The internet makes information available everywhere, but it also comes with a downside. If a user wants to gain access to specific pages and apps, they are often forced to hand over personal information to third parties, which can lead to undesirable consequences. This article examines the current situation online and describes how decentralized technologies could empower individuals to take back ownership of their data.

One of the defining aspects of a public blockchain is that anyone can add information to it. However, before it is added, the information must be verified. All cooperating nodes in the network must agree on the definitions of valid, and invalid, information. For example, in the case of Bitcoin, there must be a consensus on what defines a legitimate transaction. When the new information is deemed valid by all participating nodes in the network, then the consensus is reached. This article explores how a decentralized network could achieve consensus through two different algorithms: proof-of-work and proof-of-stake.

There’s a lot of blockchain-related development already in progress. Start-ups that focus on its various aspects are popping up everywhere. Companies in all sectors are looking at its thread to determine what it could do for their business. There’s even a new career role flying around on LinkedIn, the "blockchain consultant.” So, hype or not, clearly, this trend is gaining some traction.

But how “enterprise-ready” is blockchain technology? 

This three-part series explores how Wechat, the Chinese alternative to WhatsApp, is transforming the on- and offline lives of Chinese consumers and forcing companies to reconsider their marketing and sales strategies.

Part I compares WeChat to WhatsApp and explains why a presence on WeChat matters for any Chinese-facing business. Part II provides an overview of WeChat’s most essential features, describing how it’s typically used day-to-day. It also explains how companies can use WeChat to improve their business in the Chinese market.

These days, you can’t mention “blockchain” without someone else bringing up bitcoin. Of course, it’s an intriguing topic. A digital coin, with no value at all, suddenly skyrockets and makes people rich, out of thin air! It must be a bubble, scam, fraud - even criminal!

Or is it?

Imagine a world without WhatsApp. It probably wouldn’t change much, because WhatsApp has been slow to implement new features that would enable its platform for e-commerce, banking or marketing purposes. In September 2017, the first reports of WhatsApp’s new business-to-consumer (B2C) features arose, with customer support as one of the central axes on which it could swing into the enterprise jungle. This seems to be it for now, as no new reports of other B2C functionality have come out. And, with local and European privacy laws lurking just around the corner, it might take some time before WhatsApp can fly in a B2C context. Until then, WhatsApp will remain just a messaging application.

Although container technology has been around for more than a decade, it was Docker that made it easy to use. The impact on the software industry has been tremendous. It improved the speed of software delivery. It did away with manual handovers between dev and ops. It made the deployment process 100% reproducible. And last but least: Once you put your application in a container, you can run it anywhere. On-premise or in the cloud. In this article we give you 8 reasons, why container technology is a fundamental building block for a multi-cloud strategy.

The surprising truth about success (and why some people never learn from their mistakes), is that it has everything to do with failure. Failure is not the opposite of success, it’s an essential part of it. It’s through failure, in a controlled and tested environment, that we learn and improve; a core principle of continuous delivery. Cloud-native technology speeds up the development cycle so that we can fail earlier and faster. But companies must also maintain quality, increase velocity and change the way they design and deliver their software to achieve a full cloud impact. This article explains how to do each of these three.
