Hello World,

I had started working on this blog dedicated to Hal Finney in August: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2021-August/019367.html

I have been able to track more than 10 Issues and Pull Requests from different Bitcoin projects that are focused on privacy. Wrote 3 blog posts and will write more often as I learn new things. There is a section called 'Hall of Fame' and 7 developers are listed in hof who worked on one or more pull requests that helped improve privacy in Bitcoin projects: Andrew Chow, chimp1984, jmacxx, Luke Dashjr, Samuel Dobson, Vasil Dimov and wpaulino.

Last post is about 'Rebroadcast mechanism' used in Bitcoin full node implementations: https://prayank23.github.io/camouflage//blog/rebroadcast/

Problem: Rebroadcast mechanism used in Bitcoin Core and Knots, rebroadcasts only our transactions. This helps spy nodes to link bitcoin addresses with IP addresses and also know that wallets are enabled for a node.

Solution by Amiti Uttarwar: New rebroadcast mechanism in which transactions are re-broadcasted based on fee rate and mempool age.

I have shared other details, my opinion and links to comments by Suhas Daftuar in the blog post since related pull request has been in draft mode for some time now.
