ConceptSLH-DSA
SPHINCS+
A hash-based post-quantum digital signature scheme whose security relies solely on the collision resistance of hash functions. It is highly conservative but produces very large signatures, making it suitable for firmware signing, root certificates, and other scenarios insensitive to performance but demanding extremely high security.

FIPS 205 (SLH-DSA) is derived from SPHINCS+ and is a hash-based signature scheme that can serve as a hedge against structural weaknesses in lattice assumptions.
