Standard Reputation Framework

Reputation Framework User Guide V.0.1 first draft. Reputation and NFT Minting for Reputation Badges.

Created: 2024-05-01 License: MIT License

Abstract

This SIP proposes a framework for implementing a standardized reputation system on apps or websites. Reputation transactions will result in the minting of Non-Fungible Tokens (NFTs) to provide a verifiable and immutable record of reputation events. The proposal outlines standard attributes for reputation systems, the structure for XML and JSON representation, and the NFT minting process.

Motivation

A standardized blockchain-based reputation system provides several benefits:

1. Transparency and Trust: Immutable records of reputation transactions increase transparency.

2. Interoperability: Standard attributes allow consistent implementation across platforms.

3. Ownership: Minted NFTs serve as proof of ownership, providing users with verifiable reputation.

4. Gamification: NFTs incentivize positive behavior and engagement.

Specification

Standard Attributes

User Information

• user_id: A unique identifier for the user.

• username: The display name of the user.

• profile_url: URL to the user's profile.

Reputation Event

• event_id: A unique identifier for the reputation event.

• event_type: The type of reputation event (e.g., upvote, review).

• event_description: Description of the event.

• event_timestamp: Timestamp when the event occurred.

• event_value: Reputation change value (positive or negative).

NFT Information

• nft_id: Unique identifier for the minted NFT.

• nft_url: URL to the NFT on the blockchain.

• nft_metadata: Metadata associated with the NFT, including details of the reputation event.

Clarity Code Representation

(define-data-var user_id (string-ascii 50) "unique-user-id")
(define-data-var username (string-ascii 50) "username")
(define-data-var profile_url (string-ascii 100) "https://example.com/user/profile")

(define-data-var event_id (string-ascii 50) "unique-event-id")
(define-data-var event_type (string-ascii 20) "upvote")
(define-data-var event_description (string-ascii 100) "Received an upvote on a comment")
(define-data-var event_timestamp (buff 32) 0x1234567890abcdef)
(define-data-var event_value int 10)

(define-data-var nft_id (string-ascii 50) "unique-nft-id")
(define-data-var nft_url (string-ascii 100) "https://blockchain.com/nft/unique-nft-id")
(define-data-var nft_metadata (buff 1024) 0xBase64EncodedMetadata)

NFT Minting Process

1. Event Trigger: A reputation event occurs (e.g., user receives an upvote).

2. Data Aggregation: Necessary data is collected.

3. NFT Creation: NFT is generated with event data as metadata.

4. Blockchain Interaction: The platform interacts with a blockchain service to mint the NFT.

5. Storage and Access: The NFT’s URL and metadata are stored in the platform’s database and linked to the user’s profile.

Rationale

By leveraging blockchain technology, this framework ensures transparency and trustworthiness. Standardizing attributes and using NFTs to represent reputation events gives users ownership of their reputation, which can be showcased across platforms.

Backward Compatibility

This proposal introduces a new system and does not affect existing implementations. Platforms adopting this standard will need to integrate the reputation framework and NFT minting process.

Implementation

Key steps include:

1. Database Changes: Modify database structures to store reputation and NFT attributes.

2. Blockchain Integration: Develop logic to interact with blockchain services for NFT minting.

3. API Development: APIs must handle reputation transactions and provide data in the defined formats.

4. Frontend Changes: Update UI to display reputation and NFT information.

Security Considerations

• Data Privacy: Ensure proper handling of user data with consent.

• Blockchain Risks: Consider risks related to transaction costs and delays in blockchain interaction.

Conclusion

This SIP offers a standardized approach for integrating reputation systems with blockchain technology. By minting NFTs for each reputation transaction, the framework ensures transparency, verifiability, and ownership, enhancing trust and engagement on decentralized platforms.
