holochain
i see the project as a herculean attempt at rewriting the foundations of our personal computing stack as distributed, privacy and open-source - enable our social coordination systems to be radically more conscious, resilient and regenerative.
there's an extremely high barrier for entry though for non-developers at the moment (and developers alike, considering the amount of inner work necessary to recognize its value).
