Europol Addresses Quantum Computing Threats to Cryptocurrency Security
- Europol stated that cryptocurrencies will not collapse due to quantum computing.
- The main concern is the ownership of assets in wallets, especially from the “Satoshi era,” where public keys are exposed.
- Approximately 6.9 million bitcoin are held in addresses with visible public keys, raising security concerns.
- Exposed keys cannot be retroactively secured, leading to debates within the Bitcoin community about freezing BTC in vulnerable wallets.
- A study cited by Europol estimates that converting every unspent transaction output (UTXO) to a quantum-resistant format could take up to 300 days.
The distinction between hash functions and public-key cryptography is crucial, as hash functions used in blockchain history remain more resistant to quantum attacks than wallet controls. The potential vulnerability of early Bitcoin addresses poses significant risks as quantum computing advances.
With roughly 6.9 million bitcoin at risk due to exposed public keys, securing these assets has become a pressing issue for the cryptocurrency community.
