VITE - A Next Generation High-performance Decentralized Application Platform DAG Ledger Transactions in Vite are grouped by accounts. That is, each transaction only changes the state of one single account. Send transactions are separated from receive transactions, thereby obviating the need to wait for a transfer to be complete before the initiation of another transaction. The hierarchical design of the consensus algorithm allows horizontal scalability in consensus groups. Asynchronous Architecture Vite splits transactions into transaction pairs according to a 'request-response' pattern. The writing and verification of transactions are asynchronously decoupled, thereby supporting ultra-high throughput. Inter-contract communications are based on an asynchronous messaging model. Reactive Contract Message-Driven With an event-driven architecture, every smart contract is viewed as an independent service. Contracts communicate via messages without sharing state. Solidity++ Solidity++’s syntax is compatible with most of that of Solidity. The new syntax supports asynchronous semantics, contract scheduling, and provides a series of standard libraries, such as string manipulation, floating-point operations, basic mathematical operations, containers, sorting, and so on. Integrated Decentralized Ecosystem End-to-end system for value transfer Vite itself is a decentralized exchange that supports digital asset issuance, cross-chain value transmission, and inter-token transactions based on the Loopring protocol. A quota-based resource allocation mechanism allows light users to pay zero fees and gas. Users can obtain computing resources in multiple ways. Vite also supports quota leasing. dApp Mini Programs The Vite client features an engine for creating HTML5-based decentralized mini programs. This engine simplifies the process of dApp development and deployment.
Spendcoin is a decentralized cryptocurrency that powers the Spend.com ecosystem of products. Spend has two financial services products, the Spend App and Spend Card, which are products of Spend.com that give our users a multi-currency digital wallet that they are able to store fiat and digital assets/currencies. They will be able to buy, sell, store, manage, and exchange all supported currencies within the app. The Spend App is available on iOS, Android, or Web based devices. The Spend prepaid debit card allows users to send fiat based currencies loaded onto it via the Spend App anywhere that accepts MasterCard. Spend Foundation is also launching a decentralized educational platform called Blockchain University (bu.org). Blockchain University is designed to run off our open-source blockchain called Cross Ledger which incorporates a hybrid delegated proof-of-stake consensus model called Proof-of-Support. Proof-of-Support creates a learning based ecosystem that rewards those users who support and answer the knowledge base and Quora style system. Spendcoin will be the native digital currency powering the platform. Blockchain University and Cross Ledger are planned to launch in 2019.
