Crypto agility is survival
Identity anchored to a DID, not to an algorithm
Systems must adapt to new cryptography without disruption — or they will fail in transition.
Understand what changes - and what breaks.
Six short explainers. Everything you need before Q-Day.
02 / The role of DIDs as anchors
Approximate sector exposure
Crypto agility is the ability to swap cryptographic algorithms in a running system without disrupting identity, integrations, or partners. Business Wallet achieves this by anchoring who you are (your DID) separately from how you sign (your keys).
The NIST-finalized standards CRYSTALS-Kyber (key exchange, now ML-KEM) and CRYSTALS-Dilithium (signatures, now ML-DSA) are the globally recognized post-quantum algorithms. Business Wallet lets you adopt them incrementally — no big-bang migration required.
