Bitcoin Blockchain information program

A simple Python Block Clock to check the Blockchain information.

a@A:~> pip3 install -r requirements.txt

• Install the Hexyl

• python3 PyBlock.py

• First log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase:

1. a@A:~> ssh-keygen -t rsa
  Generating public/private rsa key pair.
  Enter file in which to save the key (/home/a/.ssh/id_rsa): 
  Created directory '/home/a/.ssh'.
  Enter passphrase (empty for no passphrase): 
  Enter same passphrase again: 
  Your identification has been saved in /home/a/.ssh/id_rsa.
  Your public key has been saved in /home/a/.ssh/id_rsa.pub.
  The key fingerprint is:
  3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A

• Now use ssh to create a directory ~/.ssh as user b on B. (The directory may already exist, which is fine):

2. a@A:~> ssh b@B mkdir -p .ssh
   b@B's password: 

• Finally append a's new public key to b@B:.ssh/authorized_keys and enter b's password one last time:

3. a@A:~> cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
   b@B's password: 

• From now on you can log into B as b from A as a without password:

4. a@A:~> ssh b@B

After this process you can execute Python-Blockclock.py

It will appear a place you can put your Bitcoin-cli path

• "Path to your Bitcoin-cli: " #Add the path and shoot Enter.
