PromptHub is the onchain economy for AI prompt creators, turning prompts into tradable assets with NFT ownership, escrow freelancing, and brand contests powered by smart contracts on 0G. (26 Words)


Short Description

PromptHub is the ownership and monetization layer for the generative AI economy.

Transform AI prompts from disposable text into verifiable, tradable, and programmable onchain assets. Built on 0G’s modular infrastructure, PromptHub combines 0G Storage for tiered data security, 0G Compute for AI-powered quality scoring, NFT-based ownership, automated royalties, and trustless escrow into one creator economy platform.

  • For creators, PromptHub turns intellectual property into liquid digital assets.

  • For buyers and autonomous agents, it provides verified access to high-quality AI prompts unlocked instantly via the x402 payment protocol.

  • For brands, it enables onchain contests and direct creator engagement.

  • For the ecosystem, our AgentRegistry creates the financial operating system for AI-native intellectual property.

As generative AI scales toward a trillion-dollar market, the next major opportunity is not only model access, but ownership of the intelligence layer built on top of those models.

PromptHub is building that layer: the world’s first programmable marketplace where AI prompts, workflows, and agent-ready knowledge assets can be tokenized, licensed, traded, and monetized globally.

0G Components Used:

  1. 0G Chain
    Hosts PromptHub’s core smart contracts, including Marketplace, Escrow Hire, Contests, Treasury, and AgentRegistry, enabling trustless marketplace transactions, freelance escrow, brand contests, treasury logic, creator identity, and reputation on-chain.

  2. 0G Storage
    Provides decentralized storage for encrypted prompt content, attachments, images, files, and critical assets, with Merkle root hash verification to ensure data integrity. It is also integrated with Pinata for supporting asset delivery.

  3. 0G Compute / AI Inference
    Uses AI inference, including 0GM-1.0-35B-A3B, to power automated Prompt Quality Scoring, Plagiarism Detection, and preview prompt generation before purchase.

  4. Agent ID / AgentRegistry
    Provides verified on-chain identity for AI creators, connecting creator profiles directly to hire, reputation, ownership, and marketplace trust features.

    (In the future, PromptHub will become the marketplace where AI agents autonomously discover, purchase, interact, and evolve through intelligence assets such as prompts, workflows, datasets, programs, and model instructions.)


Core Products


Problem

The AI prompt market is growing rapidly, but it still operates on trust-based systems.

No Ownership Proof

Creators rely on centralized platforms with no on-chain provenance.

No Secure Freelancing

Many platforms take high fees and do not provide trustless escrow systems for freelance work.

No Composability

Prompts are often static assets and cannot be reused programmatically across applications.

No Analytics

Creators lack visibility into prompt performance, sales, earnings, and user demand.

AI creators produce valuable intellectual property, but they lack the infrastructure to own, monetize, and protect it.


Solution

PromptHub introduces a fully on-chain operational layer on the 0G blockchain.

It combines a real-time Web2 experience with decentralized ownership, verifiable digital assets, and trustless financial execution


Technical Architecture


How It Works


Live Status

Why 0G Blockchain

0G provides high-performance infrastructure optimized for AI-native applications.

It supports scalable smart contracts, decentralized storage, and fast execution, making it suitable for building a global AI asset economy.

PromptHub uses 0G as the foundation for verifiable ownership, trustless payments, decentralized storage, and AI-focused asset infrastructure.


Competitive Advantage

PromptHub brings multiple creator economy features into one platform.

On-Chain Ownership

Creators can prove ownership and provenance of their prompts through NFTs.

Trustless Escrow

Freelance payments are secured through smart contracts instead of centralized intermediaries.

Automated Royalties

Creators can earn from resale activity through on-chain royalty logic.

Low Platform Fee

PromptHub uses a 2.5% platform fee, making it more creator-friendly than many traditional marketplaces.

Decentralized Storage & AI Tooling

Leverages 0G Storage for secure, encrypted asset delivery with Merkle root verification, combined with 0G Compute for AI-powered quality scoring and plagiarism prevention.

Verifiable Transactions

Purchases, ownership transfers, escrow releases, and payouts are recorded on-chain.

Real-Time Analytics

Creators can monitor earnings, performance, and activity through the dashboard.


Bounty Alignment

Infrastructure

PromptHub includes a full smart contract system on 0G with native storage integration and direct RPC verification.

Innovation

PromptHub treats prompts as financial assets. By combining the x402 payment protocol, AgentRegistry, and 0G Compute, it creates a fully programmable marketplace where AI agents can autonomously discover, purchase, and consume prompts.

Creator Experience

PromptHub gives creators a professional dashboard with real-time analytics, automated earnings, secure transactions, and communication tools.


Vision

PromptHub builds the ownership layer for AI intellectual property.

Today, creators can mint and sell prompts as on-chain assets.

Next, AI agents will be able to trade prompts autonomously.

In the future, prompts, workflows, and AI models can become fully tradable components on 0G.

PromptHub is a blockchain-native AI economy where creators own their work and buyers receive verifiable value.

本次黑客松进展

PromptHub successfully migrated to the 0G Network ecosystem. Core flows such as marketplace purchases, escrow hire, and contests now run on-chain through 0G EVM, with asset data stored on 0G Storage and AI scoring supported by 0G Compute.
