SorachanCoin (IUEC)

Consensus: Quantum-Vulnerable
Why this rating. Judgment call: hybrid scrypt proof-of-work and proof-of-stake chain; stake blocks carry classical signatures and no post-quantum block signing is published. The roadmap lists a review in 2026 and rollout to 2028.
Transactions: Quantum-Vulnerable
Why this rating. Judgment call: opt-in QAI addresses add a hash-based signature, but the verifier compares only 128 bytes, about 4 bits of the message hash, so it gives no real post-quantum protection.
Algorithms: None listed
Website: Website
Source: Source
Note and links: IUEC chain, not SORA Nexus
