Bitcoin 'Doomsday Clock' sets quantum threat to BTC encryption at March 2028
- —Quantum Doomsday Clock sets the BTC break date at March 8, 2028
- —Threat comes from Shor's algorithm deriving private keys from public ones
- —Project forecasts 2029 for banking and the internet, 2030 for government systems
- —In 2026 the US Commerce Department pledged about $2 billion to quantum tech
Why it matters: The estimate flags a long-term risk to Bitcoin's ECDSA signatures and could accelerate demand for post-quantum cryptography in blockchain.
