I think this proposal is a good answer to making sure that projects that do well in hackathons turn out to be useful things in Arbitrum. This setup of splitting the program into a validation phase and a development phase improves the success probability of each project. Only those projects that show real needs will receive further funding and capacity. The way they designed it helps fund use to be more efficient for long-term sustainability. Also, the partnership between RnDAO and Arbitrum helps in more cooperation as well as sustainability on the platform, which helps participants not just with money but with mentors, resources, and networks.
