Cryptocurrency project Castle has somewhat silently released their masternodes. Users can now host masternodes and receive rewards. Although the team hasn’t come out to explicitly state that their masternodes are live, they are already up and running. As at the time of writing, the network already had 33 active masternodes.

The required collateral for hosting a Castle masternode is 40,000 CSTL tokens. This is equivalent to about $2960. Details of how to set up a masternode can be found on GitHub.

Castle is a decentralized platform for the automation of airdrops. Cryptocurrency projects and developers can through the Castle platform determine how they want users to receive airdrops. According to their website:

We have created a platform where users and developers can coexist and benefit from each other through social media interaction and airdrops in a seamless way.
