Scalability is the greatest challenge to blockchain adoption. By applying a principled, evidence-based approach, we have arrived at a solution for Cardano and networks similar to it: Hydra. Hydra is the culmination of extensive research, and a decisive step in enabling decentralized networks to securely scale to global requirements.

What is scalability and how do we measure it?

Scaling a distributed ledger system refers to the capability of providing high transaction throughput, low latency, and minimal storage per node. These properties have been repeatedly touted as critical for the successful deployment of blockchain protocols as part of real-world systems. In terms of throughput, the VISA network reportedly handles an average of 1,736 payment transactions per second (TPS) with the capability of handling up to 24,000 TPS and is frequently used as a baseline comparison. Transaction…

Education has always been a key part of IOHK’s strategy. Our mission is to grow our global community and business through the medium of education, and to share what we have learned. By claiming leadership in worldwide education on blockchain technology, we have the chance to shape the field for generations and to leave a lasting legacy.

A consistent theme from 2019 has been the…

The Incentivized Testnet (ITN) has been running since mid-December, and the results have produced some fascinating insights into stake pools and a steep learning curve for the blockchain engineers at IOHK, as well as the companies and individuals setting up stake pools, and ada owners. The strategy of using a fast development team writing in the Rust language to act as…

Today marks the culmination of considerable effort by the Cardano team: the release of a new Cardano Haskell implementation. This implementation consists of two main components: the Cardano Node and the Cardano Explorer Backend and Web API. Over the past 18 months, we’ve been building a new architectural foundation that will not only prepare us for the upcoming releases for…

The Shelley Incentivized Testnet is proving to be an incredible journey. Originally, we hoped for around 100 pools. As of today, we've reached over 1,000 registered and more than 670 active pools. Over 11.5B ada is now being staked on the testnet. The many improvements to performance have resulted in an increase in uptime – but there's still a way to go. We are not resting on…
