Dev Update March

big-data blockchain continuous-integration IoT technology

Welcome back to our monthly development update. A few weeks ago, in Transmission 5, our CEO, Henri Pihkala, announced that we’d managed to halve the development time needed to create a functioning Marketplace. I was with him in London when he made the announcement and presented the rest of our plans, to create a larger decentralised infrastructure, to dozens of developers at King’s College London.

Most development teams fall far behind deadlines, so I won’t lie. It’s been super tough over these last few weeks and months, trying to make sure we were able to race ahead. It’s placed a lot of pressure on us but thankfully we now have even more developers to add to our core team.

Consequently, we’re really happy to welcome Mikhael Santos, Matthew Fontana and Tuomas Koponen to the Streamr development team! Mikhael has started working on DevOps, whereas Matthew and Tuomas have started developing the Marketplace UI.

Below you’ll find the rest of the technical progress the team’s made during the last month. If you have any questions, please feel free to join us on our dev orientated Rocket Chat. We’d love to hear your feedback.

Oh, and April’s development will be published just before the team heads off to New York, to Consensus 2018. So, stay tuned – we might have a few surprises in store for you then.
