  • To have a very thorough understanding of how Swarm behaves, while simultaneously elevating everybody else’s understanding
  • To help the research team’s ideation process by running custom experiments with the Bee node in Swarm clusters
  • To increase the quality of the research team’s proposals by backing them up with data
  • To shorten the idea-validation cycle by creating proof-of-concepts
