What the Byron reboot means for Cardano

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…

Enter the Hydra: scaling distributed ledgers, the evidence-based way

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…

Community and stake pool reactions to the Shelley Incentivized Testnet

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…

New Cardano node, explorer backend, and web API released

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…
