how prepared is Ethereum for the emergence of quantum computing today? feels like we are practically on the verge of an “any day now” moment where one or more nation states / corporations have a significant breakthrough also, what happens to Bitcoin?…

What happens to every single encrypted thing? IMO in that world, Ethereum is quite low on the list of targets, and can also likely adopt similar mitigations to what “everyone else” does, assuming we haven’t moved to an L1 zkEVM.

I believe there are papers with anti quantum cryptographic methods that will be eventually rolled up to ethereum and others, basically there’s a way we can create a quantum cryptographic algorithm without needing to have the full quantum computer ready yet

Talking to some scientists who work with quantum computers, they argue that Blockchain might be at risk... but you can always switch to Blockchain on quantum computers to keep it difficult to decrypt. Stay ready.

We're miles away from anything useful. Needs ITRO of a few million qubits to start being useful. The most powerful compuyer is around 500 qubits atm. It's estimated that hundreds of millions are needed to break military grade encryption.

Just Bitcoin or all encryption?

I don't think it is as close as many people believe. We are still in the noisy qubit era. A large number of qubits are still needed to make a single logical qubit

I remember @justindrake coming to the conclusion/idea (in the @bankless episode on ETH as Sci-fi money) that quantum computing might just be a resource for strengthening Ethereum security.

if you had a magic key that could unlock anything, there are higher value targets than Ethereum i do agree we need more research in this direction sooner rather than later though

From the top of my head: - ECDSA used for public key derivation is broken. - Hashing algorithms are weakened by 1/2 roughly. - BLS signature aggregation used in PoS is broken. - KZG used for blobs is broken. The solution is to migrate to post-quantum algorithms like lattice-based.

ECDSA REKT (EoA's use this) Some SNARKs REKT BLS Validator keys REKT KZG REKT keep in mind I only have a high level understanding of this topic, but all these are theoretically quantum vulnerable. But its not like they will all break at once, they all have different way they work and other considerations like keysize

The only blockchain I have heard that has any protection from quantum computing already is Algorand. Prolly cause Silvio is too smart for this world 😂

no nation state can create a powerful enough quantum computer so quickly that no one has time to find out about it we talk about years-long onset of the problem, “ohhh XYZ company made X qubits computer which is pretty close to break our cryptography, we gotta start thinking how to switch to quantum safe crypto”
