Hello everyone,

I’d like to share an idea for discussion and see whether it would be feasible to implement. I’d especially like to hear the opinions of people who are more deeply involved in the AI space.

I believe this could create an additional revenue stream for Polkadot. One advantage is that there are already open-source projects, such as Phala and Bittensor, with similar approaches that we could potentially leverage.

1. Overview

The idea is to build a dedicated Polkadot system parachain that coordinates a distributed network of compute providers organized into specialized compute pools. Initially, the network would consist of dedicated CPU and GPU pools, allowing workloads to be routed to the most appropriate hardware automatically.

Anyone can join the appropriate pool by staking DOT and proving they possess real computational resources. The protocol assigns workloads based on the job’s requirements and verifies execution off-chain, providing trust-minimized guarantees on-chain through optimistic fraud proofs and strong cryptoeconomic incentives.

2. Core Features

  • Native Polkadot Architecture – Built as a system parachain without requiring changes to the Relay Chain.
  • Dedicated Compute Pools – Independent CPU and GPU pools optimize scheduling, pricing, and resource allocation while enabling providers to specialize in the hardware they operate.
  • Open Compute Marketplace – Anyone can join a compute pool by staking DOT and contributing CPU, GPU, or future specialized hardware resources.
  • Staking and Slashing – Compute providers stake collateral that can be slashed for dishonest behavior, failed disputes, or prolonged downtime.
  • Optimistic Verifiable Execution – Jobs are assumed correct upon submission. Verification relies on optimistic fraud proofs triggered during a challenge window.
  • Automatic Workload Routing – Jobs are automatically assigned to the appropriate compute pool based on their hardware requirements.
  • On-Demand Compute – Users can submit one-off computation jobs without selecting infrastructure manually.
  • Continuous Execution – Users can deploy long-running services and applications.
  • Shared Security – Coordination, dispute resolution, and the staking ledger leverage Polkadot’s shared security and economic consensus.

3. Vision

Polkadot Compute aims to add decentralized, trust-minimized compute as a native capability of the Polkadot ecosystem. By coordinating specialized CPU and GPU compute pools, it enables applications to access verifiable computation without relying on centralized infrastructure, creating new opportunities for developers, infrastructure providers, and the network itself.

In one sentence

Polkadot Compute is a decentralized cloud and verifiable execution network built as a Polkadot system parachain, coordinating specialized CPU and GPU compute pools that automatically execute on-demand and continuous workloads, secured by staking, redundancy, and optimistic fraud proofs.

Alternative Direction: AI-Focused Compute Network

Another potential direction under consideration is to focus the network specifically on AI workloads by creating dedicated AI compute pools with pre-deployed open-source models.

Instead of providing only raw CPU/GPU resources, the network could offer ready-to-use AI services where providers operate specialized pools running different open-source models (LLMs, image generation models, speech models, embedding models, and other AI workloads).

Users could access these models through a decentralized API layer, while the network handles workload routing, resource allocation, model availability, and economic incentives for providers.

This approach could position Polkadot Compute as a decentralized AI infrastructure layer, combining distributed GPU resources, open-source AI models, and cryptoeconomic security through staking, reputation, and verification mechanisms.
