User Verification Examples

Example A: On-Chain Task Verification

Scenario: User wants to earn "DeFi Expert" SBT by completing on-chain activities

Verification Flow:

  1. User connects wallet to TBook platform

  2. System checks on-chain requirements:

  • Has swapped tokens worth at least $1,000 on designated DEX

  • Has provided liquidity for at least 30 days

  • Has participated in at least 3 governance votes

  1. System queries blockchain data via Sui RPC:

  • Verifies transaction history

  • Checks liquidity pool positions

  • Validates governance participation records

  1. All criteria met → TBook generates time-limited signature

  2. User receives signature and calls mint() function

  3. SBT successfully minted and bound to wallet

Key Verification Points:

  • Transaction authenticity verified via blockchain explorer

  • Minimum value requirements checked

  • Time duration requirements validated

  • All checks must pass before signature issuance

Example B: Social Task Verification

Scenario: User wants to earn "Community Builder" SBT by completing social media tasks

Verification Flow:

  1. User connects Twitter/Discord accounts to TBook

  2. System checks social task requirements:

  • Follow project's official Twitter account

  • Retweet and like the campaign post

  • Join Discord server and verify role

  • Invite at least 5 friends who complete tasks

  1. TBook verification service checks each task:

  • Twitter API verifies follow/retweet/like status

  • Discord bot confirms server membership and role

  • Referral system validates invited friends' completion

  1. All tasks completed → Generate signature with user's wallet address

  2. User calls mint() with signature on Sui blockchain

  3. SBT minted after on-chain signature verification

Key Verification Points:

  • OAuth authentication for social account binding

  • Real-time API calls to verify task completion

  • Anti-fraud checks (bot detection, fake accounts)

  • Referral chain validation

  • Only genuine completion triggers signature generation

Verification and Signature Mechanism

Dual Verification System

Business Layer Verification (Off-chain)

Purpose: Ensure only qualified users can obtain minting permissions

Process:

User Application → Project Review → Business System Verification → Generate Minting Eligibility

Verification Content:

  • User identity authenticity

  • Proof materials for completed tasks

  • Whether conditions are met

  • Prevention of duplicate applications

Technical Layer Verification (On-chain)

Purpose: Ensure security and legitimacy of minting process

Signature Mechanism:

// Signature message format

const message = `${contractAddress}|${collectionId}|${timestamp}|${userAddress}|${sbtId}`;

// Sign using Ed25519 algorithm

const signature = ed25519.sign(message, privateKey);

Verification Elements:

  • Contract Address: Ensure operation on correct contract

  • Collection ID: Verify user is minting from correct collection

  • Timestamp: Prevent signature replay attacks (15-minute expiration)

  • User Address: Ensure only designated user can use the signature

  • SBT ID: Guarantee uniqueness of each SBT

Security Guarantee Mechanisms

Time-based Control
  • ignatures automatically expire after 15 minutes

  • Prevent malicious use of old signatures

  • Ensure real-time nature of minting process

Duplicate Protection

Same user can only mint once per collection

Prevent obtaining duplicate identical credentials

Maintain credential scarcity and meaning

Permission Control

Only users with valid signatures can mint

Administrators can pause entire system

Collection creators have independent management permissions

Real Application Cases

Case 1: Social Media Engagement Campaign

Application Scenario:

  • Issue "Community Ambassador" SBT to active social media participants

  • Users must complete off-chain social tasks: follow Twitter account, retweet campaign posts, join Discord server, invite 5 friends

  • TBook verification system checks task completion before issuing signature

  • SBT grants access to exclusive NFT whitelists and community events

Case 2: DeFi Community Governance

Application Scenario:

  • Issue "Governance Committee Member" SBT to active governance participants

  • Users must participate in at least 10 proposal votes

  • SBT holders gain advanced governance permissions

Case 3: Gaming Achievement System

Application Scenario:

  • Issue "Hero" SBT to players who clear difficult dungeons

  • Only top 100 players server-wide can obtain it

  • SBT has special value in game ecosystem
