Darknodes is a decentralized computer network. They offer their computing power and storage space to anyone who meets certain conditions in exchange for compensation. Anyone can run a Darknode, but each node must run the RenVM software via a virtual private server and deposit 100,000 REN tokens into the Darknode Registry Contract. This mechanism incentivizes the node operators to refrain from malicious behavior under the threat of losing their deposit. Darknodes collectively act as an uncertain, decentralized custodian of the digital means that users lock up on the RenVM platform. They allow users to collect fees every time the RenVM converts a digital asset into an ERC-20 token.
