The project is part of the project of the Distributed Systems and Reliable Networks Research Lab (DISNET) at Koç University.

LightChain is a DHT-Based Blockchain implemented over a Skip Graph overlay. It was designed but the DISNET Lab, and it has several state of the art features.

Our task was to implement a proof of concept for this design.


You may find the details of our implementation and architecture in our demo paper here, which was presented in IEEE International Conference on Blockchain and Cryptocurrency, 2020.
