The MitID design is strange, but in this regard it is well done.

For those companies that have offices in both countries, and for which the synchronicity matters, it is not that difficult to just have special office hours.

It is sad that FreeCAD gets all the attention. If Solvespace had some of it, and the development time following from it, it could get improvements and some of the cool stuff in their pipeline. That would IMO make it a much better CAD program than FreeCAD could ever become.

But you are also right that this is not the only way they work. With the XZ Utils backdoor (2024), we normal nerds got an interesting glimpse into how they create a zero-day. It was luckily discovered by an american developer not looking for zero-days, just debugging a performance problem.

But even if the authority was a private company, I think it would be an improvement compared to the current situation. In this situation your personal information would be held by this one company, and not whatever provider that needs to verify your age. Also, you would be able to use the commitments, that this private authority gave you, without any coordination afterwards. The authority would not know about your transactions.

The communication in connection with a transaction would only go between the identity owner (Bob) and the provider (Cycle shop).

It requires that Bob proves posession of a private key, that only he has ever had. That private key could be generated specifically for the commitment that he got from Alice.

But nothing prevents it from being a private company, although I cannot see a sound business model for it. Also it would need to project great credibility for customers to trust them with their information.

That would at least be a good and also simple solution. Maybe there is a perfect solution, but then I dont know it.

It is crazy that the solutions Discord goes for are IDs and selfies. It definitely gives the impression that there are shady ulterior motives.

Hash chains are simple. If they were adopted, Discord would clearly be in bad faith taking the steps that they do now. If you search you will find quite a bit of information. My introduction to hash chains is for for age verification specifically: https://spredehagl.com/2025-07-14/

This state of affairs is partly due a change in the nature of products. They are in general more complex and no longer meant to be repairable. They are meant to have shorter life spans, and if serviceable are meant to be serviced by professionals. How much that is an improvement for the consumer, is questionable IMO.

I think that reading the classics can be beneficial to the first type. But some of the classics can be very bleak. Its not fair to the children to make them read those. 1984 is probably in this category. Read Animal Farm instead. It is also better for the second type of children.

If done properly, and in moderation, I think reading classics is beneficial.
