Hedera is mentioned there. It is worth a read.
[https://quantumtracker.org/#report/blockchains/hedera](https://quantumtracker.org/#report/blockchains/hedera)
>Hedera uses Hashgraph consensus (asynchronous BFT) rather than a traditional blockchain. All user transactions and consensus events are signed with Ed25519 or ECDSA secp256k1 — both vulnerable to Shor's algorithm. Hedera was architecturally designed with pluggable cryptography, meaning signature algorithm swaps do not require deep protocol rewrites. The network uses SHA-384 hashing throughout (events, certificates, state proofs), which is quantum-resistant for preimage and collision attacks. However, no PQC signature algorithms have been implemented in the core protocol, and no formal migration timeline has been published. A SEALSQ partnership for quantum-safe hardware (QS7001 chips) was announced in late 2024, signaling infrastructure-level interest but not a protocol-level commitment.
