Benchmark analysts assert that the threat of quantum computing to Bitcoin is overstated and manageable, emphasizing a long-term perspective.
In a recent report, Benchmark analysts have characterized the quantum threat to Bitcoin as manageable and a long-term concern. Experts are advising against panic, emphasizing that real attacks on Bitcoin's cryptographic system are still decades away.
Researcher Mark Palmer acknowledged the theoretical risks posed by quantum computing, particularly the ability to compute private keys from public data. However, he noted that this threat is limited to Bitcoin held in addresses with exposed public keys.
Vulnerability Assessment
Benchmark's analysis estimates that between 1 to 2 million BTC are currently at risk, particularly those linked to reused addresses or wallets dating back to Satoshi Nakamoto's era. In contrast, K33 researcher Vetle Lunde suggested that the number could be as high as 6.8 million BTC. He emphasized the importance of developer collaboration over panic selling.
Predictions about when the quantum threat will become significant vary among experts:
- Venture capitalist Chamath Palihapitiya indicated that risks might emerge in the next 2-5 years;
- Conversely, cryptographer Adam Back argued that serious threats could be 20-40 years away.
Benchmark analysts also dismissed claims that Bitcoin's infrastructure is too rigid, highlighting successful updates like the Taproot soft fork and expressing confidence in the network's ability to adapt to quantum resistance.
Industry Readiness
Key players in the crypto space are proactively preparing for a post-quantum landscape. The Ethereum Foundation has formed a security team and allocated $1 million for research, while Coinbase has established an advisory board to tackle quantum-related risks.
Investor sentiment remains cautious. Notably, Jefferies strategist Christopher Wood has excluded Bitcoin from his model portfolio due to concerns over quantum technologies. Additionally, analyst James Checkonchain pointed out that the current weakness of Bitcoin is primarily driven by long-term holders selling, rather than fears about its future viability.
