Grayscale Research: Social Barrier in Bitcoin Quantum Threat

Grayscale Research Head Zach Pandl emphasized that the biggest challenge for Bitcoin (BTC) against the quantum computer threat is not technical but social. Google’s article published on March 30 claimed that quantum computers could break BTC cryptography with fewer resources. According to Pandl, BTC is more resilient than other cryptocurrencies thanks to its UTXO model, proof-of-work consensus, and lack of smart contracts; however, some address types remain vulnerable.

The BTC community should take action regarding the dormant coins in old P2PK addresses holding approximately 1.7 million BTC (including Satoshi’s estimated 1 million BTC, currently worth 68 billion dollars). Options: burn the coins, limit the spending rate from vulnerable addresses, or wait. Pandl highlighted the difficulty of reaching agreement by recalling the controversial history of protocol changes (e.g., 2023 Ordinals crisis). The threat is not yet present, but transitioning to post-quantum cryptography is essential. Solana and XRP Ledger are conducting tests, and the Ethereum Foundation announced a roadmap in February. Investors can stay calm by checking the BTC detailed analysis.
