StarkEx vs StarkNet: Throughput Scaling

Guaranteed, dedicated capacity: Each application (dYdX, Sorare) runs on its own separate, configurable StarkEx instance. This provides predictable 9,000+ TPS per app and sub-second finality, insulated from network congestion. This matters for centralized-exchange-grade DeFi and high-frequency NFT marketplaces requiring SLA-backed performance.

Optimized, fixed operational costs: As a SaaS framework, costs are predictable and scaled with the specific app's volume. No competition for block space or volatile L1 gas fees for proofs. This matters for enterprise applications with strict P&L requirements and projects needing to model transaction costs years in advance.

Composable, unified liquidity: All dApps (JediSwap, Ekubo) and assets (STRK, ETH) exist on a single, permissionless L2. Enables native composability like cross-protocol flash loans and shared state. This matters for DeFi ecosystems and innovative dApps that rely on interoperability and cannot exist in an isolated silo.

Anyone can deploy: A general-purpose, Turing-complete ZK-Rollup where developers can deploy any Cairo smart contract without approval. Fosters a permissionless innovation layer similar to Ethereum. This matters for protocols wanting full sovereignty, experimental dApps, and long-tail use cases not served by app-specific stacks.

Trade-off: Operator Control: The application operator (e.g., dYdX) acts as the sole sequencer, providing efficiency but introducing a single point of trust for transaction ordering and liveness. This matters for teams prioritizing maximum performance and customization over decentralized sequencing.

Trade-off: Variable Performance: Throughput is shared across the entire network (~100-200 TPS network-wide). During high demand, users and dApps compete for block space, potentially leading to higher fees and latency. This matters for applications that cannot tolerate performance variability from network-wide activity spikes.

Application-Specific Optimization: Each deployment (e.g., dYdX, Immutable X, Sorare) is a dedicated, isolated instance. This allows for custom data models and transaction logic, enabling 9,000+ TPS in production for specific applications like orderbook trading.

This matters for established enterprises and protocols that need guaranteed, high-frequency performance and are willing to manage a dedicated validator.

Deterministic Fee Structure: As a SaaS model, costs are predictable and not subject to network congestion from other dApps. Batch proofs amortize costs across thousands of transactions, leading to sub-cent fees for users.

This matters for consumer-facing applications (NFT marketplaces, gaming) where user experience and predictable micro-transactions are critical.

Composable Ecosystem: All dApps (JediSwap, Ekubo, Nostra) share liquidity, security, and state on a single L2. This enables native composability, where a swap on one DEX can directly trigger a lending action on another protocol within the same block.

This matters for DeFi innovators and developers building interconnected products that rely on a rich, permissionless ecosystem of smart contracts.

Open Deployment: Any developer can deploy a Cairo smart contract without permission. This fosters rapid experimentation and a broader developer base, evidenced by 1,000+ live contracts.

This matters for startups, hackathon projects, and protocols that prioritize open access, community-driven growth, and avoiding vendor lock-in.

Application Silos: Each StarkEx instance is an isolated environment. Assets and liquidity are not natively interoperable with other StarkEx apps or the broader StarkNet without complex bridging.

This is a trade-off for protocols that choose ultimate performance and control over ecosystem integration. It requires building your own liquidity from scratch.

Contention for Resources: Throughput is shared across the network. During peak demand (e.g., a major NFT mint), proof generation can bottleneck, increasing latency and causing fee spikes, though still far below L1.

This is a trade-off for the benefits of a shared L2. Performance is "good enough" for most dApps but lacks the ironclad guarantees of a dedicated stack.

Dedicated Validity Proofs: Each application (dYdX, Sorare) runs its own sequencer and generates proofs for its specific state transitions. This allows for 9,000+ TPS (dYdX v3) and predictable, app-controlled fee models. Ideal for exchanges and games needing isolated, max-performance environments.

Managed Service Model: StarkEx operators (like StarkWare) provide formal Service Level Agreements for uptime, proof generation latency, and support. This guarantees >99.9% availability and dedicated engineering resources, crucial for financial institutions like ImmutableX and Sorare with millions of users.

Composable Ecosystem: All dApps (JediSwap, Ekubo) share a single state, enabling native composability and liquidity aggregation. TVL is pooled network-wide (~$1.3B), not siloed per app. This is critical for DeFi protocols requiring seamless integration, like lending/borrowing with Nostra.

Anybody Can Deploy: Developers deploy smart contracts directly to the public L2 without vendor approval, using Cairo. This fosters a large, open ecosystem with 500+ live contracts and rapid experimentation (e.g., ERC-721, ERC-1155, ERC-20). The trade-off is competing for block space in a shared environment.

App-Chain Silos: dApps on different StarkEx instances (e.g., a game on Immutable and an NFT on Sorare) cannot interact without complex, trust-minimized bridges. This fragments liquidity and limits complex DeFi legos. Choose StarkEx only if your app operates as a closed economy.

Contested Block Space: Throughput is shared, leading to variable TPS (45-100+ TPS network-wide) and potential fee spikes during congestion (e.g., major NFT mints). While Cairo VM optimizations improve efficiency, you cannot reserve dedicated capacity like with StarkEx.
