# Aster (ASTER) Quantum Readiness Report > Aster has a QRI score of 0/100 and is assessed at Stage 1 (Quantum Risk Assessed) with very low evidence confidence. Evaluation date: 2026-08-17. Review status: draft. Evaluated scope: Native asset (ASTER) on Aster Chain L1 and multi-chain token representations. Aster (ASTER) is a privacy-focused L1 blockchain with a multi-chain token presence, launched in 2026. The project uses classical PoSA consensus, ECDSA/EdDSA spend authorization, and ZK-based privacy features with no evidence of post-quantum cryptography implementation, design, or roadmap. Core chain contracts are closed-source, preventing independent verification of cryptographic primitives, signature algorithms, or ZK proof systems. Validator-signed bridges connect Aster Chain to quantum-vulnerable host chains without restrictions. No audits, cryptographic inventories, threat models, or quantum-readiness plans have been published. The project receives a Stage 1 (Quantum Risk Assessed) rating with Very Low confidence due to the complete absence of post-quantum cryptography evidence and the closed-source nature of critical implementations. All critical layers (spend authorization, consensus, privacy, bridges) remain quantum-vulnerable by default. ## Core resources - [Aster QRI report](https://qrindex.org/projects/aster-2/): Human-readable assessment with score, stage, evidence, blockers, risks, and assurance notes. - [Aster structured report data](https://qrindex.org/projects/aster-2/report.json): Complete report as JSON for deterministic machine processing. - [QRI methodology](https://qrindex.org/methodology/): Scoring model, evidence handling, readiness stages, confidence, assurance, and report status. - [All QRI project reports](https://qrindex.org/llms.txt): Score-ranked index of every published project assessment. - [Aster official website](https://www.coingecko.com/en/coins/aster-2): Project-maintained website. ## Evidence sources - [Evidence source 1](): Public source cited by the Aster QRI assessment. - [Evidence source 2](): Public source cited by the Aster QRI assessment.
