a16z Crypto has released a new research lecture featuring Stanford cryptographer Dan Boneh, who discusses whether quantum computers could one day forge Bitcoin and Ethereum transaction signatures. The lecture also looks at what upgrades the two networks would need before that risk becomes real, and why blockchains may eventually move toward post-quantum cryptography. Bitcoin and Ethereum currently rely on elliptic curve digital signature algorithms to secure transactions. Boneh notes in the lecture that sufficiently powerful quantum computers could, in theory, break those signatures. As quantum computing continues to advance, the crypto industry is paying close attention to the migration path toward post-quantum security.
a16z Crypto has released a new research lecture that centers on a question now drawing close attention in the crypto industry: could quantum computers one day forge Bitcoin and Ethereum transaction signatures?
In the lecture, Stanford cryptographer Dan Boneh examines that possibility and discusses what would need to happen for the two networks to be upgraded before such a risk becomes real. Bitcoin and Ethereum currently use elliptic curve digital signature algorithms to secure transactions. In theory, a sufficiently powerful quantum computer could break those signatures.
The lecture also looks at why blockchains may eventually shift toward post-quantum cryptography. As quantum computing technology continues to develop, the crypto industry is watching the upgrade path closely.
