This event is a series of open discussions on the WIP work of exploring practical implementations of cooperative AI. We specifically focus our discussion on concrete, approachable ways to study and realize commitments for cooperation. And our goal is to bring together facilitate discussions between pragmatic commitment device researchers and cooperative AI researchers to better map out the directions of this collaboration.
On a high level, we try to answer those two questions:
To answer those two big questions, we might want to breakdown, and ask easier brainstorming questions to sparkle our creativity. So, for example:

2a. Commitment Devices: Role, Limitations, and Trade-offs
Both crypto and cooperative AI have focused significantly on commitment devices, a decentralized way of implementing coordination. How does this study relate to the traditional way of implementing coordination via mediators/mechanism design
Rephrasing: What can blockchain and AI say that is new about coordination? Can you put them somewhere on the map of previous literature, or is there a difference in kind between what they enable and what was there before? Do they trivially solve problems that were considered "hard" previously?
1b. Blockchain and AI: Synergy and Value Proposition
What are the limitations around current studies and designs of the thesis of “blockchain as a commitment device”? Considering various approaches such as information design, game mining, principal-agent problem style payment, anti-mechanisms, darkdaos, and optimal credible auctions, how do we push things forward? What is lacking in crypto achieving this value proposition?
What are tangible steps to map insights from the literature onto "crypto-native" problems?
- Bottom-up approach: Find small examples, try to solve them using previous ideas/models
- Top-down approach: Survey of results/taxonomy and mapping each category to crypto-specific problems
What are we missing? What is a critical learning from the theory of commitments that is "folklore" in the field but has very practical applications that we should think about? (Im)possibility results, underexplored avenues…
4a. Practical Implementation of Cooperative AI
What are some robust ways to implement resolution of program equilibria? How could these solutions be realistically implemented for complex, economically meaningful applications?
The eBay "autobid" function allowed passive bidders to participate meaningfully, a bit like CFMMs with passive liquidity allow for liquidity providers to be "always on". The ability to deploy a program to act on your behalf seems to enable new economic activities. But do they scale well? Are program equilibria useful beyond the smaller examples of solving prisoner's dilemma? New results look at how they compose with one another, is there more to be said about composition? Is this the next problem to solve for PE?
2c. Commitment Devices: Role, Limitations, and Trade-offs
Commitments theoretically allow for optimal welfare in a game with a known structure. However, in practice, the game structure is often uncertain and dynamic. What do you think is the limit for commitments? How far can we push them, and should we push them?
Can commitments become stale? Are there meaningful ways to commit in a complex environment, where conditional strategies need to condition on many unseen things? Theory of commitment when you have incomplete information, e.g., you don't know the whole strategy set/you are learning?
3b. Balancing Different Coordination Mechanisms
Coordination can also be implemented via governance and policies. How do we balance this approach with the commitment devices approach? To what extent is human coordination insufficient?
Interesting! People do not care about the role that policies and regulations play for blockchain and AI (3c), but they care about how "softer" institutions such as governance and policies enable human coordination. My question: What do you see as coming first? Do commit devices extend softer institutions, or do they enable them in the first place?
How can the field of AI leverage the benefits of crypto-economic commitments to address coordination and alignment challenges? What might be the potential hurdles in implementing this approach? What are your expected biggest challenges? Are there any fundamental limitations you see in this approach?
