Circle emphasized that quantum resilience has to show up in the infrastructure.

Google warned quantum computers could break Bitcoin cryptography in nine minutes.

Active addresses must migrate before Q-Day because their public keys have been exposed.

Circle plans a multi-phase approach starting with quantum-resistant wallets.

A privacy layer will shield balances and transactions after mainnet launch.

Quantum solutions will extend to validators and off-chain infrastructure.

The phased strategy allows users to migrate at their own pace.

Circle characterized the campaign as a preemptive measure.

Google and Caltech researchers warned powerful quantum computers may arrive sooner than expected.

“Circle, the issuer of stablecoins, has published a post-quantum security roadmap for its Layer 1 blockchain Arc, with the goal of implementing solutions across all layers of the network's technology stack”

Algorand was identified as the most quantum-ready blockchain.

Ethereum and Solana are actively developing solutions.

Bitcoin lacks a quantum-resistance roadmap.

Circle is the first major stablecoin to address quantum threats.

Circle warned about harvest now, decrypt later attacks.

Wallets with previously exposed public keys face particular risk.

Inaction is risky and this conversation cannot wait.

Functional quantum computers may require less computing power than earlier estimates.
