a.s.d.f

a.s.d.f is your neighborhood, live — the local layer for everywhere you go. Instead of global feeds and noisy marketplaces, every zip code gets a private, real-time network where you can see what's happening nearby, talk to locals, buy and sell, discover events, find deals, and ask AI about your area. Content stays where it's useful — local and trusted.

SEE WHAT'S HAPPENING AROUND YOU

Your home screen is a live local dashboard: weather, nearby events, hot zones, a local map, and your zip-code rooms — an instant answer to "what's happening near me right now?"

LIVE ZIP-CODE ROOMS

Join real-time rooms by zip code to ask about a street, an event, a lost dog, traffic, or a good plumber. Rooms are localized, socket-powered, and end-to-end encrypted. A room limit keeps things relevant and spam-free while letting you follow home, work, and places you travel.

LOCAL CLASSIFIEDS

Buy, sell, and ask locally. Post for-sale items, services, housing, jobs, lost & found, and notices — visible only in your zip code and surrounding areas. Browse by category, save favorites, and message sellers privately through encrypted chat.

DEALS NEAR YOU

Discover relevant offers from local businesses and partners — deals tied to where you live, work, and move, not random ads.

ASK AI ABOUT YOUR AREA

A local AI assistant turns discovery into a conversation: "What's happening near me today?" "Find deals around me." It connects rooms, events, deals, classifieds, and the open internet into one local command layer.

PUBLIC SHORTS

Watch and post short, reel-style local videos from your area — a live look at your neighborhood. Even these public reels are end-to-end encrypted.

PRIVATE & GROUP MESSAGING

Message anyone with end-to-end encrypted DMs — text, photos, videos, voice, GIFs, stickers, and live location. React, reply with quotes, and see read receipts. Create private groups or join public topic rooms; an accept-first model keeps unwanted messages out.

END-TO-END ENCRYPTED, EVERYWHERE

Privacy isn't a setting — it's the foundation. Public room reels, chats, and topics are all end-to-end encrypted by the Fourier Protocol, our zero-knowledge system built in Rust using the same proven cryptography behind Signal. The server never holds plaintext or the keys to derive it. It implements the full Signal Protocol stack:

- X3DH (Extended Triple Diffie-Hellman) key agreement with offline recipients
- Double Ratchet for forward secrecy and post-compromise security
- Sender Keys for O(1) encrypted group messaging up to 1,000 members
- X25519 elliptic-curve Diffie-Hellman for key exchange and ratcheting
- Ed25519 signatures for identity authentication and verification
- ChaCha20-Poly1305 AEAD encryption for direct messages
- AES-256-GCM encryption for public group messages
- HKDF-SHA256 key derivation for per-message keys
- SHA-256 fingerprinting for safety-number verification
- Message padding to resist traffic analysis
- Cryptographically secure RNG for nonces and key material

Your keys never leave your device. Not even we can read your messages. Verify contacts with 60-digit safety numbers.

EVENTS & COMMUNITY

Create and discover local events with details, itineraries, and RSVP tracking. Join topic-based communities around sports, music, tech, gaming, food, travel, and more.

PROFILES

Build a trusted local profile with a photo gallery, bio, and location. Verify your identity — real neighbors, not anonymous accounts.
