On July 15, Constellation Network opened its Hypergraph blockchain, created in partnership with the United States military, to application developers at a global hackathon event hosted alongside technology giants IBM and Panasonic.The hackathon marks the debut of Constellation’s “meta graph” application layer, which enables third-party developers to build Web3 applications—or even new layer-1 blockchains—on top of Hypergraph’s existing network.
