DefCon26 - Crypto & Privacy Village badge

This is a breakdown of the Crypto & Privacy Village Badge from DC26 (2018).

There are references on Twitter, the Crypto & Privacy Village Website, and the badge itself regarding the website "https://goldbug.cryptovillage.org/"

There is also a BBS looking portion of the Goldbug CTF:

And here is their Twitter handle: @CryptoVillage

The front of the badge is super cool looking; reminds me of an atom or nucleus:

The light pattern changes during startup and eventually settles on this pattern (no modifications or code changes to the badge):

I did see other badge holders at DefCon26 that had changed the LED light pattern on the front to show all green, and another person had the badge LED slowly changing colors.  I didn't get any pictures of their badges since I was told getting pictures of other attendees is a BIG  no-no.

There Is a small 150mAH battery that is stuck to the back of the badge with double sided sticky tape.  Since there is a trend this year of hiding clues under the battery or under tape, I decided to remove the battery:

And to remove the double sided tape.  Unfortunately there wasn't any info underneath the tape, just circuit board traces:
