🔐 What is Staking?

Staking in Arch Network is fundamentally different from traditional Proof of Stake systems. Instead of using staking for consensus, Arch Network uses staked validators to participate in the ROAST protocol for secure Bitcoin transaction signing.

📊 Staking Economics

🔄 ROAST Protocol Integration

The ROAST (Robust Asynchronous Schnorr Threshold) protocol enables validators to collectively sign Bitcoin transactions:

    participant C as Client
    participant L as Leader
    participant V as Validators
    participant B as Bitcoin Network
    
    C->>L: 1. Submit Transaction
    L->>V: 2. Distribute to Validators
    V->>V: 3. Execute in Arch VM
    V->>L: 4. Sign Results
    L->>B: 5. Submit to Bitcoin
