Cosmos Whitepaper Introduction
The combined success of the open-source ecosystem, decentralized file-sharing, and public cryptocurrencies has inspired an understanding that decentralized internet protocols can be used to radically improve socio-economic infrastructure. We have seen specialized blockchain applications like Bitcoin (a cryptocurrency), Zerocash (a cryptocurrency for privacy), and generalized smart contract platforms such as Ethereum, with countless distributed applications for the Ethereum Virtual Machine (EVM) such as Augur (a prediction market) and TheDAO (an investment club).

To date, however, these blockchains have suffered from a number of drawbacks, including their gross energy inefficiency, poor or limited performance, and immature governance mechanisms. Proposals to scale Bitcoin’s transaction throughput, such as Segregated-Witness and BitcoinNG, are vertical scaling solutions that remain limited by the capacity of a single physical machine, in order to ensure the property of complete auditability. The Lightning Network can help scale Bitcoin transaction volume by leaving some transactions off the ledger completely, and is well suited for micropayments and privacy-preserving payment rails, but may not be suitable for more generalized scaling needs.

An ideal solution is one that allows multiple parallel blockchains to interoperate while retaining their security properties. This has proven difficult, if not impossible, with proof-of-work. Merged mining, for instance, allows the work done to secure a parent chain to be reused on a child chain, but transactions must still be validated, in order, by each node, and a merge-mined blockchain is vulnerable to attack if a majority of the hashing power on the parent is not actively merge-mining the child. An academic review of alternative blockchain network architectures is provided for additional context, and we provide summaries of other proposals and their drawbacks in Related Work.

Here we present Cosmos, a novel blockchain network architecture that addresses all of these problems. Cosmos is a network of many independent blockchains, called zones. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountability guarantees hold over the behaviour of malicious actors. Tendermint Core’s BFT consensus algorithm is well suited for scaling public proof-of-stake blockchains.

The first zone on Cosmos is called the Cosmos Hub. The Cosmos Hub is a multi-asset proof-of-stake cryptocurrency with a simple governance mechanism which enables the network to adapt and upgrade. In addition, the Cosmos Hub can be extended by connecting other zones.

The hub and zones of the Cosmos network communicate with each other via an inter-blockchain communication (IBC) protocol, a kind of virtual UDP or TCP for blockchains. Tokens can be transferred from one zone to another securely and quickly without the need for exchange liquidity between zones. Instead, all inter-zone token transfers go through the Cosmos Hub, which keeps track of the total amount of tokens held by each zone. The hub isolates each zone from the failure of other zones. Because anyone can connect a new zone to the Cosmos Hub, zones allow for future-compatibility with new blockchain innovations.

The technology of blockchain is one of the most promising that exist today, ranging from smart contracts to the creation and commercialization of cryptocurrencies.

In the last few years, this market has been expanding in a surprising way, solving several problems with its decentralization and speed. Today, it is possible to make several records, payments, and even raise funds for companies by using this technology.

The cryptocurrency market has already surpassed the value of renowned companies such as Facebook and Amazon. Cryptocurrencies are not only only a solution for depreciating currencies, such as USD, but also for our daily life. For being decentralized, safe, fast and low (or no) cost in transactions, these currencies exceeded the value of US $600 billion at the end of 2017.

Although this market is in constant and wide expansion, most cryptocurrencies have a complicated process of acquisition and negotiation. The wallets offered today are often poor in terms of usability, and they offer few resources.

With all these obstacles, the experience for new users becomes diffi cult and creates unnecessary uncertainty. Many users end up in fear and avoid this market as a whole due to the risk of being scammed. The Lunes Platform is a solution to the complications.

Lunes has the resources for anybody interested in the crypto world, ranging from beginners to advanced users. Its design was created to facilitate and offer practicality, simplicity and intelligence.

Jewel was made to dispense the limit between the exemplary trading market and the Digital currency market. In view of three stages, Jewel enables you to play out a wide range of budgetary exchanges with both fiat cash and digital money. A change from fiat cash to crypto coins and the other way around still introduces a specific trouble and this way the customary market with an everyday turnover of 5 trillion US dollars and a multi-billion crypto advertise are as yet isolated from one another. In such a manner, troubles are made for fiat holders and other advanced resources.
Our undertaking enables our financial specialists to deal with their funds on the same stage, which spares them from such issues. Beneath we portray in more detail the items, our vision of the task, a few subtleties and approaches to actualize.

In the present market diamonds are an unpredictable resource since they are not compatible, so there is a major hole between worldwide money related markets and the diamonds eco system. Dissimilar to different valuable resources, it is hard to have a solitary advanced trademark, on the grounds that most of the assertions in the diamonds eco system are private understandings. Diamonds are themselves not equivalent to one another in many qualities and the very idea of liquidity is hard to credit to these diamonds. Furthermore, diamond exchanging from the earlier happens utilizing fiat cash. For dealers these tasks are inaccessible and, in this manner, there is no comparing on the web stage for making such exchanges.
Underneath we depict in detail our vision of how to beat a change from the present circumstance in the diamond market to a future model of web based exchanging with such a novel budgetary resource like Jewels.

On account of the Diamond Computerized Testament innovation, our Jedex stage will eliminate the compatibility issue and accomplish full straightforwardness of the market estimation of jewels. What more, we will likewise give a Blockchain stage to jewel exchanging.

The articulations of buyer interest for jewels have started to move lately. At first, diamonds were utilized just as Jewels, however at this point jewels have turned out to be significantly more frequently viewed as ventures and now the interest for diamonds as speculations has risen to 5%. By 2015, the all-out estimation of the diamonds biological community showcase was at that point 79 billion US Dollars. Till the present time diamonds stay only an elective sort of venture. There are three primary factors that limit diamond exchanging.

1) Absence of a solitary cost since none of the diamonds can be considered tradable because of the way there is an endless amount of attributes for every individual jewel.
2) Absence of straightforward costs and certain gauges in the diamond eco system.
3) Absence of liquidity, which makes it practically difficult to move jewels at a genuine market cost.

So as to the item can get a Diamonds Digital Certificate, it is important to consider two viewpoints:
The change of a Diamond from a one of a kind advantage for a benefit that has a definite showcase esteem, and the making of an exchanging stage that will permit the exchange turnover with diamonds.

Therefore, our venture faces a few inquiries:
– How to guarantee the straightforwardness of the estimation of jewels available?
– How to compose reciprocal jewel exchange turnover?
– How to guarantee the rule of compatibility of jewels?

The Growing Problem of Spam Calls:
Over 147 million mobile happen in United States per day. It is estimated that among this huge number of calls, 82 million are spam calls. This number is expected to reach 100 million by the end of 2019.

Several solutions have been designed to curb this menace in the communications industry but have been ineffective or failed entirely, either due to legal problems, hackability and caller ID spoofing, especially when it comes to previously proposed solutions such as Whitelisting/Blacklisting, Captcha and Crowdsourcing. An advanced method proposed to resolve this endemic challenge is to use intelligent real-time analysis techniques coupled with trusted big data to detect and apprehend these spam calls despite their complex change of identities.

How Does Robocalls 2.0 Work:
By coupling the capabilities of artificial intelligence (AI) and blockchain technology, Robocalls 2.0 will use its unique AI algorithm to scan through its user established and blockchain secured spam call ID database, to predict unwanted calls based on inbound dialing patterns. The structure relies on the Ethereum blockchain to validate, notify, and block this activity. Leveraging this powerful technology, our algorithm will create the biggest predicted black list database of unwanted and scam numbers in the blockchain.
