A draft BIP is available for public review within the libdogecoin repository.
Google projects commercial quantum computers before 2030, shortening the transition time.
Ed Tubbs, senior software engineer at the Dogecoin Foundation, announced on April 10 that his team is conducting experiments on the mainnet of Dogecoin to attach post-quantum signatures to ordinary transactions. The mechanism uses Falcon-512, a quantum computer-resistant signature algorithm, and operates without modifying the network’s base protocol.
The development is part of what could be the first documented post-quantum protection initiative on the Dogecoin network. Until now, no formal effort in this direction had reached the mainnet. Work is progressing within the libdogecoin repository, where testing tools and a draft BIP are already available (Dogecoin Improvement Proposal) ready for public review, according to Tubbs pointed out..
The mechanism operates in two transactions. The first, identified as TX_C, attaches a fingerprint of the quantum signature to a normal DOGE shipment and sets aside 1 DOGE as the bearer. The second, identified as TX_R, uses that DOGE to post the full signature to the chain and returns it to the original addressless the commission.
Tubbs clarified that the second transaction step is completely optional. The former alone is sufficient for most tests, reducing friction for those who want to experiment with the system without incurring significant additional costs.
The pressure of the quantum horizon
The context of this proposed improvement is not minor. Google said it was convinced that commercially relevant quantum computers will be available before the end of this decade.
That projection has direct implications for the ecosystem: the cryptography that protects bitcoin wallets and other cryptocurrencies is based on mathematical problems that classical computers would take thousands of years to solve, but a sufficiently powerful quantum computer could do so in hours or minutes.
Google’s advance does not represent an immediate threat, but it does shorten the time available for the ecosystem to make that transition. In this scenario, initiatives like Tubbs’ take on practical relevance: unlike proposals that require protocol changes, this approach allows testing post-quantum infrastructure on an optional basis and without interrupting the normal operation of the network.
The team is in an early experimental phase. With a draft BIP available to the community, the next step will depend on consensus between developers and network users.
