Bells (BEL)

Bells is a peer-to-peer electronic cash system forked from Litecoin, using scrypt as its proof-of-work algorithm and DigiShield for per-block difficulty retargeting. This repository contains the Bells 0.8.7.1 reference client: bellsd (headless daemon) and bells-qt (graphical wallet).

Project status

Bells 0.8.7.1 is the final release of the 0.8.x codebase (2014). It is a legacy codebase and is no longer under active development, but it is kept buildable so that old wallets and block chain data remain accessible.

The tree has been updated to compile with a current toolchain:

Component	Version used for the Windows release builds
Compiler	GCC 13.2 (MinGW-w64, x86_64 and i686)
Boost	1.83.0
Berkeley DB	4.8.30.NC
OpenSSL	1.0.2u
LevelDB	bundled in `src/leveldb`
Qt	5.15.2 (MinGW builds)

Source compatibility patches for Boost 1.83 / Qt 5 / modern MinGW are included in this repository. See doc/build-msw.md for the exact Windows build procedure.

Prebuilt Windows binaries are available on the releases page:

bells-0.8.7.1-win64.zip - 64-bit build (x86_64)
bells-0.8.7.1-win32.zip - 32-bit build (i686)

Coin specification

Parameter	Value
Proof of work	scrypt
Block target time	2.5 minutes
Difficulty retargeting	every block (DigiShield)
Total supply	500,000,000 BEL
P2P port (mainnet)	19919
RPC port (mainnet)	19918
P2P port (testnet)	29919
RPC port (testnet)	29918
Address prefix	`B`
Protocol version	70002
Data directory (Windows)	`%APPDATA%\Bells`
Data directory (Unix)	`~/.bells`
Configuration file	`bells.conf`

Block rewards

Each block pays one of the following rewards, selected at random:

Probability	Reward
50%	50 BEL
20%	100 BEL
14%	250 BEL
10%	500 BEL
5%	1,000 BEL
1%	10,000 BEL

The schedule changes at the following heights:

block 129,600 (~90 days): reward halved
block 259,200 (~180 days): reduced to 4/5
block 518,400 (~1 year): fixed reward of 2 BEL

Getting started (Windows)

Download and unpack the archive for your architecture. Keep all files and subdirectories together; the executables will not start without the bundled Qt libraries and the platforms directory.
Run bells-qt.exe for the graphical wallet, or bellsd.exe for the daemon.
On first start the client creates its data directory and wallet.dat:
```
%APPDATA%\Bells
```
Back up wallet.dat before using the wallet with real funds.

Portable mode is available with -datadir=<path> (for example bells-qt.exe -datadir=D:\BellsData).

Running the daemon

bellsd.exe                  run in the current console (Ctrl+C to stop)
bellsd.exe --help           list all command line options
bellsd.exe getinfo          example RPC call

Windows does not support Unix-style daemonization, so -daemon has no effect. Use start /b bellsd.exe to run the daemon without a separate console window.

Configuration

Settings are read from %APPDATA%\Bells\bells.conf (or -conf=<file>). A minimal server configuration:

server=1
rpcuser=username
rpcpassword=change-me
rpcallowip=127.0.0.1
rpcport=19918
port=19919
# addnode=1.2.3.4:19919
# listen=1
# upnp=0

The daemon and the GUI can share the same data directory, but only one process may open the wallet at a time.

Common command line options

Option	Description
`-datadir=<dir>`	Use an alternative data directory
`-conf=<file>`	Use an alternative configuration file
`-testnet`	Connect to the test network
`-connect=<host>`	Connect only to the given node
`-listen=0`	Do not accept incoming connections
`-rpcuser` / `-rpcpassword`	RPC credentials
`-rpcallowip=<ip>`	Allow RPC connections from the given address
`-gen=0`	Disable mining (mining is off by default)

A full list is printed by bellsd.exe --help.

Building from source

The build produces two targets:

src/bellsd (or bellsd.exe on Windows) - headless daemon
bells-qt (or bells-qt.exe on Windows) - Qt wallet, built from bitcoin-qt.pro

Detailed platform notes:

doc/build-msw.md - Windows, native MSYS2 or cross-compile from Linux
doc/build-unix.md - Linux and other Unix-like systems
doc/build-osx.md - macOS

Berkeley DB 4.8 is required for wallet compatibility. Newer Berkeley DB versions change the wallet file format and must not be used.
