What We Built Into the Protocol (And Why It Matters)

By Dr Krzysztof Urbanowicz, Founder of QWID There’s a philosophy in blockchain design that says: keep the base layer minimal and push everything else to smart contracts. Ethereum pioneered this approach, and it’s produced extraordinary innovation. It has also produced extraordinary failure — billions lost to smart contract bugs, oracle manipulation, bridge exploits, and gas …

The Math Behind QWID: Why Two Algorithms Are Better Than One

By Dr Krzysztof Urbanowicz, Founder of QWID When we designed QWID’s cryptographic layer, we made a decision that some considered excessive: every transaction is secured by not one but two post-quantum signature algorithms, each built on entirely different mathematics. In this article, I want to explain why that choice is not excessive at all — it’s the …

Why Post-Quantum Cryptography Matters Now — Not Later

By Dr Krzysztof Urbanowicz, Founder of QWID If you hold cryptocurrency today, your private keys are protected by a mathematical assumption: that certain problems are too hard for any computer to solve in a reasonable time. That assumption has served us well for decades. But it has an expiration date — and that date is …
