How GraalVM can be used?

After many years of research and development GraalVM project has matured enough end became production ready.

From Ergo perspective GraalVM platform opens many unique opportunities in the nearest and the distant future. Here is a summary of some GraalVM related facts:

  • Ergo node can run on GraalVM without any modifications, in fact GraalVM is fully compliant with JDK 1.8 (which is minimal requirement for Ergo Protocol Client)

  • Graal's native-image tool can be used to compile JVM applications into native applications which can run without JVM. It can also produce shared libraries (*.so files on Linux and *.dylib files on MacOS) that can be used from C/C++ applications (and also from JavaScript, Python, etc using FFI).

  • All cryptography classes BouncyCastle Java library which are used in Ergo reference implementation can be compiled to shared library and used from non-JVM languages.

  • All the code from ErgoScript interpreter, ergo-wallet and this Appkit library is compatible with native-image and can be compiled into either native application or shared library.

  • Appkit API interfaces can be used from JavaScript and Python by design. They can also be used from C/C++ .

  • Appkit can be pre-compiled to native-image based launchers of both JavaScript and Python to enjoy fast startup and lower runtime memory overhead when running scripts

  • Appkit native shared library can be used from Python and JavaScript through FFI
