We’re building Oneiron SDK — open-source JVM-based Cardano Sidechain Development Kit. Our goal is to enable developers, already familiar with enterprise/web technologies, to create Cardano sidechains and applications quickly and easily.
“Oneiron” (Ancient Greek) — “Dream”. Our dream is to bring millions of developers to Cardano.
With Oneiron SDK, anyone will be able to create a sidechain node with a simple CLI command. Oneiron-built node will be able to join an existing sidechain (built with Oneiron SDK) or to create an entirely new Cardano sidechain.
We’re also aiming to create Oneiron Network — a Cardano sidechain built with our SDK, enabling developers to start building apps immediately (without necessarily running their own nodes), with a variety of programming languages.
The language runtime choice is designed to primarily target the massive enterprise/web developer audience.
The Oneiron smart-contract runtime will be JVM-based, so it will support languages like Java, Kotlin, Scala, Clojure, etc., as well as JavaScript, Python, Ruby. We also aim to include support for Wasm and PlutusCore in the future.
Oneiron Network will use the Cardano eUTXO accounting model and Ouroboros consensus protocol.
In the future, we also aim to include support for IBC Protocol to enable interoperability with the Cosmos Network and blockchains in the Cosmos ecosystem.
The scope of the current phase is to build the first approximation of our sidechain SDK, capable of creating single-node Cardano sidechains. Users will still be able to:
- easily install the SDK,
- create their own (single-node, but still real) Cardano sidechain, capable of running smart-contracts on a JVM-based language runtime,
- begin development in the language of their choice and run their apps on the sidechain.
Creating and/or joining multi-node sidechains will be a subject of a future development phase.
