    • QUOTE: ... The original vision for Bitcoin was to build precisely such a payment system. In many ways, it was successful; Bitcoin has achieved high levels of decentralization compared to centralized money supplies, and remarkable levels of awareness for cryptocurrencies, although merchant adoption has been nearly non-existent. ...

      ... Unit-e is a cryptocurrency that specializes exclusively on payments, with a strong emphasis on performance and state-of-the-art, decentralized scalability. Whereas blockchains offering smart contracts must solve the problem of full, decentralized state-machine replication, lightweight payment transactions offer massive parallelism. Consequently, we narrow the objectives of a general purpose blockchain system, and tackle these questions in a holistic, first-principles manner. We note that although focused on payments, we find that much of the research output involved in the design of Unit-e also provides programmability (e.g. through smart contracts written in Turing or pseudo- Turing complete languages); we discuss these ramifications in the appropriate sections throughput the manifesto. To become a ubiquitous global payment system, United is designed to meet the following five requirements in a fully-decentralized manner:

      1. . Security. The system should prevent unauthorized or invalid payments from being executed.
      2. . Latency. Transactions should be processed seamlessly, on the timescale of seconds.
      3. . Throughput. The network as a whole should be able to confirm up to thousands of transactions per second.
      4. . Usability. The system should be accessible at all times, offer low and predictable fees and a low cost of operating the network and provide a seamless and predictable user experience.
      5. . Privacy. The system should prevent unauthorized parties from accessing transaction logs.
