BTCplex is an open source Bitcoin block chain browser written in Go, it allows you to search and navigate the block chain. Also provides APIs to access data pragmatically.

This is an early release, you might expect some bugs.

## Requirements

• A bitcoind instance (you can build bitcoind in Disable-wallet mode)
• Go >=1.2
• Redis 2.6+
• SSDB
• LevelDB
• 150+GB disk space / 4+GB RAM

Building BTCplex database takes 1+ week on a small server (dual core 1.2GHz/6GB RAM) and 28 hours on a more powerful server (i5/16GB RAM).

## Installation

Assuming you have:

• a working Go workspace (and $GOPATH already set)
• Redis 2.6+
• SSDB
• LevelDB (nice tutorial)
• Snappy

You will also need to export CGO_LDFLAGS, needed to install levigo.

$ git clone https://github.com/tsileo/btcplex.git
$ cd btcplex
$ export CGO_LDFLAGS="-L/usr/local/lib -L/usr/local/lib -lsnappy"
$ ./build.sh
$ cp -r config.sample.json config.json
$ vim config.json

Start the initial import (the example use nohup, but you should use a tool like supervisord):

$ nohup ./bin/btcplex-import > import.log&

And once the process is done, you will have to restart you bitcoind with the -blocknotify``` parameter: -blocknotify="/home/thomas/btcplex/bin/btcplex-blocknotify -c /home/thomas/btcplex/config.json %s". Now you can start btcplex-prod``:

$ nohup ./bin/btcplex-prod > prod.log&

Even while importing, you can start the webserver:

$ ./bin/btcplex-server

• Stabilize everything for 1.0 release.
• Make sure a transaction can't be processed multiples times
• A receive payment API

Some features that are on my TODO list:

• An easy way to monitor Bitcoin address via API (maybe using Webhooks)
• Convert BTC to fiat money easily
• An official Python module to interact with the API and offer a reliable way to track address
• An official JS lib to interact with the API
• A Watch-only addresses page
• Display unconfirmed transactions on address page
• Live notification on a unconfirmed transaction page when it actually get included in a block
• Parse the coinbase to extract which pool mined the block
• An admin interface to monitor bitcoind/BTCplex
• New SSE endoind: utxin/utxout for a given address
• Escrow transaction handling
• Docker build
• Provides supervisord config
• ... (don't hesitate to request features!)
