Smart Contract Architecture​

Business Registry Contract​

interface BusinessRegistry {
  registerBusiness(details: BusinessDetails): BusinessId;
  updateBusiness(id: BusinessId, updates: Partial<BusinessDetails>): void;
  verifyBusiness(id: BusinessId): VerificationStatus;
  getBusiness(id: BusinessId): Business;
}

Feedback Engine Contract​

interface FeedbackEngine {
  submitFeedback(businessId: BusinessId, feedback: Feedback): FeedbackId;
  validateFeedback(feedbackId: FeedbackId): ValidationResult;
  calculateReputation(userId: UserId): ReputationScore;
  distributeRewards(feedbackId: FeedbackId): TokenAmount;
}

DAO Token Contract​

interface DAOToken {
  mint(recipient: Principal, amount: TokenAmount): void;
  transfer(from: Principal, to: Principal, amount: TokenAmount): void;
  stake(amount: TokenAmount): StakeReceipt;
  vote(proposalId: ProposalId, vote: Vote): void;
}

Security Features​

Multi-Layer Security​

  1. Smart Contract Audits: Regular security reviews
  2. Encryption: End-to-end data protection
  3. Access Control: Role-based permissions
  4. Rate Limiting: DDoS protection

Anti-Fraud Mechanisms​

  • Sybil Attack Prevention: One person, one voice
  • Review Bombing Protection: Temporal distribution analysis
  • Fake Review Detection: AI-powered validation
  • Reputation Weighting: Trust-based influence

Integration Options​

For Web2 Applications​

// REST API Example
const vexAPI = new VexAPI({
  apiKey: 'your-api-key',
  endpoint: 'https://api.vex.network'
});

// Submit feedback
const feedback = await vexAPI.submitFeedback({
  businessId: 'business-123',
  rating: 5,
  comment: 'Excellent service!',
  verified: true
});

// Get business reputation
const reputation = await vexAPI.getReputation('business-123');

For Web3 DApps​

// ICP Integration Example
import { Actor, HttpAgent } from '@dfinity/agent';
import { idlFactory } from './vex.did.js';

const agent = new HttpAgent();
const vexActor = Actor.createActor(idlFactory, {
  agent,
  canisterId: 'your-canister-id'
});

// Submit on-chain feedback
const result = await vexActor.submitFeedback({
  businessId: Principal.fromText('business-principal'),
  rating: BigInt(5),
  comment: 'Great experience!',
  proof: verificationProof
});
