1. Executive Summary

The Utility-Protocol Contracts platform provides a decentralized utility streaming protocol with comprehensive security measures including:

Tamper-proof nonce synchronization for IoT device liveness verification
Time-of-Use tariff pricing with 24-hour schedules
Automated ghost stream cleanup to maintain ledger efficiency
Multi-sig governance for critical operations
Emergency response capabilities for rapid threat mitigation

Security Improvements Implemented (Issues #260-263)

Issue	Feature	Security Benefit
#260	Hardware Nonce Sync	Eliminates replay attacks against device liveness monitoring
#261	Utility-Tariff Oracle	Enables complex pricing models with seamless rate transitions
#262	Ghost Stream Sweeper	Reduces ledger footprint while maintaining historical integrity
#263	Documentation Sweep	Enterprise-grade documentation for audit readiness

2. Security Architecture Overview

2.1 Core Security Components

Implementation: Strict incrementing u64 nonce per device MAC address
Security Features:
- +1 to +5 nonce window for network jitter tolerance
- Multi-sig nonce reset for compromised devices
- Automatic suspicious device marking
- Comprehensive audit trail

Tariff Oracle System

Purpose: Manage Time-of-Use pricing schedules
Implementation: 24-hour pricing windows with grid administrator control
Security Features:
- 24-hour notice period for tariff changes
- Cryptographic signature verification
- Temporary storage optimization
- Seamless rate interpolation

Ghost Stream Management

Purpose: Maintain ledger efficiency by pruning abandoned streams
Implementation: 90-day zero balance threshold with archive preservation
Security Features:
- Cryptographic archive hashes for integrity

3. Roles and Responsibilities

Role	On-chain Key / Storage	Duty	New Security Features

Compliance Officer	`DataKey::ComplianceOfficer`	Trigger and release legal freezes	Ghost stream emergency cleanup
Finance Wallet (×3–5)	`MultiSigConfig.finance_wallets`	Propose, approve, revoke, and cancel large withdrawal requests; quorum = `required_signatures`	Ghost stream gas bounty approval
Oracle / Resolver	`DataKey::Oracle`	Resolve service challenges (`resolve_challenge`)	Tariff oracle signing
Grid Administrator	`DataKey::TariffOracleAdmin`	Manage tariff schedules	New - Issue #261
Nonce Reset Authority	`DataKey::AuthorizedNonceResetters`	Reset compromised device nonces	New - Issue #260

Multi-sig quorum rule

Any action requiring required_signatures approvals must be coordinated off-chain first (Signal group, emergency Telegram, or PagerDuty). Confirm quorum is available before submitting the first on-chain transaction. The contract enforces the threshold — a request with insufficient approvals will revert on execution.

Key storage locations (for incident verification)

DataKey::CurrentAdmin          → DAO Admin address
DataKey::ComplianceOfficer     → Compliance Officer address
DataKey::Oracle                → Oracle/Resolver address
DataKey::TariffOracleAdmin     → Grid Administrator address (New)
DataKey::MultiSigConfig(addr)  → Per-provider multi-sig config
DataKey::VetoDeadline          → Active upgrade veto deadline (Unix timestamp)
DataKey::ProposedUpgrade       → Active UpgradeProposal struct
DataKey::DeviceNonce(mac)      → Device nonce state (New)
DataKey::CurrentTariffSchedule → Active tariff schedule (New)
DataKey::StreamArchive(id)     → Pruned stream archive (New)

4. Pre-Incident Checklist

export PROVIDER_KEY=<provider-secret-key-or-identity-alias>
export FINANCE_KEY=<finance-wallet-secret-key-or-identity-alias>
export GRID_ADMIN_KEY=<grid-admin-secret-key-or-identity-alias>

# 5. Verify the contract is responsive
stellar contract invoke \
  --id $CONTRACT \
  --network testnet \
  -- \
  get_count

# 6. Check the current meter count and note it
export METER_COUNT=$(stellar contract invoke \
  --id $CONTRACT \
  --network testnet \
  -- \
  get_count)
echo "Total meters: $METER_COUNT"

# 7. Verify your key matches the expected admin address
