The Generic Marketplace Vision

Eighteen Months and a Million Dollars: Part 8

Excerpts from the Whitepaper

Key Takeaways

• Compute alone isn't enough: a marketplace for compute, storage, and bandwidth together is worth far more
• Inspired by compositional game theory: treat mechanisms as composable building blocks, with explicit interfaces
• Decentralized vehicle routing: in some settings, coalition formation + credible commitments can push the Price of Anarchy toward 1
• Coalition formation with carbon optimization: minimize emissions while completing all compute jobs
• Agents will create their own languages when negotiating. Synthetic assets will emerge as agents encounter limitations of real-world assets.
• The trajectory: multi-agent systems operating in multi-token economies, a self-improving cybernetic system guided by market forces

Beyond compute

In earlier posts, we said the same primitives that enable compute markets also enable other markets, like energy, storage, bandwidth, information, and real-world assets. We've spent the past several posts building up those primitives: Alkahest for exchange and commitment, verification for trust, collateral markets for economic guarantees, adversarial design for robustness, and tokenization for idle compute.

Now let's talk about what happens when markets start interacting with each other.

A marketplace for compute is not worth nearly as much as a marketplace for compute, storage, and bandwidth. The ability to have a job computed on one node, the corresponding result sent to a second node, and then stored on the second node for some period of time with proper incentives for each of the nodes involved is still quite difficult to do with most current distributed protocols, despite the relative simplicity of the task.

This difficulty is a consequence of fragmented design. Protocols that focus on compute expect developers to integrate with separate storage protocols and separate bandwidth solutions. Each comes with its own tokens, its own APIs, and its own trust models. The complexity barrier blocks adoption.

The integrated approach is different. Same infrastructure for compute, storage, bandwidth, and beyond. Same escrow contracts. Same collateral patterns. Same verification framework. Different validators and conditions for different asset types, but the same underlying architecture.

In this post, we'll sketch one line of theory that influenced how we think about this (compositional game theory), then walk through two examples, and then end with what we expect agents to create as these markets become composable.

Compositional game theory (as inspiration)

One source of inspiration is compositional game theory: a framework that applies category-theoretic concepts to game theory by composing games with explicit interfaces.

Traditional mechanism design treats each mechanism as a monolithic system requiring complete analysis from scratch. This limits complexity: designing a new mechanism means starting over. It limits reuse: proven mechanisms can't be easily combined with others.

Compositional game theory treats mechanisms as building blocks. Open games have defined inputs, outputs, and interfaces. Composition operators let you connect games together in a few ways: sequentially (outputs feed into inputs) and in parallel (games interact side-by-side), so the overall system is assembled from smaller pieces.

One useful consequence is that analysis can sometimes become compositional too: under the assumptions of the formalism, you can reason about parts and then lift those results to the whole.

We're not claiming compositional game theory "enables" every marketplace we care about. It's a perspective: define primitives with clean interfaces, then build complex mechanisms by composition, and validate the composite system with the right mixture of analysis and empirical testing.

Decentralized vehicle routing

Here's a concrete coordination example. It's less about "compositional markets" and more about coalition formation plus credible commitments: agents making enforceable agreements that reshape collective outcomes.

Imagine overlooking a city from above. Every agent is trying to get from point A to point B on a train, in a car, on a bike, or walking. Each agent accesses their favorite map application, is returned the shortest path, and follows it.

Now imagine overlooking the same city, but the agents can be coordinated via an optimization algorithm that minimizes the average travel time. The ratio of the average travel time in the selfish case to the optimized case is called the Price of Anarchy.

In stylized settings, if agents can form coalitions and use credible commitments to enforce agreements, the toolset exists to try to push the Price of Anarchy toward one.

The mechanism is intuitive. If my taking a different route makes your trip faster, you can pay me to do it. But for that agreement to work at scale, it has to be enforceable: payments need escrow, conditions need validators, and disputes need resolution. That's exactly the shape of a credible-commitment system.

The benefits are concrete: lower air pollution, less mental health stress from traffic, lower emissions, and higher productivity. The point isn't that vehicle routing is "a marketplace" in the narrow sense. It's that many collective coordination problems become tractable once agents can make, price, and enforce commitments.

This isn't a compute problem. It's a coordination problem solved through market mechanisms. The same primitives handle both.

Coalition formation with energy

Compute nodes forming coalitions can be modeled as a game where nodes gain some benefit (higher expected return, lower variance in returns) by joining together. These nodes might also want to incorporate energy into their decision-making.

Consider the objective function: minimize carbon emissions subject to all compute jobs getting done and all homes getting the energy they require. This needs consensus-based load balancing across compute providers, energy suppliers, and consumer demand.

Coalition formation depends on each node's resources, the resources of prospective coalition members, and the resources of other nodes in the environment. Nodes need to communicate with each other and have a sense of their expected payoff. The reinforcement learning primitives enable them to learn from their environments.

Multi-agent debate, an emerging trend in AI, extends this to LLMs. The literature on resource- and skill-based games has focused on traditional scenarios: corporate environments where workers and departments have different resources and skill sets. The literature can be extended to considering LLMs as resources, differentiated by their architectures, weights, and access to information.

What agents create

The future is autonomous. Most economic activity in the future will be undertaken by machines, yet most of our marketplaces are built for humans. The permissionless aspect of blockchain-based markets will dramatically expand the user base, and autonomous agents will be the primary users.

When agents are the users, the artifacts of markets change.

First, negotiation becomes native. Agents will negotiate with each other on behalf of human owners and institutions, and increasingly for their own objectives as they manage infrastructure directly. For many real-world assets, that negotiation will look like fixed schemas and protocols (JSON messages, typed offers, explicit constraints). For intents-based deals, language-model-based agents will negotiate in richer spaces that aren't fixed ahead of time.

Second, communication compresses. New languages emerging from agent interactions might sound strange, but it's already happened in controlled settings: when neural networks are trained to communicate efficiently with each other, they develop protocols that optimize for bandwidth and coordination, not human interpretability.

Third, assets generalize. Synthetic assets will emerge as agents negotiate over real-world assets and encounter their limitations, just as humans did. Derivatives, futures, and options emerged to manage risk and express complex economic intentions. Agents facing the same constraints will create their own abstractions.

The trajectory of blockchains and cryptocurrencies is trending towards multi-agent systems operating in multi-token economies. It is not only the tokenization of real-world assets that pushes this trend, but on a larger scale, the separation of concerns facilitated by having multiple tokens representing different asset types.

The cybernetic system

Generalized marketplaces provide agents with the substrate on which to trade the very physical components that constitute them. The reinforcement learning primitives discussed in our first post provide agents with an understanding of what they are and what their role is.

Combining this self-awareness and the ability to engage in economic interactions over the physical components they are composed of provides a foundation for a decentralized collective machine intelligence which can guide itself through market forces towards a self-improving cybernetic system.

This is the vision: not a single AI, but a distributed system of agents coordinating through markets. Each agent optimizes its own utility. The market aggregates those individual optimizations into collective behavior. The system improves as agents learn, as markets mature, and as better mechanisms are discovered.

Out of these multi-agent systems will emerge collective intelligence capable of achieving far more than is possible with current technologies. The steady improvements in AI models, computational power, and networking are such that humanity is on the cusp of decades of theory stowed away in AI and game theory journals being rapidly implemented in practice.

What this means for you

If you're building applications that touch multiple resource types (compute + storage, bandwidth + latency, energy + carbon), the integrated architecture eliminates the integration burden. One set of contracts, one collateral framework, one verification layer.

If you're researching multi-agent coordination, compositional game theory is a useful lens for modular mechanism design: define interfaces, compose parts, and be explicit about assumptions.

If you're thinking about the long term, the trajectory is clear: more agents, more markets, more composition. The infrastructure being built now determines what becomes possible later.

Next in the series

We've covered the full vision: from primitives to verification to adversarial design to economics to market composition. In our final post, we'll bring it back to the practical: what can you build today?
