Organization.
This site is a mess. Work on chunking.
You do have main things you would like to work on like:
The Blinky Project
https://www.youtube.com/playlist?list=PLbVZNfQhcZ3eQpiBUY_0IaXPmPE5pZoOT
(finish the packaging of the message to stream it live with the cryptochip)
ultimately you are using the P256 curve with this, and having it appear in a DID document. You have Ed25519 as well, and you think it might work natively better in some cases if not for just the extra security comfort.
Satellite Link
You have a couple of links. Do you focus on LoRa, or do you focus on more frequencies? There are more links in this blog.
Like this, but for a satellite ground station instead of a 3D Printer

Data Management
You have been looking heavily at CQL and FQL. You like the predecessor FQL because it appeared to allow for JSON import. You believe that this will help with JWT, JSON-LD, and LD-Signatures and how they can play together some way.(edit 1) To learn how to go forward breaking stuff is necessary in addition to reading. You have a lot of stuff to read, and it is good that you are a great archivist, but by failing you make progress. Do the exercises. Try category theory again and again. Review the basic premises of what makes a category. Make sure you are comfortable with groups, monoids, ring, subgroups, semigroups, magmas....there is a way that they relate. https://en.wikipedia.org/wiki/Category_(mathematics)
This starts getting into gremlin, which you will not only need to understand as a user [(https://www.youtube.com/watch?v=RkMYZcQEXOk) great start ] but also theoretically. https://www.slideshare.net/slidarko/problemsolving-using-graph-traversals-searching-scoring-ranking-and-recommendation , https://arxiv.org/abs/1011.0390 . It is good that you are reading about the theory of computation in the discrete mathematics textbook. This is a good playlist to look at because you are getting lost reading https://www.youtube.com/playlist?list=PLBlnK6fEyqRgp46KUv4ZY69yXmpwKOIev&app=desktop . I do not know if reading the chapter before delving into the exercises is a good idea. I know you have tendency to read a lot of material before jumping in.
CQL is for ETL, mmADT is for data processing: custom programming languages/parsers for existing programming languages; various processing methods (distributed near time processing looks interesting); and various storage mechanisms: key-value stores... etcetera. These two will be merging in some way. Cayley graphs are interesting. (study william fisets data structures and graph algorithms...map back to discrete mathematics book, group theory book, abstract algebra book...etc...stay small) ... if you play with CQL or FQL for a few days, this is not sufficient, it might help.

To Do:
I'm seriously planning on uncommenting the JSON parser in FQL so it appears as a menu option, and hope that it doesn't splode. It is my to do.

Free write / musings of why have a distributed economy
Why do you want to build a distributed economy?
-- Less bureaucracy
Why do you want less bureaucracy?
-- People get in the way.
Will less people get in the way if you build a distributed economy?
-- I will be easier to find people (search). People will disagree, but at least they will be able to find what they want in light of what they know.
You want order in computer systems so you can have disorder in the real world.
=====================
Why do you want to build a distributed economy?
I want to work with self-organized groups that are optimized based on interest.
Why?
I had trouble during childhood finding like minded individuals to work with and this continued during my schooling and career.
Why?
I know the people who want to work with me are out there, but it is not easy to find them.
Why?
People choose careers based on fields, and often these fields do not match them perfectly. It is like choosing between small-medium-large instead of a custom fit to skills and interests.
Why?
Why are you using linked data?
It allows individuals to express interrelations within their domain of interest and compare this with others in an interoperable way
Edit (5:36 AM .. sept 21st): This distributed economy project is for engineering type projects. I believe that I was originally motivated to start it due to childhood, college, and graduate school wounds inflicted by family.
Edi (9:13 AM ... sept 21st): People come and go as autonomous agents, and can be part of one or more virtual organizations. These organizations are like flash mobs. They come together for a project, and then disband when it is finished. Information is made interoperable so parts and projects can fit together like lego blocks. Value networks are used to model the contributions, so people can be compensated for their work.
Earlier writing:
"
We need a system that encourages learning and creates business and
research opportunities through self-organization. The traditional model
is failing us. We must go beyond the traditional model and personalize
education, business, and research with self-organization, so that
individuals can contribute their own ideas and work together toward
common goals.
"
Why CQL?
can I have interoperability enabled by algebra???
The earth was the center; then the sun; then no need for center.
-- Having a world-center provides an origin; good for coordinating.
-- But there isn't just one best coordinate system.
-- Each coordinate system is a perspective.
(Read above in terms of algebra and in terms of information)
Why IoT?
Why SSI? Why do you need educational credentials? Shouldn't your work prove you did something? It is not always possible. What? To be productive?
Sometimes someone may need to learn the ropes. Like how to drive a car or a forklift.

Looking at assembly links and binary string to int conversion
from gdb:
"Examine memory: x/FMT ADDRESS.
ADDRESS is an expression for the memory address to examine.
FMT is a repeat count followed by a format letter and a size letter.
Format letters are o(octal), x(hex), d(decimal), u(unsigned decimal),
t(binary), f(float), a(address), i(instruction), c(char), s(string)
and z(hex, zero padded on the left).
Size letters are b(byte), h(halfword), w(word), g(giant, 8 bytes).
The specified number of objects of the specified size are printed
according to the format. If a negative number is specified, memory is
examined backward from the address.
Defaults for format and size letters are those previously used.
Default count is 1. Default address is following last thing printed
with this command or "print"."
I thought you might want to take a dip in assembly:
