What Are The Applications And Use Cases Of Blockchains?

What Are the Applications and Use Cases of Blockchains? Blockchain technology is a revolution in systems of record. Bitcoin is historys first permanent, decentralized, global, trustless ledger of records. Since its invention, entrepreneurs in industries around the world have come to understand the implications of this development. The nature of blockchain technology has got imaginations running wild, because the idea can now be applied to any need for a trustworthy record. It is also putting the full power of cryptography in the hands of individuals, stoppingdigital relationships from requiring a transaction authority for what are considered pull transactions. For sure, there is also a lot of hype. This hype is perhaps the result of how easy it is to dream up a high-level use case for the application of blockchain technology. It has been described as magic beans by several of the industrys brightest minds. There is more on how to test whether blockchain technology is appropriate for a use case or not in ourguide "Why Use a Blockchain?" . For now, we turn to a discussion of the development of blockchain technology for how it could be useful. Cryptographic keys in the hands of individuals allow for new ownership rights and a basis to form interesting digital relationships. As weve discussed in our guides "What is Blockchain Technology?" , "How Does Blockchain Technology Work?" and "What Can a Blockchain Do?" , blockchains provide an opportunity to establish a strong system for digital identity. Because it is not based on accounts and permissions associated with accounts, because it is a push transaction, and because ownership of private keys is ownership of the digital asset, this places a new and secure way to manage identity in the digital world that avoids exposing us Continue reading >>

What Is Blockchain Technology? A Step-by-step Guide For Beginners

What is Blockchain Technology? A Step-by-Step Guide For Beginners Angel Investors, Startups & Blockchain developers... Is blockchain technology the new internet? The blockchain is an undeniably ingenious invention the brainchild of a person or group of people known by the pseudonym, Satoshi Nakamoto . But since then, it has evolved into something greater, and themain question every single person is asking is: What is Blockchain? By allowing digital information to be distributed but not copied, blockchain technology created the backbone of a new type of internet. Originally devised for the digital currency , Bitcoin , the tech community is now finding other potential uses for the technology. Bitcoin has been called digital gold, and for a good reason. To date, the total value of the currency is close to $9 billion US. And blockchains can make other types of digital value. Like the internet (or your car), you dont need to know how the blockchain works to use it. However, having a basic knowledge of this new technology shows why its considered revolutionary. So, we hope you enjoy this, what is Blockchain guide. The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value. Picture a spreadsheet that is duplicated thousands of times across a network of computers. Then imagine that this network is designed to regularly update this spreadsheet and you have a basic understanding of the blockchain. Information held on a blockchain exists as a shared and continually reconciled database. This is a way of using the network that has obvious benefits. The blockchain database isnt stored in any single location, meaning the records it keeps are truly public and easily verif Continue reading >>

Blockchain For Developers: Is It Right For Your Application?

Blockchain for developers: Is it right for your application? Blockchain is a hot technology right now. Unfortunately, lots of pilots of blockchain technology have been for applications that haven't really been a good fit for the technology, ones where traditional relational databases, such asMySQL,work just as well, and perhaps even better. So how do you know if blockchain, which has been promoted for secure transactions , is a fit for your application project? The key to answering that question lies in understanding the fundamentals ofBitcoin and blockchain. Only when you understand the benefits and drawbackscan you addresswhat criteria you might use to identify projects that are truly suitable for blockchain technology. Best Practices for Building a Secure Data Lake A blockchain is the data structure that the Bitcoin cryptocurrency uses for its public ledger, where transactions are recorded. Somewhat curiously, the term blockchain does not appear in the original description of the Bitcoin protocol (neither does the term block chain). The closest that it came was using the term chain of blocks in a comment in the source code for its implementation. Because of this fuzzy origin, there is no clear definition of exactly what a blockchain isand is not. And while few people would dispute that Bitcoin uses a blockchain, opinions on other uses of the same technology are more divided. Some even argue that the only appropriate use for the term is for Bitcoins public ledger. When most people talk about blockchains today, they mean a distributed database comprising a collection of blocks of data, each of which contains a timestamp and a cryptographic link to a previous block, in addition to the other data that it might store. And they often mean a database that is readable by ma Continue reading >>

Why Use The Blockchain Instead Of A Database? What Gives Tokensvalue?

Why Use The Blockchain Instead Of A Database? What Gives Tokensvalue?

Why use the blockchain instead of a database? What gives tokensvalue? A primer on blockchain and token concepts for beginners. I see these questions asked all the time by novice investors entering the space, either for specific projects, or as a general question. So I thought Id attempt to write a detailed yet basic explanation on the utility of tokens, and what justifies the use of a blockchain. Basically, blockchain embodies a lot of game theory and incentive models. In order for a blockchain network to be valuable or useful, it has to have participants in a network, it would be worthless if Bitcoin only had me and you using it, theres not much value there in a barren network with not much utility. In order to secure participants, there needs to be some sort of incentive to attract them, the most common method is via issuance or reward of the token used in the network, the more participants, the more decentralized it is. So why not just a database, why do these projects need a blockchain? There are a few key benefits to decentralizing things instead of keeping it in a centralized server/database: Having records and data decentralized, and deployed on a blockchain makes it virtually impossible for any one party to tamper with data or records. Versus how it is now, if you host your data on lets say, your computer, you can easily edit that file, before you send it to someone else, how can I ensure I can trust you? Traditional servers or data are generally centralized, making it a likely target for malicious attacks. Just look at the Equifaxs security breaches and other cybersecurity concerns arising in recent times. Instead of having a single or limited # of servers hackers can attack, decentralization via the blockchain greatly increases the difficulty. The more partic Continue reading >>

17 Blockchain Applications That Are Transforming Society

17 Blockchain Applications That Are Transforming Society

17 Blockchain Applications That Are Transforming Society Angel Investors, Startups & Blockchain developers... The early internet dealt with intangibles. You sent or received emails, corresponded on forums, read and distributed articles. This modern internet deals with assets, your most valuable immediate items that you can touch and want to protect. These assets are stored in encoded form on a network-to-network chain called the blockchain or ledger, where each participant sees who you do business with. This not only protects your business dealings and prevents theft, but, also, simplifies your affairs, quickens the process, reduces errors, and saves you from hiring a third party. This decentralized blockchain system is going to change your life from the way you transact business or manage assets, to the way you use your machines, vote, rent a car, and even prove who you are. Along the way, it will transform banks and other financial institutions, hospitals, companies, and governments among others. Heres what the blockchain does and what it means to you. At its simplest, cryptocurrencies, or digital coins, are coins that are passed through an electronic network. You can make transactions by check, wiring, or cash. You can also use a type of virtual currency, most famously Bitcoin (BTC) but also Litecoin, Peercoin, or Dogecoin, among others, where you use an electronic coded address to make the transaction. The more valuable the transaction, the more you want to protect it. Traditional systems hire a mediator, such as a banker or a remittance company to ensure trust. Islanders of Yap had a different solution. They kept a mental record of who owned what and referred to this distributed community record when disputes arose. The blockchain is this community record on a wid Continue reading >>

Thus, token owners can sell them for other cryptocurrencies for example the highly popular Ether and Bitcoin and they can even convert them to fiat currency if they want to. So why is this interesting? Many startup founders currently want to leverage the opportunities that a native token offers in particular, gain traction for the respective startup and app. Using a native token inside an app can serve many purposes: Users can pay or reward each other, token ownership can be attached to voting rights, or token owners can receive a share of the startups profits. All of this contributes to the establishment of a loyal and lively community inside the app ecosystem. A lot of startup teams have recognized the value of native tokens for their system. However, a critical mass of token owners and participants need to be reached in order for the community effects to come into play. Startups have quickly noticed that there are certain measures that can speed up the path to a functional community. In the early days of their businesses, they would award their tokens to early adopters in exchange for a little p Continue reading >>

Create A To-do List App Using Blockchain - Ibm Code

Create A To-do List App Using Blockchain - Ibm Code

Create a to-do list app using blockchain Create a web-based to-do list application using Hyperledger Fabric V1.0 Last updated | By Ishan Gulhane , Kevin Hoyt Hyperledger Fabric is a shared, immutable ledger for recording the history of transactions; its fostering a new generation of transactional applications. This developer journey shows you how to perform traditional data store transactions with blockchain and migrate from Hyperledger Fabric v0.6 to v1.0. Youll implement a web-based to-do list application that enables you to browse, read, edit, add, and delete list items. This developer journey helps you understand how developers perform common transactions of creating, reading, updating and deleting against a Hyperledger Fabric blockchain. It also helps you migrate from Hyperledger Fabric V0.6 to Hyperledger Fabric V1. This web-based client is designed around Polymer 2 Release Candidate, which acts as a polyfill for assorted web components specifications. These specifications include Custom Elements, Shadow DOM, HTML Imports, and HTML Templates. As Hyperledger Fabric supports cross-origin resource sharing (CORS) out of the box, the web client communicates directly via HTTP/JSON. As requests arrive on Hyperledger Fabric, they are mapped to a specific smart contract written in Go. There are two types of requests that can be made. The first is an invoke request, which will take place asynchronously on Hyperledger Fabric, returning only a transaction identifier. The second is a query request which will return some value. This project uses invoke requests for create, update, and delete operations, and query requests for read operations. The to-do list application that you will create is designed to help you understand how common transactions needed by business processes Continue reading >>
