I tried on some low keys puzzles with /Etayson/BSGS-cuda and my RTX 4080 is slower at sequential search than a single EPYC with 64 cores and bloom filter of about 1T in size.
Indeed, RCKangaroo or any other Kangaroos out there are faster but on puzzles beyond 135 things get complicated.

I will try with -n 0x4000000000000 -k 8192, but for every different command I need to wait a couple of hours for the bloom filter to fill the RAM.
I tried also with all the 1.5T RAM but the speed is considerably slower because on a dual socket system, each CPU typically has its own memory controller and dedicated memory channels. This architecture is known as NUMA. Latency increases and bandwidth decreases when a CPU accesses the memory attached to the other CPU.
So I'm running 2 separate keyhunt apps with these commands : numactl --cpunodebind=0 --membind=0 ./keyhunt0 -m bsgs -f 135.txt etc etc (1T RAM)
and numactl --cpunodebind=1 --membind=1 ./keyhunt1 -m bsgs -f 135 etc... (512GB RAM).
You are right, 135  is very hard but better to try my luck on random than going sequentially specially on these high ranges puzzles.

Yes, checking keys through a bloom filter which is loaded into RAM of about 1T in size. 

Are you using BSGS random to break a 256-bit Bitcoin address where the length of a private key is 64 characters long?   That's wasted energy and resources. Even puzzle 135 is almost impossible to crack by using BSGS random where the prv key is having only 34 chars in length.  
Good luck though, I'm currently scanning puzzle 135,  bsgs random with 260 exakeys/s and almost giving up.

The 'Stats output every 1 seconds' give you wrong speed, to know the actual speed set the output to at least 10 seconds ( -s 10)

Nope, the speed is correct, changing to -s 10 or even -q doesn't influence the speed too much .

Totally agree, #135 using BSGS will take million years to crack. I went further and changes JLP vanitysearch, that it will calculate 2^30 precomputed table and run that in each thread against public key using bloomfilter, using symmetry and 8x 4090 can do 48 billion of 2^31 ranges per seacond, and that will take millions of years to go through 135 bits. I think BSGS at this stage is useless.

So if your 8x 4090 can do 48 billion of 2^31 ranges per second (equal with 103,079,215,104,000,000,000 keys per second) it means your hardware is X2 slower than an AMD EPYC 64 cores + 1T RAM , running on BSGS random, doing 260,949,667,359,921,111,308 keys per second. Indeed, random is random, can never hit the private key especially on bigger ranges, while sequential search is a guarantee.

Nope, the speed is correct, changing to -s 10 or even -q doesn't influence the speed too much .

This is my hardware https://ibb.co/27kkq4yT
2 x AMD EPYC  64 cores each
1.5 T RAM
-n 0x1000000000000 -k 16384

I am also running 135 puzzles, and using bsgs to run some old lost mining addresses. I have been running for more than half a year in total, but I haven't earned a penny. Haha, I wish you good luck.

Ok now I understand, thank you very much sir, I'm using your Keyhunt in BSGS random at the moment only 64Gb RAM but I ordered another 64GB with a 7950x Great program btw

Sorry for asking but I don't understand, let's say for puzzle 135... if I add/substract with the command ./keysubtracter -p 02145d2611c823a396ef6712ce0f712f09b9b4f3135e3e0aa3230fb9b6d08d1e16 -n 100 -b 90 ...   then on Kangaroo what range should I use ? The range for 135 bits key or the range for 90 bits ?

IMO the Creator is using you and your brute-forcing software available on Github to help him recover a big wallet which maybe was lost in the past, it could be even a 160 bits key with a known pubkey. (eg this one https://bitinfocharts.com/bitcoin/address/12ib7dApVFvg82TXKycWBNpN8kFyiAN1dr )
He can't do it alone so sacrificed some of his bag by creating this puzzle.

The first coin which will have a real utility is XRP.

All in XRP.

In afara de bitcoin care toata lumea are sau si-ar dori sa aiba cat mai multi, in acest post fiecare isi enumereaza monedele pe care le detine. Deci titlul postului ar trebui schimbat in "Ce monede detineti ?"

O fi vreun nou "smen" si cu Revolut.

Am cont la Transilvania si de cateva luni nu mai pot cumpara cripto-monde cu cardul. Si nici sa retrag pentru ca am incercat sa retrag de la Bitstamp si s-au intors banii inapoi.
Se poate totusi cumpara prin Revolut, numai ca acolo nu detii monedele propriu-zis si nu le poti transfera intr-un wallet personal. La fel se mai poate cumpara si de la Coinmama dar cred ca o sa inchida si acolo accesul.

M-au sunat si pe mine de cateva ori, dupa ce le-am zis ca detine cateva cripto-monede si au vazut ca sunt in domeniu si stiu cate ceva mi-au inchis telefonul fara sa zica nici macar la revedere.

Do you mean developer ?

What devs ?

2nd. Electroneum was first.

I`m mining ETH with 7 x 1080ti with a hashrate of 276.4Mh/s.
It was to be profitable a few months back when difficulty was low but now I`m making about $11/day with a power consumption of $6/day . So if you have just a few cards is not so profitable.
