The quantum threat to Bitcoin may be more social than technical, according to Grayscale’s head of research, Zach Pandl.
A recent Google paper suggested quantum computers could break Bitcoin’s cryptography with far less power than previously believed.
However, Pandl emphasized that Bitcoin's architecture-using UTXO model and proof-of-work-presents lower risk compared to other cryptos. Still, the main hurdle lies in community consensus.
About 1.7 million BTC, including Satoshi’s stash, are at risk due to lost private keys in early P2PK addresses.
The Bitcoin community must decide whether to burn these coins, slow their release, or take no action.
Pandl noted that while no immediate threat exists, blockchain adoption of post-quantum cryptography should begin now.
Platforms like Solana and the XRP Ledger are already testing this tech. Ethereum has also published a quantum resistance roadmap.
Investors should not panic, but preparation is vital.
In our view, there is no security threat to public blockchains from quantum computers today.
