Reputation Arbitration: Building A Decentralized Reputation System For Arbitrators?

Under arbitration, the parties submit their disputes to an arbitral tribunal (or sole arbitrator) who rules on pre-hearing disputes, conducts the arbitration, and issues a binding award on the parties.  However, the desirability of arbitration as a dispute-resolution mechanism rests largely on the perception of the reputation of the arbitrators. On the one hand, the arbitrator has a reputational concern, in the sense that he/she wishes to appear competent, independent, and impartial to the parties. The reputational concern could stem from a desire to boost his/her prestige, his/her revenue, or his/her experience.  On the other hand, clients value arbitration when an independent, impartial, and correct decision is made.  Now, could a blockchain based reputation system be implemented for arbitration?
