Burstcoin Wallet

The world's first HDD-mined cryptocurrency using an energy efficient and fair Proof-of-Capacity (PoC) consensus algorithm.

This wallet version is developed and maintained by the PoC consortium (PoCC) and supports a multitude of database backends. The two builtin backends are:

• MariaDB (recommended)
• H2 (embedded, easier install)

Other DB backends are supported by the Burstcoin DB manager: https://github.com/PoC-Consortium/burstcoin-db-manager

Software Installation

Linux (Debian, Ubuntu)

• fetch the newest release ZIP file

If running for the first time,

• install Java
• install MariaDB
• run burst.sh help
• probably you want to do burst.sh import mariadb

if upgrading your wallet config from 1.3.6cg

burst.sh upgrade

will take the old nxt-default.properties/nxt.properties files and create brs-default.properties.converted/brs.properties.converted files in the conf directory. This should give you a headstart with the new option naming system.

Windows

MariaDb

In the conf directory, copy brs-default.properties into a new file named brs.properties.

Download and install MariaDB https://mariadb.com/downloads/mariadb-tx

The MariaDb installation will ask to setup a password for the root user. Add this password to the brs.properties file created above in the following section:

DB.Url=jdbc:mariadb://localhost:3306/brs_master
DB.Username=root
DB.Password=YOUR_PASSWORD

The MariaDB installation will also install HeidiSQL, a gui tool to administer MariaDb. Use it to connect to the newly created mariaDb server and create a new DB called burstwallet.

MacOS

BRS can be installed using a Homebrew formula. A short tutorial on how to install BRS using homebrew can be found at ecomine.earth/macos.

A number of other Hombrew formulas (written by Nixops) are also available for plotters and miners.

Other Unix-like systems

Please install Java 8 (JRE 1.8) manually and run the wallet by using burst.sh You can get further information calling burst.sh help

A good HowTo for running the wallet on a mac can be found here https://www.reddit.com/r/burstcoin/comments/7lrdc1/guide_to_getting_the_poc_wallet_running_on_a_mac/

Configure and Initialize MariaDB

The Debian and Ubuntu packages provide an automatic configuration of your local mariadb server. If you can't use the packages, you have to initialize your database with these statements:

echo "CREATE DATABASE brs_master; 
      CREATE USER 'brs_user'@'localhost' IDENTIFIED BY 'yourpassword';
      GRANT ALL PRIVILEGES ON brs_master.* TO 'brs_user'@'localhost';" | mysql -uroot
mysql -uroot < init-mysql.sql

Configure your Wallet

Now you need to add the following stuff to your conf/brs.properties:

DB.Url=jdbc:mariadb://localhost:3306/brs_master
DB.Username=brs_user
DB.Password=yourpassword
