Hup

Here is a highly tailored, technical submission draft written specifically for Hup, structured to align with the high-performance expectations of the Monad Builder Program. 1. What did you build? I built Hup, a fully on-chain, censorship-resistant, decentralized social networking protocol designed for high-throughput execution. Hup features a secure, privacy-first infrastructure that integrates signature-based authentication, metadata-free interaction patterns, and an integrated private messaging protocol (Tunnel) that leverages session-based encryption keys and a public key registry. Architecturally, Hup handles identity, content routing, and social graphs directly on-chain while utilizing IPFS for distributed media hosting and the Cidex indexer for real-time state synchronization. It is built from the ground up to support multichain state distribution and ultra-low-latency timeline delivery. What problem does it solve? Traditional social networks suffer from platform monopolies, centralized content moderation, and aggressive data tracking. Existing Web3 social primitives attempt to solve this but fail at scale; legacy EVM chains impose massive sequential bottlenecks, forcing developers to compromise on decentralization by shifting user feeds, likes, and messaging off-chain or onto centralized indexer databases due to prohibitive gas costs and slow block times. Hup solves this by moving the entire social graph and interaction matrix fully on-chain. By decoupling independent user actions, data profiles, and message streams, Hup's smart contracts avoid storage slot overlap. This non-conflicting state design directly leverages Monad’s parallel execution pipeline, ensuring that millions of concurrent interactions—posts, follows, and encrypted messaging—can occur simultaneously without sequential queue bottlenecks, delivering sub-second social feeds with rock-bottom transaction fees.
