Decentralized Arbitration Protocol

What is it?

The Decentralized Arbitration Protocol is a trustless guarantee system for Bitcoin transactions. It enables secure Bitcoin transaction execution through a decentralized network of arbiters who stake assets as collateral for their services. The protocol uses zero-knowledge proofs for automated dispute resolution, ensuring fair and transparent handling of transaction conflicts.

Why use it?

• Trustless Bitcoin Transactions: Execute Bitcoin transactions safely without trusting counterparties
• Automated Guarantees: Get immediate compensation if transactions go wrong
• Zero Trust Required: All enforcement is automated through smart contracts and zero-knowledge proofs
• DApp Integration: Easy to integrate with any application needing secure Bitcoin transaction handling
• Decentralized Security: Network of independent arbiters with staked assets

How it works

1. DApp Registration

   • DApps apply to use the protocol
   • Application review process ensures quality
   • Once approved, DApp can request arbiters for transactions

2. Transaction Flow

   • DApp requests arbiter guarantee for a transaction
   • If transaction completes normally, arbiter isn't involved
   • In disputes, arbiter helps by signing Bitcoin transactions
   • All actions are backed by arbiter's staked assets

3. Dispute Resolution

   • If arbiter misbehaves (wrong signature or no response)
   • Victim submits transaction to ZK service for proof
   • Proof submitted to protocol for automated verification
   • Valid claims receive immediate compensation from arbiter's stake

Technical Architecture
