This week we had one of the busiest developers on the Steem blockchain, Holger. He lives in Germany and collaborates with creative minds around the world. There is so much content in this interview, from Steem Basic Income to Steem Monsters, that it is hard to keep track of all the innovation he is involved with. To make things easy here is a list of links to some of the projects @holger80 talked about with @jedigeiss:

On this episode of IdeaHub we had the good fortune of hosting Canadian super programmer @helo. He brought two interesting perspectives. As a developer, he talked about some of the very interesting projects he is involved in, such as Magic Frog and Volentix.

Then it was on to community building, as he spoke to us about some very exciting projects that he has seen both as a moderator for the Development category of Utopian, and as a member of the larger Open Source community.

This week's episode was somewhat Steem focused, as both projects are related to the blockchain. 

First we had one of the world's finest in the blockchain field, and a true pioneer in fighting abuse: @TheMarkyMark. He is always extremely well informed and lives on blockchains. We talked about his work in blockchain blacklists, as well as his new radio show on MSP Waves, Marky On The Air. You can check that show on the MSP Waves Discord at 1AM UTC each Wed.

Our second guest was @mcfarhat, owner of Actifit, one of the most exciting projects in the blockchain space. Actifit has recently made their own token, AFIT, available on Steem-Engine.com, which means it can be traded for Steem/SBD. Hear all about Actifit and how to be rewarded for fitness!

The show had two great projects this week:

Our first guests were @markegiles and @disregardfiat, talking to us about new ideas for their project dlux.io. This is a very exciting VR and AR blockchain project that allows users to easily create virtual environments in their builder and have others come in and interact!

Our second guest was [@DiggnDeeper](https://steemit.com/@diggndeeper.com), who shared with us an idea about connecting OpenBazaar with the STEEM blockchain. This will make it possible to use Steem and SBD on the OpenBazaar platform. A very interesting idea that has potential to be a win-win situation for both platforms.

This week, we had two excellent guests. The first was Sorbonne acting professor and dark matter scientist @lemouth. This is a man on the cutting edge of science, and you want to listen to see how you can help!

Our second guest came all the way from rural Florida - @ecoinstant. He currently has a task request on Utopian.io to help integrate Beam into his data searching project. There is a great need for better search tools for the Steem blockchain. @ecoinstant is working on it!

Major Steem power @surpassinggoogle was our guest, talking with Jan about two of his projects: ulogs.org and steemgigs.org@surpassinggoogle is a Steem veteran, active in many communities, and has even launched his own token.

Our first @elear talking about the current progress of the Utopian crowdfunding campaign, difficulties along the way and all other things that are currently keeping the staff busy at Utopian Headquarters.

As a second guest we were delighted to welcome @yabapmatt, one of the most productive developers around. He is the technical head behind SteemMonsters, Keychain and has also launched - together with @aggroed and @harpagon - the new SteemEngine tool, that allows you to create your own tokens based on the Steem Blockchain.

Our main guest this episode was @ecoinstant, talking about a project he already started: steemlogs.info. Following that, Utopian CEO Diego Pucci visited to talk about the ongoing Utopian Indiegogo campaign.

On this episode we had @fingersik, pitching an idea to us that could help archives and libraries around the globe. Fingersik is a computer scientist out of the Czech Republic and joined Steem in April 2017. 

@sorin.cristescu then stopped by to talk about his work with European Financial Transparency Gateway - https://eftg.eu/

Our main guest was Utopian's CEO @elear (Diego). He talked about Utopian's Indiegogo campaign. Our second guest was the amazing @helo. @helo talks about his work as a full-time blockchain worker and his exciting work at Volentix.
