Interactive Learning Update: Merkle Builder + Gas Fee Calculator
Get Started with Web3 has a new pair of hands-on learning components for beginners and builders.
What's new
- Merkle Tree Builder in the Bitcoin Cryptography lesson: type transactions, hash leaves, duplicate odd nodes, and inspect the Merkle root step by step.
- EIP-1559 Gas Fee Calculator in the Account Abstraction lesson: adjust gas limit, priority tip, max fee, and refresh live base-fee / ETH-USD estimates with visible fallback states.
- Both components are available in English and Chinese lessons and are covered by pure-function, component, and Markdown rendering tests.

Why this matters
The project is moving from static Web3 notes toward a bilingual, AI-native learning platform where learners can manipulate core concepts instead of only reading about them. AI agents can also discover the curriculum through llms.txt, the public content index, and the local read-only MCP server.
