WARNING
===============

This piece of software is provided without warranty of any kind, use it at your own risk.
UBIC is currently "Beta" software, bugs might occur.

# Overview

UBIC is a crypto-project that is meant to democratize currency creation minting new currency in favor of everyone, not only in favor of banks.

UBIC works like basic income on a blockchain, but can also be implemented by other projects for KYC-applications. UBIC will soon allow reliable pseudonymous voting (one person, one vote) and other applications as well that require a functionality to avoid sybil attacks.

Sybil attacks - people receiving multiple basic incomes at once - are harder on UBIC than elsewhere because you are required to prove your uniqueness with a -Non-transferable proof of Signatur-Knowledge- of your E-Passport.

Your identity is NOT revealed to other participants of the system.

The UBIC-Wallet is still in an early stage but does provide all basic functionalities a Wallet requires. You can send transactions, receive them and register a passport in order to get your UBIC cryptoUBI.

If you like the idea of the project you can support its development on github: [UBIC Android wallet source code](https://github.com/rgex/UBIC-android-wallet) &

# Installation on Linux

#### Install dependencies
```
sudo apt-get update
sudo apt-get install git cmake gcc make libleveldb-dev libpcsclite1 libpcsclite-dev libboost-all-dev gcc g++ ntp
```

Verify that libboost is version >= 1.60 using ```apt-cache policy libboost-all-dev``` if it isn't run the commands bellow
```
/!\ only if apt-cache policy libboost-all-dev returns a value below 1.60
cd /usr/local/src
sudo wget https://dl.bintray.com/boostorg/release/1.64.0/source/boost_1_64_0.tar.gz && sudo tar xzvf boost_1_64_0.tar.gz && cd boost_1_64_0
./bootstrap.sh --prefix=/usr/local --with-libraries=all
./b2 install
```

#### Use ntp
```
sudo apt-get install ntp
sudo systemctl enable ntp
```

#### Install OpenSSL 1.1.1d
```
cd /usr/local/src
sudo wget https://www.openssl.org/source/openssl-1.1.1f.tar.gz && sudo tar xzvf openssl-1.1.1f.tar.gz && cd openssl-1.1.1f
sudo ./config -Wl,--enable-new-dtags,-rpath,'$(LIBRPATH)'
sudo make
sudo make install

openssl version # make sure it is version 1.1.1f

#additional steps might be required:
sudo cp /usr/local/lib/libcrypto.so.1.1 /usr/lib
sudo cp /usr/local/lib/libssl.so.1.1 /usr/lib
```

#### Install UBIC
```
cd /usr/local/src
sudo git clone https://github.com/UBIC-repo/core.git
sudo chmod 777 -R core
cd core
cmake CMakeLists.txt
make
sudo make install
```

#### Run the server
```
/etc/init.d/ubic start
```

#### Stop the server
```
/etc/init.d/ubic stop
```

#### Running a node 
If you are using a firewall make sure that port 1334 is open or TCP connections.
This can be ensured by running:

```
sudo ufw allow 1334/tcp
```

#### Open the web interface
To open the web interface you have to open 127.0.0.1:6789/#yourApiKey in your browser.

You will find your api key in the ```~/ubic/config.ini``` file.

/!\ Warning: For security reasons the web interface can not be opened remotely by typing your server ip:6789/#yourApiKey.
If you want to open the web interface of your server do a port forwarding over SSH, and forward the ports 6789 and 12303 to the ports 6789 and 12303 on your local machine.

#### Register a passport
To register a passport go to the "My UBI" tab and click "Register passport", then enter your passport number, date of birth and the date of expiry.
Make sure your NFC reader is plugged and ready, put the passport on top of it. To help you on some readers a green light appears when it found a tag.
Click "Register passport", if it doesnt work try again by turning your passport, opening it. If it still doesn't work open an issue on Github.

Note that to work your node should be synced.

An easier way is to use the Android Wallet App either from the [play store](https://play.google.com/store/apps/details?id=network.ubic.ubic&hl=de) or from [F-Droid](https://f-droid.org/en/packages/network.ubic.ubic/).

Whatever option you choose, please make sure to backup your private keys.

# Command line interface

```
Web interface: http://127.0.01:6789#839073d84f8ee9dbe98d02b3

```ubic status``` will get your current node status.
```
Synced: true
Blockchain height: 4114
Best block hash: 0b9751f604582ddb405e1dfa1cbf202ecbd0621b3b7f9d70ba21456675a017c8
```

```ubic add-peer <ip address>``` will add a new node to your node list.
```

```

```ubic peers``` will return the peers you are connected to.
