Self-custody only works as long as the cryptography does. @JoeMattia on sovereignty, self-custody, and getting back to our roots.

Proton has been post-quantum since 2023.

People have no idea how close Quantum computers really are Some VCs are aware of it And some are still blindsided

Eli is directionally correct that lattice-crypto has more algebraic structure than hash-crypto and that this structure could theoretically be used to break it, altho i think the newness of lattices is a bit overstated. Lattice crypto originally started as offensive cryptanalysis, not a defensive structure. In cryptography, you generally want all-or-nothing systems. If I try to guess your password and I’m even one character off, I should get no clue about how close I was or which characters were correct. In practice, this is difficult. For example, if I respond slightly slower depending on how many characters are correct, then you can use timing to gradually extract the complete password. This is where timing attacks come from. Lattices are like vector fields but instead of taking any linear combination of the basis vectors (with real coefficients) you only accept integer coefficients. So you have some building blocks and you can combine them but not shrink or stretch them. It’s similar to how crystals have evenly spaced atoms in multiple dimensions. The basic idea in lattice attacks is that you find a bunch of clues or partial solutions and make each one a basis vector. Then you try to find (“Learn”) a combination of them whose sum is small (Short Integer Solution, SIS), which simultaneously combines the partial solutions to make a complete solution. This method can be used to attack elliptic curve signatures when the nonces used are biased, not uniformly distributed. Lattice signatures and zk-proofs use similar ideas but defensively, to find problems that resist lattice attacks. Learning-With-Errors (LWE) essentially takes that short integer solution and adds noise to it so that an attacker cannot use straightforward linear algebra to solve it. Then you can prove you know the solution without revealing it by solving a related problem. Hash-crypto works quite differently. It basically uses one-way functions (hashes) as a building block and you prove you know a secret by selectively revealing the inputs to a publicly-committed output. Since hash-crypto doesn’t have any algebraic equations in its structure, people say it has less attack surface, which is true. The tradeoff is that you have much larger signatures and it doesn’t have nice threshold schemes or key exchange algorithms or encryption, which all rely on that missing algebraic structure. Both hash-crypto and lattice-crypto rely on the security of hash functions, tho, so the reduction in attack surface is a clear win for hash-crypto. It would be great if we just had full security-proofs for some crypto-system so we wouldn’t have to rely on heuristics like this, but that’s just where we are in our scientific knowledge as a species. Maybe AI will help us solve P =? NP and that will lead to provably secure systems.

Joe Mattia says Quantus was built quantum-safe from day one, backed by about $2.5M from angels only and no VCs, so the rest of crypto has a benchmark to measure against. @QuantusNetwork @JoeMattia

Proud to be part of the Quantum Alliance. @YuviLightman is one of its founding contributors, helping build standards that make post-quantum readiness verifiable.

GN CT 🌙 BTC is holding near $81.5k. Liquidations cooled to about $315M, a third of the midweek flush. Google search interest is at a multi-year low. Leave the wick. 🌙 The page is the Quantum Alliance. Nine firms, including Hacken, Midnight Foundation, Quantus and Postquant Labs, formed it to write shared quantum-resistant standards and migration notes for networks like Bitcoin and Ethereum. A working group is not a patch. It is a calendar for who moves first. Sit with the public keys that stay exposed, not the announcement. The fork is Monday. The quantum note is longer. Sleep on the one that does not expire this week. DYOR. NFA. Rest. The chain keeps running. 💤 #GN #Crypto #Web3 #Bitcoin #Quantum

We spend endless hours debating TPS, gas fees, and onboarding the next billion users, but almost nobody talks about what happens when our underlying cryptography becomes completely obsolete. I have been following post-quantum research for a while, and the biggest bottleneck has always been ecosystem fragmentation. Having one chain attempt an isolated cryptographic migration while wallets and bridges remain on legacy standards achieves nothing. The launch of the Quantum Alliance by @quipnetwork alongside Keystone, The Vault, Hacken, Abelian, Midnight Foundation, Quantus Network, INTMAX, and American Fortress solves this exact coordination problem. It unites hardware wallet providers, security auditors, and layer protocols under one unified framework. True resilience is not an individual feature. It is a shared baseline across every layer of the network.
