There are many groups working on solving this problem, which is analogous to how SSL was developed atop the unencrypted lower layers of TCP/IP stack. One experimental option is Aztec https://docs.aztecprotocol.com/ https://docs.aztecprotocol.com/ Most of the solutions use zkSNARKs, which is a generic solution for privacy preserving functions in public settings https://blog.zkga.me/intro-to-zksnarks https://blog.zkga.me/intro-to-zksnarks Tornado.cash is a popular mixing services that anonymizes cryptocurrency and tokens in the Ethereum network to preserve privacy https://tornado.cash/ https://tornado.cash/ > Done jerking yourself off? Now do some real work. I have been on this website for years, and the hate cryptocurrency / blockchain gets is absurdly high, and I believe it mostly comes from bitter people who think they missed out on fast money and now have to constantly justify why they (and everyone else) should completely avoid this technology. Blockchain is literally building an alternative financial system, one that is unstoppable and without government permission. It is decentralized and fascinating. If you choose to learn about it rather than write it off with a smug look on your face, you may actually learn and understand why it's useful. On HN it's a 95% to 5% ratio of blockchain haters to neutral / positive people. However most crypto enthusiasts avoid HN because everyone knows it's anti-crypto. HN has missed the boat on a hugely important and transformative technology because a loud portion of its users have irrational, spittaling rage at blockchain and believe they are so smart that they can 100% guarantee that the tech is worthless, despite it being one of the greatest pure computer science successes of the 21st century. HN is an SV echo chamber that promotes the YC view of the world, which I believe was once revolutionary but is now becoming stale and eating itself, as is most of the tech echo chamber.
