Blockchain Implementation​

Smart Contract Overview​

Contract Purpose:

  • Store verification metadata
  • Emit verification events
  • Enable public verification queries
  • Manage creator attribution

Key Functions:

  • createVerification() - Create new verification record
  • verifyAudio() - Check audio authenticity
  • getVerification() - Retrieve verification data
  • updateVerification() - Admin updates only
Blockchain Selection

Platform will use Polygon (MATIC) for lower gas fees and faster transactions.

IPFS Integration​

Stored on IPFS:

  • Audio file hash (not full file)
  • Metadata JSON
  • Certificate data
  • Verification proof

Benefits:

  • Decentralized storage
  • Immutable references
  • Content addressing
  • Cost efficiency

Acceptance Criteria​

F7.1 - Blockchain Authentication​

User Story: As user, I want blockchain-verified authentication to prove ownership.

Acceptance Criteria:

  • AC7.1.1: Given I want blockchain verification, when I create account, then can optionally link cryptocurrency wallet
  • AC7.1.2: Given I link wallet, when I log in, then can authenticate using wallet signature instead of password
  • AC7.1.3: Given I use blockchain auth, when I access platform, then identity cryptographically verified with trust badge
  • AC7.1.4: Given wallet auth fails, when connection issues occur, then can fall back to email/password
  • AC7.1.5: Given I disconnect wallet, when I manage settings, then can safely unlink while preserving traditional access
  • AC7.1.6: Given multiple wallets, when I authenticate, then can choose preferred wallet from connected options
  • AC7.1.7: Given blockchain network congested, when I authenticate, then system provides estimated wait and alternatives

F7.2 - Content Verification​

User Story: As content creator, I want audio verified on blockchain.

Acceptance Criteria:

  • AC7.2.1: Given request completed, when admin uploads audio, then content hash recorded on blockchain within 1 hour
  • AC7.2.2: Given content on blockchain, when anyone views playback, then verification badge with blockchain record link
  • AC7.2.3: Given I prove ownership, when I access projects, then can generate cryptographic proof of creation
  • AC7.2.4: Given someone questions authenticity, when they check blockchain, then can verify creator, date, content integrity
  • AC7.2.5: Given content modified, when audio edited, then new blockchain entry created linking to original with history
  • AC7.2.6: Given blockchain transaction fails, when network issues occur, then verification queued and retried with notification
  • AC7.2.7: Given I want certificate, when I request, then can download printable certificate with QR linking to blockchain proof

F7.3 - Voice Actor Attribution​

User Story: As voice actor, I want blockchain attribution for my work.

Acceptance Criteria:

  • AC7.3.1: Given I'm voice actor, when audio completed, then contribution recorded on blockchain with immutable attribution
  • AC7.3.2: Given I track work, when I access dashboard, then see all projects with blockchain verification links
  • AC7.3.3: Given content becomes popular, when usage increases, then blockchain enables transparent royalty calculations
  • AC7.3.4: Given I prove experience, when I apply elsewhere, then can reference verified blockchain portfolio
  • AC7.3.5: Given licensing disputes, when conflicts occur, then blockchain provides indisputable evidence of contribution
  • AC7.3.6: Given I want attribution control, when I complete work, then can choose level of public attribution
  • AC7.3.7: Given smart contracts implemented, when projects generate revenue, then royalty payments automatically distributed

F7.4 - Verification Badge System​

User Story: As anyone viewing content, I want to easily verify authenticity.

Acceptance Criteria:

  • AC7.4.1: Given content blockchain verified, when I view playback, then clear verification badge visually stands out
  • AC7.4.2: Given I click badge, when I want details, then popup with: verification date, creator, voice actor, blockchain link
  • AC7.4.3: Given I verify manually, when I access blockchain link, then view transaction on public explorer
  • AC7.4.4: Given content lacks verification, when I view unverified, then clear indication content not blockchain verified
  • AC7.4.5: Given verification pending, when blockchain processing, then "verification pending" with estimated completion
  • AC7.4.6: Given I'm technically savvy, when I examine verification, then can access raw blockchain data and cryptographic proofs

  • Voice actor identity verified
  • Platform signature required
  • Cryptographic proof of origin
