" summary

Covers concrete failures: Solidity smart contracts with mutable deployment mistakes that allow ownership takeover of a shared library and result in 300 million locked in Parity wallets, and a classic DAO reentrancy drain of $53M where withdraw pays before updating balances. Shows the exact buggy pattern and the simple fix (update balance before payout), explains how immutability forces forks (Ethereum vs Ethereum Classic), and contrasts modular library reuse with the safer monolithic approach.
