8 Tracks.
One System.
The evolution from a confused beginner to a production-grade systems engineer. Every track centres around a shipped, deployed product — not a toy demo.
Blockchain Foundations
Blockchain Foundations — Start with the physical reality of nodes, RPCs, and gas.
Figure out where data lives, how RPCs connect your app, and why gas isn't arbitrary—before writing a single line of Solidity.
Visual Blockchain Simulator
Students build a transaction flow simulator, block visualizer, node propagation animation, and gas simulation system — using vanilla JS + SVG.
The trust problem — why do we need banks?
Double-spend problem. Why digital money failed before Bitcoin. The human cost of centralized trust.
Centralized vs decentralized systems
Single point of failure. Censorship. Downtime. Why decentralization solves specific problems.
What blockchain actually invented
Not just a database. A consensus mechanism for untrusted parties. The Nakamoto breakthrough.
Where blockchain SHOULD NOT be used
The most important lesson in T0. If a database works, use a database. Blockchain is a trust primitive.
Solidity & Smart Contract Engineering
Solidity & Smart Contract Engineering — Code your first smart contracts (ChainLock & ChainTask).
Understand storage slots, events, security patterns, and access control. Every lesson uses real code from shipped projects, not simple syntax templates.
Evolutionary Voting System
Intentionally starts with a broken architecture (voter data stored on-chain), hits gas failures in practice, and evolves through optimization to a production-grade contract.
Full Stack Web3
Full Stack Web3 — Ship your first complete voting dApp (ChainElect) backed by Supabase.
Start with a naive React and MetaMask prototype, watch it fail in production, and rewrite it. We'll solve real-world problems: scaling reads, caching IPFS, and indexing events.
ChainElect — Socio3 Classic → Evolution
Start with the naive React+MetaMask+direct-contract architecture. Watch it break at scale. Evolve it through backend introduction, Redis caching, and The Graph indexing until it becomes production-grade.
Blockchain System Design
Blockchain System Design — Build decentralized solutions to real-world problems (ProofChain & ChainCure).
Figure out where boundaries lie, when to store off-chain, and how to model trust. We'll dissect the real architecture of Uniswap, ProofChain, and Socio3.
ProofChain
Production-grade proof-of-existence system: file hashing on the frontend, IPFS storage, on-chain hash registry, event indexing, hybrid architecture.
The Death of Traditional Web3 UX
The Death of Traditional Web3 UX — Build next-gen sponsored UX using erc4337-kit & ChainNotesV2.
MetaMask is terrible for consumer onboarding. Build modern login flows using social sign-ins, embedded wallets, and gasless smart accounts.
Socio3 V2
Rebuild the Socio3 Classic social network with Privy embedded social authentication, Pimlico gas sponsorship, and useroperation batching.
Zero Knowledge & Privacy Engineering [WIP]
Zero Knowledge & Privacy Engineering — Master zkSNARKs with Circom, Soulbound NFTs, and Zkredential.
Prove credentials dynamically. Compile Circom circuits, build witness generators, Poseidon hashing, and mint soulbound NFT credentials.
ZK Credential Verifier
Based on ZKredential — MIT hackathon top-15. Circom circuits, Groth16 proofs, Poseidon hashing, ERC-5192 Sbound NFTs, Polygon Amoy.
Security & Production Engineering
Security & Production Engineering — Protect protocols and distribute paper via ZeroLeak.
Prevent replay attacks, distribute trust using Shamir Secret Sharing, design timelocks, and build backup RPC infrastructure so your app survives mainnet.
ZeroLeak
Exam paper leak prevention system: PDF encrypted in-browser with AES-256-GCM, encryption key split using Shamir Secret Sharing, smart contract timelock.
Real-World Blockchain Systems
Real-World Blockchain Systems — Orchestrate indexers, node clusters, and production networks.
Dissect fully deployed production systems. Fake drugs, exam leaks, and credential privacy—solving real problems with real systems.
ChainCure + CiviChain
ChainCure: pharmaceutical anti-counterfeiting with 5-actor supply chain, QR verification. CiviChain: civil material authentication.
