For all the excitement around Verifiable Credentials, there is a rather mundane problem hiding underneath the cryptography:

Read article: SD-JWT VC vs. BBS-2023: Why These Aren’t Really the Things You’re ComparingIf you’ve spent any time reading about modern cryptography — especially BBS Signatures, attribute-based credentials, or identity-based encryption — you’ve probably encountered the phrase bilinear pairing.
Read article: Bilinear Pairings: Modern Privacy-Preserving CryptographySelective Disclosure is fundamentally a mathematical concept. The protocols (SD-JWT VC, BBS-2023, AnonCreds, Idemix, U-Prove, etc.) are really just engineering built on top of several branches of mathematics.
Read article: Selective Disclosure: The MathFor decades, digital identity has operated on a remarkably inefficient principle, “If someone asks for one piece of information, give them everything.”
Read article: Selective Disclosure: Finally, an Identity System That Knows When to Stop TalkingWebAuthn is actually the tip of a much larger iceberg. Like the SD-JWT VC spec, it is built upon several W3C, FIDO Alliance, and IETF specifications. Together, these define a complete passwordless authentication ecosystem.
