Implementation of the BitNym protocol as a JAVA library.
BitNym is described in:
M. Florian, J. Walter, I. Baumgart (2015) Sybil-Resistant Pseudonymization and Pseudonym Change without Trusted Third Parties. Proceedings of the 14th Workshop on Privacy in the Electronic Society (WPES) (https://dl.acm.org/citation.cfm?id=2808138.2808145)
The library is useable but hasn't been extensively tested yet. If you encounter any problems or bugs, feel free to file a issue on https://github.com/kit-tm/bitnym
Use at your own risk! In its current state, you probably shouldn't trust this library to provide perfect anonymity.
