How the price is set
Each node's operator sets a price per GB. The marketplace shows it with the 20% network fee already included, so the number you see is the number you pay. A 2-hop route adds the entry node's price: you pay both nodes' prices plus the fee.
The price is fixed into your session when you connect. If the operator changes it later, your session keeps the old price until you reconnect. Operators can change a price at most once per 24 hours, and an increase can be at most three times the current price. olcRTC traffic is the exception: from 20 November 2026 it has one network-wide price per GB, read when the traffic moves instead of fixed when you connect.
