Bitcoin has roughly three to five years to prepare for potential quantum computing threats, according to a research report from Bernstein.
The analysts described quantum computing as a “manageable upgrade cycle” rather than an existential risk, despite recent breakthroughs such as research from Google showing reduced resources needed to break encryption.
“Quantum computing is a manageable upgrade cycle rather than an existential risk,”
The Bernstein analysts said in the report.
The firm noted that practical quantum computers capable of breaking Bitcoin’s cryptography remain years away due to technical complexity and cost barriers.
Vulnerabilities are concentrated in older Bitcoin wallets, particularly those that reuse public keys or use legacy address formats where keys are already exposed.
Newer wallet standards and best practices, including avoiding address reuse, significantly reduce exposure to potential quantum attacks.
Bernstein added that Bitcoin’s mining algorithm is not meaningfully at risk, and that the network’s open-source developer community is expected to coordinate any necessary upgrades.
At the time of reporting, Bitcoin price was $70,875.91.
