You first need to install the libraries this app uses:
# sudo apt-get install git make clang libssl-dev
# sudo apt-get install libcurl4-openssl-dev libncurses5-dev
# sudo apt-get install libleveldb-dev libsnappy-dev
# sudo apt-get install libstdc++-4.8-dev
then clone the git repository:
# git clone https://github.com/bit-c/bitc.git
finally build and launch:
# cd bitc && make
# ./bitc
You need to install libcurl, leveldb, libsnappy and ncurses via port or brew.
The first time you launch the app, a message will notify you of the list of files & directory it uses.
bitc uses the folder ~/.bitc to store various items:
| what | where | avg size |
|---|---|---|
| block headers | ~/.bitc/headers.dat | ~ 20MB |
| peer IP addresses | ~/.bitc/peers.dat | ~ 2MB |
| transaction database | ~/.bitc/txdb | < 1MB |
| config file | ~/.bitc/main.cfg | < 1KB |
| wallet keys | ~/.bitc/wallet.cfg | < 1KB |
| tx-label file | ~/.bitc/tx-labels.cfg | < 1KB |
| contacts file | ~/.bitc/contacts.cfg | < 1KB |
A log file is generated in /tmp/bitc-$USER.log.
To navigate the UI:
<left>and<right>allow you to change panel,<CTRL>+ T to initiate a transaction,- type
qorback quoteto exit.
bitc has support for encrypted wallets. The first time you launch the app, it will automatically generate a new bitcoin address for you, and the wallet file will have private key unencrypted.
To turn on encryption, or to change the encryption password:
# ./bitc -e
The next time you launch the app, you may or may not specify -p on
the command line. If you do, you will be able to initiate transactions. If you
do not the dashboard will still be functional but you won't be able to
initiate transactions.
Note that bitc encrypts each private key separately.
WARNING: please remember to make back-ups.
You need to modify your ~/.bitc/wallet.cfg so that it contains the private
key as exported by bitcoin-qt with the command dumpprivkey. More on that
later.
There are still a variety of things that need to be fixed or implemented (cf TODO file), and some of these may explain the behavior you're seeing. If bitc crashes, please collect the log file along with the core dump and open a ticket on github:
