Google flags quantum threat to Bitcoin, eyes 2029 post-quantum shift

TL;DR Summary
Google Research warns that the quantum resources needed to break ECDLP-256 have fallen roughly 20-fold, potentially enabling on-spend attacks against Bitcoin within its 10-minute block window and prompting a 2029 migration to post-quantum cryptography; the industry, including Coinbase and the Ethereum Foundation, is coordinating on the transition, though the risk remains years away.
