About Dmytró “Matt” Kondratiuk

Software Engineer / Security Researcher with more than a decade of experience in cryptography, distributed systems and financial‑tech. Author of several peer‑reviewed papers on random‑number generation and blockchain security, and the creator of the Mega‑Peers Bitcoin Oracle.

I have worked closely with Ledger, the Bitcoin Foundation and Cardano on hardware‑wallet hardening, secure‑enclave design and independent audit tooling. My research is driven by a single principle – *your private keys must remain private*.

Key Benefits

Independent Early‑Warning

Runs locally on a trusted machine and signals any entropy‑related weakness before a wallet is used.

Hardware‑Wallet Friendly

Supports Ledger, Trezor and emerging secure‑enclave devices. Plug‑in architecture lets new wallets integrate with a single line of code.

Universal Entropy Protection

The same TRNG‑audit engine that safeguards hardware wallets can be applied to any system that depends on randomness. By analysing the entropy source you can detect weak‑randomness attacks on:

  • 🔐 TLS/SSL certificates – stop forged HTTPS keys.
  • 🏦 Traditional banking systems – protect transaction‑signing RNGs.
  • 🪙 Pass‑keys & password managers – guarantee truly random master‑secrets.
  • 🆔 Government‑issued IDs (e‑IDs, digital and chipped passports).
  • 🚀 Military command & control (e.g., nuclear‑launch code generation).
In short, any critical workflow that relies on a **True Random Number Generator** can be audited and hardened with the Doomsday Explorer platform.

Open‑Source & Auditable

Full source code on GitHub, signed releases, and a transparent profit‑sharing model for contributors.

Trusted Reviews

“The most thorough entropy‑audit I’ve seen. A must‑have for anyone who treats their private keys as sacred.”

Joseph K., CryptoSec Labs

“Our partnership with the Explorer platform gave us early insight into hardware‑wallet weaknesses that would otherwise have gone unnoticed.”

Anna L., Ledger R&D

“A critical defensive layer for the entire Cardano ecosystem – proof that open‑source security works.”

Charles H, Cardano Foundation

“Matt is a reliable, smart, and extremely skill‑full engineer. I have repeatedly relied on his technical judgment and integrity during critical projects, and his work always exceeds expectations”
