⚡ Bounty: Decentralized GPU Render Protocol — RTC Payment Layer (100 RTC)

[Scottcjn]

⚡ Decentralized GPU Render Protocol

RustChain payment layer for the decentralized GPU render marketplace (see BoTTube #39).

Overview

GPU providers attest their hardware via RustChain → Accept render/voice/inference jobs → Get paid in RTC

Requirements

GPU Node Attestation

• Extend miner attestation to include GPU specs
• Report: GPU model, VRAM, CUDA/ROCm version, benchmark score
• Hardware fingerprint for GPUs (prevent spoofing)
• New device_arch types: nvidia_gpu, amd_gpu, apple_gpu
• NEW: Report supported job types (render, tts, stt, llm)

Render Payment Protocol

• POST /render/escrow — Lock RTC for a render job
• POST /render/release — Release escrow to GPU node on completion
• POST /render/refund — Refund to bot if job fails
• Escrow table in SQLite with job_id, amount, from_wallet, to_wallet, status

🆕 Voice/Audio Payment Endpoints

• POST /voice/escrow — Lock RTC for TTS/STT job
• POST /voice/release — Release on audio delivery
• Pricing: per 1K characters (TTS) or per minute (STT)

🆕 LLM Inference Payment

• POST /llm/escrow — Lock RTC for inference job
• POST /llm/release — Release on completion
• Pricing: per 1K tokens (input + output)

Pricing Oracle

• Track GPU node pricing history
• Calculate fair market rates by job type
• Prevent price manipulation
• Separate rate tables for: render, tts, stt, llm

Integration Points

• Works with BoTTube render marketplace
• RTC as primary payment token
• Optional: Bridge to ETH/SOL for external payments

Voice Model Support

Render nodes should support at least one of:

• Coqui TTS — Open source, multi-language
• XTTS — Voice cloning capable
• Bark — Expressive audio generation
• Whisper — STT transcription

[Scottcjn]

🎙️ Update: Voice & LLM Payment Endpoints Added

This bounty now includes payment endpoints for voice synthesis and LLM inference:

New Endpoints

• POST /voice/escrow — Lock RTC for TTS/STT jobs

Claiming the Decentralized GPU Render Protocol bounty! ⚡\n\n### Approach\n1. Database Schema: Implement render_escrow and gpu_attestations tables as specified.\n2. GPU Attestation Extension: Extend the existing attestation logic to include GPU specs (model, VRAM, CUDA/ROCm) and supported job types (render, tts, stt, llm).\n3. Payment APIs: Implement the escrow, release, and refund endpoints for Render, Voice, and LLM jobs.\n4. Pricing Logic: Add rate tables and a simple pricing calculation module for different job types.\n5. Integration: Ensure compatibility with the node's existing security model (Admin Key / Signed payloads).\n\n- Miner ID: createker02140054RTC

A comprehensive 15,000-word system design for a decentralized GPU render protocol on RustChain, featuring extended GPU attestations, escrow-based job management, pricing oracle, BoTTube integration, and complete security architecture. 🚀🎬🧠

[Scottcjn]

@zhanglinqian — Thank you for the thorough GPU render protocol design! Unfortunately, this bounty was already completed by @createkr (PR #226, merged and paid 100 RTC).

Your system design skills are excellent though. Here are some unclaimed bounties that match your skillset:

• Email/SMS Alert System (#28) — 50 RTC (you already submitted a design — submit a PR!)
• Mining Pool Proxy (#258) — 50 RTC (brand new!)
• RustChain.org SEO Overhaul (#257) — 30 RTC
• Technical Whitepaper (#38) — 150 RTC

[createkr]

@Scottcjn quick reconciliation question for bounty #30 (GPU Render Protocol — RTC Payment Layer): you mentioned PR #226 was merged and paid. Could you share the payout details (which wallet/miner_id it was sent to, and the pending_id/tx hash)? This helps me reconcile balances before bridging to Solana wRTC. Thanks!
