Cardano features some of the most innovative elements of blockchain technology: Hydra and Mithril, for example – layer 2 solutions designed to enhance scalability. Or Cardano’s proof-of-stake consensus protocol, Ouroboros, whose various 'flavors' (Genesis, Praos, Peras, etc) ensure that the blockchain remains efficient and secure even under adversarial conditions.

But there's…

Professor Aggelos Kiayias FRSE, Input Output (IO)’s chief scientist, chair in cybersecurity and privacy, and director of the Blockchain Technology Laboratory at the University of Edinburgh, has been awarded the 2024 BCS Lovelace Medal.

This award recognizes his transformative contributions to the theory and practice of cybersecurity and cryptography, with his work leading to new…

Input | Output (IO) was founded on the promise of being a catalyst for change—to transform global systems for everyone, everywhere, and to champion products that are built ethically from the outset. Since our early days in 2017, these principles have remained constant. Through hard lessons, trials, triumphs, and everything in between, we’ve embraced the guiding principle that…

The previous blog post discussed formal methods and their role in blockchain development.

Building on the importance of formal methods, Input | Output (IO) demonstrates their practical application through real-world examples. By integrating these techniques into the development process, IO ensures robust, high-assurance systems that drive innovation in blockchain technology.
