PSync is a C++ library for name synchronization that implements the `PSync protocol
<https://named-data.net/wp-content/uploads/2017/05/scalable_name-based_data_synchronization.pdf>`__.
It uses Invertible Bloom Lookup Table (IBLT), also known as Invertible Bloom Filter (IBF),
to represent the state of a producer in partial sync mode and the state of a node in full
sync mode. An IBF is a compact data structure where difference of two IBFs can be computed
efficiently. In partial sync, PSync uses a Bloom Filter to represent the subscription of
list of the consumer.

PSync uses the `ndn-cxx <https://github.com/named-data/ndn-cxx>`__ library.
