At Kleros we are building a blockchain-based, crowdsourced dispute resolution platform. An essential part of the mechanism design is the native pinakion token (PNK).

For each dispute that is arbitrated by Kleros, some number of jurors are required. A jury as small as three people may provide an initial ruling of a dispute. Then if one of the parties decides to appeal the ruling, the number of jurors in subsequent rounds increases.

PNK holders can stake their token in a Kleros court to indicate their availability to serve as jurors.
