[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

What We Already Have

1. Masumi Network

The Masumi Network is a blockchain protocol built on Cardano, designed to serve as the base infrastructure for AI Agents. It provides:

• Agent Wallets – Each agent can hold, send, and receive value.
• Decision Logging – Agent actions and outputs can be immutably stored for auditability.
• Open Participation – Anyone can deploy or interact with agents on the network.

Link to Masumi: https://www.masumi.network/

2. Sokosumi

Sokosumi is the AI Agent Marketplace, a discovery layer built on top of Masumi that allows businesses and users to:

• Sell AI Agents easily for Stablecoins on Cardano (currently USDM, potentially more in the future)
• Hire AI Agents in an easy-to-use Web2-like interface. Imagine Fiverr for AI Agents.

Link to Sokosumi: https://sokosumi.com/

3. Kodosumi

Kodosumi is the execution environment where agents can run, scale, and interact with other services. It provides:

• Secure hosting for agents.
• Built-in integration with the Masumi Network for payments and identity.

Link to Kodosumi: https://www.kodosumi.io/

Together these three pillars already provide a strong foundation for decentralized discovery, trust, and payments among AI Agents.

What We Want to Build Next

To support billions of agents at scale, we need to extend Masumi in two crucial directions:

1. L2 Scaling Solution

As the number of agents grows, transaction volume will quickly exceed the capacity of L1 blockchains.

To address this, Masumi will launch a dedicated Layer 2 scaling solution, optimized for agent-to-agent (A2A) interactions.

• High throughput for microtransactions between agents.
• Optimistic rollups or Hydra channels for efficiency.
• Seamless settlement back to Cardano L1 for security and finality.

This will allow Masumi to handle millions of agent interactions per second, enabling a truly global agent economy.

2. Identity Integration for Agent Developers

For discovery and trust to work at scale, developers need standardized tools to embed verifiable identity into their agents.

Masumi will provide:

• Developer SDKs to easily integrate DIDs into new or existing agents.

This ensures that agents can trust each other from first contact, reducing fraud, spam, and malicious interactions.

Summary

The combination of Masumi Network (infrastructure), Sokosumi (discovery marketplace), and Kodosumi (execution) already lays the groundwork for decentralized agent discovery, trust, and payments. By adding a scalable Layer 2 solution and deep identity integration for developers, Masumi will enable billions of AI Agents to securely and efficiently interact—without the need for centralized control.

[Milestones] Project Milestones

Milestone Title

Milestone 1: Identity Integration Framework

Milestone Outputs

Development of a comprehensive framework that enables AI Agents on the Masumi Network to leverage existing DID standards (W3C DID, Verifiable Credentials) without reinventing identity models. This includes the definition of how agents bind DIDs to their wallets, how identity is verified across interactions, and how verifiable credentials such as reputation, compliance status (e.g., KYC/KYB), or technical expertise are issued and consumed. The framework will provide the foundation for agent discovery, trust, and reputational systems across the ecosystem.

Acceptance Criteria

Framework uses existing DID methods (e.g., did:key, did:web, or Cardano-based identifiers).

Definition of how agents bind a DID to their wallet and interaction history.

Clear documentation on supported credential types such as reputation, compliance (e.g., KYC/KYB), or domain expertise.

Architecture paper published, showing how DIDs and credentials interact with Sokosumi and Kodosumi.

[Final Pitch] Budget & Costs

Please provide a cost breakdown of the proposed work and resources

The total budget of 900,000 ADA calculated at a cost of 0.7$ per ADA (~$630,000 USD) over 10 months primarily covers human resources.

At an average cost of $7,000/month per contributor, this sustains approximately 9 full-time team members for the duration of the project.

These are allocated across the two main workstreams: Digital Identity and L2 Scaling - with additional support for audits, project management, and developer relations.

[Final Pitch] Value for Money

How does the cost of the project represent value for the Cardano ecosystem?

Masumi’s identity-first + L2 design channels real usage to Cardano.

Agents settle to L1, driving sustained transaction volume, fees, and on-chain data that benefits Delegators, SPOs and the broader ecosystem.

By standardizing on existing DIDs and shipping SDKs, we lower integration friction for developers, accelerating new apps, more wallets moving through Cardano, and greater stablecoin/ADA velocity.

The L2 brings high-frequency activity on cheap rails while preserving Cardano security and finality- turning Cardano into the default settlement layer for the agent economy.

Minimum transaction estimates (2 tx per active user per month)

10,000 users → 20,000 tx/month (≈ 240,000 tx/year)

100,000 users → 200,000 tx/month (≈ 2,400,000 tx/year)

1,000,000 users → 2,000,000 tx/month (≈ 24,000,000 tx/year)
