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.
Ultra is a protocol and platform positioned to disrupt the $140bn USD gaming industry using blockchain technology to allow anyone to build and operate their own game distribution platform or virtual goods trading service. In doing so, it challenges the current monopoly held by industry heavyweights Steam, Google, and Apple. This will unlock new opportunities and create value for all the actors involved. Large commercial partnerships are signed, the protocol and platform have been built and will be launched in open beta in October 2019. UOS is the Token that powers the Ultra Ecosystem and can be used to purchase everything on the platform, including games, virtual items and ads for game developers. Ultra will accept traditional forms of payment such as Paypal and credit cards as well. These fiat currency transactions are converted to UOS seamlessly on the backend and are completed on the blockchain with UOS tokens. The token will also be used across the platform in many non-transactional ways including betting, tournaments, and donations. TIMELOCK: 10 to 20% of every transaction will be kept in a smart contract for 60 days. In addition, 5% of Ultra profits will be reserved for 2 years to fund exclusive games that use its blockchain and NFTs capabilities. ENGAGEMENT: Tokens are earned by performing specific actions such as; helping developers to build better games; watching ads; beta testing; answering surveys, and more. STACKING: Players can get rewarded with free games, swag and exclusive content just by holding tokens. SPENDABILITY: Users can buy and sell games/items for UOS, and in hundreds of shops through partners.
