Re: == Bitcoin challenge transaction: ~100 BTC total bounty to solvers! ==UPDATED==
RTX 3060 (non Ti) = 2,400 MKey/s (2.4GKey/s)
RTX 3600 Ti = 2,800 MKey/s (2.8GKey/s)
RTX 3070 = 3,100 MKey/s (3.1GKey/s)
RTX 3090 = 5,250 MKey/s (5.2GKey/s)
RTX 4090 = 7,750 MKey/s (7.7 GKey/s) (yes, you read that right lol)

Great work
Your speed test without power limits ?
I make few fixes and now see small speed up.
now RTX 3070(pl 170w) = 3217 Mkeys/s
I calc only dp32 for #125

Re: == Bitcoin challenge transaction: ~1000 BTC total bounty to solvers! ==UPDATED==
I would like to understand how it is possible to get that quantity of keys. It is something of really amazing 
As I read, this software scan 1exakey/s with your hw?

this is not 1 ExaKey/s this like 1 Exa Compares per seconds
if you have 4 Gkey/sec generated on rtx 3090 and check via bloom filters for example 238M public keys per seconds,
you have 1 000 000 000 000 000 000 compares like 1 Exa Compares per second
1 Exa Compares per second but only for generated 4 Gkey/sec

Wait, you can use work files? People sell them for money? Lol in order of P. I have deleted near 1 GB of them because I thought they were useless, actually every time I start I delete the previous work file, I just kept a few of them.😅
workfiles contain poins and a collision can be found by comparing all previously found tame and wild points.
could you may have already found a collision several times today with the found earlier but already erased ;0

This is not JeanLucPons version of Kangaroo
this have a lot of unnecessary checks that slow down the process.
JLP uses assembly instructions to perform GPU computations, also overall process of jumping is pretty good optimized in my opinion. Can you please give an example of non-optimal computations in JLP code, by optimizing which we can get a such increase in speed?this have a lot of unnecessary checks that slow down the process.
1. separate search either looking for tame or wild
2. remove realtime collision checks
3. modify check for prefixes of founded kangaroo
4. try other cuda implementations of ecp VanitySearch, BitCrack and forks here have many ideas

I always like numbers!
First, what is this modified kangaroo program?
Verified that a 3090 gets 4.8G Key/s

The plain cuda version of secp251 and several optimize changes have this speed.
RTX 3070 with power limit 170w 2.4 GKey/s GPU Ram Usage 3.5GB
RTX 3090 with power limit 350w 4.8 GKey/s GPU Ram Usage 8.0GB
And one dedicated server for check
have 32GB RAM ( 8gb+ ram need for bloom filters )
~140Gb of nvme used for kvrocks storage for store 2^31.10 of DP32
or 35Gb if use DP34
ps4all. Possibly I'll find time for compare if you have dp's (or work file fromJeanLucPons Kangaroo ) for still determine 120 and check wild/tame and later
(in compared dp's included buyed from zielar)
But i rarely come here.

#125 need 2^63.10 ops
23330 days (559920 hours) of work one RTX 3090 (4.8 GKey/s) modified kangaroo
1 hours price is $0,117/hrs
need ~$65510 for 1 months rent 777 pcs (97 rigs of 8x3090)
~$65510 need for get $340082 (12.40 btc)

Not a 32 times bigger but √32 like ~5.65. this not full space search, this birthday collision check.
You can compare 'expected operations' for
115 2^58.1
120 2^60.61
125 2^63.10
130 2^65.61

So for interested groups/individuals - I have these progress files and I will sell them for 2ETH (upfront payment). If you are interested, please contact me via private message. To be fair - I sell files only once.
Hello!
I want to clarify, do you track PM? check it pls...
