RandomX

RandomX is a proof-of-work (PoW) algorithm that is optimized for general-purpose CPUs. RandomX uses random code execution (hence the name) together with several memory-hard techniques to minimize the efficiency advantage of specialized hardware.

RandomX

Xdagj

The java version of xdag

xdagj-native-randomx's Issues

SIGILL during JNI call

hi @Holt666 , @cherry1603 , I am running into issue while running Example.java
Tried both to build project , and importing xdagj-native-randomx-0.1.7 as Maven dependency into another project, same issue
