In this session of the Cardano Developer Office Hours, Satya Ranjan, Lead Blockchain Architect at the Cardano Foundation, presents Yaci Store 2.0.0 and its role in advancing the next generation of Cardano indexing infrastructure. He explores its architectural improvements, performance enhancements, hoe its developed for building data-intensive applications, new features such as governance support, and more.
In this session of the Cardano Developer Office Hours, Santiago walks through SuperNode by TxPipe, explaining how it works, the infrastructure challenges it addresses for builders and operators, and why modular, reliable infrastructure is becoming essential for the next generation of Cardano applications. He explores deployment optimizations, ecosystem pain points, benefits for developers and stake pool operators, and more.
In this session of the Cardano Developer Office Hours, Giovanni Gargiulo introduces uplc.link, a proposal focused on enabling verifiable and transparent smart contracts on Cardano. He explores why contract verification matters, how uplc.link works, its core design concepts and integration points, and what it could unlock for developer tooling, improving trust, auditability, and long-term maintainability of on-chain code, and more.
In this session of the Cardano Developer Office Hours, Thomas Kammerlocher and Fergal O’Connor present CIP-170, a proposal introducing KERI-backed metadata attestations for Cardano, and explore its practical implementation within Reeve. They examine the motivation behind the proposal, why KERI is well suited for decentralized identity and metadata integrity, the design principles shaping CIP-170, real-world implementation details in Reeve, and how these attestations enable verifiable, tamper-resistant metadata workflows, and more.
In this session of the Cardano Developer Office Hours, Karsten Siebert introduces Chimera, a Layer 2 solution focused on payments and negotiation for individuals and businesses building on Cardano. He explores the motivation behind the project, its current architecture and future direction, and how Chimera enables efficient off-chain coordination, flexible payment flows, practical real-world use cases aligned with Cardano’s design principles, implementation considerations, and more.
In this session of the Cardano Developer Office Hours, Darlisa Consoni hosts the final session of the year, featuring a research presentation by Dr. Yuzhe Zhang on stake-proportional voting power in blockchain governance, with a focus on Project Catalyst and the future design of Cardano governance. She explores how large stakeholders can unintentionally dominate outcomes, the mathematical limits of perfectly fair deterministic systems, quota adjustments, participation dynamics, governance trade-offs, and more.
In this session of the Cardano Developer Office Hours, George Flerovsky is joined by Peter Dragos and Ilia Rodionov for a deep dive into Hydrozoa, a lightweight state channel protocol built for efficient Layer 2 execution on Cardano. They explore how Hydrozoa streamlines off-chain coordination into simple, low-cost Layer 1 multi-signature transactions, enabling fast fund movement, flexible participation models, rule-based recovery guarantees, comparisons with Hydra, L2 ledger events, deposit and settlement flows, and more.
In this session of the Cardano Developer Office Hours, Raul Rosa and Matteo Coppola explore two key topics shaping the Cardano developer ecosystem: decentralized oracles and sponsored transactions, also known as Babel fees. They compare oracle architectures such as Charlie3, Artifacx, and Fluid Tokens’ proxy model, examine how these designs influence smart contract development, and introduce Aquarium, an open-source protocol enabling users to pay fees in custom tokens instead of ADA, covering UTXO trade-offs, fee abstraction, and more.
In this session of the Cardano Developer Office Hours, Fabian Bormann and Max Grützmacher share the latest progress on improving wallet connections across the Cardano ecosystem. They explore new connection flows, deep-linking with CIP-158, early design considerations behind CIP-144, and how updated standards and tools aim to deliver smoother mobile and desktop interactions, more consistent dApp–wallet communication, lessons from CIP-45 adoption challenges, PeerJS-based desktop-to-mobile flows, and more.
In this session of the Cardano Developer Office Hours, Giovanni Gargiulo introduces CIP-113, a proposal that brings programmable tokens to Cardano through a powerful and flexible new standard. He explores how CIP-113 enables advanced token logic, on-chain rule enforcement, and secure state transitions, unlocking enterprise-grade assets, compliance workflows, and next-generation dApps, while explaining its core design, practical use cases, and why programmable tokens matter for builders, and more.
