Could Cryptography Make Social Media Identity Theft a Thing of the Past?

Discord's recent data breach, involving compromised usernames, emails, and government IDs, underscores systemic vulnerabilities in centralized identity verification. The incident occurred when an unauthorized actor accessed a third-party customer service provider’s systems, exposing sensitive user data.

Industry experts argue for cryptographic solutions. Varun Kabra of Concordium highlights zero-knowledge proofs (ZKPs) as a paradigm shift—allowing platforms to verify attributes like age without storing raw documents. "Users retain encrypted credentials locally, while certified providers manage compliance copies," he notes. Such systems could have prevented Discord’s exposure of passport and driver’s license scans.

Arthur Firstov of Mercuryo echoes this sentiment, framing the breach as a catalyst for decentralized identity adoption. The conversation now pivots to blockchain-based alternatives that prioritize user sovereignty over centralized data hoarding.
