Gartner warns quantum computing could break Bitcoin's cryptography by 2030
- —Gartner: public-key cryptography may be unsafe by 2030
- —BIP-360 removes Taproot key-path but leaves mempool exposure
- —NIST post-quantum signatures are 38-123x larger, TPS would fall below 1
- —SHRINCS signatures range from 548 to 4,619 bytes and remain immature
Why it matters: Bitcoin needs consensus on quantum-resistant signatures before 2030, or legacy addresses and network trust could be at risk.
