Monetization & Incentives

Reputable introduces several revenue streams, ensuring sustainable incentives for both protocols and contributors:

1. Protocol Fees for Model Deployment: Uniswap and other protocols pay fees to deploy their custom reputation models.
2. Labeling Fees for Verification: Additional fees for verifying and labeling developer profiles within the model.
3. Revenue Sharing for Model Usage: Every time a score is computed, fees are generated and shared between the model creator (Uniswap) and Reputable’s decentralized network of nodes.
4. Tradable ERC-721 Models: Reputation models are ERC-721 tokens, enabling trading, licensing, and renting on marketplaces, thus establishing a new economy for reputation data.
5. Incentives for Developers and Users: Developers and users who generate scores may earn rewards, badges, or other incentives, promoting engagement and ongoing contributions.

Outcome and Impact

Launching a new chain like Unichain typically begins with a blank slate—no transaction history or developer reputation. Uniswap Foundation aims to address this challenge by using Reputable to attract top DeFi developers from the outset. Through Reputable’s reputation-based scoring, Unichain can offer tailored rewards, exclusive opportunities, and faster grant approvals to developers with high reputations, acting as a powerful incentive for them to join and contribute to the new ecosystem. This on-chain reputation model not only incentivizes developers to build on Unichain but also enhances governance by allowing high-reputation developers to have more influence in DAOs. With Reputable, Uniswap establishes a merit-based system that aligns developer contributions with Uniswap’s long-term vision, creating a sustainable ecosystem where rewards and opportunities are aligned with proven impact.

Metrics Definitions for the Reputation Model used for the Dapp

Off-Chain Metrics:

1. Code Contribution: Measures the number of code contributions made by a developer across multiple projects, reflecting overall input and engagement in the ecosystem.
2. Code Influence: Assesses the developer’s influence within projects based on the proportion of code they contributed; greater code ownership signifies higher influence.
3. Recent Activity: Tracks a developer's contribution frequency over the last three months, indicating current engagement levels.

On-Chain Metrics:

1. Txn Engagement: Measures the on-chain activity of deployed code, adjusted by the developer’s contribution, based on transaction volume within smart contracts.
2. User Reach: Indicates the engagement level of unique users interacting with deployed smart contracts, weighted by the developer’s code contribution.
3. TVE (Total Value Enabled): Evaluates the total financial value engaged within a smart contract, proportionate to the developer’s code contribution.

Weighting System

Each metric's weight can be set from 0 to 100, with a final score out of 100 points.

Current Impact Metrics to date:

Total Value Enabled: 233,544,259 ETH in value Total Commits: 135,227 Total Developers: 1,142

This demo captures only developers who contributed to the top 100 DeFi protocols (based on Ethereum Mainnet data from DeFiLlama).

I. Key Features and Infrastructure

Custom Reputation Models

• Protocols can create and deploy custom reputation models tailored to specific use cases or communities.
• Each model is tokenized as an ERC-721 NFT, enabling ownership, transferability, and interoperability with other blockchain ecosystems.

Trustless and Verifiable Computation

• Reputation calculations are executed via smart contracts that verify Sign Protocol attestations and compute scores based on custom model parameters.
• This ensures tamper-proof, sybil-resistant, and transparent computations.

Decentralized Reputation Management

• Reputable decentralizes reputation systems, reducing reliance on centralized authorities and ensuring an immutable audit trail for scores.

Transparency and Auditability

• All reputation model parameters, developer attestations, and score computations are recorded on-chain, ensuring transparency and providing an immutable audit trail.

II. Core Infrastructure & Data Flow

Smart Contract Verification & Transparency

• Blockscout integration ensures verifiable links between deployed smart contracts and their GitHub implementations.
• Developers can verify the code managing their reputation data, enhancing credibility and trust.

Decentralized Attestation System with Sign Protocol

• Sign Protocol is the backbone of data validation.
• Off-chain workers aggregate Web2 and Web3 data, emitting tamper-proof attestations stored off-chain for gas efficiency but provable on-chain via the ReputableHub Contract.

Data Aggregation for Developer Scoring

• On-chain contributions are fetched using Blockscout (verified smart contracts), while off-chain contributions are retrieved from the GitHub API, ensuring a 1-to-1 link between both.
• Aggregated data forms a Sign Protocol Attestation, containing raw data, contributions, and metric scores.

Computation and Minting

• Custom reputation models and developer attestations are executed on-chain, generating trustless and verifiable scores.
• Developers mint their scores using Web3Auth, which ensures secure GitHub authentication and links GitHub IDs to wallets for on-chain minting.
