Celestia's next upgrade, Hibiscus (V7), goes live mid-March. Hibiscus introduces 2 features that expand cross-chain interoperability for networks on Celestia: - single-signature cross-chain transfers - cryptographic proof-based message verification Here's how it works:

Forwarding Module: Moving tokens across chains usually meant signing multiple transactions. With V7, a single signature routes assets through Celestia across chains via Hyperlane. The destination is cryptographically committed upfront and permissionless relayers handle the rest.

ZK Interchain Security Module: Previously, cross-chain message verification relied on trusted multisig validators. ZK ISM replaces that with Groth16 cryptographic proofs, giving high-value applications a trust-minimised alternative for verifying messages across chains.
