Arweave

Consensus: Quantum-Vulnerable
Why this rating. Judgment call: mining uses proof-of-access with RandomX, but each block carries a signature by the miner's reward key, checked in ar_block.erl (RSA, ECDSA or Ed25519). No post-quantum work appears in the repository.
Transactions: Quantum-Vulnerable
Why this rating. Wallets sign with RSA-PSS, secp256k1 ECDSA or Ed25519 (ar_wallet.erl). Searches of the ArweaveTeam repository and web found no post-quantum signature work.
Algorithms: None listed
Website: Website
Source: Source
Note and links: No public quantum plan found
