Google's new quantum paper feels like a wake-up call for Crypto.
The headline is not that Bitcoin or Ethereum are broken today. It is that the resource estimate for attacking the elliptic-curve cryptography behind them has dropped sharply, which makes the threat feel much less theoretical.
That puts exposed public keys, address reuse, old wallets, and slow post-quantum migration plans under a much brighter spotlight.
Is your chain preparing for a post-quantum future, or just hoping quantum arrives late?
