hey all!
just as a (big) study exercise, I want to rewrite a cryptocurrency core in Kotlin, it's usually written in C++ or Rust.
what should be the most efficient way to run it?
Graalvm native? adoptjdk jvm (properly configured)? Kotlin Native? (only *unix support is enough)
I don't expected to have the same "performance", but just want to discovery how to be the closest possible to the original project.
Does anyone here has experience on cryptocurrencies core development?

Hello @Luiz Aguiar. Please can you provide a link to the core library?

The original in C++: https://github.com/nanocurrency/nano-node
A rewrite in Rust: https://github.com/feeless/feeless

I dont think I know enough to really give advice or opinion on what route you should take.

About the different Kotlin versions:
• Kotlin/JVM is optimized for throughput. It's a bit slow to startup, and it eats some RAM, but it's crazy fast when it's going. Best for servers/software that runs for a long time.
• GraalVM Native is optimized to startup fast and have low latency. Best for command-line apps, stuff that needs to be started and stopped all the time.
• Kotlin Native is optimized for low memory usage. Best for IoT, phones...

I'm no where near an expert, it's just what I understand (so take with a grain of salt)

@Luiz Aguiar, I think you can look at the comparisons b/w the different options listed by @CLOVIS above and make a decision, based on what you consider as more important.

Thanks for the comments guys… I gonna do a bit more research on this topic, but I think I have some insights already.
Any additional hint will be very appreciated.
