Autonomous Operations

We are witnessing a fundamental shift from passive ledgers to autonomous, self-executing protocols.

How can permissionless systems perform autonomous operations without compromising security, privacy, or performance?

The People Registry’s implementation of Proof of Personhood on Polkadot presents an ideal case study for this transition. With its complex requirements for privacy-preserving operations, batch processing, and coordinated system maintenance, it highlights both the challenges and opportunities for autonomous blockchain operations.

Operational Challenges

From the forum discussions emerge:

  • The registry requires new members to join in batches of 5-10 people to maintain privacy guarantees. This creates natural queueing and scheduling requirements.

  • Ring rebuilding requires careful scheduling of its computationally heavy process to maintain smooth chain operations during member suspensions

  • The system requires mutation sessions where multiple operations must occur together, creating complex coordination requirements.

The Task API: A General Solution

The Task API represents a paradigm shift in how blockchains handle system operations. Instead of immediate execution, operations become scheduled tasks with:

  • Only run when specific conditions are met
  • Predictable resource consumption
  • Failed tasks don’t break the chain
  • Execution during appropriate blocks

Current Task API

While the Task API is still experimental, several implementations and discussions exist:

  1. The People Registry

  2. Safe Scheduler Discussion

    • Proposes moving scheduled operations from on_initialize hooks to tasks
    • Addresses the bricking risk of mandatory hook execution
    • Inspired the development of task-based execution models

  3. Salary Pallet Implementation

    • Demonstrates automated salary cycles for ranked collectives
    • Shows how to trigger tasks based on time intervals (block numbers)
    • Steps to reproduce

Conclusion: Autonomous Ecosystem?

Systems with resource aware operations can dynamically adjust maintenance schedules based on current network load. Cross parachain automation synchronizes coordinated operations across the entire Polkadot ecosystem.
