How long are you supposed to hold on to your digital identity? What does it even mean to have a digital ID?
I’m very positive about the future of cryptocurrency and blockchain technology and the good that it can bring to this world. But it’s not gonna be a straight line to mass-adoption. It’ll take a while for the good in people to cut through greed, inequality and evil powers. Continue reading “It’s gonna get worse, before it gets better”
Zero-knowledge proof cryptography is something that I have lots of interest in. It’s a type of cryptography that allow a prover to prove to a verifier that a certain statement is true, without revealing anything else apart from that statement. ZK-SNARKS, a variant of zero-knowledge proofs, is being built into Ethereum (it already exists in zCash). In this blog post I’ll refer to a very simple story that explain how zero-knowledge proofs work. Continue reading “Two balls and the colour-blind friend”
When developing dapps and smart contracts, it’s of great importance to have a good development workflow and to go through the right amount of testing and validation. In previous posts I’ve explained how to setup a local blockchain node for testing. While the ultimate goal is to deploy your dapp to one of Ethereum’s test networks, and then the main network, it’s very useful to be able to run your own full private network. This can be used for internal testing, verification and simulation, within your own team or company. In this blog post we’ll cover just that — how to deploy a private testnet and the basic components involved. Continue reading “Building dapps on Ethereum – part 6: deploying a private testnet”
Over the past week I’ve been working on part 6 of the Building dapps on Ethereum. Unfortunately, time hasn’t permitted me to finish all the development work and document it in blog post. Continue reading “Short update on my Ethereum dapp series”
It’s a common misconception that the creator and/or the developers are in sole control of the blockchains they create, such as Bitcoin or Ethereum. But in reality governance of blockchains involves different parties that act according to whatever incentive they have.
I’m really excited about the upcoming Drupal 8.5 release at the beginning of 2018. In the Workflow Initiative our goal is to include, in core, the rewritten version of the Workspace module. Continue reading “Plan to throw one version away, you will, anyhow”
On this blog I’ve talked a lot about blockchain technology recently. And while blockchains certainly are disruptive to how we use and agree on shared information, or run shared applications, they aren’t changing how we do general purpose computing, or personal computing. Continue reading “New era of personal computing”
Last week I attended DrupalCon Vienna. And I must say, it’s been one of the better and most positive DrupalCons in a long time. The past 12-18 months have been really tough on the community. There’s been a lot of fatigue, doubt and uncertainty in Drupal 8 as a product, as well as other issues in the community. But I really think we’ve come out of this period stronger than ever!
