In the new Web 3.0 paradigm, we have decentralized data storage (IPFS) and decentralised business logic (smart contracts), but are missing a database protocol. Building this missing critical part of the infrastructure is a requirement before we can see mass adoption.

At the moment, app developers cannot create great UX due to lack of structured data; blockchains don’t scale to enterprise ‘database’ amounts of data, and customer blockchain databases are built from scratch and without open protocols which has the risk that it will lead to replacing the old data silos, with new ones.



Haja Networks is an ambitious team comprised of some of the early team behind OrbitDB and IPFS that is building two new and complementary open-source protocols to enable decentralised databases to interoperate.

  • Decentralised Database Protocol: An open protocol to build decentralised databases that enables users to own and control their data. The protocol integrates with existing databases, unlocking them to the decentralised web, and enables interoperability between structured data sources.
  • Decentralised Database Network: A marketplace for decentralised database services allowing providers to monetize their software whilst data hungry businesses have straightforward access to the widest range of services.

Both of these open-source products would enable interoperability between different blockchains and allow users to sell or lease their data to businesses while maintaining control over what information is accessible to third-parties



Haja Networks is led by CEO and pioneering developer Samuli Pöyhtäri (@haadcode) and Chief Technology Officer, Vesa-Ville Piiroinen. Piiroinen has decades of experience in distributed systems and enterprise database and security solutions. Pöyhtäri is a former IPFS core developer, and is at the forefront of decentralised databases and storage systems. He is also well known for creating OrbitDB a peer-to-peer database for the decentralised web that is used by various decentralized applications and projects.

Haja Networks have already firmly established themselves as a critical component to useable decentralised databases partnering with Berlin based BigchainDB who have now also made a strategic investment.
