What’s cooking on @SuiNetwork? Protocol-level cryptography for ZK, offline, and PQ-native execution. There's a lot to unpack, let's take a look 👇

@SuiNetwork Sui is developing a set of cryptographic primitives that target resilience, privacy, and composability. Not consensus tweaks, but protocol-level mechanisms for deterministic off-chain execution, programmable privacy, and post-quantum security.

@SuiNetwork ZK Tunnels generalize state channels. One tx opens the tunnel. Interaction proceeds off-chain, ending with a zero-knowledge proof of state. No latency/gas during execution. Useful for P2P games, agent systems, low-connectivity environments.

@SuiNetwork These tunnels are stateless, application-agnostic, and support selective disclosure. Can run over Bluetooth or local mesh—offline-compatible. Closing the tunnel triggers proof verification on-chain.

@SuiNetwork Time Capsules: Encrypted payloads with programmable reveal logic. Not timelocks—these integrate with ZK circuits. Enables delayed access based on timestamps or events, e.g. sealed-bid auctions, wills, MEV-resistant txs.

@SuiNetwork Offline Transactions: Sui compresses tx intent into symbolic templates. Enables users to sign and transmit txs via SMS, radio, audio. Validated asynchronously. Functional in disconnected contexts (disasters, embedded systems).

@SuiNetwork Verifiable AI: On-chain randomness seeds agent execution. Inputs/outputs are hashed and bound to ZKPs. Agents operate in isolated ZK tunnels, coordinating with deterministic guarantees. Relevant for auditable AI applications.

@SuiNetwork PQ Readiness: Sui is migrating to lattice/multivariate sig schemes. The challenge is zk circuit efficiency under large PQ key sizes. Signature aggregation and circuit optimisations are in progress. Target: post-2035 security baseline.

@SuiNetwork Cross-Chain Identity (SUILINK): Signature verification across chains (e.g. Ethereum, Solana) without bridges or wrapped assets. Enables native account interoperability—core for credential migration, cross-chain rewards, identity federation.

@SuiNetwork Recovery & Solvency: On-chain recovery logic via reactive key loss protection. Inactivity triggers ZK-based recovery agents. Solvency proofs use zkSNARKs to verify reserve/liability ratios without exposing user data.

@SuiNetwork Sui’s approach shifts focus to protocol-native guarantees: deterministic execution, offline viability, ZK-enforced privacy, and cryptographic identity. Not marketing—just different assumptions baked into protocol primitives.
