Frankly speaking, I cannot say it is necessety. We were trying to find a way to utilize the technology for the hacathon so that it will bring value.

And yes, it did consume a lot of time. First we wanted to use ZoKrates to generate Rust code for Fluence. However, we found out that it does not generate Rust source code - only bytecode. So, we had to write the code ourselves, which was pretty complecated since none of us knew Rust) A mentor from Fluence team helped us a lot. Also, we contunued working on that part after the hackathon, too.
