What is Golem?
The Golem project is a peer-to-peer and decentralized marketplace where users can buy and sell computing power. The project wishes to be an alternative to big, centralized cloud services such as Google and Amazon. The Golem network pools global computer power and allows users to access these computing resources using the Golem token GNT.
Token holders pay people who are renting their computing power for their services, which can be used for stuff such as CGI rendering, machine learning and scientific computing. Transactions between participants are safe because computations take place in sandbox environments that are sequestered from hosts' systems.
The use of users spare computing power allows for a cheap and low-cost alternative to power-hungry super computers.
