Overview
The IOG Research Papers page is the official library of peer-reviewed academic papers from IOG (Input Output), one of the engineering organizations that builds Cardano. The site collects hundreds of papers covering cryptography, how distributed networks agree on what happened, smart contracts, game theory, and economics. Together, the papers make up one of the largest formal bodies of research in the blockchain world.
The library is the work of Input Output Research (IOR), a research division led by Chief Scientist Prof Aggelos Kiayias. IOR works across nine focus areas and partners with universities like Edinburgh, Stanford, Carnegie Mellon, and the Tokyo Institute of Technology1. The peer-review-first approach is what sets Cardano apart from most other blockchain projects: the core protocols are built on top of academic papers that other researchers have read, critiqued, and signed off on2.
The IOG Research Papers page is freely accessible, with no paywall or signup. Visitors can browse the full list or filter by topic, author, and category. For readers who want the formal basis behind Cardano's design, this is the source. For readers who just want to know whether the project's claims have been checked, this is the proof.
Key Features
-
Papers in serious academic venues. The library covers papers published at top-tier cryptography conferences, including CRYPTO, Financial Cryptography, Asiacrypt, and ACM CCS. The foundational Ouroboros paper alone has thousands of citations on Google Scholar3.
-
Nine research areas. The collection covers cryptography, consensus, formal verification and programming languages, software engineering, distributed systems, networks, game theory and incentive design, economics, and policy and regulation1.
-
The basis for Cardano's core infrastructure. Research underpins major parts of the network, including the Ouroboros consensus family, the Hydra scaling layer, the Mithril light client project, and the way Cardano records transactions2.
-
Open access for everyone. All papers are free to read. The site provides filters by topic, author, and category to help readers find the right paper quickly1.
-
A structured path from idea to product. IOR uses something called Software Readiness Levels to track an idea as it moves from early exploration through to a feature people can actually use1.
What to Expect
The IOG Research Papers page is a searchable collection organized by topic, author, and category. Visitors can browse the full library or filter to specific research areas like proof of stake (where ADA holders help secure the network instead of energy-hungry mining machines), blockchain theory, or cryptography. Each entry includes the paper title, the authors, the publication venue, and a link to the full text.
Beyond the paper listings, the site also publishes research videos covering topics like Ouroboros and the Leios scaling work, which are accessible through the news section. A companion page at iog.io/research describes IOR's overall approach, the universities it works with, and the active research streams. Researchers and academics interested in collaborating can reach out through a dedicated contact form on the site1.
The IOG Research Papers library is the main evidence base behind Cardano's research-first reputation. It gives readers a way to verify claims about the network's governance, scaling, and design without relying on marketing material. For anyone who wants to know whether the science holds up, the papers are right there to read.
