Watchdogs

Monitoring Role

Kolme’s planned watchdog nodes enhance network integrity by monitoring validator behavior and system operations across multichain ecosystems like Solana, Ethereum, and Near.

  • Function:
    • Observe processor outputs (blocks, failure notifications), listener confirmations, and approver authorizations to detect anomalies (e.g., censorship, invalid state hashes), as detailed in Core Chain Mechanics.
    • Validate transactions, data loads, and state transitions, ensuring compliance with protocol rules, per Triadic Security Model.
  • Scope:
    • Monitor gossip messages (e.g., transactions, blocks) for consistency and fairness, per Gossip.
    • Verify bridge contract events (e.g., deposits, withdrawals) to maintain multichain trust, per External Chain Resilience.
  • Operation:
    • Run independently, syncing via slow or fast sync to access chain state, per Node Synchronization.
    • Report discrepancies to the network or external auditors, enhancing transparency.

Detection Capabilities

Watchdogs are designed to identify and flag potential issues, ensuring robust security and reliability.

  • Processor Errors:
    • Detect invalid blocks (e.g., incorrect state hashes, unsigned transactions) by re-executing transactions, per External Data Handling.
    • Flag censorship if valid transactions are excluded from blocks, per Failed Transactions.
  • Validator Misbehavior:
    • Identify inconsistencies in listener confirmations or approver authorizations (e.g., quorum violations), per Triadic Security Model.
    • Monitor key rotation and version upgrade proposals for unauthorized actions, per Key Rotation and Version Upgrades.
  • Multichain Issues:
    • Verify bridge contract event processing to prevent fraudulent deposits or withdrawals, supporting Solana, Ethereum, Near, or new chains like Aptos, per External Chain Resilience.
    • Ensure chain migrations maintain integrity, per Node Synchronization.
  • Storage and Sync:

Reporting Mechanism

Watchdogs provide transparent reporting to maintain trust and facilitate rapid issue resolution.

  • Alerts:
    • Broadcast signed alerts via libp2p gossip for detected issues (e.g., invalid blocks, quorum failures), informing nodes and users, per Gossip.
    • Alerts are recorded on-chain for auditability, enhancing transparency, per Core Chain Mechanics.
  • User and Validator Feedback:
    • Notifications reach user interfaces via API servers, enabling corrective actions, per High Availability.
    • Validators (processor, listeners, approvers) receive alerts to address issues, per Triadic Security Model.
  • Security:

Advantages

Kolme’s watchdog system offers several benefits for developers building secure, multichain applications:

  • Enhanced Security: Detects and flags validator errors or misbehavior, ensuring trust, per Triadic Security Model.
  • Transparency: On-chain alerts and verifiable reports maintain auditability, per Core Chain Mechanics.
  • Resilience: Independent operation ensures monitoring persists during failures, supporting zero-downtime apps, per High Availability.
  • Multichain Integrity: Validates bridge events and chain migrations (e.g., Cosmos), per External Chain Resilience.
  • Proactive Monitoring: Early detection of issues like censorship or storage errors improves reliability, per Storage.
  • Scalability: Supports high-throughput apps with minimal overhead, per Node Synchronization.

These advantages make Kolme a robust platform for building high-performance, fault-tolerant decentralized applications.
