Pearl

Consensus: No Signatures / Quantum Resistant
Why this rating. Proof-of-useful-work mining: blocks are found by matrix-multiplication work, so consensus needs no digital signatures.
Transactions: Post-Quantum
Why this rating. Judgment call: the node deploys OP_CHECKXMSSSIG (XMSS) for Taproot script-path spends, and the wallet derives such addresses. The Schnorr key path still exists, so protection depends on wallet use.
Algorithms: XMSS

Source: Source
Note and links: XMSS spend path is optional
