Dogecoin developers are thinking about how to prepare against the quantum threat. A Dogecoin Foundation developer said that progress had been made on flagging post-quantum transactions. Ed Tubbs, Dogecoin Foundation developer, wrote on X on Friday that the teams are working on ways to send quantum-proof transactions on the second biggest proof of work blockchain. “We’re still in the early experimental phase, but it’s exciting to see real post-quantum proofs appearing on mainnet,” wrote Tubbs.
Tubbs said that the latest advancement will allow users of the Dogecoin network to send a quantum-safe proof transaction alongside a normal Dogecoin one. The method works by embedding a compact cryptographic fingerprint — known as a commitment — into a standard Dogecoin transaction using the network’s existing OP_RETURN field, which can store small amounts of arbitrary data. A second transaction then reveals the full post-quantum signature on-chain, with the small amount of DOGE used to carry it returned to the sender. Bitcoin needs a quantum upgrade. So why isn’t it happening?
While still in an experimental phase, the work shows, according to Tubbs, that eventually users of the network will be able to send Dogecoin transactions and flag that they are quantum resistant. Still, the crypto network is still not protected against the threat of quantum computers and the blockchain would still need to upgrade to be quantum resistant. Hayk Tepanyan, founder of BlueQubit, a quantum computing software developer, told DL News that cryptographically relevant quantum computers could be a reality in just three to five years. Still, the industry is torn on how best blockchains should prepare.
