Our Mission & Principles
Fixing the Internet’s Most Vital Protocol
Email connects 4.5 billion people across open, federated servers. But content-based spam filters are dead in the age of generative AI. HumanMail restores trust by proving humanity cryptographically.
The Inbox Collapse
Since LLMs became ubiquitous, malicious AI phishing volume surged by over 1,265%. Scrapers and bot farms generate millions of hyper-personalized cold outreach emails daily for fractions of a cent.
- •Content filters fail: Bayesian and heuristic AI filters cannot distinguish authentic human prose from synthetic language.
- •CEO wire fraud: Executive email impersonation causes over $2.9 billion in enterprise losses annually (FBI IC3).
- •Attention bankruptcy: Knowledge workers spend 45 minutes every day triaging spam and cold outreach.
The Cryptographic Answer
HumanMail (HMP/2.0) introduces an open Proof-of-Personhood standard that mathematically breaks the economics of automated spam swarms while preserving email's decentralized nature.
- ✓Persona-Grade KYC: Biometric liveness and passport NFC verification issue signed credentials binding sender identity to their keypair.
- ✓Strict Anti-Sybil Quotas: Senders are capped at 50 human emails per day—ample for genuine correspondence, impossible for bot swarms.
- ✓Zero-Round-Trip Latency: Recipients verify Ed25519 signatures statelessly in under 0.2ms with zero central database lookups.
Engineered on Four Uncompromising Pillars
Infinite Stateless Scalability
Verification requires no centralized choke point or proprietary blockchain. With O(1) local math, an ordinary CPU core verifies over 4,500 messages per second.
Zero-Knowledge Privacy (ZK-PoP)
Whistleblowers, journalists, and privacy-conscious users can prove 100% biometric humanity while cryptographically withholding their legal name and personal identifiers.
100% Backward Compatible
Attestations travel inside standard RFC 5322 MIME headers (X-Human-Attestation). Legacy servers, Gmail, and Outlook continue to operate without disruption.
Enterprise Mail Gateway (MTA)
Postfix and Sendmail Milter filters intercept traffic at Port 25, injecting standard RFC 8601 Authentication-Results headers and streaming Prometheus threat metrics directly to corporate SOCs.
