From the project xxx:
“1.1.1.1 now validates DNSSEC signatures made with ML-DSA-44, a post-quantum signature algorithm standardized by the National Institute of Standards and Technology (NIST). This is a first step toward preparing DNSSEC for a future in which today’s signature algorithms are no longer secure.

Cloudflare plans to achieve full post-quantum security by 2029. Much of the work so far has focused on TLS, but public-key cryptography is used in many other systems, including DNSSEC. […]”
