Author here. Hey, Hacker News! I'm developing an identity proof system based on the idea of six degrees of separation. I'm writing a series of posts, which I'll then transform into whitepaper.<p>In this post I brainstorm ideas to solve the sibyl attack problem. I believe bringing together location-proof service (FOAM - <a href="https://foam.space/" rel="nofollow">https://foam.space/</a>), staking and face recognition algorithms can solve the problem.<p>Will be happy to hear your thoughts and critique!<p>Previous posts on HN - <a href="https://airtable.com/shrNQ0VClgqBiHmkL" rel="nofollow">https://airtable.com/shrNQ0VClgqBiHmkL</a>
