Use cases

  • Neutrino payments: case study – zero-fee off-chain transactions.

    Suggests the smart contract usage workflow (and explains in great detail the structure of underlying smart contracts) of creating the process of off-chain payments, where a lot of micropayments may be securely transferred between parties, requiring only the initial and the final transaction to be registered in Universa Blockchain.

    May be used as a good (and well-detailed) example how the advanced logic may be implemented using the features of the smart contracts; as well as example of smart contract structure and concepts.
