What is Universal Credit System

The Universal Credit System is a new innovative and resource friendly crypto currency. Users process their own blocks and permanently review and audit each other on a file based protocol that allows them to manage themself offline in a decentralised block grid.

The purpose of this document is to show how you can setup and run the UCS wallet.

Technologies used

The program was written as standard shell script (#!/bin/sh).

The script depends on other programs. Most of them are GNU core utilities, which means that depending on your version of the GNU core utils they should be already installed. But some programs (like i.e. bc, openssl, curl and some more) maybe not. During setup the install.sh script will perform a check if any program is missing so you don't need to check them yourself.

The following programs are used:

• awk used to sort/filter data
• basename used to strip directory and suffix from filenames
• bc used for floating point calculations
• cat used to concatenate content
• chmod used to change permissions
• cp used to copy files
• curl used to send query to TSA and request response
• cut used to extract data from streams
• date used for date operations
• dd used to convert files
• dialog used as GUI
• dirname used to strip non-directory suffix from file name
• echo used to write output
• expr used for calculations
• find used to search files/directories
• flock used to manage read locks for multi user setups
• gpg used for transaction signing
• grep used to search files
• head used to display heading lines/bytes of a file
• ls used to list files and directories
• mkdir used to create folders and subfolders
• mv used to move files
• netcat used to send/request files
• openssl used for TSA stamp verification
• printf used to write output
• rm used to delete files
• sed used to modify files
• sha224sum used to hash files
• sha256sum used to hash files
• sort used to sort files
• stat used to get permissions of files/directories
• tail used to display tailing lines of a file
• tar used to create the transaction file
• test used to test files
• touch used to create files
• tr used to convert chars
• umask used to determine umask
• uniq used to filter files
• wc used to count lines, words, bytes
• wget used to fetch certificate files of TSA from Internet

How to install

Assuming you use APT as packaging tool, the command apt-get install is used. Please note that if you are using any other packaging tool than APT the command for installing a package might be different. This means you have the change apt-get install to the command your packaging tool is using!

Install Git (you may use sudo in front):

$ apt-get install git

Create a directory wherever you want and step into this directory:

$ mkdir ucs
$ cd ucs

Clone the GitHub repository and step into this directory:

$ git clone https://github.com/universal-credit-system/wallet
$ cd wallet/

Now you can execute the install.sh script. The script will check for depending programs and if all depending programs are installed the setup will continue. If there is a program that needs to be installed the script will output the program names and then quit. In this case you have to install these programs first and then run install.sh script again.

$ ./install.sh

After setup you can run ucs_client.sh:

$ ./ucs_client.sh
