Core Signature Verification Standard

Abstract​

CIP-712, the Core Signature Verification Standard, defines a standard for securely encoding and verifying structured data signatures in Core Blockchain-based applications. Core Signature Verification Standard enhances security and usability by allowing users to sign structured data, making it resistant to replay attacks and improving user experience.

Motivation​

The motivation behind CIP-712 is to provide a standardized method for encoding and verifying structured data signatures in Core Blockchain-based systems. This standardization simplifies the process of signing and verifying data, making it more secure and user-friendly.

We have aliased EIP712 to CIP712 and created this CIP.

Specification​

Core Signature Verification Standard defines the following key components and processes:

Typed Data​

Core Signature Verification Standard introduces a structured data schema called "Typed Data," which includes a list of data types and their field names. This schema provides a clear definition of the data being signed.

Encoding​

The data specified in the Typed Data schema is encoded into a binary format before signing. This encoding ensures consistency in how data is presented to users for signature.

Hashing​

Core Signature Verification Standard defines a specific hashing mechanism for hashing the binary data. This ensures that the data hash remains consistent across different implementations.

Signatures​

Users sign the hashed data, creating a unique signature that represents their approval of the structured data.

Verification​

Smart contracts or applications can then verify the signature against the original Typed Data and public keys to ensure the authenticity of the data.

Usage​

Core Signature Verification Standard can be utilized in various Core Blockchain-based applications, including decentralized finance (DeFi), governance systems, and more. Users can sign structured data, and smart contracts can validate these signatures to enable secure interactions.

Backward Compatibility​

Core Signature Verification Standard is designed to be backward-compatible with existing Core Blockchain standards, ensuring seamless integration into the Core Blockchain ecosystem.

Security Considerations​

Security audits and reviews are crucial for any implementation of Core Signature Verification Standard to identify potential vulnerabilities and ensure the robustness of the signature verification process.

Conclusion​

CIP-712 provides a standardized approach to structured data signature verification in Core Blockchain-based applications. Its adoption can enhance security and usability in a wide range of decentralized systems.
