五大核心進化機制
告別傳統笨重、容易被 OCR 繞過之傳統驗證碼機器人。Portico 以雲端邊緣原生技術重塑門禁生態。
Dynamic Anti-OCR Captcha & Button Scrambling (/verify)
Real-time edge rendering of rotated, sine-distorted verification captchas with random button position shuffling to block automated spambot scripts.
Gasless Web3 Wallet Signature & Anti-Sybil (EIP-4361 SIWE)
Support zero-gas EIP-4361 SIWE signatures via MetaMask and Phantom. Strict 1 wallet to 1 account binding prevents Sybil airdrop farming.
Branching Role Wizard & Channel Previews (/role-picker)
Multi-step questionnaire guides newcomers into role-gated domains with real-time unlocked channel previews and auto-generated icebreaker cards.
Anti-Raid Lockdown & Ghost Member Purge (/raid-mode)
Automatic lockdown activates when 30+ accounts join within 10s. Automated Cron schedules periodically purge inactive ghost roles (>30 days).
