PostHub

PostHub is a Web2-style consumer content app powered by Web3 infrastructure. It is designed for people to share real, trustworthy, and media-rich guides to solve everyday life problems — like buying SIM cards abroad, using public transport in a foreign country, finding non-touristy restaurants, or completing everyday tasks that aren’t easily explained by search engines or AI.

Unlike AI or search engines that generate generic, spam-prone, or sometimes false results, PostHub puts real humans back at the center of everyday knowledge sharing. Users create posts with markdown-formatted text, images, and videos, explaining solutions in a clear and engaging way. Each post can be liked, starred, commented on, and tipped using crypto — encouraging authentic content that actually helps.

To further incentivize quality posts, every week, PostHub calculates the top 5 most liked/starred posts and randomly selects one winner using Flow VRF (Verifiable Random Function). The winner receives a 500-token reward, creating a fair and gamified ecosystem that encourages contribution.

🔑 Key User Features:

• Helpful post creation: Markdown + media support.
• Likes and stars: Social proof and ranking.
• Crypto tipping: Send stablecoins as appreciation.
• Weekly rewards: One post out of top 5 wins 500 tokens.
• Commenting system: Includes image-based replies.
• POAP badges: Users can attach collectible badges to experiences.

👥 Personalized User Experience:

PostHub ensures that every user has a custom-tailored experience based on their age, gender, and country — collected optionally via Self.xyz. For example:

• Under 18: No adult or gambling content shown.
• Over 55: Interface scales up for accessibility (larger fonts).
• From sanctioned countries: Can browse but not send/receive gifts (crypto).
• Gender: Used to fine-tune content recommendations.

Despite these controls, PostHub is inclusive: even if users skip customization, they can still use the platform with limited functionality.

PostHub’s mission is simple: Bring back real, human-centric trust to everyday knowledge — and reward those who help others.

PostHub is architected to combine the smooth experience of a Web2 consumer app with the integrity, verifiability, and incentivization of Web3. Every component is designed to feel natural to average users — even those who don’t know what blockchain is — while leveraging blockchain under the hood for trust, traceability, and fair rewards.

🔗 Flow Blockchain

PostHub uses Flow for:

• ✅ On-chain metadata:

  • Each post’s title, timestamp, user hash, and other identifiers are stored immutably on-chain.
  • This proves authorship, prevents tampering, and enforces accountability (you can’t deny what you posted).

• 🎰 VRF (Verifiable Random Function):

  • Weekly, the top 5 posts (based on likes and stars) are entered into a fair draw.
  • Flow’s VRF selects one post to receive a 500-token reward.
  • Ensures provable fairness in community incentives.

• 💸 Token handling:

  • Users can send mock stablecoins (e.g., USDC) as tips.
  • Posts that resonate with others become income-generating content.

🆔 Self.xyz

PostHub uses Self.xyz to collect optional user data in a verifiable yet user-friendly way:

• 🧒 Age: Determines access to sensitive content (no 18+ material for minors).
• 🌍 Country: Users from restricted regions can browse but not send/receive crypto gifts.
• 🚻 Gender: Used to improve content recommendations (e.g., makeup vs. automotive posts).

This enables 12 distinct user types, each with tailored UX — yet ensures no user is fully excluded.

🔐 Privy

Privy powers authentication and identity on PostHub:

• 🔓 Email-based login for Web2 users (no crypto wallet required).
• 🪙 Wallet login for crypto-native users.
• 🔄 Non-custodial identity that can be verified later — you can skip identity setup and come back anytime.

This ensures seamless onboarding, whether you’re crypto-savvy or completely new.

🗄️ Supabase (Off-Chain Storage)

PostHub uses Supabase for:

• 📦 Storing post content (markdown, media files)
• 🔍 Indexing for full-text search and filtering
• 🤖 Feeding recommendation algorithms
• 💬 Managing comments, reactions, and notifications

Posts are stored off-chain to ensure speed and cost-efficiency, while critical metadata is hashed and stored on-chain.

🖥️ Front-End Experience

PostHub’s front end is built using Next.js (React) and designed with a mobile-first, creator-friendly UX:

• 📱 Feed-based browsing, familiar to TikTok, Xiaohongshu, and Reddit users
• ✍️ Markdown editor with media upload for easy post creation
• 🖼️ Comments with images (replies with visual proof)
• 🛠️ Customizable profile page (likes, stars, badges, ENS name)
• 📩 Notification center (for POAPs, comments, tipping alerts, reward wins)

Everything looks and feels like a familiar Web2 app — but trust, rewards, and accountability come from Web3.
