# Beldex (BDX) Quantum Readiness Report

> Beldex has a QRI score of 3.5/100 and is assessed at Stage 1 (Quantum Risk Assessed) with medium evidence confidence.

Evaluation date: 2026-06-01. Review status: draft. Evaluated scope: Native BDX asset, Beldex blockchain, cross-chain bridge dependencies (BSC, Ethereum, Solana, Arbitrum, Base).

Beldex (BDX) is a Monero/CryptoNote‑fork privacy blockchain operating a PoS masternode consensus with classical elliptic curve cryptography across all critical layers. As of June 2026, spend authorization uses Ed25519/EdDSA, privacy is provided via ring signatures, stealth addresses, RingCT, and Bulletproofs++ — all of which rely on the hardness of the elliptic curve discrete logarithm problem and are fully vulnerable to Shor's algorithm. The project has acknowledged quantum risk in blog posts and roadmap items, with PQC research scheduled to begin Q2 2026, a lattice‑based cryptography POC planned for Q3 2026, and a quantum‑safe hardfork targeted for Q1 2027. However, no PQC implementation, prototype, testnet, technical specification, or migration tooling exists as of the evaluation date. The entire circulating supply, treasury holdings (~1.74B BDX ecosystem wallet, ~214.5M BDX seed/VC wallet), exchange balances, and cross‑chain bridged value remain exposed to long‑exposure quantum key‑recovery attacks with no migration, freeze, or deprecation mechanism in place. The project scores 3.5/100, placing it at Stage 1 (Quantum Risk Assessed) with a 'Roadmap Only' tag.
