Decred

Consensus: Quantum-Vulnerable
Why this rating. Hybrid proof-of-work and proof-of-stake: ticket holders vote on blocks with elliptic-curve signatures. No post-quantum scheme protects those votes. Searches of dcrd, the DCPs and Politeia found no such proposal.
Transactions: Quantum-Vulnerable
Why this rating. Spends use secp256k1 ECDSA, with Schnorr and Ed25519 as options. Release 1.7 added post-quantum key exchange to the mixing protocol, which protects mix privacy but not spend signatures. No post-quantum signature work found.
Algorithms: None listed
Website: Website
Source: Source
Note and links: PQ only in mixing
