Form and function

IOHK is building Cardano into a global financial and social operating system. This enormous task requires both quick iteration and absolute precision. It is why IOHK has chosen to combine the speed of agile development with high assurance code and formal methods. Fusing flexibility and formality led our engineers to pioneer this modern development philosophy.

Duncan Coutts has been an important guide on the road to the Cardano Shelley mainnet. Long time supporters of IOHK are likely familiar with his signature long hair, beard, and penchant for drinking tea while discussing decentralization in front of a white board. He recently sat down for an interview to discuss the upcoming Byron reboot, the Haskell Shelley testnet, and the…

The Daedalus team is opening up IOHK’s wallet testing program to ada owners. The aim is to seek the help of a broad range of people who can test – on a rolling basis – the latest interface features being readied for the next release version of Daedalus. This will be a fully-functioning version of the wallet, called Daedalus Flight, so you will be able to spend and receive ada…

The Byron reboot is a series of updates to multiple components of the Cardano network. Namely the Cardano node, but also the Cardano explorer, the wallet backend, and the Daedalus wallet itself. The first part of the Byron reboot – a totally new node implementation – has already been deployed to some relay nodes on the network, and the next few weeks will see core network nodes…

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…
