Google will implement post-quantum encryption by 2029.
Nic Carter, a partner at Castle Island Ventures, warned that elliptic curve cryptography will soon become obsolete. He predicts this will happen within the next 3-10 years, and the industry must acknowledge this reality.

The investor believes blockchain developers urgently need to enhance the security and adaptability of network algorithms:
“The only thing that matters right now is how quickly developers understand the need for cryptographic flexibility.”
As a positive example, he pointed to Ethereum. The project team presented a roadmap for protecting the network from quantum computers, making this task a strategic priority. Developers have integrated new algorithms into their current plans and addressed key community questions.
Carter believes the Ethereum ecosystem shows “more action and less fear.” In contrast, he criticized the Bitcoin development team's approach to the looming threat as the least effective.
Google's Preparation for the Quantum Era
Meanwhile, Google has revealed its plans for transitioning to post-quantum cryptography. The company aims to fully implement new algorithms by 2029.
According to the corporation, future quantum computers pose a threat to current encryption standards and digital signatures. To prevent potential breaches, Google has updated its corporate threat model, focusing on transitioning authentication services to new protocols.
The post-quantum protection for digital signatures (ML-DSA) is set to be added to Android 17. Similar solutions have already been implemented in the Chrome browser and the company's cloud services.
As a reminder, on March 19, the platform BTQ Technologies launched a Bitcoin testnet with quantum protection.
