LTsocial V3 (also known as Miracle Network) is a next-generation social media app that combines a three-tier social connection model with blockchain-based monetization. This guide outlines the full product development playbook to bring LTsocial V3 to market – covering frontend UX design, backend architecture, database schema, blockchain integration, and deployment. The app’s design builds upon the V2 Love Transcends Friendship platform, which introduced social tiers (Fanships, Friendships, Inner Circle) and user engagement rules, and extends it with new features like crypto rewards (Miracle Coin), ad revenue sharing, data monetization, a marketplace, and subscription-based fan support. Modern technologies such as React Native/Flutter for cross-platform mobile, Node.js/Express (or Python FastAPI) for backend APIs, PostgreSQL for data storage, Firebase for real-time updates & authentication, and Solidity/Web3 for blockchain components will be used. The following sections break down the system’s requirements and specifications in detail, providing a blueprint for development from UI/UX mockups to smart contracts and DevOps.
