Coin Sciences

As of March 2014, I am the founder / CEO of Coin Sciences, a company developing a set of protocols and services on top of the bitcoin network (not the currency) for issuing and transacting digital tokens over the Internet:

  • Bitcoin Colors. White paper about using the bitcoin network to transact in digital assets.
  • Coin Secrets. Displays metadata recently embedded in the bitcoin blockchain.

A bunch of stuff I conceived and developed (sometimes with others) since 2003:

  • Cloudlook. Measures the performance of cloud servers and public cloud providers.
