Revolutionary way to fight spam!
nCaptcha is a decentralized, Web3-based CAPTCHA system built on NEAR Protocol. Instead of puzzles, it uses micro‑transactions and on‑chain reputation to stop bots. The result? Better protection, smoother UX.
🔄 How It Works
1. Micro‑PaymentsUsers pay a tiny fee (fractions of a cent) to verify they’re human. This cost deters bots from spamming—because at scale, it gets expensive.
2. Reputation-Based AccessTrusted users build on‑chain reputation. Once verified, future interactions can skip payments entirely, keeping things frictionless.
