Dogecoin Completes Mainnet Post-Quantum Transaction Test

Dogecoin developers, through the Dogecoin Foundation, have completed the first experimental post-quantum secure transaction on the Dogecoin mainnet. Core developer Michin Lumin executed the test with Foundation director Timothy Stebbing, and engineer Ed Tubbs publicly confirmed the result. The Foundation said “experimentation continues,” adding that more testing, community consensus, and a formal upgrade process are still required. The milestone follows Google’s warning that quantum computers could break today’s blockchain cryptography sooner than expected. Google grouped blockchain protections by quantum risk and placed UTXO-based ledgers (including Dogecoin) in a model that can reduce “at-rest” exposure using ephemeral public keys, but still faces on-spend risk when public keys briefly appear—especially with address reuse. Google also points to post-quantum cryptography (PQC) as the most practical direction. Earlier, in January 2025, the Dogecoin team proposed integrating RE-EN (Revolutionary Encryption Network) to better protect private keys and transactions while aiming to stay compatible with existing blockchain mechanisms. For DOGE traders, this is a tech-risks narrative catalyst: Dogecoin is moving from discussion to mainnet experimentation on post-quantum security, but timelines for full quantum-grade protection remain uncertain. DOGE was around $0.09250 at the time of the report, up about 0.91% in 24 hours.
