Hello, sorry to bump this older thread but was curious if anybody had an opinion now in 2018 on which languages would be most helpful for bitcoin/blockchain projects?

C++ is what bitcoin is written in

Go is mature port for Ethereum but the bug with the Parity wallet in Solidity?

Many local coding schools are pitching Python as good language and since I also have an interest in data science/GIS, this would be nice since I'd be knocking out 3 birds with one stone but I also like Clojure based on the designer of the language, Rich Hickey.  Love his talks on Youtube.

Haven't found much on Scala but since Spark is built with Scala, was hoping to somehow work on how blockchain and Big Data might compliment each other?

I know Tezos was built on Ocaml but if I'm going to learn a language that has both functional and OO elements, then I'd prefer to stick with Clojure.

Lastly, not sure if how concurrency/parallelism directly impacts blockchain but if it does, why aren't more projects built using Elixir/Erlang?

Any thoughts greatly appreciated!

thanks in advance,
Z
