CRYSTALS-Dilithium is a digital signature algorithm designed to resist attacks from quantum computers, built on the hardness of lattice-based mathematical problems rather than the elliptic curve math that today's ECDSA relies on. It is one of the algorithms standardized by NIST for post-quantum cryptography and is emerging as a candidate for securing blockchain transactions once large-scale quantum computers become a practical threat.
On this page you'll find articles on how Dilithium works, its trade-offs against ECDSA in signature size and performance, NIST's post-quantum standardization process, and what migrating blockchain infrastructure to quantum-resistant signatures will require.
Compare ECDSA and CRYSTALS-Dilithium, understand why post-quantum digital signatures matter, and learn how blockchain infrastructure will evolve in the quantum computing era.
