Hi Dana, some comments:

By nodes I assume you mean either economic agents or intelligent agents?

Yes, agents in the abstracts. They could be autonomous software or users acting on the network. The relevant properties of these agents are generally the same: they will amorally fulfill economic incentives.

it's not a stretch to believe that intelligent agents can be used to promote a global moral regime which most of us disagree with

I totally agree here. Just as people write software to exploit economic advantages found on a cryptocurrency-enabled network, users can also write benevolent software to counteract negative effects. For instance, if the Disney website is being DDoSed due to an ill-formulated prediction market, watchdog nodes could potentially reduce the economic incentives to do harm. It's an interesting problem with many facets, not the least of which is: it takes capital to undo harm, so where does this capital come from?

you create order in cyberspace according to the rules and norms selected by individuals.

Indeed! And for full disclosure, I am a citizen of Bitnation. I definitely think that consent-based citizenship in digital nations, DAOs, and other decentralized systems that permit membership is the way to go. To extend the national analogy, how does the system deal with large-scale decentralized behaviors between nations, which may not always align?

Smart contracts, dispute resolution, reputation systems, sites like this, or concepts like what is being worked on by team Bitnation, are all about solving problems.

Would love to learn more about the thinking here!
