The nature of stock market data is determined by ups and downs. Geopolitical effects and investor sentiments influence prices. Today you have access to Terabytes of data in real time. But the human brain is not capable of processing this amount of information. As a result, traders and risk managers get overrun by data.

In my last post I talked about how to go serverless with an Ethereum based NodeJS oracle by combining FaaS and Blockchain. Today I’m going to demonstrate how to add more logic to an Ethereum based smart contract.

Why is an Ethereum based contract not smart by default?

The make long story short: a smart contract can only be as smart as the programming language allows it to be smart. And Ethereum’s programming language Solidity is very, very basic. It has everything on board to send Ether, store data compliant and forever and it allows programmers to do basic mathematical operations. That’s it.

But that doesn’t make a contract smart…

Why go serverless with FaaS + Blockchain?

Back in August 2018 Forrest Brazeal did an interview with former AWS Lambda GM Tim Wagner entitled “From Serverless to Blockchain”. They discussed the benefit of merging serverless computing and blockchain technology. These are the two main statements:

I really think that there are two disruptive technologies that are changing how we build and operate businesses. One of them, of course, is serverless.

The second technology that I think is really disruptive and has an amazing potential for impact is blockchain. Now, that one’s still very nascent.

According to Tim merging the capabilities of both blockchain and serverless computing will…

some fun before x-mas and a big thank you to all of the 36.000 people who read my blog in 2017

Last week my wonderful wife and I faced another classic situation: I spent my day with multiple meetings, calls and emails while visiting customers and colleagues in two different cities, while she returned from work, took care of the kids and organized four whole lives. …


... me and my team were asked to fix a huge problem. We were always called when the situation has already escalated. In this specific case the involved people could be divided into  three groups:

  1. people affected by the major issue were extremely demanding and angry
  2. managers who got involved because of this long-lasting outage got more and more nervous and increased the pressure on their domain experts
  3. domain experts who had to fix the issue and who were forced to participate in numerous reporting calls in which the managers increased the pressure in order to get immediate results

Here’s to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes. The ones who see things differently. They’re not fond of rules. And they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can’t do is ignore them. Because they change things. They push the human race forward. And while some may see them as the crazy ones, we see genius. …
