Quantum computers will break certain cryptographic protocols, but some will stay safe. Which cryptography is quantum-resistant and which isn't, and why? Watch my explanation

It will create new exciting crypto too

Quantum computers will?

Quantum money seems pretty amazing as a concept

Very well explained 👍 It gives me some ideas for creating content about PQ with our cryptography teams

Open for a discussion with @GeeqOfficial CEO @ComplicatedIsOK about it too?

Two questions arise from this: Can these structured protocols be replaced with structure-less ones? If so, I believe that will cause a hard fork for affected blockchains. Is it an endeavour they'll be willing to undergo? Nice explanation btw 🫡

Thanks! Protocols can and should change quantum vulnerable parts of their stack. It doesn't always require a hard/soft fork. For example, on Starknet, the core proving layer is based on STARKs which are quantum-resilient. This means most of the stack is already at a good place. But there are signature schemes which are quantum vulnerable and we need to replace them. But it won't require any fork. On Bitcoin it will require a soft fork at the very least, same on Ethereum.

Oh okay, this makes a lot of sense. Ethereum already has this in their straw map for the near future, I believe. Hoping they can get to do it soon, Bitcoin too.

Nice explanation. Post-quantum security deserves more attention than it gets.

Agreed. And even more than attention, it requires an action.

The math behind Shor's algorithm is the reason, and STARKs were built with exactly this in mind.

Good explanation. Future-proofing infrastructure means thinking beyond today's threats, especially for systems expected to operate for decades.

量子威胁被夸大

很棒的讲解

This is a great breakdown @EliBenSasson!

I expect technical jargon like "symmetric" & "asymmetric". But this is a far more accessible explanation.

is the fear real yet

If the security of a cryptographic primitive rests on a computational problem that is known to be efficiently solvable by a quantum computer, then it’s not quantum-resistant.

bro quantum threat still feels sci-fi but we gotta stay updated lowkey curious which chains actually prepared not watching vids tho i need bullet points

I don't think there is a quantum-safe chain yet. There are ones that started working on that, and there are a few which will have an easier path to quantum readiness (Starknet is one such chain)

Crypto talks a lot about decentralization, but long term survival still comes down to the math holding up.

How would you price the chance we see production quantum attacks on non-resistant crypto by 2030?

quantum resistance is a distraction. the real issue is coordination infra that prices actual demand not just theoretical threats.

quantum is coming eventually

hmm, so structureless primitives are the way to go? interesting
