Blockchain Security Guarantees and Exploits
summary
Scans of 34 billion keys produce 732 private keys tied to 57,000 on‑chain transactions, but no large untouched balances; one automated actor consolidates loot exceeding $100 million by instantly sweeping weak wallets, and an address derived from a null public key holds about 815 ETH lost to error. Paper wallet toolkits are shown generating predictable seeds that stole millions, and IOTA seed tampering led to >$10M thefts, proving bad entropy and supply chain tampering matter.
