So i bump into Bitcoin Collider https://www.reddit.com/r/Bitcoin/comments/655j0r/large_bitcoin_collider_tried_over_3000_trillion/ on reddit & discover its members consider using FPGA for better performance, this is the first time i heard of this device. If we run their program or vanitygen on it, how many keys/s can it archived?

Some examples of FPGAs are FPGA mining cards which is mainly used for mining and as far as I know LBC was optimized (if not the old versions, the latest) to use it efficiently.
On the other hand, Vanitygen is optimized for Processors while Oclvanitygen is optimized for GPUs, I don't know if it will run with FPGA either.

So the answer would be obvious.
But there are forks that have different tweaks supporting different type of devices (even FPGAs)

Does anybody know how to modify this?
I found a post on bitcoin stackexchange show how to create a bitcoin address from given hex private key

In vanitygen.c

Replace

Code:

EC_KEY_generate_key(pkey);

with

Code:

BIGNUM *res;
   BN_init(&start);
   res = &start;
   BN_hex2bn(&res, "3B1BCC5A67F38853810972B1DA8A67148FAD78C6CD6F22B2C823D141BE59C81C"); //Set up hex private key
   vg_set_privkey(res, pkey);

& remove case

Code:

if (++npoints >= rekey_at)

I intend to replace the input hex private key with function like hashcat to recover lost pivate key like this

Code:

"?1?1?1?1?1?1?1"+"A67F38853810972B1DA8A67148FAD78C6CD6F22B2C823D141BE59C81C"

When i test it on a single hex private key,by default the function keep multiply the key for new address instead of keep try new key completely, if i change it to my given function, it maybe took awhile for the application to generate new key again & the code doesn't even use 100% cpu power, there're no further instruction in the post. Is anybody know to how to adjust the code to check address from mutiple generated key without multiply it. If possible, the performance will stay around like original code or at least decline to 1-20 times, i wouldn't mind that. Thank You

Have anybody try to run vanitygen on Google's TPU cloud machine or any HPC service? What's the best keysearch rates has it archive so far? Huh

Why would you run it online? It is risky to do that because your data could be intercepted.
You should run vanitygen offline on a secure computer. Using OpenCL is fast enough for me.

I think his point is Google's TPU or HPU can generate vanity address at faster rate. While it's true that the information could be intercepted, using encrypted connection could solve the problem.

Using split key is a much better solution, so that Google itself can't know your private key either. They can still know you generated the address through.

I totally forget about split key. But google knowing user generate vanity address doesn't matter unless you could know bitcoin address just from partial private key, brute force to get private from an address with partial private key or have serious privacy concern.

Just want to find out how fast vanitygen can go, hashcat release benchmark & performance of lastest GPU card all the time, i usually use vanitygen to test my GPU card max performance when my family's internet cafe buy a new PC. I always wonder with these days strongest hardware, have we archive the speed of 1bil or even 1 trillion keys/s? Huh

I see. I'm not so sure about the speed but I really doubt we reach that point. 1 billion keys/sec is crazy.
At this moment I can't find the result on the internet either, so your best choice would be to try it out yourself.

But Google's TPU is optimized for AI stuff (deep learning, neural network, machine learning, etc.).

there is zero chance your friend brute forced an entire btc address..

you are just wasting your time.

yeah i know that i dont use it anymore.

In case you try to do this in the future again, dont use half patterns.. The difference between 10^-80 and 10^-60 is almost inexistent, youre better off searching for full patterns rather than maybe landing on a close relative to your address.

possible Bitcoin addresses and you you are looking randomly for 6 million? Have you done the math?

Code:

Read 77 bytes from RNG seed file

and get always the same hash 3b4df4363caa9e3bd9da58020d3080be8230a4ae

so how do you search ?

Are you trying to load a file that contains 6 million patterns to search for?

Can you give us a small sample of the patterns from your file?

of course these are the pattern the first 23 digits from all funded addresses

Why are you running on safe mode the second time? Try removing -S

To quote the response fom this :

Quote

oclVanitygen generates addresses by using OpenCL. OpenCL can run on GPUs, in contrast to C. After OpenCL thinks an address it created has the expected prefix, it passes the private key (actually the delta value of it), the calculated P2PKH hash and the idx value to the C part of the software. When the GPU calculated hash doesn't match the CPU calculated hash, it dumps the info for debugging.

Short Answer: It would, of course, have printed the private key if it had found an address with the expected prefix.

I also don't get what you're trying to achieve using different seeds. You want to find the same patterns from your input file, so regardless of the seed used, if vanitygen finds a pattern that matches the ones in your file, it'll add it. The seeds only help in changing where vanitygen starts to search for a solution, but provided it runs for long enough (and it looks like it'll need a massive amount of years to find what you want) it won't matter anymore.
