Golem is a decentralized supercomputer that is accessible by anyone. The system is made up of the combined power of user’s machines from personal PCs to entire datacenters. Golem is able to compute almost any tasks from CGI rendering through machine learning to scientific learning. It utilizes an ethereum-based transaction system to clear payments between providers, requestors and software developers however it is safe because all computations take place in sandbox environments and are fully isolated from the hosts’ systems.
