A Google whitepaper sets a 2029 target for migrating away from today’s cryptography, warning that quantum advances could undermine widely used schemes.

Drift Protocol said a Solana-based perp DEX was exploited on April 1, 2026, with about $286 million removed in roughly 12 minutes after attackers prepared fake collateral and used pre-signed admin transactions.
