Hydra is a layer-two scaling solution for the Cardano blockchain that aims to increase the transaction processing capacity of the network by allowing multiple heads or channels.
What Is Hydra (Cardano)?
How Does Hydra (Cardano) Work?
In the case of Hydra, multiple channels can be opened between participants, allowing for multiple transactions to be conducted in parallel. This is known as multi-headed scaling and is seen as a way to increase the overall transaction processing capacity of the network. The channels can be opened and closed as needed, and the transactions conducted within them are secure and private.
Hydra is considered isomorphic because transactions in a Hydra head, an off-chain ledger, share the same capabilities as the transactions running on the Cardano mainchain. The term “isomorphic” refers to the fact that there is a direct structural correspondence between transactions running on Cardano and those running in a Hydra head. This means that transactions in a Hydra head have the same form, shape and structure as transactions on the Cardano mainchain.
As a result, Hydra also supports any programming language that Cardano backs. This allows developers to construct transactions in Hydra using the same existing tooling they already use with Cardano.
What Is the Roadmap for Hydra (Cardano)?
Phase One was the research and development stage. During this phase, the Cardano team conducted research into the feasibility of the Hydra concept and developed the initial specifications for the solution.
Phase Two implemented a prototype. In this phase, the team built a working prototype of the Hydra solution to test and refine the technology.
In Phase Three, Hydra was integrated into Cardano.
