Cool data embedded in the Bitcoin blockchain / AtomSea & EMBII (2013-)

"AtomSea & EMBII" refers to an upload system for various media types includeing text, images, HTML pages and audio.

The official name used by its creators for the protocol is P2FK (Pay To Future Key).

The name "AtomSea & EMBII" is a reference to the online handles of its creators. That string appears to be added as padding in the protocol and is therefore visible repeatebly in the blockchain, though it is sometimes cut up a bit. The following online profiles of the creators feel authentic:

- twitter.com/EMBII4U EMBII replies on Twitter and given his knowledge of the subject he's undoubtedly one of the creators, not to mention likely owning private keys and repeatedlyt proving so

Tried saying hi to them at: twitter.com/cirosantilli/status/1382080760774033415 and they replied: twitter.com/AllenVandever/status/1563964396656812034

The feature-set of their protocol is impressive:

various media formats:
- multipage setups: The Mahabharata bitfossil.com/0618f12af65a4e82f8e7b41f8578721dfeb109e9a73ff71aebdbc982696e3720/

- selling your uploads! I.e., they've likely created the earliest Bitcoin-based NFT system. For example, this lists the buy and sell orders for Figure 38. "YellowRobot.jpg": p2fk.io/GetObjectByAddress/17mdB8cVCQVhBi46bF43JpniZ4DAgE3JjH?mainnet=true&verbose=true
- sending messages to other people. TODO example.
- voting. TODO example.
tooling:
- Sup!? a local GUI client

- bitfossil.org is an indexer website for the inscriptions. For example bitfossil.org/67b2facfd8160d4fa11b02829b6387d07537b57a7a24f19b029b2a5ae7b81830/ displays Figure 38. "YellowRobot.jpg" which was inscribed at toplevel transaction tx 67b2facfd8160d4fa11b02829b6387d07537b57a7a24f19b029b2a5ae7b81830. Functionality seems a bit limited compared to the local clients however, e.g. you can't see all uploades by a given author.
- apertus.io/ TODO vs Sup? At x.com/EMBII4U/status/1929498259883536886 EMBII tries to explain it but not sure.

Basically they've created a fully descentralized Bitcoin-based social media. Their system is basically a sligly more clunky superset of Ordinal ruleset inscriptions, just way older and way less known for whatever reason.

Each P2FK inscription is done over P2FKH payloads. Each inscription 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 bitfossil.com/78f0e6de0ce007f4dd4a09085e649d7e354f70bc7da06d697b167f353f115b8e/ where 78f0e6de0ce007f4dd4a09085e649d7e354f70bc7da06d697b167f353f115b8e is the toplevel transaction ID: www.blockchain.com/btc/tx/78f0e6de0ce007f4dd4a09085e649d7e354f70bc7da06d697b167f353f115b8e See Section 1.2. "Nelson-Mandela.jpg" for a detailed reverse engineering of the format, and Section 3. "AtomSea & EMBII data format" for a summary of it.

The system shows the messages and the images on a single page: bitfossil.org/4cbb32cd27b5b5edc12d3559bdffc1355ac2a210463d5cfaadc7ce9b06675b2b/index.htm It is basically a blockchain-based Twitter.

At twitter.com/EMBII4U/status/1762501350997233976 (2024) EMBII mentions that he was inspired by the Satoshi uploader.
