@elraulito no proper entropy (no proper random seed) and no secure element (someone stealing the gameboy can access the private key).

So not a solution.

Cool project though anyway.

CIP-23 (minPoolMargin) will be implemented in full for the upcoming Dijkstra Hard Fork!

Huge appreciation to @ATADA_Stakepool and the SPOs who pushed for this, and to the members of the @IOGroup ledger team who are doing the implementation work for FREE

🔥🔥🔥

[ATADA / ATAD2 Cardano StakePool Austria @ATADA_Stakepool]

SPOs - we did it! minMargin CIP23 will be fully included in the upcoming Dijkstra Hardfork to PV12 and not in PV13 many months away!

Was not easy, but the CoreDevTeam showed that they are listening and are willing to make things possible. ❤️

So a big thank you to the DevTeam, lets keep working together. 🫱🏻‍🫲🏽

i rebuilt satoshi's 2009 bitcoin.exe byte for byte!

afaik nobody has been able to perfectly recreate the executable published in 2009 from source, because we didn't know the exact build environment that was used.

using opus 5.5, i reverse-engineered satoshi's build machine from the binary.

it now outputs an exe with the exact same sha256 as the 2009 release!

🚨🇫🇷👮‍♂️ ALERTE INFO !

DES POLICIERS EN CIVIL FILMÉS EN TRAIN DE METTRE LE FEU À UNE POUBELLE ?

Lors de la mobilisation du 17 octobre, des individus soupçonnés d’être des policiers en civil ont été filmés en train de tenter d’incendier une poubelle en se mêlant aux manifestants.

Une jeune femme aurait d’abord éteint le feu, avant que l’un des individus ne revienne pour le rallumer.

Plusieurs élus demandent des EXPLICATIONS au ministre de l’Intérieur,@NunezLaurent, afin de faire toute la lumière sur ces images.

@Ledger @DonjonLedger U guys should really consider putting some type of tamper-evident seals on ur @ledger wallets manufactured in Vietnam because hackers in Vietnam are opening ur wallets & installing extra hardware inside the devices to steal people's coins, I told @DonjonLedger about this already.

Each coordinate of a closed outline has its own real Fourier series: x(t) = ∑ (aₖ cos kt + bₖ sin kt), and the same for y.

A cosine and sine of frequency k make one arm of length √(aₖ² + bₖ²) turning k times per lap. One chain sets x, one sets y, and the pen sits where their guides cross. With N harmonics per axis the knight is off by 30.2 % of its height at N = 1, 0.70 % at N = 50.

At N = 1 both coordinates are pure sinusoids: an ellipse.

The parameter committee has spent months/years debating on how to accurately gauge SPO sentiment about raising stakePoolTargetNum from 500->1000.

As part of this, myself and another member of the parameter committee meticulously drafted all the arguments for and arguments against and linked them in separate documents so that voters could have a balanced view of both arguments. We linked these inside of a neutral-language Info Action body for SPOs to consider.

Because Info Actions have no ratification threshold and stakePoolTargetNum isn't a parameter that SPOs vote on through governance, the parameter committee collectively agreed to use a specific threshold of explicit YES > explicit NO for this Info Action. This is already above and beyond what the protocol and the Constitution require and we went out of our way to give SPOs a voice on this.

Unfortunately, a community member who is opposed to the parameter change hijacked our draft and the years of effort that went into it, changed the threshold to suit his desired outcome, and submitted it without consulting anybody.

Even if the we can reasonably disagree about what the threshold should be for this vote (remember it is not required at all), taking other people's work, twisting it, and submitting in a manner to suit your own narrative is extremely disappointing to see.

I'm very disheartened by this after having spent years of my own, uncompensated effort building to this point only to see a community member undermine it like this.

If you want to see the real draft that the parameter committee put together, you can read it here. Also the case for and case against are linked as well, so you can see both sides of the discussion fairly.

I can't speak on behalf of the others, but I will be interpreting the outcome of the vote based on the criteria that the parameter committee collectively agreed on, regardless of what this Info Action says.

[Adam Rusch @AdamRusch]

In my “Blockchain & Society” class, I love using real examples to help students understand how decentralized ledgers works. This semester, I was able to take things up a notch by using Claude Code to build a custom Cardano Blockchain Explorer as part of our class activity.

My course is generally taken by students who have little to no experience with blockchains or crypto. Many are preparing for careers in technology and information consulting, where they will analyze different systems, assess their organizational value and limitations, and communicate recommendations to clients and decision-makers.

In past years, I have done an exercise where I put a blockchain explorer up on the screen and walk students through how transactions move through the chain. But this time, I wanted them to learn about blockchain transactions by sending real assets over the Cardano network themselves.

For that I had planned out a worksheet and a workflow where each student would receive some ADA, send transactions to each other, and then send some to a common address that I could use as a tracking point for the whole class.

My intention was to use the Claimpaign platform to distribute the ADA, but I didn’t get it set up in time for students to use it in class. As I was getting ready to teach, I realized I would need a different way to get ADA into their wallets. Luckily, I knew that the VESPR wallet lets me use Face ID on my iPhone in place of the signing password, which means I can send a transaction about as fast as I can look at my phone.

So when class began, I explained the activity, passed out the worksheet, and had students install either VESPR or Eternl on their phone or computer. Then I went down each row and manually sent every student 4 ADA to seed their wallet. Thanks to the Face ID option, this did not take me very long to accomplish. As students got set up with their ADA, they started working with a partner on the worksheet, and once everybody had traded with each other, they sent their ADA on to the classroom wallet.

I had originally intended to look at all of this in an ordinary Cardano blockchain explorer, but I was having fun designing the activity, so I asked Claude to build me a custom explorer that would show the transactions and let me reveal the transaction flows my students had engaged in, step by step. (Hat tip to @SmaugPool for the UX inspiration from @pool_pm.)

The whole class worked out fantastically. After students had traded with each other and sent ADA to the classroom wallet, I used the custom explorer to collect the on-chain data via Koios and display it in a way that showed the transactions lined up one next to another. We had a discussion on how the transactions worked and how their structure showed the inputs and outputs we had been discussing in class, not just for Cardano but for Bitcoin as well.

We also talked about how their wallet software was their way of controlling their private keys for the blockchain network, just like the activity from the first week of class where I had them set up PGP key pairs so they could send secure email and get a feel for key-pair cryptography. We discussed the security implications of a mobile software wallet like VESPR compared with cold-storage methods, as well as situations where convenience might be prioritized over stronger safeguards.

Overall, I am extremely happy with how the activity went, and I am thoroughly impressed with the way Claude was able to extend my ability to teach this lesson. While I didn’t strictly need a custom blockchain explorer to show my students the activity they had engaged in on chain, it let me show what was happening exactly the way I wanted so that I could reinforce the lessons I had been teaching in class.

There is a lot of discussion right now about how AI tools are being used by instructors and students. While there are certainly real downsides to becoming over-reliant on AI to build new products and do analysis, there are also ways it makes things better. It is undeniable that most of my students will be graduating into jobs where they will be using AI systems every day. I am actively working to shift my teaching to help them learn how to manage their interactions with these systems. Rather than requiring as many written assignments that could simply be produced by AI, I am doing a lot more hands-on in-class activities like this and asking students to give oral presentations. I have found that the preparation required to explain a concept to your peers is what makes you understand it fully.

I have put the activity in a GitHub repository so that anyone who teaches a blockchain course can use these materials and modify them for their own needs. I hope you find it useful!

Good Morning

Cardano (with Masumi) has now been merged as a working implementation into the official x402 repository.

Previously only the specification was in there but now Cardano is also available via the official x402 packages in various programming languages.
