🐋 WHALE WATCH : BIP 361 proposes forcing Bitcoins migration to post quantum addresses before quantum computers can break ECDSA and Schnorr signatures. The mechanics: block new BTC transfers to exposed legacy addresses phase out old signature spends over a five year window and implement ZK proof recovery for anyone who misses the migration. Three steps hard deadline built in. Bitcoins cryptography isnt broken. But the do nothing forever era has a timer on it now. Migrate or get frozen out.(Whale Factor)
