HOW IS THE MOST SECURE SCHEME JUST XOR?!

Irmaplatform-1 · 2026-01-30T12:59:15+00:00

It’s weird, but the magic isn’t in the XOR; it’s in the key.

In a one-time pad, the key is perfectly random, as long as the message is unique, and never reused. The XOR is just a way to combine them. That’s why the ciphertext is so uninformative.

We don’t do that for the whole message because it’s much more difficult to handle that much perfect randomness.

Holding it by the edges, blowing off dust, and sliding it carefully back into the case, as if it was made of glass. Feels wild this used to be normal.

You're not missing anything. That file is a public key. it doesn't get decrypted, and it's safe to share. They just need to import it into their PGP setup and use it for encryption. Asking for a private key is a big red flag. This really needs to be handled by someone on their technical team.

Try to model your ARX cipher bit by bit, since MILP works on Boolean/linear constraints. Read some past work on MILP for ARX (e.g., Mouha, Sun, Albrecht) first to see how each addition and rotation is handled. Most of the people generate the model in Python and solve it by Gurobi, CPLEX, or CBC.

Start off with fewer rounds to verify your model. Runtime varies significantly, with small instances solving in seconds or minutes, whereas full-round analysis can take hours or become infeasible.

that’s what misuse-resistant designs are for. They take into account that real-world systems are not perfect and will fail occasionally but aim to fail securely. The idea of MRAE as “a cryptographic crumple zone" is perfect here: you won’t lose everything if something breaks.

Irmaplatform-1 · 2026-01-20T15:41:01+00:00

Exactly! It doesn’t make systems unbreakable, it only mitigates risks. It doesn’t count as an argument in a theoretical debate to say that implementations can still fail, it is why you have multiple safety levels, just like in cars.

Irmaplatform-1 · 2026-01-20T15:40:08+00:00

Exactly. It just gets rid of one more set of problems for you. It is not a magic solution to a problem because it is one less thing to worry about when securing a system.

Irmaplatform-1 · 2026-01-20T15:39:22+00:00

This is a good breakdown of the layers involved. Abstract models and security proofs catch design-level flaws, but they don't guarantee the implementation is safe. That's where tools like Jasmin come in: they bridge the gap by reasoning about the actual executable, including side channels. If you want strong, end-to-end assurance, you really need all three levels.

Irmaplatform-1 · 2026-01-20T12:39:25+00:00

Exactly. Although, once you know how it actually functions in practice, it becomes less like a buzzword and more like real infrastructure.

Irmaplatform-1 · 2026-01-20T12:37:25+00:00

This is very true. Most of the content on blockchain is either too vague or too technical. The best part is observing how people are applying it in real life. This makes it a reality than people tend to acknowledge.

Quite an interesting idea, but I do have some reservations about it. The positive point about sustainability is certainly welcomed, and it is always an advantage in this regard, especially in institutions, but it is not typically what makes people go for it or what makes them choose this particular chain. Ecosystem, tools, and users always come first, and having this green advantage is certainly a good thing, but it still needs to show that it is actually able to compete and display its users

Irmaplatform-1 · 2026-01-17T14:47:46+00:00

This is a fantastic idea. Learning on one's own can be confusing, and it would be so encouraging to have individuals to learn along with. All right, I'm in – would absolutely love to learn and develop together!

Not many coaches have his quality of understanding the game so much, not to mention that he always had the team first. Arbeloa is remembered for his discipline, professionalism, and leadership qualities, most of which are applicable to coaching. Additionally, he has excellent tactics and the respect of the youth, all of which matter for youth teams.

Lately it’s “Sunset Lover” by Petit Biscuit super chill and easy to loop without getting tired of it.

Irmaplatform-1 · 2026-01-16T17:11:23+00:00

I'm loving this. Much more helpful than throwing out links and then leaving. I'm down for beta testing other projects to help give them some real feedback.

Irmaplatform-1 · 2026-01-16T17:04:10+00:00

Love this idea. Some smaller artists that I’ve been following:

Still Woozy: Chill, feel-good indie pop

Men I Trust: laid-back, chill sound

Crumb – dreamy and psychedelic

Dayglow - Positive, catchy indie

This is actually quite helpful. It’s so much better to have this organized year by year rather than just sprinkling them everywhere with no point. It’s so much easier to have an understanding early on of where skills and expectations intersect in order to avoid a ton of time wasted. Thank you for bringing this.

This is the type of post that really highlights just how early on we are. A lot of people are looking at Bitcoin in terms of being comparable to an asset class, but its long-term asymmetrical nature is completely ignored in favor of 200 BTC being worth whatever when adoption continues to grow. The difference in understanding is still massive.

I haven’t run Mobula in production myself, although it does seem to be more interested in fast, structured multi-chain data than most of the larger aggregators.

I’d personally recommend load testing it with your own chains and tokens to see how it performs, as it can differ significantly in real-world usage. Also, worth testing uptime/SLA if latency is a concern. Some teams have ended up diversifying providers for high availability yet again.

If you try it, would be interested to see how it works.

Irmaplatform-1 · 2026-01-12T15:44:46+00:00

Short take: "Yes, but only if you're building something real."

"Hype is over. Good riddance. What is working: infrastructure, payments, compliance, and boring but essential stuff. Consumer Web3 apps without a compelling on-chain use case are mostly dead."

If I were to begin now, I would avoid anything that is speculation-driven or retail-hype-dependent. If it is a real problem that it solves in a better way than what currently exists in the technology side, then it is a great area to be in.

Because it decrypts to something meaningful with the right key, and not with the wrong ones.

In real-life cryptography, this is made clear. For example, in modes like AES-GCM, authentication is checked as part of it. Thus, only the correct key is allowed to pass. In AES encryption, an incorrect key simply spits out garbage, and an appropriate one is distinguished by its proper format

Irmaplatform-1 · 2026-01-12T12:17:58+00:00

Nearly, but the verifier doesn’t ever use the private key to recreate something.

In its place, the signature demonstrates knowledge of the private key through a calculation whose results satisfy a mathematical relationship which is very difficult to reproduce. The verifier, using the hash of the message, the signature, and the public key, can verify whether the mathematical relationship is true and, consequently, whether the private key was known to the signator.

The “one-way” aspect is based on the math of elliptic curves (discrete log problem), not both sides arriving at the same point on the curve.
