Junior Panchu has arrived.
Circle just designed @Arc to be quantum-resistant from the very first block - and most people building onchain haven't fully processed what that means.
Every wallet, every transaction, every smart contract on every EVM chain today is secured by elliptic curve cryptography. Shor's algorithm, running on a sufficiently powerful quantum computer, breaks all of it.
The threat isn't waiting for Q-Day to start. Harvest-now, decrypt-later is already live. Adversaries collect encrypted onchain data today and hold it until quantum hardware catches up. Every public key ever exposed on any chain is already in that exposure window.
NIST finalized the post-quantum standards in August 2024 - ML-KEM (FIPS 203), ML-DSA (FIPS 204), SLH-DSA (FIPS 205). The industry migration deadline is 2030. The clock is running.
What @circle built into Arc is the only answer that makes architectural sense: quantum-secure signatures live at mainnet launch, from block one. Not retrofitted. Not a future hard fork. ML-DSA, CRYSTALS-Dilithium, Falcon - built in from genesis, opt-in, no forced migration, no network reset.
The rollout covers the full stack. Wallet signatures at launch. Private VM layer next - confidential transfers shielded, public keys wrapped in symmetric encryption. Then infrastructure: TLS 1.3 with X25519MLKEM768 hybrid key exchange, HSMs upgraded. Finally validator authentication - moved only after performance testing confirms sub-second finality holds.
Wrote a full breakdown in the Arc House India chapter - why this architecture matters, what the real tradeoffs are, and why this is directly relevant to anyone building payment infrastructure in India right now.
