Cardinal Cryptography


We are a software house specialized in blockchain and distributed applications. We invent, research, develop, advise, and support. As experts in both the technical and business side of distributed ledger technologies, we take away the excuses for not using it. We’ve built Aleph Zero and brought it to the market. It’s a state-of-the-art, peer-reviewed consensus protocol that we use to deploy custom blockchain solutions. However, we don’t limit ourselves to this technology only. If you prefer, we can work with Ethereum, Corda, or Hyperledger. We want to fit the technology towards your specific needs and industry.
