About the platform
Why dypcoe on chain exists and how MST testnet anchors academic records.
03 · The Crisis
Education runs on trust nobody can verify.
Fragmented Web2 infrastructure creates friction for every stakeholder — students, faculty, recruiters, and institutions.
Credential Fraud
Enterprises spend billions on manual background checks. Paper degrees and centralized databases offer zero cryptographic guarantees — a bribed admin can alter any row.
Siloed Identity
Attendance, grades, placements, and club data live in disconnected ERPs. Students rent access to their own history and lose it at graduation.
Biased Hiring
Recruiters rely on keyword-matched profiles with no mathematical proof of competence — creating bottlenecks and reinforcing implicit bias in placements.
Legacy vs Protocol
04 · The Protocol
Five layers of cryptographic truth.
SIWE identity, gasless relayer issuance, IPFS storage, soulbound credentials, and zero-knowledge privacy — one integrated stack.
Five OS Portals
Next.js 16
NestJS API
Auth · Relayer · ZK
PostgreSQL
77 models
IPFS / Pinata
Metadata
MST Blockchain
SBT · RBAC · ZK
AI Copilot
Gemini
Identity Layer
SIWE + JWT
Nonce-bound wallet login binds one key pair to the academic graph across five role-based OS portals.
Issuance Layer
EIP-712 Relayer
Faculty sign off-chain; the NestJS relayer verifies ISSUER_ROLE, pins metadata to Pinata, and executes gas-sponsored mints.
Storage Layer
IPFS / Pinata
Credential and document metadata pinned immutably. Real CIDs enforced when DEMO_MODE=false — uploads fail closed without Pinata.
Trust Layer
CredentialRegistry SBT
Non-transferable soulbound tokens with on-chain issuer verification. RevocationRegistry for institutional control.
Privacy Layer
Circom / Groth16
Students prove eligibility thresholds (e.g. trust score > 85) without revealing raw transcript data. Verifier live at 0xdCdB3a6b… on MST.
05 · Issuance Flow
Gasless credential minting.
Faculty never pay gas. The relayer intercepts EIP-712 signatures, pins to IPFS, and executes on-chain — adoption without crypto friction.
Faculty Signs
Professor signs an EIP-712 structured payload with MetaMask. Zero gas — pure cryptographic intent.
Relayer Validates
API verifies ISSUER_ROLE on GovernanceRegistry, simulates the tx, checks relayer balance, and rejects mock IPFS.
IPFS Pin
Grade metadata is pinned via Pinata on Render. The immutable CID becomes the credential URI anchor.
SBT Minted
Relayer submits the meta-transaction. CredentialRegistry mints a soulbound token to the student wallet on MST Testnet.
06 · Why MST
The perfect engine for a network state.
MST Blockchain delivers the throughput, finality, and meta-transaction support a real campus demands — onboarding thousands of students into Web3 without friction.
Gasless Institutional UX
Students and faculty never buy crypto for gas. EIP-712 meta-transactions on MST let the university relayer treasury sponsor issuance — faculty sign, contracts execute.
Immutability Meets Zero-Knowledge
Soulbound credentials cannot be transferred on MST. Recruiters verify competence via Groth16 proofs without seeing raw grades — cryptographic truth without surveillance.
Pilot-Ready Testnet Stack
70+ deployed proxies, persisted chain indexer, health checks for DB/Redis/RPC/IPFS/relayer — built for institution pilots before mainnet.
