Who is marshal and how to become a marshal ?
A marshal is anyone willing to dedicate his or her time and effort to help protect the network against fraud and bad actors for a reward.Marshals know about the subject, have worked in the industry and bring with them vast quantities of experience in that particular field. Once chosen, marshals are tasked with examining the evidence before voting in an A/B manner for the party they believe correct. At this point, the losing party has the ability to appeal should they feel so inclined.
To become a marshal, you need to stake at least 1,000 PTM tokens in the vault contract. After the staking, you will need to open a proposal on why the community should vote and accept you as a marshal. If the majority of the votes approve your position as a marshal, you will be automatically approved on the marshal contract. If you are voted against as a marshal, you can simply stake PTM tokens and get rewarded. The more PTM they deposit, the more likely they will be chosen to arbitrate.
Marshals will be rewarded from the fee charged for the dispute resolution and the commission against their DeFi holdings.
