A summary of our talk covering IOTA basics, the ecosystem, and the future of Tangle technology. On the 20th December 2017, 120 people – from beginners to IOTA enthusiasts – met for the first German IOTA Meetup. It took place at the Starting Place in Cologne and kicked off around 19:00. To create a solid foundation for future meetups, the basics of IOTA were explained in a talk by Darius Torabian and our CEO & CTO Patrick Hütter. ## Summary of the Technology Behind IOTA After explaining the IOTA protocol, the speakers outlined the problems of "conventional" blockchains – limited transactions per second and the dependency on miners. This was followed by practical use cases, with Machine-to-Machine (M2M) economy taking center stage. ## The IOTA Foundation and Its Interfaces Patrick and Darius introduced the IOTA Foundation and its organizational structure. Unlike other cryptocurrencies, IOTA was established as a foundation – officially recognized in Germany. This could become a significant advantage in the future. The comparison of TPS (transactions per second) made IOTA's potential clear: while Bitcoin processes around 15 TPS, IOTA becomes _more efficient_ with each additional transaction. The speakers also covered IOTA's client libraries, which allow developers to interact with the protocol using common programming languages. ## Weaknesses and Running a Full Node Alongside its strengths, IOTA still had weaknesses at the time – such as the coordinator that was still required. The network was also slow in certain situations due to low transaction volume. To help compensate, the speakers explained how to operate a full node and thereby support IOTA's network. ## Q&A Session The meetup concluded with a Q&A session where attendees could ask questions about transaction sizes, network performance, and the roadmap. Overall, it was a very informative evening that built anticipation for the next meetup in January. ## Watch the Presentation 📹 IOTA Basics – Video Recording Watch the full presentation from the IOTA Meetup Cologne on YouTube.
