Lektra SolarCompute

Lektra Compute is a prototype marketplace for solar-powered AI inference. Users submit AI jobs that run on distributed GPU nodes powered by renewable energy.

The compute layer uses Ray clusters orchestrated on Kubernetes, while Arbitrum smart contracts handle escrow and settlement.

When a job completes, the result hash is anchored on-chain and payment is automatically released to the compute provider.

Architecture:

User → Arbitrum Smart Contract (escrow)

→ Lektra Ray GPU node (AI inference)

→ Result hash submitted on-chain

→ Contract releases payment

Day 1

• Designed architecture integrating Ray GPU clusters with Arbitrum smart contracts

• Created GitHub repo and project structure

• Implemented escrow smart contract prototype

Day 2

• Connected compute job lifecycle to blockchain settlement

• Built relayer/sidecar service to submit result hashes on-chain

• Integrated Ray job execution pipeline

Day 3

• Demonstrated end-to-end flow:

User submits AI job → compute runs on GPU node → result hash recorded on Arbitrum → payment released
