

[evilfatone]

Will the introduction of all of these miners and coins dilute the market and devalue the coin?

what makes u think it will devalue the coin? look what happened with l3+ lightcoin went up x5 in value when hashrate rocketed, with d3 dash rocketed in price with hashrate increase, a good rule of thumb is cash follows hash, so i won't be buying one of these miners but i will be buying up some sia to sit on for 6 months, who knows it could do a hefty 3x - 5x once all this hash rate hits

[dndssc]

Siacoin team should be happy that bitmain make a big investment on siacoin miner, the price of siacoin will rise! I don't undestand this threats!
Sorry for the obelisk team, but I think that all obelisk miner will be sold anyway (the price is an half than bitmain a3 antminer)

the Sia miners are MADE to support the Sia network of asic's for cheap anon storage at $1 to $10 amazon cloud pricing...thus forking the coin is no big deal in that the sia tech

folk see the coin as a means to run this safe asic network for the above

thus, forking the coin (right or wrong) will be no big deal to them, IF they come thru with the real deal anon and decentralized 10c on the $1 vs Amazon cloud storage that is

uncrackable and decentralized in scope

not saying it is the correct path but yeah...they'll fork it in a heartbeat and/or just make their own coin for the purpose again....they have often warned siacoin price is

speculation and they are not interested in that part at all....

we will see

[CryptoCrane]

I really hope these are more reliable than the AntMiner D3 was.

[CryptoCrane]

Looks like they're in-stock again!

[Searing]

Looks like they're in-stock again!

IF they were ..they are gone now (not interested...but watching)

3 min from your post above ..that has to be a record IF it was not a glitch and a couple unpaid units that pop'd back up

Worried about decentralisation of SIA and other blake2b coins? We have a miner coming for blake2b: 3.5TH for 1000W with 135 chips, coming very soon. #DragonMint

This is going to be a real Shat show.

Just received the following email from Bitmain too:

We've just re-opened the same Antminer A3 batch!

To avoid hoarding by resellers and to ensure more users in different time zones can purchase an Antminer A3 unit, we will be re-opening the same batch after every hour beginning 11AM (18 Jan, GMT+8).

Thus, you may intermittently notice that the batch is out of stock. We will announce on our Facebook and Twitter accounts as soon as the batch is completely out of stock.

Regards,

The Bitmain team

It was no glitch, they were available.  They made some announcement about re-opening sales on the hour to defeat resellers from hoarding the units.

[welchy8764]

Check at top of every hour.. . Looks like right on top of hour and  only open for a few minutes..

Everyone was all worried when btc asics hit the market and look at it now.  It can only create more competition and make it stronger.  It's a compliment to SC that this is happening.
