Smart contracts on Ethereum are fully self contained and any information or access to off-chain data is restricted. Tellor solves this problem by creating a system where parties can request the value of an off-chain data point (e.g. ETH/USD) and miners compete to add this value to an on-chain data bank, accessible by all Ethereum smart contracts. Inputs to a data series are secured by a network of staked miners. The main Tellor smart contract creates a time series of each requested data series and aims to become the standard source of high value data for decentralized applications. This oracle, “Tellor”, utilizes similar incentive mechanisms to other cryptocurrency systems through the issuance of Tellor’s token, Tributes, that are used to request a particular data series from miners.
MomoCash is an innovative cryptocurrency. A form of digital currency secured by cryptography and issued through a decentralized and advanced mining market. Based on Dash, it's an enhanced version, featuring the masternode technology with 50% Reward, near-instant and secure payments as well as anonymous transactions. Momo is an experimental new digital currency that enables anonymous, instant payments to anyone, anywhere in the world. Momo uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. MomoCash Core is the name of the open source software which enables the use of this currency. The emergence of blockchain-based decentralized digital currencies woke up hopes for the beginning of a better world. A world, where wealth is distributed fairly without control and influence of a powerful middleman. Although blockchain technology equipped us with a perfect tool to make this dream come true, it will not happen by itself. The concept of a socially responsible cryptocurrency inspired us to create Ultima - a platform designed to support endeavors of its community in various areas. The Ultima Multi-Module Platform (MMP) includes functionalities ranging from a digital marketplace to crowdfunding and charity components. By working together on noble causes we will regain the faith in cryptocurrencies.
