Proof of Relay¶
Messages sent through the HOPR network take a certain number of “hops” before reaching their destination. These hops via nodes like yours are what obscures the data and metadata from outside observers. Each hop costs a small fee. These fees are charged in HOPR, and paid by the previous node in the chain to the next node. However, this fee cannot be claimed until the data has been successfully passed to the next node in the chain. This is called proof-of-relay, and it’s how HOPR ensures data reaches its destination without revealing information about the sender, recipient, or the route the data takes.
