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.
Zhuling Chen introduces the serious potential of side chains on a blockchain, for reducing the congestion that comes along with a higher volume of users, so that transactions are not slowed down. With this new technological infrastructure a parallel processing will be easier and allow a higher level of customization of dApps. It is the way to handle a high traffic and speed up the system.
Smart contracts work differently to what we’re used to, as they run and execute on the blockchain, not on your computer or smartphone, and this requires a change in thinking while writing code. Here are a few tips that should give you a clear idea of how to properly write smart contracts.
