DotRepute is a real-time, blockchain-powered reputation engine built natively for the Polkadot ecosystem. It transforms fragmented on-chain activity into transparent, verifiable, user-owned reputation profiles — similar to how LinkedIn, GitHub, and StackOverflow shape identity in Web2.

DotRepute leverages PolkadotJS API, Identity, OpenGov, and Staking pallets to compute a multi-dimensional reputation score for any address on the network. It includes a fully interactive AI-powered dashboard, wallet connection, real-time score computation, and clear reputation breakdowns.

This project was built for the Polkadot “Bring Web2 Applications to Web3” Hackathon under the theme:

User-Centric Apps — Real-World Web3 Impact Using Polkadot Technology Stack

A multi-dimensional scoring model using five weighted components:

• Identity Score (25%) – Fields completeness + registrar verification
• Governance Score (25%) – Referenda participation and voting activity
• Staking Score (20%) – DOT staked, nominations, validator trust
• Activity Score (20%) – Frequency of extrinsics and on-chain operations
• Development Score (10%) – GitHub contribution signals (Roadmap)

The system pulls data directly from Polkadot — no caching, no intermediaries.

A conversational interface that explains:

• Why a user received their score
• Identity breakdown
• Governance participation metrics
• Staking insights
• Trust tier and percentile ranking
• Personalized improvement recommendations
• 30-day and 90-day score trends
• Validator and nominator analysis

Users can chat with their own reputation, similar to ChatGPT — but powered by Polkadot data.

• Seamless Polkadot wallet connection
• Automatic score generation on connect
• Real-time updates when wallet activity changes

• One-click export of entire conversation
• Generates professional .docx reports
• Useful for grants, job applications, DAO membership, validator profiles

• Next.js 14 App Router
• TailwindCSS v4
• Framer Motion animations
• Dark modern dashboard
• Fast, responsive interactions

• Next.js 14
• React + TypeScript
• TailwindCSS v4
• Luno Kit for Polkadot wallet integration
• Framer Motion

• @polkadot/extension-inject
• @polkadot/util / util-crypto

• ink! smart-contract-based on-chain reputation storage
• SubQuery indexing for historical data

git clone https://github.com/<your-repo>/DotRepute.git
cd DotRepute

cd frontend

Install any Polkadot-compatible wallet extension:

• Talisman
• Polkadot.js Extension
• SubWallet

DotRepute works seamlessly with them via Luno Kit.

score =
  identity * 0.25 +
  governance * 0.25 +
  staking * 0.20 +
  activity * 0.20 +
  development * 0.10

Each component is computed using verifiable, real-time on-chain data.

Identity fields include:

• Display name
• Legal name
• Email
• Web
• Twitter
• Riot/Matrix
• Registrar judgements

Governance pulls from: convictionVoting.votingFor(address)

Staking pulls from: staking.ledger(address) staking.nominators(address)

All technical documents are available under /docs including:

• scoring-model.md
• architecture.md
• data-sources.md
• api-spec.md
• roadmap.md

• “What is my identity score?”
• “Show my governance participation.”
• “Breakdown my staking score.”
• “How can I increase my reputation?”
• “Show my 30-day reputation trend.”
• “Explain my DotRepute score like I’m 12.”

DotRepute perfectly aligns with the Polkadot hackathon pillars:
