On Friday the Distribute 2017 took place in Hamburg. We from BTC-ECHO were there and give you some insights about the event.

At the Distribute short lectures were held within 30 minutes on blockchain topics. In addition to the presentation of new technical challenges, regulatory issues and even the global standardization of blockchains were discussed. Here are a few examples of presentations that we personally found interesting at the Distribute:

Blockchain for 3D printing

3D printing is one of the up-and-coming topics in the manufacturing sector and is changing many organizational structures in the industry, which until recently was dominated by a few large corporations. This is where the SAMPL project comes into play, which was presented by Chainstep and has Prostep AG as consortium and funding agency. The aim of this project is to develop a new blockchain solution that enables the secure exchange of production data. This means that producers can be distributed decentrally all over the world. If a product is requested at a certain location, it is possible to send a production file to the nearby producer, which enables him to produce exactly this original product. The blockchain also ensures a special security level for the print data due to the decentralized feature. What is decisive about the technology is that the print data is transferred via the blockchain, thus guaranteeing special data security. With this project, the consortium was even able to obtain federal funding. The project runs until the end of 2019 and is to achieve the goal of batch size 1 on an Ethereum basis, i.e. individual, exactly demand-oriented production.

Blockchain for submetering

Another industry in which blockchain compatibility has been considered is the current meter. Submetering refers to the measurement of the energy consumption of residential units. Using existing smart meters, startups try to create fair billing models using the blockchain. Since residential units are usually billed jointly and the costs are shared among the rental parties, start-ups try to determine fair amounts for each rental party on the basis of a smart contract. All of this is to be based on the Ethereum blockchain, so that the relevant data can be publicly viewed. However, this was also the biggest point of criticism during the discussion – after all, it also touches on many questions of data protection, many visitors said after the presentation.
