No brainer. Thank you for submitting. Just approved this one.

Do we really need a java SDK
And how is it different than a kotlin SDK; isn’t it the same thing?

Don’t take me wrong, @CryptoFish, I value all your contributions, but I’d like to see something build on top of existing stuff

# Zenon Java SDK - Accelerator-Z project proposal

**Description:**

Development of a Zenon SDK written for the standard Java compiler. Having a Java SDK will help us in on-boarding new developers, who in-turn will help expand the Zenon ecosystem.

**URL:** 
https://github.com/KingGorrin/znn_sdk_java/blob/main/az.md

**Team**:

The team consists out of one developer known under the handle @KingGorrin aka CryptoFish. I'm experienced with Java and I've got a complete understanding of the Zenon Dart SDK. In earlier work I've recently released 100% functional implementation of the Zenon .NET SDK. The details and work of the project can be found at https://github.com/KingGorrin/znn_sdk_csharp. The Zenon .NET SDK can be considered my PoW and commitment to the Zenon community.

More of my work related experience can be found here:

https://forum.zenon.org/t/around-the-table/349/4?u=cryptofish

**Goal:**

While the initial goal of this proposal will concentrate on implementing a version of the SDK for the standard Java compiler, extra attention will be made to make it compatible with Kotlin. A general Java coding style will be used and like the Zenon .NET SDK, closely stick with the SDKs provided by the Zenon Core Dev team.

@alien-valley.io valid point.

This page explains some of the key differences. Kotlin vs Java: the 12 differences you should know

Whether the Kotlin implementation will be completely compatible with x version of the standard Java compiler depends on the implementation and dependencies used.

The idea of this project is to create a Java implementation for the standard Java compiler version x and build from there. Although not necesarily required you could argue to first create a Java version and build direved versions from it for maximum exposure to the Java development community.

Of course there are more aspects to consider than only language differences. For example the debate between purism and pragmatism could favor one over the other.

What are the main advantages of a Java SDK?
I see some markets for

JS (frontend + node scripting)
Python (accesible scripting)
Kotlin / Swift (native Android & IOS integrations)
Dart (I guess? but exists anyway)

Btw, I have the same restraints on all the other languages as well.
I’ll fucking quit if someone does an OCaml/Haskel SDK for ZNN

CryptoFish · May 28, 2022, 9:38am

Other than its wide usage and adoption, I don’t think Java has any main advantages over the other languages. I believe the main purpose of creating various SDK’s was to make it as easy as possible for new developers to start developing on Zenon, in an language they’re most familiar with. As far as I understand that list of languages was decided upon in the Zenon SDK Status thread. So please don’t quit OCaml/Haskel is not on the list

You could argue why create an JS and Typescript SDK version if Kotlin is downgradable to both. Wouldn’t Kotlin be enough to serve 3 other SDKs?

If you want we could discuss this issue with a wider audience and let the community decide whether its worthwhile to continue?

The original list (below) was provided by MrKaine - I assume it’s their best guess of what the industry uses/wants?

@Sigli told us the devs are looking for these SDKs. We have 900,000 ZNN to accomplish these goals, plus the cross-chain solutions. Does Java / Kotlin mean Java AND Kotlin? The project was approved, so don’t we think it should move forward?

Updated the htlc branch with @georgezgeorgez latest htlc changes.

CryptoFish · April 22, 2023, 1:00pm

What?

Add support for the following Embedded Contracts

Spork Contract
Hashed Timelocked Contract

Why?

As of go-version v0.0.4 the Embedded Hashed Timelock Contract has been added and activated at Momentum Height 4188199.

The SDK needs to support the contracts to be able to interact with it.

How?

By implementing the contract RPC methods.

I think we should add them to the Dart SDK as well
