abstract
Where is the value of DAO? What are the advantages over traditional forms of organizational management? This is a topic that many people ask. V God believes that the value of DAO lies in that through mechanism design and technical support, it can promote people to cooperate to a greater extent instead of betraying each other. It can promote multi-win to a greater extent, rather than seeking to maximize the interests of one party. The types of benefits are not limited to money, but also include public welfare.
Propose the concept of super-rationality, through mechanism design and technical support, eliminate people's asymmetry of information; eliminate people's differences in information processing capabilities; evaluate people in cooperation purely from the dimensions of morality and integrity; and fully protect ethical People; Encourage people to be kind, eliminate untrustworthy people, and form a circle of trust.
At present, centralized organizations and the Internet have made some improvements in information disclosure and information symmetry, but they are still very insufficient, and provide some people with stronger mind-reading (seeing through other people's cards) and deception capabilities. This type of cooperation model needs to be improved from the perspective of further enhancing transparency and incentives.
Limitations of DAO: Public welfare issues may not be within the scope of benefit, because the mechanism does not solve the problem of large-scale multi-party incentives, and some untrustworthy people cannot be excluded. But as the complexity of society continues to increase, DAO may make some value.

Translator's point of view
Combined with the previous paper "On the Chimney (Separated Island)", we can see that the DAO in V God's eyes is a combination of cooperation mechanism, information disclosure, forecasting, decision-making management and other elements, and its essential purpose is to encourage people to cooperate , to maximize the interests of multiple parties.
At present, some projects dedicated to doing things generally reflect that the voting participation rate of users is low. How to motivate users to participate is a very challenging topic. But if the user voting participation rate is high, will there be good benefits? Still have to return to the essence. The original intention of DAO is to encourage people to participate, encourage cooperation, and maximize benefits. What counts as effective participation and cooperation? It should still be considered in terms of contributing ideas, technologies, financial support, and execution of activities that contribute to ecological development. Then for various roles such as thought and technology leaders, technicians, operators, investors, users, other project parties, regulators, etc., we should maintain an open and cooperative attitude, and formulate differentiated cooperation models and incentives based on priorities Model. If you simply think that you don’t need ideas input, only financial support is needed, or you stick to a technical route and ignore more innovations, then the project’s way forward will have less chance of winning.

A common question many people have about the concept of a DAO (Decentralized Autonomous Organization) in the crypto 2.0 space is: what are the benefits of a DAO? If an organization's management and operations are tied to fixed code on a public blockchain, what are the fundamental advantages over the traditional route? What are the advantages of blockchain contracts over ordinary shareholder agreements? Especially even if transparent governance and guaranteed non-evil governance are supported, individual organizations open core source code and weaken themselves, and competitors can see their plans while competing behind closed doors. What is their motivation for doing so?

There are many ways to answer this question. Specifically for nonprofits that have a clear commitment to philanthropy, they lack personal incentives but work to improve the world without receiving monetary gain themselves. For a private company, if everyone else can bring their own information and intelligence into the computation, other things being equal, the governance algorithm will work better based on the information theory argument, because according to the established In fact, by increasing the amount of data compared to adjusting the algorithm, the effect can be greatly improved. In this article, however, we will take a different, but more specific, route to analysis.

What is hyperrationality?

In game theory and economics, it is widely accepted that different ways of cooperating lead to different outcomes, and that individuals can act in one of two ways, mutually "cooperating" or "defecting" with each other. Everyone is better off if everyone cooperates, but everyone is better off defecting no matter what others do. As a result the story happens and everyone ends up betraying so people's individual rationality leads to the worst collective outcome. The most common example is the famous prisoner's dilemma game. Since many readers may have already seen the Prisoner's Dilemma, for added interest, I propose Eliezer Yudkowsky's even crazier version of the game:

From a pragmatic and moral point of view, our choice to betray is justified, and a paper clip in another universe cannot possibly be worth a billion lives. From an AI perspective, betrayal would result in an extra paper clip whose code assigns exactly zero value to a human life. Therefore, it will betray. However, this leads to results that are obviously worse for both parties than the benefits of human and artificial intelligence cooperation. However, if the artificial intelligence is to cooperate, we can save more lives by defecting, and the same is true for artificial intelligence. In the real world, many small-scale two-party prisoner's dilemmas are resolved through trade mechanisms and legal systems that enforce contracts and laws, in which case if there exists a God with absolute power over both universes, but only Concerned about keeping a priority agreement, humans and AI can enter into cooperative agreements and ask God to prevent both parties from betraying at the same time. When there is no ability to pre-contract, the law punishes unilateral treachery.

Of course in many situations, people sometimes act ethically and cooperate even when it is detrimental to their personal situation. But why do they do it? We were created by evolution, and evolution is usually a rather selfish optimizer. There are many explanations, one we will focus on is the concept of hyperrationality.

hyperrational considerations

The following explanation of virtue, provided by David Friedman:

There are two observations about humans. The first is that there is a substantial connection between what is happening inside and outside their heads. Through facial expressions, body posture and various other signs, we can understand at least part of our friends' thoughts and emotions; the second is that our intelligence is limited, and we cannot consider all options in the time to make a decision. In computing terms, we are machines of limited computing power operating in real time. Suppose I want people to believe that I have certain characteristics, that I am honest, kind, and helpful to my friends. If I actually had these traits, it would be easy to project them, and I would just do and say what seemed natural and pay less attention to how I appeared to outside observers. They would observe my words, actions, facial expressions and draw reasonably accurate conclusions. However, suppose I don't have these characteristics. I'm (for example) dishonest. I generally act honestly because it is usually in my interest to act honestly, but I am always willing to make an exception if I can benefit from it. Now, in many practical decisions, I have to do double counting. First, I have to decide how to act, for example, whether this is a good opportunity to steal without getting caught. Second, I have to decide how I'm going to think and act, what look will be on my face, will I be happy or sad, if I'm really who I'm pretending to be. If you need your computer to do twice as many calculations, it will be slower. The same is true for humans. Most of us are not very good liars. If this argument is correct, it means that if I was really honest (and kind and...), I would probably be better off with less material conditions, e.g., have a higher income, And not that I'm just pretending to be, simply because real virtue speaks louder than pretended virtue. So, if I'm a narrowly selfish person, I might try to make myself a better person, more virtuous in those ways that other people value, for purely selfish reasons. The final stage of the debate is the observation that we can be better, by ourselves, by our parents, and maybe even by our genes. People can and do try to train themselves to develop good habits, including habits of automatically telling the truth, not stealing, and being kind to friends. With enough training, these habits become taste, and doing "bad" things makes one uncomfortable, even if no one is watching, so one doesn't do them. After a while, a person doesn't even have to decide not to. You could describe this process as synthetic conscience. Essentially, it's hard to convincingly pretend to be virtuous while being greedy as long as you can get away with it, so it makes more sense for you to actually be virtuous. Much ancient philosophy followed similar reasoning, viewing virtue as a cultivated habit. David Friedman just does us the usual service of economists and translates intuition into a more analyzable formalism. Now, let's push this experience a step further. In short, the key point here is that humans are public agents, and every second we act, we basically indirectly expose parts of our source code. If we really intend to act nice we act one way, if we just pretend to be nice but actually intend to act immediately when our friend is vulnerable we act differently when others usually Will take note of this. This seems to be a disadvantage. However, it allows a kind of cooperation not possible with the simple game-theoretic agents described above. Suppose two agents, A and B, both have the ability to "read" whether the other is "good" with some degree of accuracy, and are playing a symmetric prisoner's dilemma. In this case, the agent can adopt the following strategy, which we assume is a benign strategy:

1. Try to determine if the other person is benign.

2. The other party is moral and cooperative.

Both parties will cooperate and get greater rewards. If a good person comes into contact with a non-good person, the good person will betray. In all cases, therefore, the virtuous agent earns at least as much as, but often better, than the unethical agent. This is the nature of hyperrationality.

As unnatural as this tactic may seem, human culture has some ingrained enforcement mechanisms, especially in relation to untrustworthy agents who work hard to make themselves less readable, see the common adage that you should never People who don't drink should be trusted. Of course, there is a class of people who can convincingly pretend to be friendly but actually plan betrayal every moment, and these are called sociopaths, and they can be the main flaw in this system that humans have built.

Centralized manual control organization...

This kind of hyperrational cooperation can be said to be an important cornerstone of human cooperation in the past 10,000 years, even though these simple market incentives may lead to defection, but people can also be honest with each other. However, perhaps a by-product of modern large centralized organizations giving people the ability to read minds and effectively deceive others makes this kind of cooperation more difficult. Most people in modern civilization reap the benefits, but they indirectly fund some people in some 3rd world countries dumping toxic waste into rivers to make cheaper products. Yet, we don't even realize that we are indirectly involved in this betrayal, that the company does the dirty work for us. The market is so powerful that it can even arbitrage our own morality, handing over the dirtiest and most unsavory tasks to those willing to sell their consciences at the lowest cost, and effectively keeping them hidden. Companies can have their marketing department create a smiling face as their public image, and have a completely different department sweet-talk potential customers. This second department may not even know that the department producing the product is more immoral and less beautiful than them.

Arguably, a greater degree of transparency offers a solution. Individuals are moderately open, and the current centralized organization is less open. Organizations that continuously and randomly release information to the left, right, and center of the world are more likely to be open than individuals. Imagine a world where if you even started thinking about how to cheat on your friend, business partner or spouse, there was a 1% chance that the left side of your hippocampus would rebel and send a full transcript of your thoughts to your intended victim in exchange for $7,500 in rewards, it's like a governance dashboard for open organizations.

This is essentially a restatement of the founding ideology behind WikiLeaks, which has been superficially furthered recently by the emergence of a motivated WikiLeaks alternative, slur.io. However, the founding of WikiLeaks was murky, and the murkiness of centralized organizations will remain. Perhaps incentives, coupled with similar predictive mechanisms for people to profit from employer misconduct, will open the floodgates for greater transparency, but in the meantime we can go a different route: provide a way for organizations themselves to voluntarily and thoroughly , open, hyper-rational to an unprecedented degree.

. . . and DAOs

DAOs as a concept are unique in that their governance algorithms are not only public, but in fact fully public. That is to say, even in a transparent centralized organization, outsiders can only roughly understand the temperament of the organization, but with DAO, outsiders can actually see the entire source code of the organization. Right now, they can't see the "source code" of the people behind the DAO, but there are ways to write the source code of the DAO so that no matter who the participants are, it's heavily oriented towards a specific goal. A futarchy organization that maximizes average human lifespan will be very different from a futarchy organization that maximizes paperclip production, even if the exact same people are running it. So not only does the organization make it clear to everyone else when everyone starts to cheat, but even the "mind" of the organization cannot possibly cheat.

What market failure problems that conventional cooperation cannot solve can be solved by ultra-rational cooperation? Unfortunately, issues of public affairs may be outside the scope; none of the mechanisms described here address large-scale multiparty incentives. In this model, organizations make themselves decentralized and public in order to make others trust them more, so organizations that fail to do so are excluded from the economic benefits of this "circle of trust". For public goods, the root of the problem is that no one can be excluded from benefiting, so the strategy fails. But anything that has to do with information asymmetry falls within that spectrum, and it's a wide range indeed, and as society becomes more complex, deception in many ways will become easier and more Difficult to regulate or even understand, the modern financial system is just one example. Perhaps the real promise (if there is one) of DAOs is to help in this regard.
