The worker proposal contract is still being designed, but the idea is when a WP is submitted to the custodians for approval, it includes an EOS account name as the arbitrator. Custodians will factor that in to their decision to approve or not (is that person an expert in the subject matter, are they trusted by the community, etc). By default the arbitrator would just be the custodian board, but that gives them two seats and the two of three mutisig escrow contract. The point of the arbitrator is to ensure the DAC and service entity avoid legal drama if someone feels they should get paid as promised but a new custodian board is elected and refuses to pay.

Thank you for the reply. The arbitration role is very important and in bidding portals etc where escrow feature is currently used the release often ends up in disputes.

The governance and voting based on the Blockchain technology sounds like an important application of the technology. Ie as important as disruptive as the currency use case.
