I tried what you guys suggested and now I am getting hundreds of errors like
undefined reference to 'clRleaseContent' etc
No clue how to get the GPU to work under Windows. Even if it doesn't get these errors, it doesn't find the AMD GPUs.

When I run oclvanitygen.exe 1Test I can hear my video card fan fire up and then I get the exception.
According to Dependency Walker I am using c:\windows\system32\OPENCL.DLL
Anyone have any ideas?
I guess 'standard' vanitygen runs on your system.
I only have the CPU version, this one uses the SSL libaries to perform the ec-point calculations.
The way I made the change has a bug when starting from offset 0.
At each iteration an increment ec-point is added, this increment point is equal to the number hashes in one iteration.
If offset=0 the last entry in the field has a value equal to the increment value during the first iteration,
resulting in a EC-point-add with two equal numbers on the second iteration.
EC-point-add with two equal numbers results in a div#0 error, I'm not sure if the ocl code handles a div#0 like the SSL lib does.
run a tests using an offset.
example an offset of 0x1000 would be:
oclvanitygen.exe 1Test -P 04175E159F728B865A72F99CC6C6FC846DE0B93833FD2222ED73FCE5B551E5B739D3506E0D9E3C7 9EBA4EF97A51FF71F5EACB5955ADD24345C6EFA6FFEE9FED695
Assuming this offset is bigger than the increment value, you avoid the div#0.

This is wonderful, a number too large
I feel sorry to not be involved
Congratulations to those who have joined
I really want to participate in that program
where can I participate in ?
The only thing you need is the pub key of 2^51 or any other point you want to start (example: 2^51 + 2^33) for your start point of the search.
Thanks I will try this with the oclvanitygen, however do you know how to make it detect AMD gpus when compiled with cygwin ?
I installed the OpenCL deps, added the amd.icd to \cygwin\etc\OpenCL\, copied the headers and libraries like so
cp -R '/cygdrive/c/Program Files (x86)/AMD APP SDK'/*/include/CL /usr/include
$ cp '/cygdrive/c/Program Files (x86)/AMD APP SDK'/*/lib/x86/*.a /usr/lib
However it only detects the POCL

Why don't you ask Robert Langdon, I heard he is quite good at this sort of thing 
Well the sequence doesn't make much sense to me as of yet but will try with it a little more later. But in any case, I don't think someone will give out 32 BTC just to solve some puzzle... there must be something else that we don't know or can't see.
Sherlock to rescue maybe?

Cracking it is useless. Its interesting I fully agree, but from economical point of view, you gonna bleed money on every other address. What kept me interested in reading those posts is that this address with over 57K Btc I have found it aswell but on a completely different basis. I was searching for some bitcoins from the very beginning of bitcoin for my own purposes, but I have found this. There is much more wierd patters created by the owner/owners. Literally thousands of unspend 0.01 btc transactions. Clusters of 1 btc transactions, which end up in unspend amounts of 0.005 and so on. I believe the real question here is why would you do that? Someone must have wrote a bot to do that many transactions. Someone must have a file of thousands private keys to thousands addresses - that just does not make things safe.
So why would someone do it? And who is it?
Sounds like a Bitcoin mixer to me. So why would someone do it? And who is it?
Im very bad at programming, all I did was add
const BN_ULONG rekey_max = 10000000000000000;
BIGNUM *bnprivkey, *bnpubkey;
BIGNUM start;
BIGNUM *res;
BN_init(&start);
int keylen = 32;
res = &start;
BN_hex2bn(&res,"6000000000000");
// pkey = EC_KEY_new_by_curve_name(NID_secp256k1);
pgroup = EC_KEY_get0_group(pkey);
pgen = EC_POINT_new(pgroup);
EC_KEY_set_private_key(pkey,res);
if (!EC_POINT_mul(pgroup, pgen, res, NULL, NULL, vxcp->vxc_bnctx));
printf("ERROR AT EC POINT MUL");
EC_KEY_set_public_key(pkey, pgen);
rekey_at = 999999999999999;
Code:
const BN_ULONG rekey_max = 1000000000000000000;
// snip//
while (!vcp->vc_halt) {
if (++npoints >= rekey_at) {
vg_exec_context_upgrade_lock(vxcp);
/* Generate a new random private key */
// remove the random key generation
// EC_KEY_generate_key(pkey);
// add start point equal to 1 * generator
BN_set_word(&vxcp->vxc_bntmp, 1);
EC_KEY_set_private_key(pkey, &vxcp->vxc_bntmp);
EC_KEY_set_public_key(pkey, pgen);
and the second change I made, just to prevent a EC_point add where EC_Point double is needed// snip//
while (!vcp->vc_halt) {
if (++npoints >= rekey_at) {
vg_exec_context_upgrade_lock(vxcp);
/* Generate a new random private key */
// remove the random key generation
// EC_KEY_generate_key(pkey);
// add start point equal to 1 * generator
BN_set_word(&vxcp->vxc_bntmp, 1);
EC_KEY_set_private_key(pkey, &vxcp->vxc_bntmp);
EC_KEY_set_public_key(pkey, pgen);
Code:
if (vcp->vc_pubkey_base){
EC_POINT_add(pgroup,
ppnt[0],
ppnt[0],
vcp->vc_pubkey_base,
vxcp->vxc_bnctx);
EC_POINT_add(pgroup,

}
else{

vxcp->vxc_bnctx);
}
// point 0 and 1 in the array are predefined, start from point 2.
for (nbatch = 2;

nbatch++, npoints++) {

I guess the same change should work in oclvanitygen.
The next point(s) generation code was already sequential and based on the generator point.

until the addresses 50 (1MEzite4ReNuWaL5Ds17ePKt2dCxWEofwk) it was already cracked by someone.
Any ideas what's the formula behind the generation of these addresses?

In continuation to this thread: https://bitcointalksearch.org/topic/brute-force-on-bitcoin-addresses-video-of-the-action-1305887
While playing around with my bot, I found out this mysterious transaction:
https://blockchain.info/tx/08389f34c98c606322740c0be6a7125d9860bb8d5cb182c02f98461e5fa6cd15
those 32.896 BTC were sent to multiple addresses, all the private keys of those addresses seem to be generated by some kind of formula.

1DPUhjHvd2K4ZkycVHEJiN6wba79j5V1u3I wan to try but I'm not a techy person. I have limited knowledge regarding computer programs and coding! But I want to keep track on this puzzle. I want to know who will be the genius that will solve this. 32 BTC is already a big reward for ansering a puzzle
Good luck to everyone! I can't believe no one has cracked this yet (assuming its still even in play).
I saw this thread 2 years ago & assumed it would be cracked before I could get started on it.
Maybe I'll make an attempt at it later, if only for educational purposes & learning on my part.

I think one reason why its not cracked is because you make like 10x more profit just mining ZEC, ETH, XMR, or other GPU coins than brute forcing the 51st bit. For the 52nd bit its 20x more profit, for 53rd bit its 40x more profit.
Another reason is that its hard to get the OCLVANITYGEN to run properly when starting at a custom integer instead of the random key. I asked in that main Vanitygen thread and seems most devs have moved on.
Another issue is speed. Since the program relies heavily on the CPU, if the GPU is inside a 1x slot, then it runs at 50% of its true speed. This is due to the poor lane speed in the 1x slot.

2nd EDIT:
I decided to abandon this project. Basically can't get Oclvanitygen to work in Windows with sequential search and the speeds seem very slow when using a 1x riser. It would take too long to find the 51st key and 52nd and 53rd would take months.
I had a look at the vanitygen code the last couple of day's to see how to make the sequential search.
I just needed a minor change to have the CPU code to run from EC_key=0x01.
Using the online generator at gobittest(dot)appspot(dot)com/VanityAll a key can be made to generate an offset or start code. (for the -P split-key function)
There are still two issue that need to be solved
1) when starting from 1, there are parts of the code that perform an EC_POINT_ADD on two equal value's, here a EC_POINT_DOUBLE is needed.
2) when running multiple threads the old code uses a random key generation to make sure the threads used unique values, currently all my threads run the same data.
1) Is no issue when an offset key is used
2) I just execute the code in single thread, and run the executable #cpu times with another offset start code.
Since I don't have a GPU system I don't know if the change in that code there is just as hard/easy.
I was kind of curious what code changes you made to get it to run.
Im very bad at programming, all I did was add
const BN_ULONG rekey_max = 10000000000000000;
BIGNUM *bnprivkey, *bnpubkey;
BIGNUM start;
BIGNUM *res;
BN_init(&start);
int keylen = 32;
res = &start;
BN_hex2bn(&res,"6000000000000");
// pkey = EC_KEY_new_by_curve_name(NID_secp256k1);
pgroup = EC_KEY_get0_group(pkey);
pgen = EC_POINT_new(pgroup);
EC_KEY_set_private_key(pkey,res);
if (!EC_POINT_mul(pgroup, pgen, res, NULL, NULL, vxcp->vxc_bnctx));
printf("ERROR AT EC POINT MUL");
EC_KEY_set_public_key(pkey, pgen);
rekey_at = 999999999999999;
The transactions seem to originate from address 173ujrhEVGqaZvPHXLqwXiSmPVMo225cqT which had a Total received amount of 56,457.80848111 BTC and a Final Balance of 312.04932734 BTC
Definitely a very big player of some kind.

Well spotted.
Also it looks active, there are daily transactions there.
Probably some exchange?
Well, now it's have total received 64,770.80848111 BTC
And Final Balance 4.72027689 BTC
Since, we mentioned so much about it. The owner move and divide his funds around, not interested to check all of them.
May not look like as exchange, probably just a trader. How lucky they are who had such big amount of bitcoin.

Finally got vanitygen AND oclvanitygen to start at a custom integer for the private key
I had some weird issue before with the POINT or the GROUP functions. That and I am really not good with Pointers.
Now just need to do some Optimizations to make it go faster.
Really hope to solve the 51st part of the puzzle.

I've got a 4 GPU rig sitting here doing nothing.
Yeah I can't get it to work under windows for my GPUs. For some reason CYGWIN only seems the CPU.
So far scanning the 51st key
10 billion keys scanned and haven't hit it yet. Way too slow with CPU.
EDIT:
Scanned 42 Billion keys and not hit yet. I started with hex 6000000000000, which is 50% in the middle of the range.
Still working on getting the GPU miner to work however running into issues and rather not resort to Linux at the moment.

I have seen some of these before and I have to ask, how do you solve things like this. Is there a method or general way to go about looking at this. All this is to me is numbers and letters. None of it makes sense to me, but I would like it to make sense.

char b1[] = "0";
Did you try starting with one? 0 * G is a special case for the scalar multiply over the point group so try starting with one instead.
Problem is I can't remove
EC_KEY_Generate_key(pkey)
Because I get segmentation fault
I need to leave that in there and just add
BN_init(&start);
ctx = BN_CTX_new();
res = &start;
BN_hex2bn(&res,"1");
EC_KEY_set_private_key(pkey, res);
But I keep getting delta errors on the GPU miner and with the CPU miner the pattern I search for doesn't equal to the result I get, but it actually starts with 1 private key.
I think the issue is that I also can't include
pkey = EC_KEY_new_by_curve_name(NID_secp256k1);
Because I get segmentation faults also.
