VeChain Hayabusa | Academy

Concise guide to the essence, mechanics, applications and significance of blockchain technology — great for complete beginners to get the core concepts before diving into VeChain specifics.

Overview of VeChain: what it is, goals, and where it sits in the blockchain ecosystem (dual-token model, enterprise focus). Good first read for new contributors/researchers.

Explains VeChain's EVM compatibility, why it matters, and implications for Solidity developers (porting, toolchain compatibility and caveats). Useful for developers familiar with Ethereum.

Covers standard smart contract operations (minting, transfers, locking etc.), plus safety patterns (access control, read-only queries) specific to VeChain. Good for developers to avoid basic mistakes.

Information on how to interact with contracts via the VeChain SDK (building clauses, transaction signing, etc.), which has security implications (e.g. properly building & signing, avoiding misuse of APIs).

Deep dive into programmable smart-contract wallets, ERC-4337-style workflows and how VeChain approaches account abstraction — useful to understand advanced UX/security patterns and new attack surface considerations.

Overview of VeChainThor’s consensus, PoA2.0 upgrade, and implications for protocol-level security (node operators, block validation, finality assumptions).

How governance decisions and authority node audits are structured in VeChain, plus transparency requirements for node operators.

Common pitfalls, Ethereum-compatibility caveats, and guidelines for safe contract development on VeChain.

Detailed definitions of the types of nodes (Authority Masternodes, Economic & X-Nodes, Full Nodes), duties, collateral, identity requirements, and rewards. Critical for understanding how node operators secure the network.

Explains available block explorers and how to use them to inspect blocks, transactions, addresses and contract activity — first stop for on-chain investigation.

Shows transaction structure, receipts, outputs and example SDK/JSON-API calls to fetch transaction details and receipts — essential for programmatic investigation and PoC reproduction.

Step-by-step guide to run a local Thor Solo Node (installation, CLI options, Docker, launching) — ideal for forking/sandbox testing and local PoC vulnerability testing.

Guide to create/configure a custom VeChainThor network for isolated testing, network parameter adjustments and reproducible PoCs. Use this to test edge-case attacks without touching main/testnet.

Defines a standard for personal message signing in VeChainThor, adapting Ethereum’s eth_sign to VeChain’s signature format.

Introduces designated gas payer functionality, allowing a transaction sender to specify another account to cover VTHO fees.

Proposes a simple self-signed certificate mechanism to let users attest to agreements or provide identity proofs via key signing.

Standardizes the interaction protocol between transaction senders and gas payers to ensure smooth fee delegation.

Proposes a protocol enhancement within the VeChain ecosystem.

Suggests improvements related to transaction processing or runtime behavior.

Introduces refinements for contract interfaces or developer APIs.

Outlines changes associated with consensus updates or node behavior.

Adds a standard for application-level or interface functionality.

Expands on EVM or transaction envelope enhancements for the network.

Extends smart contract functionality to improve developer and dApp capabilities.

Adjusts network economics with modifications to the gas fee mechanism.

Standardizes transaction type annotations and envelope formatting.

Establishes improvements to security protocols, client APIs, or data formats.

Defines a new extension or interface standard under VeChain’s roadmap initiatives.

Contains strategy and guidelines for ecosystem partnerships, sustainability, technical & operational partner collaboration, and how VeChain expects ecosystem participants to align with its goals (e.g. sustainability, real-world traceability). Useful for auditors / project leads to see ecosystem expectations.
