From 725 activities · Mar 2026Serpin is the founder and CEO of Ethos, an on-chain reputation protocol addressing trust and accountability in crypto. A 12-year product leader with experience at Atlassian, HouseCallPro, and as an early hire at Message.io (YC W16), he brings deep expertise in product, security, identity verification, and fraud prevention. Known for hands-on community engagement, transparent leadership, and relentless focus on product quality over hype, Serpin actively hosts spaces, responds directly to feedback, and personally vouches for credible users while slashing bad actors. The community consistently highlights his commitment to building something meaningful—detecting Sybils and AI-generated content, designing fair incentive systems, and fostering genuine human connection—rather than chasing quick profits.

Vouched ETH and voucher mechanics will continue evolving as users find new ways to optimize reputation. This adjustment reflects lessons learned over the past 9 months — it strengthens credibility integrity without penalizing genuine, high-conviction support.

I've appreciated our back and forth, and they've been super helpful in giving some advice and tips along the way.

There is no benefit from voting. Turn it off.
