Never heard of them and the idea isn't and we've got other projects and coins that are already known mostly by the community. Well, if there is something different and unique with Walrus, the community will notice that. But until then, we won't be getting into those projects that despite they've got some good proposals, it's only a matter of time until we'd see if they actually deliver what they have said.
The space is full of projects making big promises, and most don’t live up to the hype. I hadn’t heard of Walrus either until recently, it’s definitely not mainstream yet. But what caught my eye was how they’re focusing on making storage usable in real time, not just for backups. Kinda different from the usual “store and forget” approach most storage projects take. Like you said though, all that matters is whether they can actually pull it off. Time will tell.
