Responsible for moving, validating and securing the Stakenet network.
Anybody can be a Staker by running a Staking node or using a Merchantnode for Trustless Proof of Stake. Regardless of how many coins he owns.
Merchantnodes are a kind of Staking nodes.
Responsible for providing high-end network services, such as powering the XSN Exchange.
They create a massive network of computers with an incredible computational power for Stakenet. The possibilities are endless.
To run a Masternode you need 15 000 XSN.
