Caldera: From Code Auditing to Quantum Defense, Strengthening the Web3 Security Moat
In the Web3 world, security is the cornerstone of a robust ecosystem. Caldera, with the core philosophy of "full-cycle protection and multi-dimensional coverage," has built a comprehensive security barrier that spans from the technical foundation to emergency response, successfully safeguarding a total locked value (TVL) of $1 billion and becoming a benchmark in industry security practices.
The foundation of its security system is deeply rooted in the innovative application of cryptographic technology. Through BLS signature technology, Caldera ensures the security and efficiency of validator consensus, laying a solid trust foundation for distributed networks; meanwhile, ECDSA is utilized for transaction encryption verification, allowing every operation to have traceable and immutable characteristics, thereby avoiding security risks at the transaction level from the outset.
In the face of potential future threats, Caldera has initiated a forward-looking layout. It plans to complete a cryptographic upgrade by 2026, introducing post-quantum resistance technology to preemptively guard against the encryption-breaking threats posed by quantum computing, injecting long-term security into the ecosystem. Additionally, in response to user privacy protection needs, ZK-SNARKs technology is actively under development, aiming to achieve transaction verification through zero-knowledge proofs without disclosing data details, further enhancing the ecological privacy security level.
Security auditing is a key step for Caldera to validate its reliability. In June 2025, the world’s top security firm Trail of Bits conducted a comprehensive review of its smart contracts, and the results showed no critical security issues were found, fully validating the robustness at the code level. The audit scope extends to Metalayer relays, ensuring data security during cross-module transmission by rigorously verifying message integrity, eliminating the risk of tampering in intermediate links.
In terms of threat response, Caldera has launched several targeted protective measures based on precise threat models. To address the risk of centralization in sequencers, a progressive decentralization scheme is adopted to gradually distribute core node permissions, reducing the probability of single points of failure; in the face of DDoS attacks, by integrating Cloudflare protection services and limiting RPC call frequency, it provides dual defenses against traffic impacts, ensuring stable network operation.
