Let’s talk about ASIC mining

No, they are not dead. Monero attempted to be ASIC resistant, forked, and for short time it was. Now there are reports that ASIC’s are back on that coin at a greater percentage than before. The difference now is that who ever has them will remain silent about it.

So making Zcash ASIC resistant, unless a complete revamp of how things are done, is pointless.


That is of course an assumption that it’s secret ASIC…it could be worse, it could be FPGA’s. Good luck bricking those off.


if asic is 50%, or 100% more efficient that GPU, it’s one situation.

other situation when asics that are 1000% more efficient are announced and dev-team of “asic-resistant” coin does absolutely nothing about it, zero reaction.

we should speak about how insane are zcash dev’s.

The mining space changes so rapidly that it’s hard to predict what the next innovation will be. There is a clear demand to make a device that is both flexible, adaptable and faster than common GPUs. Even small percentage advantages might be worth it for those entities at scale. It’s a toss up whether or not those entities will choose to sell to the public. My thought is that they won’t, finding it more profitable to keep innovations secret and competing with other well funded entities doing the exact same thing. Public mining days might be numbered, which is a sad proposition.

That said, I think it will probably take 5-10 more years for the mining industry to fully mature to a state of predictability. At that time we will be in an entirely different class of hardware focused on extremely low power usage and highly efficient cooling designs. This will most likely shift to two-phase immersion cooling with novec-like fluids (these are really cool btw). As non-mining data centers move to these more efficient technologies, to get higher density per sf, the prices will decrease dramatically for other industries like the crypto mining space. Advancements happening are both fascinating, exciting and also at times worrisome considering our goals of a fairer coin distribution alongside a highly decentralized and secure protocol.

Maybe devs should include by now a new attack vector, (mass) infected Asics …

Once @BITMAINtechcomplies with the GPL licenses for the firmware I will disclose the vulnerability to them so that they can fix it. pic.twitter.com/zwsAaPQjRL

Extremely unprofessional of James Hilliard. When I read that it instantly erased any respect for him as a security researcher. I understand his position with respect to GPL, but there is a better way to go about it in a non-public way.

Also, something is slightly off about you posting this @bitcartel. If I’m not mistaken, you are a BU member, which is pro on-chain scaling of Bitcoin. I’m not sure why you would promote James Hilliard who fought that scaling initiative before the Bitcoin split.

I posted a link to CCN.

If you take a look, TheBlockCrypto, BitcoinMagazine and CoinGeek also mention James Hilliard, because, well, he discovered the vulnerability.

It would be impossible to write a story about the issue without mentioning him!


So innosilicon now has a ASIC “GRIN”

Grin does not implement a flashy new consensus mechanism like proof of stake to achieve consensus. Instead, it goes back to the bread and butter of PoW using the Cuckoo Cycle algorithm.

Cuckoo style PoW was selected to mitigate against the Bitcoin-style “hardware arms-race” by making it ASIC resistant. Cuckoo Cycle is a memory-bound algorithm, making it viable for CPUs and increasing its decentralization.

The difficulty of mining in the network is based on the current hash power and is designed to average a fast block time of around 60 seconds. You can find extensive information on Cuckoo Cycle PoW in the white paper by John Tromp and Grin mining on the Grin Github.

It used to be considered ASIC resistant, but I’ve realized for some time now that ASICs sporting tons of SRAM have a huge efficiency advantage over GPUs. Thus, Grin’s primary PoW of cuckatoo31+ is made as ASIC friendly as a memory bound PoW can be.

Even Grin’s ASIC resistant secondary PoW, cuckaroo29, required some special measures to disincentivize lean mining, and can only maintain its resistance by frequent tweaks (Monero style).


In Central Alberta I am on a floating power rate. Generally most electricity providers here offer a floating rate that goes from $0.03 to $0.08 but averaging around 3 to 4 cents.

There is a flat rates around 5 to 7 cents per KWH but I do not know anyone who uses that and most my economic friends insist the floating rates are cheaper on average.

Can someone give some feedback how the ETH constantinople upgrade worked out for the miners, gpu and asics?


in terms of income, it barely changed for gpu’s.

asics i don’t have :slight_smile:

So maybe today we start talking about harmony mining again?! Hmmm?!
Maybe my ideas all suck but we better come up with something
Progpow is being worked on as an alternative but not by the Co, idk where they are on this now

That’s the poolin mining pool adress … near 40%.

Not sure if someone is coming up with somthing having in mind the ~1+ year preparation time for changes … :thinking:

Just came across by accident on this FPGA miner, not much more differences by now to a whole asic in my opinion:

Blackminer F1

HardFork by Monero to become more ASIC resistant ???

Hashrate 472.391 Mhash/s -46.97% in 24 hours
asic resistant , xmr team keep their promise ,they are not liar


What are you looking at? I posted a SS of their network Hashrate… The minimal drop is more than likely due to not updating to the newest version

Either two things happened, either there were no ASIC’s there or it failed
