Blockchain learning roadmap for newbies 2026 - Tan Phat Digital

The Blockchain market in 2026 is shifting strongly from simple financial applications to comprehensive digital economic infrastructure. In Vietnam, the need for human resources does not just stop at knowing how to code, but requires the ability to optimize the system and absolute security. Following the direction from Tan Phat Digital, the training roadmap below focuses on training architectural thinking and practical skills.

Phase I: Blockchain Fundamentals & Cryptography (January-February)

The goal of this phase is to clearly understand the nature of "Distributed Ledger" and mechanisms to ensure data integrity.

1. Blockchain Basics (4 weeks)

• Data Structure: An in-depth study of the Merkle Tree - considered the "digital fingerprint" of the block, helping to authenticate thousands of transactions without downloading the entire data.  

• Consensus mechanism:

  • PoW (Proof of Work): How miners solve the problem of finding the number nonce to match the difficulty of the network.  

  • PoS & DPoS: Validators selection process is based on the number of stakes, speed advantages and energy savings compared to PoW.  

  • BFT/PBFT: The 3-phase consensus process (Pre-prepare, Prepare, Commit) helps the system operate stably even when up to 1/3 of the network nodes fail or are attacked.

2. Cryptography Basics (4 weeks)

• Hash function (Hashing): Distinguish between SHA-256 (Bitcoin) and Keccak-256 (Ethereum). Understand the nature of one-way encryption that helps protect original data.  

• Public Key Cryptography: Use the Private Key pair to sign (Digital Signature) and the Public Key to authenticate the wallet identity.  

simple.

Phase II: Ethereum & EVM Deep Dive (March-April)

This phase helps you master the "heart" of the Ethereum network, which Tan Phat Digital evaluates as the most important to optimize costs and performance.

1. Ethereum Architecture & Account Model

• World State: How Ethereum stores the global state in the form of a Merkle Patricia tree.

• Account Types: Distinguish EOA (user-controlled account with a wallet) and Contract Account (account containing programming code).

• Transactions: Understand gas fee mechanism EIP-1559 (Base fee + Priority fee) to optimize transaction costs.

2. EVM & Opcode Level (In-depth)

• EVM Workspace: Understand the working mechanism of Stack (maximum 1024 items), Memory (temporary memory) and Storage (permanent storage, most expensive).

• Opcodes: Study command codes such as DELEGATECALL (execute code of another contract on state) and STATICCALL (function call does not change state).

• Gas Optimization: Practice "Variable Packing" technique - arrange variables smaller than 32 bytes next to each other so they are in the same storage slot, saving up to 20,000 gas per operation SSTORE.

3. Ethereum Pectra Update (May 2025)

• EIP-7702: Allows a regular wallet (EOA) to act as a smart wallet in a single transaction, supporting gas fee payments with other tokens (Gas sponsorship).

• EIP-7251: Increases staking limit from 32 ETH to 2048 ETH for each validator, helping to reduce the load on the network.

Phase III: Solidity Programming & Advanced Standards (May-July)

This is the stage where you start building complex business logic and complying with industry standards.

1. Solidity & Yul (Assembly)

• Solidity Advanced: Master inheritance, Interfaces, Libraries and error handling with custom errors to save gas compared to require.

• Yul Assembly: Learn how to write low-level code directly in Solidity using the assembly { } keyword. Use sload and sstore to manipulate memory cells directly, bypassing Solidity's layers of safety checks to maximize performance.

2. In-depth Token Standard (ERC)

• ERC-1155: Practice "Batch Transfers" - send hundreds of different tokens in a single transaction, reducing network congestion.  

• ERC-4626 (Tokenized Vaults): The gold standard for DeFi yield pools. Master the deposit (deposit assets to get shares) and redeem (burn shares to get back assets) process.

• ERC-2981 (Royalty Standard): How to signal copyright information (percentage based) to Marketplace platforms to pay author fees.

Practical project: Build a compliant Profit Vault ERC-4626 and a versatile NFT collection using ERC-1155.

Phase IV: Development Tools & Testing Frameworks (August-September)

Professional programmers must know how to automate and ensure source code quality before deployment.

1. Hardhat vs Foundry

• Hardhat: Use for projects that need a large plugin ecosystem (npm) and scripting in JavaScript/TypeScript.  

• Foundry: Used for projects that require extremely fast testing speed. Write tests directly in Solidity and use "Fuzz Testing" to automatically generate thousands of random inputs to find logic errors.  

2. Testing Process (Testing Methodology)

• Fork Testing: Simulate the main network (Mainnet) on the local machine to test interaction with available protocols such as Uniswap or Aave.  

• Static Analysis: Use Slither or Mythril to automatically scan source code and detect common vulnerabilities.

Phase V: Web3 Integration & dApp Development (October-December)

This phase connects the Blockchain infrastructure with end users through a modern Web interface.

1. Frontend Web3 Stack (Modern 2026)

• Wagmi v2 & Viem: Uses modern React Hooks and TanStack Query to manage data state from Blockchain, ensuring real-time UI updates.  

• RainbowKit: Integrates a professional wallet connection interface, supports EIP-6963 standard to help detect wallets automatically and avoid conflicts between browser extensions.  

2. Decentralized Infrastructure

• The Graph: Build Subgraphs to index data from Smart Contract events, help query data quickly via GraphQL.

• Storage: Distinguish between IPFS (suitable for content distribution, needs pinning service) and Arweave (permanent storage on 200 years with just one payment, ideal for Metadata NFT).

Phase VI: DeFi, Security Auditing & Multi-chain (Month 13-18)

The ultimate goal is to become a Blockchain Architect capable of designing secure and multi-chain systems.

1. DeFi Protocol Architecture

• Uniswap V2/V3: Deep understanding of Core (Factory/Pairs) and Periphery (Router) structure. Master in AMM mathematics (x * y = k) and centralized liquidity.  

• Lending & Flash Loans: Build lending pools like Aave, understand the asset liquidation mechanism and how to make Flash Loans without collateral.  

2. Smart Contract Security (Focus)

• OWASP 2025 Vulnerabilities: Master how to prevent Reentrancy (using the Checks-Effects-Interactions pattern), Oracle Manipulation (using Chainlink TWAP), and Access Control flaws (using RBAC/Ownable2Step).  

• Audit Practice: Participate in solving challenges at Ethernaut, Damn Vulnerable DeFi to practice the thinking of a white hat hacker.  

3. Layer 2 & Alternative Chains

• Scaling: Research Optimistic Rollups and ZK-Rollups to process thousands of transactions per second with extremely low fees.

• Aura Network & Cosmos SDK: Learn how to build separate App-chains for businesses (RWA Chain) using Cosmos SDK, similar to large projects in Vietnam today.
