We're excited to announce Polyhedra Network's strategic partnership with Caldera, bringing zkBridge technology to Caldera rollups. This integration empowers developers to offer secure, efficient cross-chain interoperability for L1 and L2 networks.
The Cross-Chain Challenge: Security vs. Efficiency
Current bridging solutions suffer from critical limitations:
- Exorbitant Costs:
Traditional Ethereum bridging requires verifying block headers across 20,000+ validators, costing ~64M gas ($6,000 per transaction). - Security Risks:
Committee-based bridges introduce vulnerabilities, with $1.6B lost to bridge exploits in 2022 alone (e.g., Wormhole, Ronin).
How zkBridge Revolutionizes Interoperability
zkBridge eliminates these tradeoffs through:
✔ Zero-trust architecture via ZK-proof cryptography
✔ 90% cost reduction through recursive proof schemes
✔ Ethereum consensus verification (~$40B staked ETH secured)
✔ 8-second proof generation (matches Ethereum block time)
Why Caldera Rollups Benefit from zkBridge
This partnership enables:
- App-specific rollups with native interoperability
- Enhanced security via EigenLayer ETH restaking
- Modular efficiency without compromising decentralization
"Polyhedra's zkBridge aligns perfectly with Caldera's vision for performant, secure AppRollups." — Caldera Team

FAQ: zkBridge on Caldera Rollups
Q: How does zkBridge prevent front-running attacks?
A: Our ZK-proof system cryptographically validates transactions without exposing sensitive data.
Q: What chains are currently supported?
A: zkBridge supports Ethereum, L2s, and Caldera AppRollups with more networks coming soon.
Q: How does this compare to optimistic rollup bridges?
A: zkBridge provides instant finality versus 7-day challenge periods in optimistic solutions.
Q: Can existing Caldera chains upgrade to zkBridge?
A: Yes! Contact both teams for migration support.
Q: What's the gas cost for zkBridge verification?
A: Approximately 1/10th of traditional bridge costs.
