Obviously, the main selling point of DACs is that they are decentralized and autonomous on a protocol level. However, not everything can be implemented in a smart contract on the protocol level. One thing holding back the creation of some DACs is the need for trusted third party services. I believe DPoS and its delegates is a great solution for smart contracts that would require trusted third parties, meanwhile having benefits over current centralized solutions in terms of efficiency, fees, provably fairness, and others depending on the industry. Delegates would make trusted third party implementation into DACs manageable due to the numbers involved with them (trusting 101 people instead of one or a few people), and the fact that they could be voted out of power if one misbehaves or they collude in a nefarious manner.
Even with giving delegates more trusted roles and the extra work it would take and cost the DAC, I think we could still automate enough of it to where we could compete in a big way with some centralized behemoths through lower fees (IE. Ebay and Pokerstars), provably fairness (IE. Pokerstars), and other ways depending on the industry. I have long stated that decentralized poker can be done this way. One of the things holding it back is the ability to combat collusion, but I believe it can be done as efficiently as centralized services with slight centralization of the DAC. I am certain this is a non-issue, it is just a matter of making slight sacrifices to decentralization. The recent conversations about Open Bazaar and Ebay also made me think of it again, as arbitrators will be needed in that industry as well.
Here are a few ways I can think of that delegates can be used in this manner. Don't take this as a complete list because there are many possibilities of this, most of which I will not be able to think of off the top of my head. These are the use cases that immediately come to mind.Arbitration
Decentralized Marketplaces - IE. Escrow - Abritration of disputes via multi-signature addresses.
Decentralized Poker - IE. - Policing Collusion and Bots - Confiscating funds from nefarious actors and giving them back to those that were cheated through the use of multi-signature addresses.Moderation
"Legal" Decentralized Marketplaces - IE. Removing illegal items that are for sale in the marketplace
Decentralized Poker - IE. Policing Collusion and Bots - The detection of nefarious activity and investigation into players that have been reported.Services
Decentralized Exchanges - IE. Multi-Token Decentralized Exchanges - Each delegate runs both a Bitcoin and BTSX client allowing exchange from one cryptocurrency/bitasset to another cryptocurrency in a sufficiently trust-less manner via multi-signature addresses.
Again.. I know that the appeal of DACs are the removal of trusted third parties, but in some cases they cannot be done away with. DPoS itself is inherently managed centralization, along with BTSX delegate price feeds, why not expand the roles of delegates beyond simply maintaining an updated client to expand DACs other industries?
