Crypto KYC: Understanding KYC in Blockchain

Traditional KYC Systems

A person's identity can be easily verified through government-issued documents such as passports, birth certificates, social security cards, or driver's licenses. However, this method is only effective in face-to-face interactions. Remote identity verification is prone to fraud, as individuals can bypass checks using original or copied documents.

To mitigate these risks, "Know Your Customer" (KYC) procedures were introduced. While KYC enhances identity verification reliability, it often results in inefficient, lengthy, and opaque processes involving extensive personal and business data.

Key Components of Traditional KYC:

1. Identity Verification (IDV):

   • Verification via physical or digital documents.
   • Often involves superficial checks or database cross-referencing (e.g., credit history databases).

2. Customer Identification Program (CIP):

   • Checks against national and corporate blacklists.
   • No universal standards; organizations tailor checks based on jurisdiction and resources.

3. Video Identification:

   • Conducted via platforms like Skype, Viber, or Google Hangouts.

Drawbacks of Traditional KYC:

• Redundancy: Each entity (e.g., banks) independently verifies users, leading to duplicated efforts.
• Cost and Time: Repeated checks incur significant expenses and delays.
• Security Risks: Sensitive data transfers increase exposure to interception or hacking.

Blockchain-Based KYC Systems

Distributed Ledger Technology (DLT) and blockchain enable centralized, cryptographically secure databases for user identity verification without third-party intermediaries. Users complete KYC once and reuse verified credentials across platforms.

How It Works:

1. A user submits KYC documents to a participating entity (e.g., a bank).
2. The entity verifies and approves the KYC.
3. User data is stored on a blockchain accessible by other authorized entities.
4. Subsequent verifications are streamlined—entities query the blockchain for confirmation.
5. Users retain data ownership and control access via private keys.

Real-World Example:
IBM, Deutsche Bank, HSBC, MUFG, and Cargill collaborated on a decentralized KYC platform for secure data sharing and verification.
