What if quantum readiness requires changing the architecture, not just the algorithm? Randomness is another interesting part of @tezos’ Quantumnet experiment. Blockchain consensus needs mechanisms to determine participation and selection fairly. Historically, Tezos has used verifiable randomness involving a Verifiable Delay Function (VDF). Quantumnet explores a different approach: Smooth Weighted Round Robin (SWRR). Why does this matter? 🔸Identify the dependency: Understand which cryptographic mechanisms could become vulnerable. 🔸Question the design: Does the existing architecture still make sense? 🔸Explore alternatives: Consider different mechanisms rather than simply replacing one algorithm with another. 🔸Test the new approach: Evaluate its security, fairness and performance. The bigger lesson? Post-quantum readiness isn’t always about upgrading cryptography. Sometimes, it’s about redesigning the system around its vulnerable dependencies. That’s the kind of architectural thinking that makes Tezos’ Quantumnet experiment worth following. One person worth checking and following about this is @chrispinnock Should blockchains prioritise replacing vulnerable algorithms or rethinking the architecture that depends on them?
