🧠Snark Market

This page explains how to set up a provider for the Curio Snark Market (experimental).

⚠️ Experimental Feature in Testing This feature is currently experimental and under active testing. Interfaces, behaviors, and requirements may change without notice.

🔧 What is the Snark Market?

The Snark Market allows any Curio node — including Storage Providers with spare sealing/GPU capacity — to sell or buy proof computation in exchange for FIL. It is designed for GPU nodes that want to participate in Filecoin proof offloading, enabling a decentralized proof marketplace.

This guide will walk you through how to:

  • Enable proof selling on GPU nodes

  • Set up the pricing and wallet

  • See activity and settlement stats in the UI

⚙️ Prerequisites

Before enabling the Snark Market on your node:

⚙️ System Requirements

  • Modern NVIDIA GPU (recommended 12GB+ VRAM)

  • Curio from origin/feat/snkss branch (Snark Market support)

  • FIL balance on Mainnet

🚀 Setup Instructions

1. Install Curio

First, install dependencies (as per the main install guide):

sudo apt update
sudo apt install -y build-essential pkg-config libssl-dev curl git clang cmake golang

Then, build Curio from the Snark Market branch:

git pull
git checkout origin/feat/snkss
git submodule update
make clean
RUSTFLAGS="-C target-cpu=native -g" FFI_BUILD_FROM_SOURCE=1 FFI_USE_CUDA_SUPRASEAL=1 make clean build all
sudo make install
sudo systemctl start curio.service

🛠️ Step-by-step Setup

2. Enable the Market in Layer Configuration

Ensure you're not running on a WindowPoSt node. This is only supported on GPU-based PoRep or Snap nodes. In the Web UI:

  1. Go to Overview → Configuration

  2. Find the Subsystems section

  3. Enable proof_share or Enable Snark Market

  4. Save and restart the node

Enable PROOFSHARE toggle in configuration
Enable PROOFSHARE from the configuration layer

3. Configure Provider Settings

Navigate to Snark Market in the sidebar. Under Provider Settings:

  • Enable the settings checkbox

  • Create a new f1 wallet (do not reuse existing wallet) ⚠️ Please note: This wallet can be changed later, but it is tricky

  • Set Price (FIL/p) to 0.005 (recommended for testing)

    • Single proof (p) should take roughly two minutes to compute, your price should be calculated based on how many proofs per hour per GPU you expect to compute and your cost to run the GPU. The snark marketplace automatically adjusts the market price to match supply to demand.

  • Click Update Settings

4. Verify Your Node

Once you've configured the provider settings:

  • Your node will automatically begin queueing proof work

  • The dashboard will update with:

    • Active Asks

    • SNARK Queue

    • Payment Summaries

    • Recent Settlements

🪙 Wallet Setup Notes

  • Create a new f1 address and fund it (e.g. 0.1 FIL)

  • This wallet receives SNARK proof rewards

  • Ensure the wallet remains unlocked

📈 Pricing & Payments

  • Price is set per ~130M proof constraints (default granularity)

  • Suggested testing price: 0.005 FIL

  • Settlements occur automatically when network gas fee to settle is less than 0.2% of the balance to settle

🧪 Notes

  • Your provider must complete 50 challenge proofs per "work-slot"

  • Each "work-slot" is allows for either one "work ask" in the market - listing of readiness to take on work on one proof for some minimum price, or one "assigned proof" which is being actively worked on.

  • Number of work slots is calculated by dividing "completed challenge proofs" by 50

  • Failure to complete assigned work within the deadline reduces "completed challenge proofs" balance by 50 proofs

  • Withdrawing an ask from the market (i.e. in order to adjust ask price) reduces "completed challenge proofs" balance by 1 proof

  • "challenge proofs" are gained only by completing unpaid challenge proofs, which are assigned when attempting to create a work ask while the challenge balance is too low.

  • The service may assign real proofs as challenges, but only if they were failed by other providers and no other provider can be found who can take the payment

  • Proofs must complete within 45 minutes, or your node will lose its active slot and need to re-earn trust

  • The system is fault-tolerant and retries failed work automatically

    • You may be assigned retry proofs which come with non-current, potentially lower than current, still higher than your minimum price per proof.

  • You can scale horizontally by running more GPU workers with the same setup
