Attestor Network

Guardians of iBTC’s Integrity

The iBTC Attestor Network is a decentralized coalition of independent node operators ensuring every iBTC token is 1:1 backed by BTC on Bitcoin Layer 1. Comprising institutional-grade operators, DeFi participants, and security researchers, attestors validate transactions, co-sign movements, and maintain transparency with Chainlink PoR.

What Attestors Do

  • Verify Deposits: Monitor Bitcoin blockchain for vault deposits, ensuring compliance with protocol standards.

  • Co-Sign Transactions: Use FROST to co-sign BTC movements, requiring a quorum (e.g., 10-of-15) to approve.

  • Ensure Backing: Confirm 1:1 BTC backing via Chainlink PoR audits, providing real-time transparency.

  • Facilitate Redemptions: Validate iBTC burns and authorize BTC releases, ensuring trust-minimized withdrawals.

Who Are the Attestors?

  • Node Operators: High-uptime infrastructure providers with proven blockchain expertise.

  • DeFi Participants: Entities securing decentralized networks, enhancing iBTC’s ecosystem.

  • Security Experts: Independent researchers contributing to protocol hardening.

Security Measures

  • FROST Signatures: Reduces fraud risk with threshold-based co-signing.

  • Global Distribution: Nodes operate redundantly with hardware security modules (HSMs) for key protection.

  • Continuous Monitoring: Actively tracks on-chain activity to prevent breaches.

  • Audits: Regular infrastructure audits by independent firms ensure compliance.
