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.
Quantstamp is a security-auditing protocol for smart contracts. As a apps platform, Ethereum has proven its security time and again. However, apps and smart contracts on top of Ethereum may still have bugs in which malicious players can cause havoc on the network. The two most notable examples of these being the $55 million DAO hack and the $30 million Parity wallet bug. These issues not only affect the people who’ve had their funds stolen, but they also diminish the credibility of the entire ecosystem. Quantstamp is making smart contracts more secure through automated software testing and a system of bug bounties. Although starting with Ethereum, the team is building the protocol to be available on any DApp platform in the long run.In an industry where security is a primary concern and bugs have caused the theft of millions of dollars, Quantstamp should help to legitimize blockchain projects and ensure that large-scale smart contract hacks are a thing of the past. Quantstamp held a successful ICO in November 2017 in which the team raised a little over $30 million dollars. They distributed 650 million (65%) QSP out of the 1 billion total supply to ICO participants at a price of $0.072 per token. After the usual post-ICO volatility, the QSP price stabilized at around $0.10 (~0.000005 BTC) through the end of November. The price followed the trend of the altcoin market and rose rapidly to an all-time high of $0.82 (~0.000051 BTC) before slowly falling to its current price of ~$0.286. The QSP price weathered the beginning of the year market downfall better than most other altcoins.
