To address state synchronization delays exceeding 2 seconds in the MUD full-stack game engine, implement these solutions: First, adopt optimistic rendering to pre-render client-side actions before blockchain confirmation, reducing perceived lag. Second, optimize state updates by sending only delta changes (e.g., position, health) instead of full states, minimizing bandwidth usage. Third, use a synchronized execution model, sharing non-deterministic inputs like player actions to ensure consistency across clients. Fourth, leverage MUD’s SOLECS and RECS libraries for efficient on-chain and client-side state mirroring. Finally, reduce tick rates for less frequent updates in high-latency scenarios, balancing responsiveness and accuracy. These techniques, inspired by Web2 lockstep and event-driven models, mitigate blockchain-induced delays while maintaining game fluidity and fairness.
