🚨Migration of Bitcoin and Ethereum to Quantum Secure Blockchains:
📍Is the #Crypto world ready for Quantum D-Day?
Or are we sleepwalking into a Trillion dollar catastrophe?
🚀 NEW Ground-Breaking Research from BBA Fellow, Dr. Rob Campbell FBBA.
➡️ KEY HIGHLIGHTS:
⏩ Moving to post-quantum cryptography isn’t an upgrade – it’s a defensive downgrade:
Current PQC options mean accepting major costs now (around 50% capacity loss, higher latency and fees, heavier nodes) in return for protection against a future, uncertain quantum threat.
⏩ We’re benchmarking the wrong thing:
Almost all performance data comes from permissioned prototypes (e.g. enterprise/consortium chains), not global permissionless systems like Bitcoin and Ethereum – a critical methodological gap for trillion-dollar networks.
⏩ Quantum Threat Timeline is brutally tight:
Breaking secp256k1 requires 2,100–2,400 logical qubits (down from earlier estimates due to algorithmic improvements), with current systems at ~100 qubits, placing the threat 10-15 years away—but governance delays could match or exceed this window.
✅ The SOLUTION:
⏩ Crypto-agility is the only sensible path forward:
Instead of hard-wiring one “quantum-safe” scheme, research proposes a #HYBRID designs and crypto-agile protocols - so Bitcoin/Ethereum can swap algorithms if (or when) today’s PQC breaks – and AVOID a chaotic, crisis-driven upgrade later.
