It is a awesome evolution for Bitcoin and for the\nCryptoCurrencies as a hole... Thanks!!!\n\n Anyway, I am unable to compile libcoin under my Ubuntu 11.04. At this\nmachine, I have compiled and running Bitcoin (from sources), Namecoin,\nDevcoin, Litecoin, IXcoin and I0coin, all from sources but, when I try to\ncompile libcoin, I got:\n\n----\nuser at

Bitcoiners,\n\u003e\n\u003e libcoin is now in a state ready for its first release, which I would like\n\u003e to share with you!\n\u003e\n\u003e === libcoin is a crypto currency library based on the bitcoin/bitcoin\n\u003e \"Satoshi\" client. ===\n\u003e\n\u003e Copenhagen, Denmark - 1st February 2012 Ceptacle announces the release of\n\u003e the first version of the crypto currency library \"libcoin\" based on the\n\u003e bitcoin/bitcoin \"Satoshi\" client.\n\u003e\n\u003e libcoin also maintains a version of bitcoind that is a 100% compatible\n\u003e drop-in replacement of the bitcoin/bitcoind client: You can use it on the\n\u003e same computer on the same files and you can call it with the same scripts.\n\u003e And you can easily extend it without touching the basic bitcoin source\n\u003e files.\n\u003e\n\u003e The libcoin/bitcoind client downloads the entire block chain 3.5 times\n\u003e faster than the bitcoin/bitcoind client. This is less than 90 minutes on a\n\u003e modern laptop!\n\u003e\n\u003e In libcoin, the Satoshi client code has been completely refactored,\n\u003e properly encapsulating classes, removing all globals, moving from threads\n\u003e and mutexes to a pure asynchronous approach. Functionalities have been\n\u003e divided into logical units and libraries, minimizing dependencies for e.g.\n\u003e thin clients.\n\u003e\n\u003e libcoin is chain agnostic, all chain (bitcoin, testnet, namecoin,\n\u003e litecoin, ...) specific settings are maintained from a single class (Chain)\n\u003e and hence experiments with chain settings, mining, security and digital\n\u003e currencies for research and educational purposes are easily accessible. See\n\u003e the ponzicoin example for how you define your own chain.\n\u003e\n\u003e The build system of libcoin is based on CMake and supports builds of\n\u003e static and dynamic libraries on Linux, Mac OS X, and Windows.\n\u003e\n\u003e The libcoin license is LGPL v. 3. This mean that you can use it in open\n\u003e source as well as in commercial projects, but improvements should go back\n\u003e into the libcoin library.\n\u003e\n\u003e ======\n\u003e\n\u003e Read more on libcoin on: http://github.com/ceptacle/libcoin/wiki\n\u003e\n\u003e Join libcoin on twitter: http://twitter.com/libcoin\n\u003e\n\u003e Download \"libcoin Satoshi release\":\n\u003e http://github.com/ceptacle/libcoin/zipball/v0.4.0.1\n\u003e\n\u003e Best regards,\n\u003e\n\u003e Michael Gronager, PhD\n\u003e Director, Ceptacle\n\u003e Jens Juels Gade 33\n\u003e 2100 Copenhagen E\n\u003e Mobile: +45 31 45 14 01\n\u003e E-mail: gronager at ceptacle.com\n\u003e Web: http://www.ceptacle.com/\n\u003e\n\u003e\n\u003e\n\u003e ------------------------------------------------------------------------------\n\u003e Keep Your Developer Skills Current with LearnDevNow!\n\u003e The most comprehensive online learning library for Microsoft developers\n\u003e is just $99.99!
