Your Fingerprint, Privacy and Accountable Wallets

Wallet Governance BGIN Block #11

Key Takeaways:

• Biometric wallets introduce new security paradigms with privacy implications.

• Accountable wallets offer a path to compliance while preserving user privacy.

• The industry faces challenges balancing security, convenience, and regulatory compliance.

• Privacy pools and accountable wallets could create synergistic benefits.

• Emerging governance models need standardization and clear incentive structures.

Build to be Biometric

BGIN Block #11 explored innovative approaches to wallet security, with biometric solutions taking center stage. Two key categories emerged:

Biometric-Locked Wallets

• Uses biometrics for key activation

• Stores encrypted keys on device

• Combines security with convenience

Biometric-Bound Wallets

• Derives keys from biometric data

• No key storage required

• Stronger user-key binding

One expert noted: "The best thing about biometrics is it works for you and only you. The problem with biometrics is it represents you and only you."

The Accountable Wallet Vision

A concept the IKP Working group has been developing, Accountable Wallets, was introduced at the session:

1. Core Principles

2. Key Features

   • Association sets

   • Privacy pools integration

   • Compliance verification

   • Reputation management

Privacy vs. Compliance
