A fresh debate over Dogecoin's long-term security model erupted this week after Dogecoin Foundation developer Paulo Vidal questioned whether the meme coin still relies too heavily on Litecoin for its survival. Vidal asked pointedly: "If Litecoin stopped operating tomorrow, what would happen to Dogecoin's security?" and wondered if miners are incentivized enough by Litecoin rewards alone or whether the extra payouts from Dogecoin and other AuxPoW networks play a critical role.
The exchange drew a sharp retort from Dogecoin co-founder Billy Markus, known on X as Shibetoshi Nakamoto. Markus urged critics to "read Satoshi's white paper" and stressed that miners work purely for reward, not out of loyalty to any one chain. He dismissed Vidal's concerns as invalid, insisting that Dogecoin's merge-mining setup—Auxiliary Proof of Work (AuxPoW)—is both functional and sufficient.
David Schwartz, Director of Projects and Strategic Partnerships at the Litecoin Foundation, sided with Markus. He argued that merge mining remains the best path forward: "Honestly, even if Dogecoin did not have these benefits to Litecoin, I would still advocate that it stay merge mined to Litecoin because it was the right thing to do back then and it's the right thing to do now." Markus echoed that sentiment, calling any move away from merge mining "dumb and pointless." The debate underscores a wider community rift over Dogecoin's technical roadmap, though no immediate changes have been proposed.
