State Channels Systemic Security Considerations and Solutions
summary
Proposes concrete state channel primitives: require a single-enforcer rule so only one party can publish a given state, use fidelity bonds (refundable if attestations are correct) and Truebit-style bonded attestation to push heavy computation on chain only when disputed. Shows a routed example (Alice→Bob→Carol→Dave) where Carol posts a bond, waits a 3–4 day window, loses the bond if on-chain recomputation proves her attestation false, and argues modular UTXO-like contracts and relative timestamps minimize on-chain cost and systemic risk.
