What are Oracles? #40
What are Oracles?  An oracle is a data feed or a search agent used by a smart contract to obtain information outside its native blockchain. Using a web API interface, it can communicate with news websites, traditional databases, other blockchains and their DApps, and much more. Without an oracle, a smart contract would only work for situations where all the needed information to be executed was found on the blockchain it resides on. For example, without an oracle, an Ethereum smart contract could not move funds based on the price of Bitcoin. If a smart contract wants to trigger conditions that exist outside their native blockchain, it needs an oracle to communicate with third parties on the internet to find what it needs. For instance, let’s say that there is a smart contract that says Joe will get 100 ETH if the Chicago Cubs win the World Series. Well, it needs some way to identify the Chicago Cubs, track baseball scores, and news. That’s where an oracle comes in. The oracle will track and deliver that information to the smart contract at the appropriate time the World Series is played. Allowing blockchains to communicate with the outside world and fetch the data they need is critical to their function. Imagine having an Excel spreadsheet, where you have the prices of the top 10 flavors of 2L bottles of soda. You want the real-time prices but you can’t be bothered to look online and enter in the price manually every day. If only you had a snippet of code to fetch it for you! That’s what an oracle does for a smart contract. Without them, a smart contract is just a bloated “if, then; else” statement.  There are different types of oracles that serve different purposes: Software Oracles - Software oracles look up information on websites. Examples of required data could be temperature, prices, and flight times. The software oracle extracts the information and sends it to the smart contract. Hardware Oracles - For smart contract conditions that needs data directly from the physical world, there are hardware oracles. For instance, when an employee enters the building, there is a movement and visual sensor to automatically clock them in and begin paying them for their time. These sensors then send the data to a smart contract, which triggers their pay at the end of the day. Inbound Oracles - A type of device or software oracle that provides the smart contract with data from the external world. For instance, when the price of Bitcoin hits $7,000, buy 3.5 BTC. Outbound Oracles - A type of device or software that gives smart contracts the ability to send data to the outside world, like a smart lock to the front door, that receives information on the blockchain that the owner has been verified through their mobile app and now the door needs to open. Consensus Based Oracles –When using only one source of information could be risky and unreliable, Consensus Based Oracles come into use. For further security, a combination of different oracles may be used, for example, 3 out of 5 oracles could determine the outcome of an event. An example is a prediction market bet on the outcome of an election.

ICO INSIGHT: MOVE OVER JARVIS. WISP IS HERE
NEOVATE For decades, our homes have remained more or less the same. Our phones have evolved from the size of bricks to small powerhouses full of advanced technology, yet our homes haven’t evolved much for over 50 years. We are stuck in the same home lifestyle as in the 60’s, turning the lights on and off with a flip of a mechanical switch, working a complex TV remote control, not knowing what half of the buttons do, while we ignore most of the oven’s features when we heat up dinner, and clean up mostly using outdated tools. The idea of advanced living has been floating around for quite some time. For years, Sci-Fi movies have depicted characters controlling everything in their environment with their natural voice and gestures, speaking to an intelligent computer entity that listens, understands, and can respond contextually. There is an AI assistant that does whatever the owner asks of it. But the current designs and developments have fallen far short of humanity’s aspirations. Where is this promised land? Integrated Living Wisp combines connected devices, artificial intelligence, and machine learning to create an ecosystem of "integrated living". It is connected with the home as well as with building facilities and a variety of the local service providers.   FEATURES: Adjust the lights and the temperature, control kitchen appliances, the TV and other entertainment systems; Contact the security desk, the property manager, parking and shuttle services of the building; Book a conference hall, reserve a table at the café, call a taxi or an Uber, order your favourite pizza, etc... Fully conversational AI Users can interact with Wisp using regular, conversational speech. It doesn’t require the user to memorize specific commands to understand what the user wants; it can understand natural human language and comprehend open-ended requests.

Blockchain and Real Estate #37
Blockchain and Real Estate Many people have bought a property at some point of their lives. They know how much headache it brings: They have to fill out copious amounts of paperwork and talk to a lot of people before receiving their keys and being able to move in. There are many people between the buyer and the seller, and they all want their share of the pie. These middlemen include: Appraisers Inspectors Seller’s real estate agents Seller’s real estate solicitors Buyer’s real estate agents Buyer’s real estate solicitors Insurance companies Escrow companies Mortgage Lenders And there may be even more! All of the fees for the above middlemen equate to anywhere between 5-10% of the largest purchase within a person’s life. This money is not going towards their new house. Without these payments to the businesses and agencies that manage pieces of information without which you can’t go forth with your purchase. Real estate transactions generated over $245 billion USD worth of revenue in 2017.

What is a Security Token? #34
What is a Security Token? Everything to Know About Security Tokens   The cryptocurrencies we are most used to dealing with are classified as utility tokens -- whether they’re for using a service, making a payment or offsetting a transaction fee on your favorite crypto exchange. However, in more recent months, we have seen a rise in popularity of what is known as the ‘security token’, or a token that derives its value from an external, tradable asset. A utility token, like Bitcoin and Ethereum, operates as a primary function of the network and often represent rights to network usage or opportunities to take advantage of the network by those who are holding these tokens. A security token, on the other hand, represents an electronically wrapped stake or share in a private interest or company -- and can extend to assets such as real estates, trusts, LLC, fine art, and so on. Often, security tokens give holders entitlement to a form of equity or ownership of a specific (fractional or whole) asset, as well as the expectation of profit through revenues, dividends or favorable price movements. In other words, security tokens are an investment contract similar to those of traditional financial instruments.

How Blockchain will change the Travel Industry #33
Blockchain and Travel Every one of us has travelled. Whether it is to a foreign country hundreds of miles away or just to another city within your country. We can travel by bus, rent a car and drive ourselves, or take the plane. If we don’t have any friends in the location we are traveling to, we can stay at a hotel, hostel, B&B or even couch surf. Travelling has never been as easy as it is right now. Platforms like Expedia, Skyscanner, and Booking.com have understood that people prefer secure platforms where they could see all of the options in one place and find the perfect solution for them without having to search through different websites for hours. These platforms make planning your travels convenient, but it comes at a cost. Often, these platforms take up to 20% of the ticket price that you pay. To change that, companies are looking to implement blockchain technology to the travel industry. This would give consumers the possibility to book hotels, plane tickets or anything else using smart contracts, therefore eliminating the middlemen. This week we cover how blockchain can change the Travel industry including: Online booking Travel industry security Luggage tracking Loyalty management   ____________________________________________ Listen to Crypto and Blockchain Talk for more interesting topics! If you like this episode, give us 5 stars in iTunes or Stitcher, Thank you for listening!   Crypto and Blockchain Talk - Making You Smarter   SUBSCRIBE to our channels and never miss an episode: SPOTIFY iTunes Stitcher Soundcloud Google Play Music Tunein Castbox Pocket Casts Overcast iHeartRadioPlayerFM Twitter YouTube LinkedIn
