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.

Hypergraph is a so-called “Layer 0” protocol designed to validate and store data from interoperable applications and networks—known as “meta graphs”—on its ledger. According to the announcement, its meta graphs can work with any data type, interface directly with external data sources, and accept mainstream programming languages such as Java.

“Constellation’s Hypergraph is the blockchain of blockchains,” Ben Jorgensen, CEO of Constellation Network, said in a statement. “The best way forward with Web3 and blockchain technology for all of us is interoperability and collaboration across chains and communities.”

In 2019, Constellation became among the first Web3 developers to clinch a contract with the US Department of Defense (DoD) to explore applications of blockchain technology for national security. Constellation is also partnered with the U.S. Space Force and Treasury Department, according to the statement.

According to its website, as part of its DoD contract, Constellation is investigating use cases such as facilitating secure encrypted communications and aggregating data from disparate legacy systems. It is also working with the US Air Force to prototype technology designed to secure military data streams from hostile cyberattacks.

Constellation's blockchain technology "would successfully thwart spoofing attacks from intercepting and replacing an existing data stream with a data stream from a hostile agent,” according to an Airforce memorandum cited on Constellation’s website.

Constellation distributed its native token, DAG, in 2018. The DAG token secures the Hypergraph network through a staking mechanism and is designed to benefit from the proliferation of new metagraph applications, according to the website.
