Comprehensive technical specifications of Deterministic State Channels

Contents

1. Introduction

Deterministic State Channels (DSC) is a high-throughput Layer 2 scaling solution that provides guaranteed settlement times for blockchain transactions while maintaining security and decentralization. Unlike traditional state channels, DSC offers mathematically guaranteed finality windows, making it suitable for time-sensitive applications requiring definitive settlement assurances.

Key Benefits

  • Deterministic settlement guarantees
  • High throughput (10,000+ TPS)
  • Full security inherited from base layer
  • Tunable guarantees for different use cases

Example State Channel Usage


// Creating a channel with 1-second guarantee
const channel = await DSC.createChannel({
  participants: [alice, bob],
  deposits: [100, 100],
  settlementGuarantee: 1000, // 1 second
  validators: 5
});

// Update state off-chain
const result = await channel.updateState(newState);
console.log(`Guaranteed settlement by: 
${result.guaranteedSettlementTime}`);

Settlement

The Deterministic State Channel protocol defines a comprehensive lifecycle with mathematically guaranteed settlement windows at each stage. The following details the specification for each component:

1Channel Creation Protocol

Creates a new state channel with temporal guarantees based on validator committee selection and time-locked bonds.

Function Signature:
function createChannel( address[] participants, uint256[] initialDeposits, uint256 settlementTimeWindow, uint8 validatorCount, uint256 guaranteeAmount ) → bytes32 channelId
Parameters:
  • participants: Array of participant addresses
  • initialDeposits: Initial stake amounts
  • settlementTimeWindow: Guaranteed resolution time (ms)
  • validatorCount: Committee size (3-11 validators)
  • guaranteeAmount: Economic security bond
Security Properties:
  • Validator selection via VRF (Verifiable Random Function)
  • Time-locked security deposits
  • Participant signature verification
  • On-chain state root registration

2State Update Protocol

Facilitates off-chain state transitions with validator consensus and temporal cryptographic attestations.

Protocol Flow:
1. Participant proposes state update: {state, nonce, signatures}2. Validator committee validates state transition 3. Temporal proof generation: TP = Sign(H(state | nonce | timestamp), vKey)4. Threshold signatures from ⅔ committee 5. Return: {newState, guaranteedSettlementTime, temporalProof}
Temporal Guarantees:
  • Validator committee consensus timestamps
  • Multi-signature temporal attestations
  • Byzantine fault tolerance (up to f=⌊(n-1)/3⌋)
  • Cryptographic settlement proofs
Performance Metrics:
  • Update latency: 50-200ms average
  • Throughput: 10,000+ TPS per channel
  • Validator confirmation: ≥ ⅔ of committee
  • Settlement guarantee: user-defined (min 500ms)

3Dispute Resolution Protocol

Handles conflicts with deterministic resolution timeframes and validator accountability.

Function Signature:
function initiateDispute( bytes32 channelId, bytes32 stateRoot, uint256 nonce, bytes temporalProof, bytes[] signatures ) → uint256 resolutionTimestamp
Resolution Mechanism:
  • Challenge-response window: T₀ + W (user-defined)
  • Validator slashing for timeout violations
  • Automatic resolution if undisputed
  • Temporal proof verification on-chain
Security Guarantees:
  • Mathematically bounded resolution time
  • Economic penalties for validator misbehavior
  • Game-theoretic incentive alignment
  • Liveness protection via timeout fallbacks

4Settlement Finalization Protocol

Finalizes the latest valid state on-chain with asset distribution according to the final state.

Function Signature:
function settleChannel( bytes32 channelId, bytes32 finalStateRoot, uint256 nonce, bytes[] signatures, bytes temporalProof, address[] payouts, uint256[] amounts ) → bool success
Settlement Logic:
  • Highest nonce state verification
  • Temporal proof validation
  • Asset distribution based on final state
  • Validator bond release/slashing
Finality Guarantees:
  • Deterministic settlement time: T₀ + W
  • Atomic state execution
  • Economic finality via bonds
  • Settlement receipt generation

3.2 Optimistic Execution Model

Chronos DSC implements an optimistic execution model that assumes honest behavior by default but provides strong guarantees through a combination of cryptographic techniques and economic incentives:

Temporal Cryptography

  • Time-locked commitments
  • Threshold signature schemes
  • Verifiable delay functions (VDFs)
  • Cryptographic timestamping

Economic Guarantees

  • Validator bonding mechanisms
  • Progressive slashing conditions
  • Reward-penalty equilibrium
  • External insurance pools
