Bitsquare is a P2P Fiat-BTC Exchange, extensible to a generic P2P trading platform (include commodities and
cryptocurrencies)

This is just a proof of concept prototype for demonstrating the basic workflow of the trader process.
It is not at all production code style (no tests, verifications missing, very limited use cases,...).

The project use Java 8 and Maven.
2014-05-15 12:31:41 +02:00
We use the bitcoinj library and TomP2P for DHT and messaging.

Test net is currently not working with bitcoinj as the DNS seed servers are not setup correctly (See: http://sourceforge.net/p/bitcoin/mailman/message/32349208/).
To use the RegTest mode you need to set regtest=1 in the bitcoin.config file inside the bitcoin data directory (https://en.bitcoin.it/wiki/Running_Bitcoin).
Then you can generate coins on demand with the Bitcoin qt client with that command in the console: setgenerate true 101 (101 only for the first start because the coin maturity of 100 blocks).
See: https://bitcoinj.github.io/testing
You can change the network mode in the guice module: BitSquareModule.java
