Anyone can become a coordinator 😁 So far we are experimenting with 2 levels of "trust"

1. PoW: actually have up and running the entire coordinator ecosystem, not easy, not hard. But requires knowledge and (sometines) perseverance

2. Time running: initially new coordinators are not allowed to create orders of any size, but it's limited to certain max quantity of sats which, doubles every 2 weeks since the coordinator joined (based on the block high 😁) you need to have a coordinator working for 6 months to be able to create orders of any size.
