#187 Alex Leverington & Julian Zawistowski: Golem – The Worldwide Decentralized Supercomputer

With most of the world’s computing power concentrated in Internet companies’ data centers, the Internet has become a very centralized place. The Golem project aims to build the sharing economy of computing power. This “”global, open sourced, decentralized supercomputer”” will function thanks to the combined power of a massive network of machines, from personal laptops to whole data centers.

We’re joined by Julian Zawistowski and Alex Leverington, CEO and P2P engineer at Golem. We discuss how Golem hopes to create a more balanced distribution of computing power for the Internet.

Topics discussed in this episode:

  • What is Golem and the problem it is addressing
  • What may people and companies use Golem for
  • How Golem compares to other projects like iExec or TrueBit
  • Who are the different participants in the Golem network
  • How Golem executes computations
  • The role Ethereum has to play in Golem
  • How payments work in Golem
  • The economic model for Golem’s decentralized marketplace
  • The project’s current status and roadmap
