Only project I know about is Siacoin which has already been suggested by another user. It's a good project per se but the project has not received many attention ms lately. I've known the project for like 3 years and haven't heard anything go wrong with the project yet except that no hype around the project. If you want to use it for development purposes, you can try out the project and see.
I've heard that as well and if it is still alive today, then, I guess, they are doing something right. Just head to their site -
https://sia.tech/ and look if it will fit with OP's needs. They are top 107 right now, so better than most alts out there. They are also present in Binance, which translates that sia surpassed the strict requirements of binance.
