HOME TECH BLOCKCHAIN BLOCKCHAIN MEETUP BERLIN – AN EVENING FOR THE BLOCKCHAIN
The Berlin Bitcoin scene is big – as regular events like the Blockchain meetup Berlin, where BTC-ECHO was present, show.

Call me a trooper: After ten hours of work I first walked for an hour through the city of Berlin to the Blockchain meetup Berlin – Blockchain for Beginners – freely according to the motto “for Bitcoin I go miles away”!

But enough upliftment of my person: The cryptosoft event was worth it

Located in the Rainmaking Loft, about a hundred people fit comfortably into the room. And “for Beginners” may have applied to the first cryptosoft lecture, the two other lectures could also inspire passionate people from the Bitcoin and Blockchain scene like me. Altogether there were three cryptosoft lectures to listen to.

The first was the host of the evening, Brian Fabian Crain, who could say something to one or the other of the Podcast Epicenter Bitcoin. His lecture was an introduction to the topic Blockchain in general, which did justice to the title of the evening: The Blockchain theme was explained in a way that was generally understandable. Wasn’t sooo exciting for me now, but I wasn’t the target audience either.

IOTA – Blockchain meets crypto trader

The next crypto trader lecture came from Dominik Schiener. Dominik should be well known to some Blockchain enthusiasts: This year he took part in various events like the Blockchain Hackathon organized by Deloitte or the GTEC Blockchain Challenge. He took first place at the first crypto trader event and second place at the second – Dominik Schiener is a young genius.

At the Blockchain Meetup in Berlin, he talked about the IOTA project: “Reminiscent of Slock.it, Dominik keeps an eye on the Internet of things. He explained that we currently have two situations in the technical world: The majority of the devices are designed for a “stupid decentralization” that people need as mediators. A classic example is the lantern on the side of the road: it glows stupidly without anyone coming the way.

However, the currently existing counter-concept, smart centralization, also has its problems. Anyone who has noticed the hype about Pokemon Go in the last few days has noticed one of the consequences of smart centralization, so Europe could be banned from accessing it – even though, like many people who simply created another account, there were no technical reasons for it.

In contrast to these two models, Dominik has a smart decentralization in mind. An example of this in nature would be the anthill: The individual ants are of rather simple intellect, but together they create great things. Applied to the tech world, he has in mind a sharing economy 2.0, in which gadgets share (or trade with) resources via M2M communication. All devices that have a chip built in would be part of this version of the sharing economy, so that end users could theoretically lease them all (as I said: slock.it, ick listen to traps).

What he has in mind in concrete terms he makes clear to the presentation of a (fictional) autonomous supply chain: In addition to the content to be sold, the packages also contain sensors that independently search for the most profitable buyer possible, calculate the best delivery route to the customer and negotiate the shipping terms accordingly. Man would only stand at the ultimate beginning and end of this supply chain.

Interesting vision, but what would it take? Dominik says that it would simply need the blockchain: Such a M2M communication would require a decentralized system in which data transfer and money transfer could be mapped. In concrete terms, this blockchain would have to be able to realize m2m microtransactions as quickly as possible, it would have to be extremely secure, lightweight, scalable and modular, it would not have to have any transaction fees, and there would have to be a possibility for automation. Dominik does not have Turing Completeness in mind; a large part of the required automation would be realized by simple IFTT structures (If this then that).

Music of the future? Well, that’s exactly what Dominik, among others, is working on in the IOTA project. Strictly speaking, IOTA is not a blockchain, but a construct that he calls “tangle”: It is a network that resembles more a ball than a chain. In this network, the individual transactions that are individual nodes in this tangle would validate each other: In order to get your transaction verified by others without another fee, you would have to use two T
