Input Output Global (IOG)

Input Output Global (IOG) is a world-leading blockchain research and engineering company dedicated to building a sustainable Web3 ecosystem through pioneering research and cutting-edge innovation. Founded in 2015 by Charles Hoskinson, IOG has evolved from a pure research organization into a comprehensive venture studio and systems company that is rethinking how the world connects, transacts, and collaborates.

Core Business Model

IOG operates through three integrated pillars:

Blockchain Development: IOG is the founding development organization behind Cardano, the first blockchain rooted in peer-reviewed science, and Midnight, a fourth-generation privacy blockchain. The company has produced over 250 peer-reviewed research papers and maintains partnerships with leading global universities including Stanford, Carnegie Mellon, University of Edinburgh, and Tokyo Institute of Technology.

Venture Studio: The IOG Venture Studio supports founders through every stage of development, from initial concept to independent spinout. The studio provides research, governance, incentives, and systems design expertise, backed by a modular Launchpad infrastructure offering legal frameworks, compliance support, and integration pathways into Cardano and Midnight ecosystems.

Research Division: Input Output Research (IOR) is IOG's dedicated R&D division pioneering foundational and applied research in cryptography, distributed systems, and formal methods. Using an evidence-based methodology rooted in peer-reviewed science and formal specification, IOR builds high-assurance protocols using Software Readiness Levels (SRLs) to ensure a clear path from conceptual modeling to implementation.

Key Strengths

IOG's unique approach combines academic rigor with practical engineering. The company has published 250+ peer-reviewed papers with 10,000+ industry citations and works with 15+ leading research partners globally. Their research spans the full blockchain stack including cryptography (zero-knowledge proofs, post-quantum cryptography), consensus mechanisms (Ouroboros family of protocols), formal verification, distributed systems, network optimization, game theory, economics, and policy.

The company's 600+ team members across 50+ countries bring together world-class researchers, engineers, and entrepreneurs. This global presence enables IOG to tackle complex challenges in decentralization, security, and scalability while creating open knowledge that benefits the entire blockchain ecosystem.

Notable Projects and Ecosystems

IOG has built two major blockchain ecosystems:

Cardano Ecosystem: Launched in 2017, Cardano has evolved through Byron, Shelley, Goguen, and Basho phases to become a mature layer-1 blockchain with decentralized governance. The ecosystem includes products like Lace (light wallet platform), Blockfrost (Cardano API platform), Catalyst (project voting and funding), Identus (decentralized identity), Djed (stablecoin), and Bitcoin DeFi (Bitcoin-Cardano bridge).

Midnight Ecosystem: Launched in 2025, Midnight is a zero-knowledge layer-1 blockchain designed for programmable privacy. It introduces a rational privacy model where openness and confidentiality coexist through public and private states, enabling developers and institutions to control data disclosure while maintaining compliance.

Why Choose IOG

IOG stands out through its commitment to peer-reviewed research, formal methods, and long-term thinking. Unlike companies that prioritize speed over security, IOG invests in rigorous academic research and mathematical proofs to ensure protocols are secure, scalable, and built to last. Their partnerships with Hyperledger Foundation and leading universities demonstrate their commitment to open-source innovation and industry standards.

The company's venture studio model provides entrepreneurs with unparalleled access to cutting-edge research, proven infrastructure, and strategic guidance to build ventures with sustainable foundations. From legal entity setup to token economics modeling to regulatory compliance, IOG's Launchpad infrastructure accelerates time-to-market while maintaining the highest standards of security and integrity.

With features like cybernetic intelligence for risk modeling and economic simulation, modular execution frameworks, and integration into mature blockchain ecosystems, IOG offers a comprehensive platform for building next-generation decentralized systems that restore trust and empower individuals worldwide.
