Topic objects - The Blockchain Library

Topic object

Each major subject has a stable id that should remain consistent even when page titles, descriptions, or URLs evolve.

{
  "id": "smart-contracts",
  "title": "Smart Contracts",
  "slug": "smart-contracts",
  "summary": "Programs deployed to blockchain-compatible execution environments...",
  "level": "intermediate",
  "hub": "/topics/smart-contracts",
  "primaryPage": "/learn/foundations/smart-contracts",
  "relatedTopics": ["blockchain", "wallets-security", "defi"],
  "tags": ["smart-contracts", "execution", "dapps"]
}

Design rules

IDs use lowercase kebab-case.
IDs are stable identifiers, not display labels.
A topic should have one canonical hub.
Relationships use topic IDs rather than copied titles.
Resource arrays contain public documentation paths.
Tags support future search, filtering, and classification.

Current topic set

The initial engine includes Blockchain, Cryptocurrency, Wallets & Security, Smart Contracts, DeFi, Web3, Blockchain Infrastructure, Enterprise Blockchain, and AI + Blockchain.
