Cool data embedded in the Bitcoin blockchain / Cursed ordinal by Ciro Santilli 35 Updated +Created
These were ordinals that were only indexed in later versions of the script. So to prevent changing the useless indices of existing ordinals, they gave them negative numbers.
The word "cursed" is a meme from the 2010/20s, e.g. knowyourmeme.com/memes/cursed-images--2.
Some examples:
This section is about ordinals that are interesting primarily due to technical reasons linked to edge cases of the protocol.

This section is about groups of ordinal ruleset inscription that share a theme and were presumably created by a single entity.
These were found by running object detection software for some porn/nudity detection. We need to run some more, all sex was likely missed: github.com/GantMan/nsfw_model/issues/160
Daisy chain Bitcoin inscription by Ciro Santilli 35 Updated +Created
This is a term invented by Ciro Santilli, and refers to a loose set of uncommon Bitcoin inscription methods that involve inscribing one or a small number of payloads per Bitcoin transaction.
These methods are both inefficient and hard to detect and decode, partly because Bitcoin Core does not index spending transactions: bitcoin.stackexchange.com/questions/61794/bitcoin-rpc-how-to-find-the-transaction-that-spends-a-txo. This makes finding them all that more rewarding however.
On the other hand, they do have the advantage of not depending on any block size limits, as their individual transactions are very small.
Inscribing anything large would however take a very long time, as you'd have to wait until the previous payload chunk is confirmed before going to the next one. This alone makes the format impractical perhaps.

. Poor Charles was too debilitated by Alzheimer's disease to give the talk himself! But if you've got a pulse, you can get the prize, so all good.

Crystal radio by Ciro Santilli 35 Updated +Created
This was the first generation of commercially successful radios.
It uses a crystal detector as its diode, which is a crucial element of the radio, thus its name.
They were superseded by transistor radios, which were much more reliable, portable and could amplify the signal received.

Crystal detector by Ciro Santilli 35 Updated +Created
The first diodes. These were apparently incredibly unreliable, especially for portable radios, as you had to randomly search for the best contact point you could find in a random polycrystalline material!!
And also quality was highly dependant on where the material was sourced from as that affected the impurities present in the material. Later this was understood to be an issue of doping.
It was so unreliable that vacuum tube diodes overtook them in many applications, even though crystal detectors are actually semiconductor diodes, which eventually won over!
For a long time, before artificial semiconductors kicked in, people just didn't know the underlying physical working principle of these detectors. What I cannot create, I do not understand basically.

This one took a while! Major developments were from the 70s! Perhaps it took the Internet revolution to make its importance clear.

  • Prelims: first year undergrad
  • Honour school; other years of undergrad, sometimes it includes masters others not which is confusing
  • MPhil, MSc, MSt: masters
