  Mediachain (Mediachain Labs) was a decentralized media-attribution protocol,
  seed-funded by Andreessen Horowitz and Union Square Ventures in 2016 and
  acqui-hired by Spotify in April 2017. The company is defunct and its primary
  domain (mediachain.io) is now a parked page, but its first-party open-source
  client libraries remain published on npm and PyPI and the GitHub org is public.
