Apart of being this one engine scam or not, there are some new mining equipment on the XMR network obviously:

https://miningpoolstats.stream/monero

They removed auto-calculator to avoid panic, but now Total Network Hashrate = 712 MH/s, Known Pools' Hashrate = 328 MH/s,
so UNKNOWN Hashrate = 384 MH/s = 54% of Total Network Hashrate.

Remember, miner equipment manufacturer NEVER starts to sell miners to public UNTIL they'll become UNPROFITABLE to mine by themselves. So when they start to sell them, you do always lose if buy.

I think their equipment is indeed FPGA-like.

---

I propose new idea to XMR mining algo: to emulate floating point computations of higher precision that is not common in any hardware. We should imagine how to involve a true random NOISE into computations. The way we involve NOISE should meet some requirements, for example, if one doesn't add NOISE, their results should be worse in metrics of hash mined. So FPGA manufacturer must add NOISE in EACH node of its FPGA logic. If so, FPGA will be as effective as GPU, CPU, etc...

I may mistake... above are just free imagines...

I'm just a small GPU XMR miner since several month, and the last time I saw such a strong rise in hashrate was when bitmain mined  in secret with theirs asics only known by them.

It seems that they are re-offending.

In less than 48 hours 60% of the hashrate is unknown ! Houston, we have a problem  Shocked Sad Undecided
The hashrate has more than doubled in less than two weeks!

Something is happening. Either a 51% attack occurs, or specific asics are minning on the network recently.

Is it that the most seasoned supervisors of the monero blockchain can confirm or deny what appears to be an attack ?

Sorry for my English translated with google translate.

Yes this is an attack. It is not so important whether this attack has 51% nature or not. This is a new era of hybrid ASIC/FPGA attack:

or

TODAY:
https://miningpoolstats.stream/monero

804 MH/s Total, 340 Known, 464 UNKNOWN.

Hueristic, dEBRUYNE could you deliver this problem to Fluffypony and Monero Core Devs?

Since this attack started in earlier January, NO ONE MONERO CORE DEVS EVER COMMENT THIS. WTF?!

LOL, what do you want, a pre-announcement of centralized checkpoints like Dash's ChainLocks (which won't even go live for another 9-12 months)? Grin

XMR devs have been working on a long-term solution called RandomX, a new PoW that is polymorphic and uses the blockchain for entropy.

Please don't expect Fluffy to set his hair on fire and run around screaming, TYPING IN ALL CAPS LIKE A DRAMA QUEEN, just because the "XTend Hyperminer AMAP is a radically new, programmable digital mining fabric that can mine any coin, or even multiple combinations of coins simultaneously."

Even if Xtend can chew through RandomX like a boss, I'm working something that will break its teeth. Wink

This is just how the dynamic equilibrium of Nakamoto Consensus evolves.  Please don't keep screaming and crying just because we're in one of the periodic recurring 'creative destruction' cycles.  The more non-trivial adversaries attack Monero, the more antifragility accrues and the better our long-term chances of resisting extinction pressure.

Why estimate it when you can go try it out for yourself? Cheesy

This random 1-in-2-out transaction has a size of 1.9 kB and a fee of 40 microneroj (about $0.002)

Do those Chinese farms have any motivation to do a real 51% attack?  I mean double-spends, that sort of thing.  As opposed to making money mining a buttload of xmr, which is fair play.

I don't understand why MONERO simply switches to PROG PoW.  It puts GPU's, FPGA's and ASIC's all pretty much on an even keel.  FPGA's and ASIC's would only be able to achieve a 1.1 to 1.0 or 1.2 to 1.0 advantage with hash rate/power efficiency.

I've read about RandomX a lot.
https://github.com/tevador/RandomX

This mining algorithm looks very promising in order to fight against ASICs and FPGA. But it effectively denies mining on GPU too. So all our honest GPU miners will be abandoned by the XMR community if we accept RandomX algo "as-is" on github.

But indeed, RandomX looks very intriguing. It adds some random info into mining scratch pad to be collected from the blockchain. If I've understand correctly, it is exactly the idea I wrote few days before here...

In order to adopt RandomX to Monero mining,
Can we shrink down a standard RandomX data scratch pad from 4Gb to ~256Mb? So, in the client profile, when  RandomX data scratch is generated on the fly, part-by-part, only 4Mb parts instead of 64Mb should be generated?

I suppose GPU miners could adopt JIT-compiler version of RandomX to GPU mining. Furthermore newbies can play games and mine simultaneously, so this step decreases the threshold for GPU newbies to enter the Monero world, but still VERY resistant to ASICs and FPGA...

Hmm. Can we deny reorgs bigger than 10 blocks unconditionally? Mining is a random process, so it has its distribution in terms of math statistics with mean value for how many blocks need the reorg, and a standard deviation.

Standard deviation can be accumulated and counted by each node, so they can simply rejects each single reorg beyond the 3-sigma rule.

I think, manual API to check blocks beyond 3-sigma threshold proposed is a technical complication and philosophical violation.

Guys, what are your thoughts XMR compared to MimbleWimble coins or Nix Platform in term of algo and tech? Nix looks really interesting trying to solve privacy for all coins. MimbleWimble is kind of a hype atm. Do you think monero can sustain it's position in the coming privacy coins environment?

I was wondering why iCEBREAKER was trolling again in our Dash ANN thread, i guess this explains it :

Another Hard Fork Coming for Monero [XMR]? Analysis says ASIC Dominates Monero Hashrate
https://coingape.com/asic-dominates-monero-hashrate/

Quote
the current network hashrate likely consists of 85.2% ASICs (5400 ASIC machines) and some die-hard GPU miners and botnets.

Icey : next time you feel the need to unload your anxiety and worries, pls grab a stress ball.

To the Monero community : Good luck, personally i'm all for ASIC miners as they strenghten networks against 51% attacks (when they are spread over multiple pools)

If i could have a Dash for every time someone tries to connect Dash to a premine i would have a few more masternodes.. sighh.
You do know that premine means mining before public launch ? right ?
And you do know that was not the case with Dash ? right ?

Anyways, let me not distract you from your bigger problem : how to deal with ASIC miners that have completely and utterly taken over your network (85.2%).
A network that is suppose to be ASIC free....

This post should be about Monero, not Dash, and @qwizzie you're right, it was not premined, it was instamined BIG. There was some discussion what to do with these instamined coins, but Dash dev (Darkcoin at the time) did nothing to solve the issue.

In Monero we're trying not to get centralized mining farms, in order that everyone could mine it, not only the ones with cash to buy some ASIC
