Corda was developed by the R3 consortium  in collaboration with more than 200 technology and industry partners. According to the manufacturer, Corda is an open-source blockchain designed specifically for enterprise use. Unlike other blockchain solutions, information is only shared between the parties that actually need it. This information is referred to as "Shared Facts" in Corda. This article shows how to create, distribute and historicize such shared facts.
Few technologies have made such a strong impression in regards to their implementation as Blockchain. The image of blocks lined up as a chain is literally embossed in people’s minds. Many conversations about Blockchain revolve around this image and the actual implementation. That's all nice and fun, but it also carries the risk that the key issue is passed over in the discussion: the application. Therefore, the goal of this article is to explore that issue above all. We need to clarify when and why a blockchain solution makes sense. Then, using Hyperledger Fabric and Hyperledger Composer, we will also implement a small use case directly.
When it comes to traditional databases, the blockchain supports a completely different paradigm. For the first time in computing history, we have a datastore in which we can have absolute certainty about a data item’s creation date and can be absolutely certain that the item has not been modified. How can we integrate the power of blockchain into databases?
Bitcoin, Litecoin, Ether, ICO ... As the fog of buzzwords, hype and speculation slowly gives way to reality, the fledgling technology is being faced with new challenges. Uncontrolled public networks are not the right choice for every application, and in addition to environmental considerations, economic concerns regarding high energy consumption by miners also play a role when choosing a technology stack.
Is blockchain technology the next big thing in cybersecurity? The implementation of blockchain as a solution for cybersecurity can limit the number of targets a hacker can attack. The process of decentralization creates a more secure system and prevents easy access for cyber-criminals and potential fraud.
Can blockchain transform the world? Before we can answer this question, we need to understand what this technology can and can’t do, what it is and what it isn’t. Therefore, we have to go back to basics and explore the fundamentals in order to eliminate all misconceptions about blockchain.
Anyone who has been dealing with blockchains in the business environment in recent months knows this: Smart Contracts are almost like magical problem solvers, from the automated billing of solar power and other goods deliveries, to the independent triggering of contract penalties in closely monitored areas such as the agreed maximum temperatures of a cold chain. The potential applications are versatile, and they even seem endless. But how much of it is true and how much is just hype? And above all: What is the actual technology behind it?
Blockchain-based applications have been the talk of the town for several years. It is always very easy to talk about the "decentralized revolution", and management is sure to have a number of great ideas on how you can improve your own product with a decentralized app (DApp). The fact that tangible technical issues can appear along the way is not necessarily obvious at first glance. This article therefore introduces the reader to the "oracle issue", which is the seemingly simple process of making entries in blockchain applications.
Even as market speculation takes over the conversation around blockchain and cryptocurrencies, developers remain focused on building real businesses. For the blockchain industry, 2018 has been the year of infrastructure. Next year, the potential of distributed ledger technology will be felt by the mass market as the industry turns its attention to dApps.
