Development Summary for SIP: Standard Reputation Framework and NFT Minting for Reputation Badges

Preamble

SIP Number: XXX
Title: Standard Reputation Framework and NFT Minting for Reputation Badges

Status: Draft

Abstract

This SIP proposes a framework for implementing a standard reputation system on apps or websites. Each reputation transaction results in the minting of a Non-Fungible Token (NFT) to provide a verifiable, immutable record of the reputation event. This proposal outlines the standard attributes for the reputation system, the structure for XML and JSON representation, and the NFT minting process.

Motivation

A standardized reputation system with blockchain integration provides several benefits:

1. Transparency and Trust: Immutable records of reputation transactions increase transparency.
2. Interoperability: Standardized attributes allow for consistent implementation across different platforms.
3. Ownership: Minted NFTs represent a user’s reputation transactions, providing verifiable proof of reputation that users own.
4. Gamification: NFTs can be used to 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, downvote, review).
• event_description: A description of the reputation event.
• event_timestamp: The timestamp when the event occurred.
• event_value: The value of the reputation change (positive or negative).

NFT Information

• nft_id: A 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 on the platform (e.g., a user receives an upvote).
2. Data Aggregation: The platform collects the necessary data for the reputation transaction.
3. NFT Creation: The platform generates an NFT with the collected data as metadata.
4. Blockchain Interaction: The platform interacts with a blockchain service to mint the NFT.
5. Storage and Access: The minted NFT’s URL and metadata are stored in the platform’s database and linked to the user’s profile.

Rationale

This framework leverages the immutability and transparency of blockchain technology to create a verifiable and trustworthy reputation system. By standardizing the attributes and using NFTs to record reputation transactions, users gain ownership and can showcase their reputation across different platforms.

Backwards 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

Implementing this proposal requires:

1. Database Changes: Modify the database to store the new reputation and NFT attributes.
2. Blockchain Integration: Implement the logic to interact with a blockchain service for minting NFTs.
3. API Development: Develop APIs to handle reputation transactions and provide data in the specified formats.
4. Frontend Changes: Update user interfaces to display reputation and NFT information.

Security Considerations

• Data Privacy: Ensure user data is handled securely and with consent.
• Blockchain Risks: Mitigate risks associated with blockchain interactions, such as transaction costs and potential delays.

Conclusion

This SIP provides a standardized approach to implementing a reputation system with blockchain integration. By minting NFTs for each reputation transaction, we create a transparent, verifiable, and user-owned record of reputation, enhancing trust and engagement across platforms.

Example where the Stacks Foundation gives a skill badge for "Critical Bounty" as a form of skill verification:

(define-data-var user_id (string-ascii 50) "user-stx-address")
(define-data-var skill_id (string-ascii 50) "critical-bounty-001")
(define-data-var skill_name (string-ascii 50) "Critical Bounty Completion")

(define-data-var verifier_id (string-ascii 50) "stacks-foundation")

(define-public (award-skill-badge (user_id (string-ascii 50))
                                  (skill_id (string-ascii 50))

    (begin
        ;; Mint an NFT representing the skill badge (this would involve a separate NFT contract)
        (print (tuple (user user_id)
                      (skill-id skill_id)
                      (skill-name skill_name)

                      (verifier verifier_id)))
        (ok (tuple (user user_id)
                   (skill-id skill_id)
                   (skill-name skill_name)
                   (timestamp verification_timestamp)
                   (verifier verifier_id)))
    )
)

Explanation:

• user_id: This is the Stacks address of the user who completed the critical bounty.
• skill_id: A unique identifier for the skill, in this case, associated with the "Critical Bounty Completion."
• skill_name: The name of the skill being awarded, here "Critical Bounty Completion."
• verification_timestamp: The timestamp when the skill was verified.
• verifier_id: The identifier of the entity verifying the skill, in this case, "stacks-foundation."

The award-skill-badge function can be called to log the awarding of the skill badge. This could later be expanded to include minting an NFT that represents this skill badge on the blockchain.
