In this interview, Kristian Portz, co-founder of Masumi Network, explains how the platform builds infrastructure for AI agents to work together, make decisions, and handle payments autonomously - while staying secure and compliant with European regulations. Built on the Cardano blockchain, Masumi creates transparent systems where agents interact without human input. Portz highlights real-world use cases in finance and healthcare and considers how AI agents might shape future governance, marking a shift in technology collaboration. Sounds Exciting? Well..let’s dive right in!

In this session of the Cardano Developer Office Hours, the team presents PoP (Proof of Provenance), a project to decentralize open-source development on Cardano. They cover risks of centralized infrastructure, using Cardano for verifiable software metadata, Merkle trees, and on-chain tracking. A live demo shows PoP in action. Use cases include secure versioning, on-chain test management, SPOs as decentralized oracles, and decentralized package tools.

Alex Nemish and Oleksii Khodakivskyi from Lantr introduce Scalus, a smart contract framework built with Scala 3. They walk through the vision, roadmap, and show how it simplifies development on Cardano, including a live demo of a payment splitter contract. This session is ideal for devs exploring new tools to build on Cardano.

In this interview, Rusty, also known as fallen-icarus on X, shares his vision for a truly decentralized financial system. He discusses the flaws in today’s DeFi models, which often rely on centralized mechanisms, and explains why a shift to P2P DeFi is necessary. Rusty breaks down key concepts like liquidity sharing, UTXO contention, and free-market solutions, offering a fresh perspective on making DeFi more scalable, efficient, and accessible. To learn more about the P2P DeFi solution Rusty proposes, check out the full interview below.

Giovanni Gargiulo, Senior Software Engineer at the Cardano Foundation, shares how ecosystem engineering supports Cardano’s growth. The session covers DevOps practices behind scalability, security, and uptime, along with challenges of running decentralized infrastructure. Giovanni also touches on infrastructure evolution, global adoption, and what’s ahead for Cardano engineering.

Satya Ranjan, Lead Blockchain Architect at the Cardano Foundation, presents Java tools for building on Cardano. The session covers cardano-client-lib, writing off-chain code, building transactions, and integrating governance and staking. Satya also demos Yaci DevKit for local dev environments, Yaci Store for indexing, and shows how to build lightweight apps using tailored data. Ideal for developers and exchanges exploring Java’s role in Cardano infrastructure.

This installment of the Cardano Developer Office Hours explores Reeve, a next-generation accountability tool for delivering tamper-proof and transparent financial insights. Reeve integrates traditional accounting systems with blockchain technology, ensuring transparency, immutability, and security for financial records. Built on Cardano, the platform offers a decentralized approach to financial data management. Designed for accountants, auditors, non-profits, and enterprises, Reeve helps streamline audits, improve efficiency, and build trust in financial processes. The session provides an overview of the project, its architecture, and current development.

This installment of the Cardano Developer Office Hours explores the Cosmos-Cardano Inter-Blockchain Communication (IBC) bridge project. The session provides an overview of the architecture, current development, and key components driving the project. Topics include the IBC protocol, blockchain interoperability, and the integration of Cosmos SDK with Cardano. A live demo showcases how to send messages between the Cosmos network and a local Cardano node. The session also covers real-world use cases like token transfers, cross-chain swaps, and more.

This 13th installment of the Cardano Developer Office Hours is presented by Thomas Kammerlocher, Senior Full Stack Developer at the Cardano Foundation. Thomas discusses the Java implementation of Rosetta, a tool developed by Coinbase for exchanges to integrate with Cardano. Rosetta simplifies multi-chain support with its blockchain-agnostic API, and the transition from TypeScript to Java enhances performance and reduces resource consumption. Upcoming updates include support for staking rewards tracking, off-chain data integration, and more improvements to scalability and efficiency.

In this interview, Raul Antonio, CTO of FluidTokens, shares with us how the platform is unlocking liquidity within the Cardano ecosystem. FluidTokens offers a unique way for users to access instant, unspendable loans by leveraging much of Cardano’s staking mechanism, providing both security and convenience for borrowers and lenders.

Did you know FluidTokens is also paving the way for Bitcoin users to interact with Cardano through Bitcoin DeFi? Well, Raul also touches on this. He explains how the platform is building exciting partnerships, like their collaboration with Minswap to develop a DEX for programmable tokens. He also gives us a glimpse into the platform’s future plans, including cross-chain integration and ZK P2P loans.
