The respected programmer and cryptographer "Hal Finney" was mentioned on the cryptanalysis portal "CRYPTO DEEP TECH". They wrote very warm and high words about him. The topic of discussion was "Speed up secp256k1 with endomorphism" . This is what "Hal Finney" laid as the foundation for deep research in cryptanalysis. I respect, remember and love him!

Hello to all experts and miners. More recently, I came across the "bitcoin-mining-python-Google-Colab" repository on GitHub. Hypothetically, can we mine cryptocurrency with the Free Google Colab GPU? Most cloud mining schemes give good results in the production of cryptocurrencies. In the developer forums, many praise Tensorflow, I could use your advice.

What is these post up to?
Who has that address and do you think you could use people to gain wealth for yourself 🙄


This is a puzzle of 120 but with modified public key. So now públic key not 120 bit, but a Mach smaller then 120 bit. Find a prickly, Publix’s in this thread and we get 1.2 btc

Who is the owner of that 1.2 BTC?

AGD what are you falling for this nonsense? This dude under the nickname "Manosuper" on GitHub is pursuing his own selfish goals. Do not pay attention!

kangaroo work with only one key.

You can run on a large list of public keys.

Code:

@Echo Off
COLOR 0A

SET file=PublicKey0001.txt

setlocal enabledelayedexpansion

SET sessFile=_session.txt

SET Npubkey=0
echo [~] calc total Npubkey in file "!file!" ..
For /F %%a In (%file%) Do (
SET /a Npubkey+=1
)

SET lastN=0
IF EXIST !sessFile! (
SET /P lastN=)

SET n=0
For /F %%a In (%file%) Do (
echo =================================================
REM date /T && time /T
powershell Get-Date
echo [!n!/!Npubkey!] %%a

IF !lastN! == !n! (
echo !n!>!sessFile!

C:\Python37\python.exe pollard-kangaroo.py 32 %%a
REM timeout /T 1

SET /a lastN+=1

Re: It is necessary to find one private key out of 10 million Bitcoin Addresses

I managed to decrypt the public keys for each Bitcoin Address from the list.

Public keys: https://drive.google.com/drive/folders/1HByDJR9Ck5CdIwTl-v_IzcaVhsG8aKaA

Now I will try to extract a few private keys through the "Baby-step Giant-step" method.


What software do you use the Baby-step Giant-step method?
