user63492: I've been working on a tool to decode hex messages inserted into OP_RETURN.  Whilst looking at strings in the blockchain I keep coming across user names with the format id:name.id.
If you run strings over a blk*.dat file you will find strings such as:
id:muneebmajeed.id
id:andrewlawrence.id
id:nicholas_studholmewilson.id
id:jorisheijne.id
id:algoventures.id
id:bgardineer4.id
I can't figure out what they are?

user63387: As mentioned in the above comment, these are Blockstack IDs.
