Ordinals are inscriptions created with the protocol described at: docs.ordinals.com/inscriptions.html The protocol was designed by developer Casey Rodarmor, and shares a few similarities with the AtomSea & EMBII protocol.

The protocol also includes a way to have ownership over inscriptions, effectively creating an NFT system on top of the bitcoin blockchain. AtomSea & EMBII also already had such a system however. In either case, Ciro Santilli couldn't give less of a fuck about who owns some random publicly viewable digital asset.

For whatever reason, orinals became extremelly popular compared to the AtomSea & EMBII format, leading to millions os inscriptions, and 10k+ images as of block 830k. They also started to take up a substatial portion of the available block space.

This in turn led to a lot of child porn rediscussion, and people linking back to this page to view earlier inscriptions: incoming links.

Unfortunately, unlike AtomSea & EMBII and even cryptograffiti.info uploads, most ordinals are designed to be just souless bulk collectibles, as with as much artistic merit as any random collectible card set or postage stamps you may find at a newpaper stall. To make things worse many of them are likely algorithmically generated. Eternal September had truly arrived to the Bitcoin blockchain. As a result, machine learning would be almost essential in order to find interesting uploads amidst such bulk.

The i0 at the end of the URL above means "inscription 0". This is because a single transaction can have multiple inscriptions.

Some of them have sold for high prices. Magic Eden is a popular interface for trading them:

The ordinals also started taking up large portions of the Bitcoin blockchain:

Apparently the "Taproot" Bitcoin update made it easier to upload image-sized data once again, which had become prohibitively expensive 2023 and much earlier:

Mahayana adds a bunch of stuff on top of the Pali Canon. Most of it appears to be random mysticism. Maybe there is something good in it... maybe.

The idea is cool. It really unifies front-and back end.

But Ciro Santilli feels the approach proposed by FeathersJS of being a glue between bigger third-party Front-end web frameworks like React and backend (object-relational mapping) is more promising and flexible.

The lab that made Chicago Pile-1, located in the University of Chicago. Metallurgical in this context basically as in "working with the metals uranium and plutonium".

Given their experience, they also designed the important X-10 Graphite Reactor and the B Reactor which were built in other locations.

The meta of a game is the currently dominating know strategy or set of strategies, see also Section "Nash equilibrium".

OK, you have to share your phone with the company to prevent spam which forces us into messaging software that force you to have a mobile phone, but why do you also have to share your phone with contacts? So you are then forced to give your phone number away on the Internet.

The main way to sequence DNA methylation. Converts methylated cytosine to uracil, and then we can sequence those.

TODO is there any relationship between this and the Josephson effect?

Experimental observation published as Experimental Evidence for Quantized Flux in Superconducting Cylinders.

This appears to happen to any superconducting loop, because the superconducting wave function has to be continuous.

Video "Superconducting Qubit by NTT SCL (2015)" suggests that anything in between gets cancelled out by a superposition of current in both directions.

Bitcoin blockchain image indexer and uploader. Uses fake P2PKH address.

At some point it stopped using Bitcoin mainline and moved to Bitcoin Cash instead: www.newsbtc.com/news/bitcoin/cryptograffiti-rejects-bitcoin-core-bch-now-available-payment-method/ and therefore became useless. Existing indexes seem to have been broken as well.

Also, based on the timing of Figure "Erich Erstu", this service may be responsible for a large part of the raw JPEG images present in the blockchain from block 416527 (2016) onwards. This is also suggested by the comments at Figure "Tank Man".

A Quantitative Analysis of the Impact of Arbitrary Blockchain Content on Bitcoin gives the interesting insight that all its transactions seem to return change/fees to one or two given addresses, thus making it very easy to list all their uploads if they were consistent! So all we need are some starting points, which we have mostly due to ASCII mentions of the site on known inscriptions, all of which have a few common spent addresses at the very end:so we just have to solve get all Bitcoin transactions from and to a given address and we are done.
