Yes. Mastering Bitcoin and Mastering Ethereum are open source on GitHub, and Princeton's Bitcoin and Cryptocurrency Technologies is free online.

How can I learn smart contract security?

Practise with Ethernaut and Damn Vulnerable DeFi, study the SWC Registry, and use static analysis tools listed on the Blockchain Tools page.

Where can I follow blockchain news?

CoinDesk, Cointelegraph, Decrypt and Bankless cover the industry, and L2BEAT tracks Ethereum scaling networks.
