Dear Bitcoiners,

libcoin is now in a state ready for its first release, which I would like t= o share with you!

=3D=3D=3D libcoin is a crypto currency library based on the bitcoin/bitcoin= "Satoshi" client. =3D=3D=3D

Copenhagen, Denmark - 1st February 2012 Ceptacle announces the release of t= he first version of the crypto currency library "libcoin" based o= n the bitcoin/bitcoin "Satoshi" client.

libcoin also maintains a version of bitcoind that is a 100% compatible drop= -in replacement of the bitcoin/bitcoind client: You can use it on the same = computer on the same files and you can call it with the same scripts. And y= ou can easily extend it without touching the basic bitcoin source files.
The libcoin/bitcoind client downloads the entire block chain 3.5 times fast= er than the bitcoin/bitcoind client. This is less than 90 minutes on a mode= rn laptop!

In libcoin, the Satoshi client code has been completely refactored, properl= y encapsulating classes, removing all globals, moving from threads and mute= xes to a pure asynchronous approach. Functionalities have been divided into= logical units and libraries, minimizing dependencies for e.g. thin clients= .

libcoin is chain agnostic, all chain (bitcoin, testnet, namecoin, litecoin,= ...) specific settings are maintained from a single class (Chain) and henc= e experiments with chain settings, mining, security and digital currencies = for research and educational purposes are easily accessible. See the ponzic= oin example for how you define your own chain.

The build system of libcoin is based on CMake and supports builds of static= and dynamic libraries on Linux, Mac OS X, and Windows.

The libcoin license is LGPL v. 3. This mean that you can use it in open sou= rce as well as in commercial projects, but improvements should go back into= the libcoin library.
