Implementing Driving Records Blockchain In Ios Usingswift

iOS Developer, speaker and educator. Author of ARKit for iOS Developers and Mastering ARKit for iOS Udemy course. Lead instructor at DigitalCrafts. Implementing Driving Records Blockchain in iOS UsingSwift Whether you like it or not car insurance companies access your driving records in order to provide you with the updated insurance rates. If you are moving from one state to other your driving records may follow depending on the rules and regulations of the new state. Usually, the driving records are stored in old government systems which are vulnerable and open for cyber attacks. In this post I will implement a Blockchain in iOS using Swift language, which will be responsible for storing the driving records of users. Next, I will expose the Blockchain as a Web API using Vapor, server side Swift framework. Finally, I will create a simple interface which will communicate with the API to fetch and display driving history of a particular user by their driving license number. The complete code can be downloaded here . I also provide training workshops on ARKit, iOS, React and Redux development. If you or your company is interested in the workshops then please feel free to contact me. Lets start by implementing the domain models used in the application. In order to implement a Blockchain we will need the following models: Blockchain and Block are self explanatory. The Transaction model represents the Driving Record of a user. If you dont like the name Transaction then you can change it to DrivingRecord. In this post I will be using Transaction, which will represent the driving record of a user. The Transaction class consists of properties related to driving record. This includes the following: Obiviously, you can add more properties to store more information related to the Continue reading >>

How To Design A Blockchain Network In Swift /january 23, 2018 By Wayne Bishop

Bitcoin . The name invokes reactions of interest, speculation and curiosity . As someone interested in iOS development and computer science, it has been hard to resist exploring the technology and how it works. It is fascinating that even though crypto-currencies like Bitcoin are seen as new solutions, their design is based on a few concepts based in computer science. For this introductory article on Bitcoin, we'll review its core technology - known as a Blockchain, in Swift. These days, the idea of sending or receiving money online is anything but new. On the contrary, much of the world economy is now conducted through the Internet, with some countries openly discussing the elimination of paper currencies altogether. Even though consumers, banks and institutions have designed a system that works, opportunities still exist for improvement. To see how ideas like Bitcoin differ from traditional banking consider the following: In traditional commerce, Banks act as the coordinator and trusted authority for financial transactions. As a result, if person A wants to send or receive funds with person B, the exchange must be authorized by the Bank before any action takes place. Assuming the exchange is authorized, the Bank will facilitate the exchange and record the transaction in its books - otherwise called a private ledger. One reason for the Bank's success is accountability. Meaning, if any dispute over a transaction occurs, either person A or B can contact the Bank for more information. Another item to note is privacy. Even though persons A and B conduct business with the same Bank, neither party are permitted to view any transactions beyond their own. Crypto-currencies like Bitcoin operate differently. Their model is based on popular Internet-based strategies like wisdom Continue reading >>

What Apple Can Teach Blockchain App Designers For 2017

What Apple Can Teach Blockchain App Designers For 2017

What Apple Can Teach Blockchain App Designers for 2017 Steve Ehrlich, Ron Quaranta and Matthias Roebel Jan 8, 2017 at 16:30 UTC|UpdatedJan 9, 2017 at 03:42 UTC Steve Ehrlich is an associate and lead analyst at Spitzberg Partners, a boutique corporate advisorythat has strategic relationships with firms including Ming Labs and the Wall Street Blockchain Alliance. Matthias Roebel is CEO of Ming Labs, and Ron Quaranta is chairman of the Wall Street Blockchain Alliance. In this CoinDesk 2016 in Review special feature, Ehrlich, Quaranta and Roebel argue that a focus on user experience can help blockchain firms better communicate to the mass market in 2017 and beyond. Most people hear the word blockchain and immediately concede that they may never take advantage of this innovative technology because they cannot "use encryption" or code. As those of us in the blockchain sector look to 2017 as the year where we begin to move beyond a purgatory of proof-of-concepts and pilots into full product integration, it is crucial to enable would-be users to clear this important mental hurdle. Fortunately, this is not a new problem for the technology industry. Ask random people on the street to explain how the Simple Mail Transport Protocol ( SMTP ) works and you will likely get a blank stare. All that they know is that once they press send, their email gets to its desired recipient within seconds. What is the significance? It means that users need to stop focusing on how blockchain works and instead focus on its future applications. In order to get to this point, blockchain applications need to be intuitive to the everyday user, which all comes down to a simple and elegant user experience (UX). Many of us know people who were nervous about basic feature phones, let alone smartphones. How Continue reading >>

From The Doctor To The Dmv, Blockchain Can Make Governments Swift And Secure

From The Doctor To The Dmv, Blockchain Can Make Governments Swift And Secure

From the doctor to the DMV, blockchain can make governments swift and secure Posted on April 16, 2018 - 3:00AM 4.16.18 - 3:00AM Estonia is the first country to offer e-Residency, a government-issued digital ID available to anyone in the world e-Residency Although most commonly associated with cryptocurrencies like Bitcoin, blockchain technology is also being used all over the world for many intriguing purposes. One of the most impactful could be the way in which governments themselves are using it to ensure that the data of citizens and political figures are protected, from both other nation states and themselves. In some cases, thats already been realized. From protecting the integrity of citizenship data on government databases, to proving that your next second-hand car wont kill you, blockchain has the potential to enable trust in data like never before even if you dont trust the government behind it. Estonia is leading the way, but not as much as some think People always come here and say, oh, Estonia, it is the country of the blockchain. This is some sort of misunderstanding, Federico Plantera, of the E-Estonia Showroom , told Digital Trends in an interview. Although Estonia has leveraged its Keyless Signature Infrastructure (KSI) system since 2012, there is some debate over whether it can be described as a blockchain. This article is part of our series Blockchain beyond Bitcoin . Bitcoin is the beginning, but its far from the end. To help you wrap your head around why, were taking a deep dive into the world of blockchain. In this series, well go beyond cryptocurrency and hone in on blockchain applications that could reshape medical records, voting machines, video games, and more. As Plantera described it to us, KSI is its own variant of blockchain . It grows on a Continue reading >>

Ark-swift Interface For Easy Ios Integration With The Ark Blockchain

Ark-swift Interface For Easy Ios Integration With The Ark Blockchain

ARK-SWIFT Interface For Easy iOS Integration With The ARK Blockchain We are very proud to announce ARK-SWIFT integration for ARK, thanks to one of our community developers. Community developer SleepDeficit has been working very hard to contribute to the ARK Ecosystem. He is continuing development on some ARK IoT projects. In the mean time has brought us SWIFT integration for ARK, completely written in SWIFT 4.0. SWIFT GITHUB: Swift is a powerful and intuitive programming language for macOS, iOS, watchOS and tvOS. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design, yet also produces software that runs lightning-fast. Swift 4 was developed in the open at Swift.org, with source code, a bug tracker, mailing lists, and regular development builds available for everyone. This broad community of developers, both inside of Apple, as well as hundreds of outside contributors, work together to make Swift even more amazing. Swift already supports all Apple platforms as well as Linux, with community members actively working to port to even more platforms. Swift includes features that make code easier to read and write, while giving the developer the control needed in a true systems programming language. Swift supports inferred types to make code cleaner and less prone to mistakes, and modules eliminate headers and provide namespaces. Memory is managed automatically, and you dont even need to type semicolons. Swift also borrows from other languages, for instance named parameters brought forward from Objective-C are expressed in a clean syntax that makes APIs in Swift easy to read and maintain. The features of Swift are designed to work together to create a language that is p Continue reading >>

Blockchain Programming Inios

Blockchain Programming Inios

UPDATE: I am proud to announce that my new course Blockchain Programming in iOS Using Swift is now available. Enroll now for only $10.99. Blockchain is the technology behind popular cryptocurrencies including Bitcoin. The main concept behind Blockchain is to provide a distributed ledger which is not controlled by one central party. In this post I will show you how you can use iOS/MacOS to create a very basic Blockchain in Swift language. NOTE: This post does not cover nodes/peers, validation, rewards etc. The quickest and the easiest way to to get started is by using Swift Playgrounds. For this particular demo, I used macOS Playgrounds since it has some useful functions for generate SHA hash. The first step is to implement the Block class which will represent a single block in a.. blockchain. The implementation is shown below: The details of the Block class is shown below: index The position of block in the blockchain. Index of 0 means that the block is the first block in the blockchain. Index of 1 means it is the second block in the blockchain.. you get the idea right! dateCreated The date when the block was created previousHash The hash value of the previous block nonce Auto incremented number which plays an important role for mining the hash data Any valuable asset. This can be money, medical information, real estate information etc key This is a computed property which is passed to the hashed function The Blockchain class requires an instance of a block to initialize itself. This block is also known as genesis block, since it is the first block in the block chain. The implementation of Blockchain class is shown below: The addBlock function adds the block to the blockchain. The next block is based on the previous blocks hash, which is one of the properties used by t Continue reading >>

Ethereum On A Iphone Decentralize Today

Ethereum On A Iphone Decentralize Today

Getting started with Ethereum apps on iOS There is no installation package, build by the Ethereum community, ready for the iOS. But in a way it is possible to build something. Let us start with the Ethereum client architecture to see what we have. Ethereum is an example of a very fast growing blockchain implementation. Actually, Ethereum has surpassed Bitcoin in amount of nodes in the public network, at this writing moment, see the current number of nodes . Ethereum is a cryptocurrency. Ether is the currency. Ethereum was created as a clone of the Bitcoin core, having its own blockchain network - a public, distributed ledger. The Ethereum network is called P2P Wire Protocol Network. The most exceptional: Ethereum has a whole programing platform on top of its cryptocurrency, implemented in every client. The programs are called DApps, Decentralized Applications. People are doing things in Ethereum that are not possible right now in Bitcoin. It has created a new generation of developers which never worked with Bitcoin but are interested in Ethereum. See story from Coinbase . What is very real, though, is the possibility that Ethereum blows past Bitcoin entirely. See r3cev.com/blog/2016/5/29 Every node in the network is called a Ethereum Client and it has nothing to do with a client-server architecture. There are only clients nodes in the Ethereum network. Where the Bitcoin blockchain distinguish between a full-node, having a full copy of all transactions, and a lightweight node, having only what is needed for a wallet, the Ethereum has only full-nodes. But there is being working on a lightweight node, see what-should-i-install-on-a-mobile-tablet . Meaning, we must wait on the official Light Client for the mobile devices. While we are waiting on a lightweight solution for Continue reading >>

Google's Angular, Apple's Swift: Meet The Decade's Fastest-growing Developer Tech

Google's Angular, Apple's Swift: Meet The Decade's Fastest-growing Developer Tech

Google's Angular, Apple's Swift: Meet the decade's fastest-growing developer tech Developer tools from Apple and Google have had the most dramatic impact on developers of any technology. The two most valuable companies in the world are also behind the two fastest-growing technologies that support their ecosystems. Stack Overflow's latest look at fast rising and falling technologies has found that Google's Angular framework for building web and native apps, and Swift, Apple's language for building iOS apps, have been by far the two fastest-growing developer technologies of the past decade. The developer community and help site gauges the success of different technologies by looking at the year-over-year changes in questions asked with tags such as 'angular', 'typescript', 'iPad', and so on. Only tags used in over 10,000 questions were included in the analysis. Other technologies among the fastest to attract developer interest included the iPad, which spiked after it launched in 2010 but its growth has since been in steady decline. The Google Brain Team's TensorFlow machine-learning framework for creating neural networks is off to a good start and is still rising. Android Studio, released in 2013, is also among the fastest to gain traction among developers. Stack Overflow data scientist Julia Silge notes there are good reasons for the massive growth of both Angular and Swift because each succeeded already popular languages. These were AngularJS and Objective-C, respectively. Android Studio, Angular, Swift and the iPad are examples of what "remarkable success" looks like for a new technology, according to Silge. She also takes a look at the "other side of the coin", which includes technologies that aren't necessarily remarkable failures and often the result of major platf Continue reading >>
