There is specialized hardware for CN/R, I'm sure now

Sumokoin nonce distribution chart: i.imgur.com/C9eFmD6.png

They stayed on CN/R, red line marks when Monero forked to RandomX

hm? the nonce distribution looks more uniform after the fork

well - one obvious division in the nonces, but the two halves have no obvious streaks

what happened between blocks 270000 and 280000?

it's not any of existing GPU miner software for sure

270-280k - it forked to CN/R

neither any proxies produce such nonce pattern, so remnant botnets mining through proxies are also out of the equation

so you're suggesting that CNR ASICs left Monero and jumped onto Sumo after the randomX hardfork?

yes

probably FPGAs

Vega GPU spends 2 times more on power than it earns from mining

got a hashrate chart for them around that time?

hmm

I can add it to the picture

I have full "get_block_headers_range" json RPC output from sumo daemon

that 2:1 cost is pretty nasty. So are Sumo miners complaining?

moneromooo: so scratch my suggestion to use CN/R for wallet KDF

with difficulty chart added: i.imgur.com/mtSBS1p.png

any explanation of the pattern between 275000 and 355000?

this is normal CN/R pattern

GPU miners split nonces that way

depending on the amount of GPUs in a rig

hence horizontal lines

I'm guessing nothing was visible in the Monero nonce distribution?

it looks like the FPGAs are only ~30 MH/s in total

just looked at top 2 sumo pools. Each of them has ~10 MH/s miner

so 2 individual miners account for 70% of Sumo hashrate

Monero nonce distribution looked fine, at least on this scale of FPGA mining

too subtle to notice

maybe it's even a single miner who spread hashrate between 2 pools

why did difficulty drop so sharply at CN/R introduction? were CN ASIC miners on there before too?

they were on cn/heavy before

so I guess cn/heavy also had some specialized hardware

ah

so many CN tweaks have been made - and all of them ASIC'd

that's what you get with static algorithms ...

personally I'd prefer to see more uniform nonce distribution, and less of these streaks

what's xmrig's nonce pattern look like? also streaky?

This is Monero's nonces: i.imgur.com/qiZoooA.png

last 2 forks are shown

RandomX pattern is dominated by proxies

so 256 horizontal lines

and a bit thicker line at the bottom - individual workers

so it sounds to me like ASICs are doing the right thing - starting at randomly selected nonces

and GPU miners are being too regimented

I wonder if that means they're using a true hardware RNG

"they" = asics in that last sentence, hyc ?

another Grin ASIC cancelled

Inge-: yes

tevador what do they mean "GPU ASIC" ?

so basically they're saying their chosen foundry partner was incompetent?

TSMC I presume

or their design was too exotic for the foundry

I guess they call it a GPU ASIC since Grin is mined by GPUs

otherwise it has nothing to do with GPUs

you would think the foundry guys would assess up front whether they can handle the design or not

in any case, RandomX ASIC looks even less likely to be designed

it amazes me after all these years of bitcoin asics screwing over people, that there were enough suckers to buy into another asic preorder

well, they're all getting full refunds, so I wouldn't call 'em suckers unless they don't get their money back

I wonder who the actual foundry is, since TSMC clearly have no problem producing GPUs and CPUs, high complexity stuff

I thought that mining ASIC is even easier to design than CPU/GPU.

ravencoin are realizing that tweaks don't work: reddit.com/r/Ravencoin/comments/epk…e_we_hit_a_peak_in_difficulty_again

sech1, can you share code that transform nonce.txt into image?

I can promise that will not use it for profit.

and the code that creates txt files from RPC json data: paste.debian.net/1126528

first one is for gnuplot

sweet, that's what I came to ask for!

cohcho: pool PR is great

thanks

total miners 28564

I've just got what they change in xmrig

(they == botnets)

b'donate.v2.xmrig.com' replaced with b'127.0.0.1\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'
