I am not being able to figure out, which lang is best for creating a private blockchain?

  • What do you want to do with your private blockchain? You can always create a new Ethereum blockchain without coding a single line. Commented Feb 22, 2018 at 15:19
  • This is off-topic any language should be good enough if you are a capable programmer. Bitcoin, Litecoin, Dogecoin are written in C++ (there are other implementations in Rust y Java), Ethereum has implementation in Go, Rust, Java and C++. Other blockchains has implementations in Javascript, Python, Scala.
