Babel Framework

Babel is a framework to develop, implement, and execute distributed protocols and systems.
It promotes an event driven programming and execution model that simplifies the task of translating typical specifications or descriptions of algorithms into performant prototypes, while allowing the programmer to focus on the relevant challenges of these algorithms by transparently handling time-consuming low level aspects.
The framework and usage examples are available at: https://github.com/pfouto/babel-core
