# RISC-V support
Status: runs a generic slow implementation
>
>
> Please add support for an efficient implementation on RISC-V :D
>
> I have been lea…rning about the crypto and vector RISC-V extensions and they look very nice.

> I found this implementation:

> Can it be used here?
>
> I don't think there's a board available with these extensions yet. For now I can test and benchmark in qemu and FPGA.
>
> What this brings now, in my opinion, is a path towards decentralization in which local collectives, geographically grounded, can become the resilient foundation for the network with very efficient and transparent machines. We can start designing those machines.
