Hi,

Following up to conversations about [Web Assembly](https://webassembly.org/) and its support by [Harmony](https://medium.com/harmony-one/harmony-2019-roadmap-497d7ed0a98b).  
This is a generic topic about Harmony’s vision for WASM and specifically whether there is perceived advantages of writing Web Assembly in a specific language? (i.e. rust of go vs solidity)

Cheers,

John

Hey @john,

Really glad you’re opening up this topic. I am not sure about the advantages of writing WA in Rust or Go versus Solidity. We need some language and compiler guys in here! I’m looking at you @stse!

My best guess is that you would need to write in a functional programming language for formal verification. So Rust would be better for contracts. But I think Go’s primary advantages are in distributed systems which wouldn’t be relevant for smart contract contexts, so I don’t think one would choose to use Go for if you’re writing for WASM smart contracts.

The choice of the language depends on the end application I guess. What are your thoughts?
