Keplereum is a decentralized satellite communication system built on Ethereum blockchain technology. It allows ground stations to track and manage their satellites each through a dedicated private Ethereum Proof-of-Authority (PoA) blockchain, ensuring secure, tamper-proof, and efficient data transmission.

This is a Proof of Concept model of Blockchain Technology based E-Voting System. It was our Computer Networks Project at "School of Engineering and Applied Science", Ahmedabad University.

Application to add Blockchain (ethereum) functionality in Thingsboard (IoT) platform. It is part of Winter Internship at Komhar Technologies.

It simulates a shared/distributed ledger (a.k.a. block chain) network of nodes (full nodes/miners and thin clients) to better understand how this type of protocols work (e.g. Bitcoin, Ethereum, etc)
