There are apparently two methods:
- in the script, e.g. as in the Genesis block message
- in output addresses
Specific implementations:

TODO: it would be cool to have something like bitcoinstrings.com but including the actual transactions:

This is a collection of cool data found in the Bitcoin blockchain using techniques mentioned at: Section "How to extract data from the Bitcoin blockchain". Notably, Ciro Santilli developed his own set of scripts at github.com/cirosantilli/bitcoin-inscription-indexer to find some of this data. This article is based on data analyzed up to around block 831k (February 2024).
Drop some Bitcoins at 3KRk7f2JgekF6x7QBqPHdZ3pPDuMdY3eWR if you are loaded and like this article in order to support some much needed higher educational reform: Section "Sponsor Ciro Santilli's work on OurBigBook.com".
When this kind of non-financial data is embedded into a blockchain some people called an "inscription". The study or "early" inscriptions had been called a form of "archaeology"[ref][ref]. Since this is a collection of archeological artifacts, we call it a "museum"!
One really cool thing about inscriptions is that because blockchains are huge Merkle trees, it is impossible to censor any one inscription without censoring the entire blockchain. It is also really cool to see people treating the Bitcoin blockchain basically like a global social media feed!
Starting on December 2022, ordinal ruleset inscriptions took the bitcoin blockchain by storm, and dwarfed in volume all other previous inscriptions. This museum focuses mostly on non-ordinals, though certain specific ordinal topics that especially interest he curators may be covered, e.g. Ordinal ruleset inscription porn and ordinal ASCII art inscription.
Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014) is a mandatory precursor to this article and contains the most interesting examples of the time. But much happened since Ken's article which we try to cover. This analysis is also a bit more data oriented through our usage of scripting.
Artifacts can be organized in various ways:In this article we've done a mixture of:
- chronologically
- by media type, e.g. images vs text
- by themes or events, e.g. the Prayer wars or Mt. Gox' shutdown
- encoding, e.g. AtomSea & EMBII vs raw images
Who said it was easy to be a museum curator!
Less evil are BLOBs that come from Reproducible builds.
Some of the most remarkable ones seem to be:
- Alain Aspect 1982
- Hensen et al., Giustina et al., Shalm et al. (2015): "loophole-free" Bell tests
Webpack is like a magic hydra that can eat any type of file and bundle it into a single output: .js, .ts, .ccs, .scss, .jsx, .tsx,
require, import, import css from .js, it doesn't matter at all, it just digests all into the same dump.When it works, you are just left in awe and with a single Js file. When it doesn't, you're fucked and have to debug for several hours.
Demos under: webpack/. To run all of them by default:To easily make changes and reload the .js output live let this run on a terminal:
cd webpack/min
npm install
npm run build
xdg-open index.htmlnpx webpack watchExamples:
- webpack/min: minimal hello world. Doesn't do much, just copies
index.jstodist/index.js. - webpack/require:
requireandimportdemo. Both work from the same file.dist/index.jsnow contains all of:notindex.jsnotindex2.js- Lodash, a common third-party helper library specified in the package.json and installed with npm
- webpack/node: produce Node.js output, as opposed to the default web output. To test it run:Achieved simply with:
npm run build node dist/index.jsas documented at: webpack.js.org/concepts/targets/target: 'node'Fatman in Robin, - webpack/sequelize: attempts at getting Sequelize to work with webpack. It's just not supported by Sequelize:
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
