Gifted education Updated +Created
If school weren't bullshit, 99% of students would be in gifted education for what they truly love and are good at.
What is sad about many programs is that they are exclusivist and non scalable, selecting people some how and non scalably educating them. We need a more "here's some projects let's do them whoever can" approach to things, maybe like Google Summer of Code.

Cool data embedded in the Bitcoin blockchain Updated +Created
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).

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:
  • themes: if multiple items fall in a theme, we tend to put it there first
  • then by media type if they don't fit any specific theme
  • then by encoding
  • and finally chronologically within each section
Who said it was easy to be a museum curator!

Get Bitcoin transaction id from position in dat file Updated +Created
Suppose we specify:
  • a .dat file
  • the offset in bytes within that file
The question then is, which transaction is encoded at that position of the file?
This would allow us to index inscriptions in the .dat files directly with fast C tools, and then retrive the transaction ID to get cleaner data and metadata.
It should be possible if we managed to take the information from bitcoindev.network/understanding-the-data/ and dump into an indexed SQLite database.
I tried to start things off with LevelDBDumper:
LevelDBDumper -d ~/snap/bitcoin-core/common/.bitcoin/indexes/txindex -f btc.csv -q -o . -t csv
but that consumed all 64 GB of RAM on P51... github.com/mdawsonuk/LevelDBDumper/issues/15
But OK, nevermind that repo, it can be done easily with the LevelDB API of any language: bitcoin.stackexchange.com/questions/121888/what-is-the-data-format-layout-for-txindex-leveldb-values. Just the data seems wrong and we don't know why.
