Blockchain technology has evolved rapidly over the past decade, and few organizations have contributed as significantly to its academic and technical foundation as Input Output Hong Kong (IOHK). Founded in 2015 by Charles Hoskinson, a co-founder of Ethereum, and Jeremy Wood, IOHK operates as a world-class engineering firm dedicated to advancing peer-to-peer financial systems through rigorous research and open-source development.
At its core, IOHK is driven by a mission to create accessible financial services for everyone—especially the unbanked and underbanked—by leveraging blockchain’s decentralized architecture. Rather than chasing short-term trends, the company emphasizes peer-reviewed research, formal methods, and long-term sustainability in building next-generation blockchain platforms.
The Science-First Approach to Blockchain Development
Unlike many blockchain firms that prioritize speed-to-market, IOHK adopts a scientific philosophy in its development process. Every protocol or system undergoes extensive academic scrutiny before implementation. This approach ensures robustness, security, and scalability—three pillars critical to real-world adoption.
The team collaborates closely with leading universities such as the University of Edinburgh, Tokyo Institute of Technology, and Lancaster University to conduct cutting-edge research in cryptography and distributed systems. These partnerships enable IOHK to publish whitepapers on topics like proof-of-stake consensus, smart contract formalization, and universal composability—contributing valuable knowledge to the broader blockchain ecosystem.

Core Projects Driving Decentralization
IOHK has developed several high-impact blockchain initiatives, each serving a unique purpose in the decentralized landscape.
Cardano
Cardano stands as IOHK’s flagship project—a third-generation blockchain platform designed to overcome limitations in scalability, interoperability, and sustainability seen in earlier networks like Bitcoin and Ethereum. Built using Haskell, a functional programming language known for reliability, Cardano implements the Ouroboros proof-of-stake (PoS) protocol, the first provably secure PoS algorithm.
Ouroboros enables energy-efficient transaction validation while maintaining decentralization. With features like multi-asset support, native tokenization, and evolving governance through Voltaire, Cardano aims to become a self-sustaining ecosystem.
Daedalus Wallet
Daedalus is a full-node cryptocurrency wallet built exclusively for Cardano (ADA). As an open-source, extensible wallet, it gives users full control over their private keys and offers advanced security features such as encrypted backups and integration with hardware wallets like Ledger.
Its design philosophy centers around transparency and trustlessness—ensuring users don’t rely on third parties to manage funds.
Ethereum Classic (ETC)
IOHK played a pivotal role in supporting Ethereum Classic after the 2016 DAO fork. While Ethereum moved toward a revised history, ETC preserved the original chain’s immutability principle—"code is law." IOHK contributed engineering resources to enhance ETC’s protocol stability and long-term viability.
Scorex
Scorex is an open-source framework written in Scala that allows developers to experiment with custom blockchain architectures. It serves as a modular toolkit for prototyping consensus algorithms, networking layers, and state machines—accelerating R&D cycles across academia and industry.
Qeditas
Qeditas explores the intersection of blockchain and formal mathematics. Inspired by the QED Manifesto, this experimental project aims to create a decentralized repository of formally verified mathematical proofs. By anchoring proofs on-chain, Qeditas could help establish tamper-proof knowledge bases accessible globally.
RS|Coin
Developed in collaboration with Imperial College London, RS|Coin presents a scalable framework for central bank digital currencies (CBDCs). It introduces a hybrid model where a central authority oversees minting but delegates transaction validation to distributed nodes—balancing control with decentralization.
Symphony of Blockchains
A creative outreach initiative, Symphony turns blockchain data into immersive audiovisual experiences. By sonifying transaction flows and network activity, it makes abstract concepts tangible—ideal for education and public engagement.
Research That Shapes the Industry
IOHK doesn't just build products—it advances the theoretical foundations of blockchain itself. Its research division has published numerous influential papers, including:
- Linear Consistency for Proof-of-Stake Blockchains – Analyzes consistency models in PoS systems.
- Ouroboros-BFT: A Byzantine fault-tolerant protocol combining benefits of PBFT and PoS.
- Proof-of-Work Sidechains: Explores interoperability between PoW chains via two-way pegs.
- Formal Specification for a Cardano Wallet: Ensures correctness through mathematical modeling.
- An Ontology for Smart Contracts: Defines a structured framework for classifying contract types.
These publications reflect IOHK’s commitment to transparency and academic rigor—setting new standards for how blockchain projects should be engineered.
FAQ: Understanding IOHK’s Role in Blockchain Evolution
Q: What makes IOHK different from other blockchain companies?
A: IOHK combines deep academic research with practical engineering. Its protocols are peer-reviewed, mathematically proven, and built for long-term sustainability—not hype-driven launches.
Q: Is IOHK still involved with Cardano beyond 2020?
A: While IOHK’s initial development contract ended around 2020, it continues to contribute to Cardano’s evolution through ongoing research, upgrades (like Hydra for scaling), and community collaboration.
Q: Does IOHK develop private blockchains?
A: Yes. In addition to public chains like Cardano, IOHK builds permissioned blockchains tailored for government and enterprise use cases requiring privacy and regulatory compliance.
Q: How does IOHK ensure security in its platforms?
A: Through formal verification, extensive testing, third-party audits, and open-source transparency. Critical components are written in strongly typed functional languages like Haskell to minimize bugs.
Q: Can developers contribute to IOHK’s open-source projects?
A: Absolutely. Projects like Scorex, Daedalus, and Cardano node software welcome community contributions via GitHub. Documentation and developer tools are publicly available.
