Summer of Bitcoin where I have been working under mentors along with my peers to contribute towards the fascinating world of cryptocurrencies. My area of focus is Bitcoin-core and the work revolves around contributing to the Bitcoin. I have been actively reviewing the features focusing GUIX and am also working on improvising the fuzz tests. I have also been exploring the Onion Service and how to run Bitcoin Core on the Tor network, which helps in getting another layer of security to all the nodes.
