21  Economy / Marketplace / Re: Don't buy "wallet.dat" files with lost passwords; EXCHANGE THEM. on: January 17, 2021, 12:15:43 PM
I tried to buy one of the cheaper, smaller balance wallet.dat files and the link didn't work.  Something went wrong with satoshidisk.

Is there anywhere else to get these?  Or just one to try out?  I mean one supposedly with a balance but needs decrypting, i.e. guessing a password.

But it should be possible to brute-force bc1 addresses since those also use private keys, if that's not implemented that'll make yet another good science fair project or even a Google Summer of Code project  Grin

Neat idea. I might give that a go and submit a pull request or fork BitCrack with that function. It should be possible.

Edit: my repo is at https://github.com/bitcoinforktech/BitCrack.git which will have some updates in the next few days.
23  Economy / Computer hardware / WTB RTX 3080 card, or RX 5700 XT in Australia on: January 17, 2021, 12:51:13 AM
Looking for a GeForce RTX 3080 or RX 5700XT in Australia.

Offering BTC or direct deposit, Osko or PayID transfer.

Thanks,

See this message. Some function is feeding bad pointers to batchBeginAdd() and batchBeginAddWithDouble(), and these are passed to MulModP() --> copyBigInt() to the point where array access of either of copyBigInt() parameters generates athe Misaligned Access exception everyone here is getting.

It might be something in host code that's giving batchBeginAdd some pointer that's incremented by 1 and not aligned or something. I didn't get a chance to check.

Thanks for that, I suspect it needs some alignment specifiers, e.g. __align__(16) for the data.  I will have to compile myself and test.  I will come back here when I've done that with the results.

Cheers!

Ive compiled cuBitCrack.exe and clBitCrack.exe using 11.2 targets. clBitCrack confirmed working using -t 128 -b 256 -p 1024, if anyone could provide the recommended settings for these cards it would be greatly appreciated! cuBitCrack still not working for 20** and 30** series cards, hoping someone can help me figure it out  Cool

I've done a bit of CUDA development, I might be able to help out.  I have a 3070 card arriving by courier in a few days.

Can you tell me any specific error messages you are getting?   Smiley

Code:
Are you sure you can/cannot convert the key to WIF or somesuch and import it?

Maybe I can, I'm just not very technical.

I also have Parallels, so maybe I can also try installing on Windows or Ubuntu.

It looks like the key as you have described can't easily be exported as a WIF.

I would try Ubuntu rather than Windows for this, if you need to use Parallels.  Windows is a huge pain.

We should be able to do this on Mac with brew.  Fingers crossed those compile issues will get fixed.

Please try

sudo cp /usr/local/opt/openssl@1.1/lib/pkgconfig/*.pc /usr/local/lib/pkgconfig/

My real private key starts with ef and ends in 01.

Code:
python2.7 -m pip install onedrivesdk==1.1.8
https://ibb.co/7gcd0ps

Code:
python2.7 -m pip install blockstack==0.18.0.10
https://ibb.co/Jj0LvnY
https://ibb.co/gzmf2KG
https://ibb.co/8s6mg5S



Thanks guys for all the help.


It looks to me like you need the openssl libraries.  Normally I would 'sudo apt install libssl-dev' and you should be able to do a similar thing with brew. brew install openssl or brew install openssl@1.1.

Try this:

brew install openssl@1.1
cp /usr/local/opt/openssl@1.1/lib/pkgconfig/*.pc /usr/local/lib/pkgconfig/

Hopefully that will help move things along.

Hi SFR10, thanks for that!  Good suggestions.

I had a look around YouTube videos like the one you linked to, it doesn't look too painful... Smiley

Hi,

I am looking for a tidy GPU rig that can accommodate 6, 8 or 12 AMD RX 580 GPUs.  With or without GPUs.

I prefer the box but I will consider a frame rig.

Australian sellers please, postage would probably be really awkward and expensive from overseas...

Thanks!

Updated for Blake hashing.

Also demonstrates changing the hashing algorithm for genesis block creation and the block reward.
