Magic Block has unveiled Ephemeral Rollups, a new real-time state update engine tailored for high-concurrency applications like on-chain gaming, social interactions, and trading. This innovative solution allows high-frequency game data to be temporarily offloaded to a high-speed environment, facilitating low-latency operations without incurring gas fees. Game state and logic remain on-chain for immutability, with updates periodically synchronized to the mainnet. The system utilizes Solana's account structure, PDAs, and account modification delegation to provide scalable, secure, and permissionless gaming experiences.
