How the Private State Tokens API helps protect user privacy

The Private State Tokens API incorporates several key privacy protections:

• Data minimization: Limiting the number of keys per issuer to six reduces the amount of information stored in tokens, reducing the risk of re-identification. 
• Transparency: Required registration process with clear disclosures about the issuers’ stated purposes for using Private State Tokens provides additional user transparency. 
• User privacy: Limits on token issuance and redemption help safeguard user privacy by limiting the ability to combine Private State Tokens signals to re-identify a user.
• Security: Cryptographic signing ensures the integrity and authenticity of tokens, preventing fraud and unauthorized use.
