Web3 social apps are evolving fast, combining the familiarity of Web2 with the openness and decentralization of Web3. Cartesi appchains empower builders to create rich, complex social experiences, including collaborative content, AI-driven interactions, and gamified communities, while keeping everything secure and verifiable on-chain. Projects like Scribbl, where AI judges doodles in a decentralized and transparent way, show how Cartesi opens new possibilities for social apps and creative ecosystems.

Recent advances in Non-Interactive (NI) ZK Fraud Proofs, like Kailua and OP Succinct Lite, promise faster withdrawals and lower costs for optimistic rollups. We rigorously steel-manned NI designs against a strong threat model and compared them to Interactive Fraud Proofs (like Dave) and ZK Validity Proofs. Our analysis finds that current NI systems are vulnerable to Sybil attacks, coordination failures, and resource exhaustion, preventing true 1-of-N liveness and undermining decentralization. While NI may hold promise, they do not currently deliver the “best of both worlds,” and Interactive Fraud Proofs remain more resilient and cost-effective under adversarial conditions.

Appchains offer customizable, application-specific blockchains that solve high fees, slow transactions, and UX issues on shared networks like Ethereum. With Cartesi Rollups, developers can quickly deploy appchains anchored to Ethereum, benefiting from low costs, flexible governance, and robust fraud-proof security. While withdrawal delays exist, many DeFi applications, such as staking, yield farming, and reputation-based lending, naturally align with longer timelines, making optimistic rollups a practical and secure choice for building scalable, feature-rich apps.
