What are Quantum-Resistant Blockchains?

Too Long; Didn't Read

Quantum-resistant blockchains refer to cryptographic algorithms that are resistant to attacks using quantum computers. Current public-key algorithms depend on complexity of solving the discrete log and factorization problem of large prime numbers. NIST's post-quantum cryptography (PQC) standardization process, NIST standards will be available by 2024. A standard of algorithms for digital signatures is likely to emerge to replace the signatures specified in FIPS 186-4 (e.g., DSA, and ECDSA)
