User Verification Examples
Example A: On-Chain Task Verification
Scenario: User wants to earn "DeFi Expert" SBT by completing on-chain activities
Verification Flow:
User connects wallet to TBook platform
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
System queries blockchain data via Sui RPC:
Verifies transaction history
Checks liquidity pool positions
Validates governance participation records
All criteria met → TBook generates time-limited signature
User receives signature and calls mint() function
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:
User connects Twitter/Discord accounts to TBook
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
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
All tasks completed → Generate signature with user's wallet address
User calls mint() with signature on Sui blockchain
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
