Additive Security Model

Hashi’s security model is based on additive security, where the more oracles involved, the greater the level of protection. This allows developers to dynamically scale the security of their cross-chain interactions by increasing the number of oracles participating in validation.

  • How Additive Security Works Rather than relying on a single source of truth, Hashi collects validation results from multiple oracles. As more oracles participate in validating block headers and messages, the security of the system increases. This model ensures that even if one or several oracles are compromised, the overall integrity of the system is maintained.

  • Dynamic Security Developers can adjust the security threshold based on their specific needs. For routine transactions, fewer oracles may be sufficient, but for high-stakes interactions, the number of validating oracles can be increased to ensure maximum security.
