The Dogecoin Foundation has confirmed a successful experimental post-quantum secure transaction on the Dogecoin mainnet. Core developer Michin Lumin executed the test alongside the Foundation team. Foundation director Timothy Stebbing disclosed the milestone, adding that "experimentation continues." Software engineer Ed Tubbs publicly confirmed the result.
Google Raises the Alarm
In late March, Google researchers warned that future quantum computers could break certain blockchain cryptographic protections using fewer resources than previously estimated. The findings divided popular blockchain protocols into four risk categories. Dogecoin falls under the UTXO-based ledger category.
These networks allow users to shield assets behind cryptographic hashes using ephemeral public keys. This reduces exposure to at-rest attacks. The primary remaining risk is on-spend attacks, where a public key briefly becomes visible during a transaction. Address reuse worsens this exposure. Google identified post-quantum cryptography, or PQC, as the most practical defense available to the industry.
RE-EN and the Road Ahead
Dogecoin's quantum preparations began before Google's update. In January 2025, developers proposed integrating RE-EN, the Revolutionary Encryption Network, into Dogecoin's security infrastructure. RE-EN is designed to protect private keys, secure transactions, and resist quantum threats while remaining compatible with existing blockchain mechanisms.
The mainnet test does not mean Dogecoin is fully quantum-proof. Further testing, community consensus, and a formal upgrade process remain necessary. However, the successful transaction confirms that real progress is underway on one of crypto's most pressing long-term challenges.
At the time of writing, Dogecoin is trading at around $0.09250, up 0.91% in the last 24 hours.
