Why North Star?

Vision

Sonic SVM is a high-performance SVM network built for gaming and consumer applications. It provides developers with an EVM-compatible, Solana-composable execution environment at a scale that Solana L1 alone cannot sustain for real-time workloads.

North Star takes this further. It is a session-layer scaling protocol built on top of Sonic SVM — enabling applications to provision dedicated, ephemeral SVM runtimes for specific high-intensity workloads: a multiplayer game match, an active trading session, a burst auction event.

The key primitive: Ephemeral Rollups (ERs). When an app opens a session via North Star, specific Sonic SVM accounts are temporarily delegated to a short-lived ER — a purpose-built SVM runtime that operates at wire speed. The ER inherits Sonic SVM's execution model and Solana composability. When the session closes, state is settled back to Sonic SVM and the ER is destroyed.

No persistent infrastructure. No bridging. No fragmentation. Just burst-speed compute, on demand, for as long as you need it.

The Performance Ceiling

Solana L1 achieves ~65,000 TPS with ~400ms block times and ~5s practical finality — state-of-the-art for a general-purpose blockchain. Sonic SVM extends this significantly with a dedicated SVM environment tuned for gaming workloads. But even with these gains, a class of applications requires throughput and latency characteristics that no shared execution environment can cost-effectively deliver:

• Real-time multiplayer games — A 60fps game with 100 players generates ~6,000 state updates/second from a single match. A platform hosting 1,000 concurrent matches needs 6M updates/s. Each match has different state, different participants, and a defined start and end — ideal for a dedicated compute context.

• High-frequency trading — Central limit orderbooks require <10ms matching latency. Even the most optimized shared SVM environment introduces latency variance from concurrent execution. A dedicated ER with a single orderbook program eliminates this entirely.

• Gasless micro-interactions — Users expect zero-friction UX. At 1M operations/day, per-operation base fees accumulate quickly. North Star's session fee model shifts cost to a single upfront deposit, enabling effectively gasless interactions within the session.

These are not limitations of Sonic SVM's design — they are the inherent economics of shared execution at scale. North Star is the protocol-level answer.

The Dedicated Compute Gap

High-performance applications share a common pattern: they need maximum compute for a bounded time window, then go quiet. A multiplayer match lasts 10 minutes. A trading session lasts hours. A flash auction lasts seconds.

Serving these workloads on a shared execution environment creates a fundamental tension:

• Contention — Multiple applications compete for block space, creating latency variance that is unacceptable for real-time use cases

• Economic inefficiency — Peak-capacity infrastructure sized for burst traffic is wasteful when idle. Applications pay for capacity they use intermittently.

• Isolation — One application's burst traffic should not degrade another's user experience

The traditional answer — dedicated off-chain servers — sacrifices verifiability, composability, and trustlessness. Users can't audit game logic. Assets can't compose with on-chain DeFi. Outcomes can be manipulated.

North Star closes this gap: verifiable, dedicated compute, on-chain, for the duration of a session. Applications get the isolation and performance of a dedicated server, with the security and composability of a Sonic SVM program.
