Silur.dev

Hello, I am Silur 🦊,

Your dedicated consultant and developer specializing in the field of crypto and blockchain. From conceptualization to execution, I offer comprehensive services that encompass tokenomics, whitepaper formatting, contract and web development, security auditing, listing, and risk management.

With me, you can rest assured that your focus will be on outcomes and objectives rather than billing for tasks and hours. My designs and implementations adhere to industry standards such as SOC2, NIST SP-800, and C4 Standards. Should you have any doubts, rest assured that these compliance measures are verified during an additional audit process.

Bio

I started my career at a young age, delving into the world of pentesting and hacking, driven by a fascination for cryptography and advanced mathematics. As the cryptocurrency industry began to boom in 2016, I leveraged my expertise and started contributing to the Ethereum Foundation until 2018 as well as participated as a researcher for the Monero Research Labs.

In 2019, I crafted a cipher that earned recognition in the NIST Lightweight Encryption Standard competition. I later co-founded QANPlatform and became an early partner of CasperLabs, undertaking the design and implementation of blockchains from the ground up.

Over the years, I've successfully developed numerous dApps, protocols, and complete blockchain networks, catering to a diverse clientele ranging from mass-market to government entities.

Beyond my development work, I also co-organize the world's largest Capture the Flag event, where I challenge the most skilled hackers worldwide to test and breach blockchain systems while recreating historical cryptocurrency hacks. Additionally, I'm a member of the Wigner's Research Centre of Physics, specializing in quantum computation and post-quantum cryptography. My contributions and work have earned me a place on the Forbes 30 Under 30 list in 2022 in recognition of my achievements in the fields of cybersecurity and web3. I've lately focused on Artificial Intelligence through Defaince, a project I recently co-founded.

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.

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.
