[NEW] Bitmain Announces Antminer A3

[dutchlincoln]

Just heard the news that the Sia Devs are going to do a Soft Fork to make sure that only the ASICs made by Obelisk can mine on the Sia blockchain, for a period of time.

Which means all other ASIC miners, including the A3, would not work once that happens.
Although I guess most people have their A3s shutdown, other miners, for example, the Innosillicon S11 which has a hash rate of 4.23T, is still able to generate a good amount of SC each day.
I have not gotten my ROI for my A3s and S11, felt sad about it.
But what can I do about it? Learn a lesson and move on.

i just demolished it by ripping a fan off in favor of one of my S9's...
A3 was a big mistake to buy, just like all other altcoin miners from Bitmain.

Totally agree, it was a big mistake.
People who bought D3, A3, B3 from Bitmain should be regret doing that.
In my case, no more ASICs, never ever.
I would rather use the fund buy Bitcoin and Hodl.
Now the issue is what to do with these soon-to-be doorsteps (A3 and S11).
I wish some recycling company can buy those ASICs back - the aluminum cases, fans, control boards should still be re-useable.

Is there anything to do with  Antminer A3 if you dont have free electricity


i have few antminers standing in my home and want to know if i could mine other coins or smth


or if is there any chance in future to use them because im about 30% ROI from them

pretty breaking news if you somehow have not heard and have any antminer a3 that you still even keep plugged in . .

David Vorick of Siacoin has announced the team has decided to "brick" the Bitmain Antminer A3s and Innosilicon S11 Blake2b Siacoin ASIC miners to allow their Obelisk Tech SC1 miners to be the only miners on their network. Official Post - http://bit.ly/2DWR2Ri

Hey guys,

Is there still any possibility to mine something? (not talking about elec issues)

I mean... SC time is over and nicehash is not acceptiong blake2b/sia.
I am really not talking about profitability now, I am just asking if there is still any possibility to use the miner for mining.

Any suggestions?

Cheers

The only thing that sia did, is fuckup a lot of miners that supported their network. Bitmain has their pennies safe, the miners lose. But: i speak for myself; i will not ever ever buy or support a miner for the sia network ever. If it was my call, sia may poof down to $ zero and disappear.

Hi same situation here, I have 2 Antminer A3 colleting dust since 3 months ago.

Does anyone undestand how without changing the Obelisk machines, the pools ban the Bitmain and Innosilicon miners?

Is is really and mining algorithm algorithm change?

How different are blake2b vs blake2b-sia ?

I have been reading about the Obelisk SC1 ´knife´feature, that apparently switches the asics to an alternative mining algorithm, but it does need of a new software update... suspicious... You can read more here: https://siasetup.info/learn/obelisk

Are the Obelisk chips reprogramable like some kind of FPGA? If they aren´t the change should be small...  

How the Obelisk started to mine Blake2b-sia on the 1st November 2018? Did the Obelisk team deployed a software upgrade silently?

Look at the profitability on Obelisk SC1 on the 1st Nov 2018, it spiked to 100$/day. https://www.asicminervalue.com/miners/obelisk/sc1

In case of Obelisk has ASIC chips inside, the hashing core chip did not change, an the ´knife´at the end is only a software wrapper change on the controlling board, that could be ported to Bitmain controller boards also... I´m thingking as a simple of an ID or serial number check, or changeing the number of blake2b rounds before the result is sent to the pool.

Does anyone here has an Obelisk SC1 miner? Did you notice any hashrate change after 1st Nov 2018?


Other option is to mine other Blake2b based coins like:
 - SiaClassic https://classic.siamining.com/
 - SiaPrime (SCP) https://prime.siamining.com/
 - Hyperspace (XSC) https://hyperspace.siamining.com/
 - BitcoinX (BCX)

okay  i am Sia Classic minen

which wall should I take?
the original is not working anymore!
on the original I still have one above, which broker can I trade the ....?
THANK YOU

The chips in the Obelisk were designed with a backup algorithm from day one, the changes are not simply in software. Since the Obelisk shipped after nearly all other ASICs, it is extremely unlikely any other vendor has support for the algorithm changes.
