Integrating PQC at the Protocol Layer
Post‑Quantum Cryptography (PQC) is rapidly shifting from a theoretical concern to a mandatory global security requirement. As quantum computing advances, the cryptographic foundations that secure today’s digital systems, including blockchains, will become vulnerable. Algorithms such as RSA, Diffie‑Hellman, and elliptic‑curve cryptography can be broken by sufficiently powerful quantum machines running…
