Why Signatures Matter

Digital signatures ensure authentication, data integrity, and security in blockchain transactions. They verify the sender’s identity, prevent data tampering, and provide non-repudiation, ensuring accountability.

​
How to Generate a Signature

  • Private Key Usage: A unique private key is used (in beliquid’s context, it is the private key of the sessionKey which is passed during authentication) to create a signature.
  • EIP-712 Standard: Signatures follow the EIP-712 standard for structured data.
  • Message Formatting: Data is structured into a typed format, ensuring consistency and readability.
  • Hash Computation: The structured data is converted into a unique hash.
  • Signature Creation: The private key signs the hash, generating a verifiable signature.
  • Verification: The recipient can use the signer’s public address to confirm authenticity.

​
Key Benefits

  • Security: Protects against unauthorized changes.
  • Efficiency: Enables fast and reliable verification.
  • Compliance: Uses industry standards for interoperability.
To generate your own signatures, refer to the EIP-712 specification for implementation details and best practices. By following this structured approach, applications ensure trust and transparency in digital interactions.
