Bio

Silur started his career as a pentester and hacker at a really young age, with a great affinity to cryptography and higher mathematics. Having a good prior understanding in cryptocurrencies when the industry boomed in 2016, he gained an advantage as an early industry specialist, doing work for the Ethereum foundation until 2018. In 2019 he designed a cipher that entered the NIST Lightweight Encryption Standard competition. Consequently, he proved himself in designing and implementing blockchains from scratch as the co-founder of QANPlatform and as an early partner of CasperLabs. Having built dozens of dApps, protocols and full chains from both mass-market and government clients, Silur is also a co-organizer of the largest Capture the flag event on the planet, in which he challenges the best hackers in the world to break blockchain systems and reproduce historical cryptocurrency hacks. Silur is also a member of the Wigner's research centre of physics where he specializes on quantum computation and post-quantum cryptography. He took a place on the Forbes 30 under 30 list for his achievments in cybersecurity and web3.

I want this!

My own open-source work and research projects

Code

BZTE

The Baek-Zhang threshold cryptosystem implemented in rust
Useful for on-chain randomness and MPC.

https://github.com/Silur/bzte

ZeroTwo

Zero-knowledge 2FA with the strength of a klaxxosaur.

https://github.com/Silur/ZeroTwo

Stegan.io

F5 steganography in your browser
Hide hidden and optionally encrypted data into seemingly normal images
https://stegan.io/

https://github.com/silur/steganio

JSON-deepcrypt

A tool to recursively encrypt and optionally MAC specified fields of JSON data based on jq-like schemas. The codebase was originally intended to ease pinning of JSON-based stuff on blockchain but found other use cases. It uses OpenPGP.js under the hood

https://github.com/silur/json-deepcrypt

Vecna

Fiat-shamir secret sharing in OCaml. Named after the D&D lich keeping hidden knowledge and secrets :)

https://github.com/silur/vecna

Research

Post-quantum verifiable random functions from ring signatures

A source of verifiable randomness using RLWE as trapdoor and some reconciliation information for proofs.
https://eprint.iacr.org/2018/1231

Circuit friendly, post-quantum dynamic accumulators from RingSIS with logarithmic prover time

ZeroKnowledge-friendly set-membership proofs using RingSIS, where verifiers can be efficiently implemented on 16-bit hardware and even smart contracts.

Testimonials

His passion and dedication are evident in every project he undertakes. At Altcoinist, he showcased remarkable flexibility, adapting seamlessly to our business shifts. His innovative approach consistently delivered creative solutions, making him an invaluable asset to our team. Highly recommended for any development endeavor.

Konstantin Sebeo

Altcoinist.com Co-Founder

His expertise and experience has taken us to the next level! Though he is recognised as a state of the art blockchain architect, he remains humble. Silur was also involved in helping with our marketing, making use of his considerable experience and amazing networking skills.

Gabor Retfalvi

NextEarth

From the beginning he helps as an independent expert and performed lots of special API tests and specific attacks to measure our platform's performance caps endpoint-by-endpoint. Our platform as custodial service store signifiant amounts of customer's money, so the data protection and penetration tests are essential to keep up our services. This is why we appreciate Silur's helping hand!

Csaba Csabai

Income Locker

He provided us proven methods and guidelines not only from a technical security perspective but made sure everything is game-theoretically correct for the community so there's no selfish, adversarial or unfair outcome for any type of user.

Johann Polecsak

Netflow

We were already familiar with some of his work, but seeing him working on something that is close to us, was a different level of experience.
