Shinobi: About 7 million BTC could be exposed if quantum threat materializes
- —About 7 million BTC are vulnerable due to exposed public keys in scripts and address reuse
- —Of that, roughly 3.3 million BTC are actively traded and about 1 million BTC are Satoshi-era rewards
- —Shinobi advises against address reuse and recommends hash-based address types other than Taproot
- —Blockstream researchers are close to a basic quantum-safe signature scheme
Why it matters: The quantum threat covers a large share of BTC supply, and migrating to new signatures will require action from holders themselves.
