Global Connectivity


  • Our VIPER and ADDER block producer nodes are firewalled from the outside world to prevent denial of service attacks and malicious activity.
  • We operate 4 relays with distributed connectivity to peers in the United States, Europe, Asia, and Oceania for optimal blockchain synchronization.
  • Our nodes are connected via a redundant ring topology to ensure we stay connected to the global network even if a node goes down.

Remember: Real stake pools will never charge you for staking, and do not have access to your ADA! Pools collect a fee by taxing the block rewards before distributing it to the delegators.
