A text/file upload system.
🔗
http://bitfossil.org/ is the website system to view live indexed images, it has an abuse report to unindex presumably. TODO source? Local extraction script?
🔗
Each AtomSea payload has a toplevel transaction which links to other transactions. All the linked transactions together make up the payload. The most common payload type is a text plus image, as is the case of nelson-Mandela.jpg, which can be seen at http://bitfossil.com/78f0e6de0ce007f4dd4a09085e649d7e354f70bc7da06d697b167f353f115b8e/ where 78f0e6de0ce007f4dd4a09085e649d7e354f70bc7da06d697b167f353f115b8e is the toplevel transaction ID: https://www.blockchain.com/btc/tx/78f0e6de0ce007f4dd4a09085e649d7e354f70bc7da06d697b167f353f115b8e

See Section 2. "Nelson-Mandela.jpg" for a detailed reverse engineering of the format, and Section 1. "AtomSea & EMBII data format" for a summary of it.

http://apertus.io/ is the system to upload/index locally, and therefore likely part of the backend of bitfossil: https://github.com/HugPuddle/Apertus
🔗
The system shows the messages and the images on a single page: http://bitfossil.org/4cbb32cd27b5b5edc12d3559bdffc1355ac2a210463d5cfaadc7ce9b06675b2b/index.htm It is basically a blockchain-based Twitter.

Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014) suggests that AtomSea & EMBII are the creator's aliases.

The first upload that we could find with https://github.com/cirosantilli/bitcoin-strings-with-txid#atomsea was http://bitfossil.org/c9d1363ea517cd463950f83168ce8242ef917d99cd6518995bd1af927d335828/ on block 272577 (2013-12-02). It reads:
I WONDER WHAT HISTORY WILL THINK ABOUT THESE FIRST FEW BUGS...HA HA HA. NOBODY IS PERFECT.
which is perhaps a reference to a possible previous failed upload http://bitfossil.org/4b72a223007eab8a951d43edc171befeabc7b5dca4213770c88e09ba5b936e17/ This illustrates the beauty of the blockchain very well: unlike with version control, you don't just see selected snapshots: you see actual debug logs!!!

The second one is WeAreStarStuff.jpg http://bitfossil.org/8d1b3c094b782198deb7381efb57b1208244375e7a1029ec159306d6a8fd25d8 showingAtomSea and EMBII together.

And then we meet Chiharu, EMBII's partner, with her hair painted blond :-) iLoveYouMore.jpg

🔗
Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014) actually has some images with matching names (see HTML names of the image), so we could use those as reference to reverse engineer the data.
