I have been working on Blockchain and cryptocurrency since 2017 as a research scholar at the Indian Institute of Technology (IIT) Hyderabad. I have been working on the scalability issues in public blockchains like Bitcoin and proposed a DAG-based consensus algorithm using graph clustering algorithms. I worked on a stateless UTXO based blockchain and named as a compact chain. I have used ZK-SNARKs for proving the assets of a crypto exchange without revealing the privacy of the exchange.
