Circle’s plan to make Arc quantum-resistant comes amid increasing fears that “Q-Day” may come sooner than anticipated.
Stablecoin issuer Circle has released a post-quantum security roadmap for its layer-1 blockchain, Arc, aiming to implement solutions across all layers of the network’s tech stack.
Circle said on Thursday that it is planning a phased implementation, starting with quantum-proof wallets and signatures when Arc launches on mainnet. This feature will be opt-in, the company noted, while adding that solutions at the validator level and surrounding infrastructure will be implemented later on.
“Quantum resilience cannot live only in research papers, exploratory pilots, or distant roadmap slides. It has to show up in the infrastructure,” Circle said.
