Blockchain at CeBIT 2018
Blockchain has the potential to revolutionize the corporate landscape. The World Economic Forum is predicting that, by the year 2027, worldwide about 10 percent of GDP will be processed using blockchain technology. In its highly noted “Hype Cycle for Emerging Technologies”

Gartner Research concurs, pointing to an impending blockchain breakthrough within the next five to ten years. This up-and-coming trend is reason enough for an entire day to be devoted to the topic at CEBIT 2018, in the form of the CEBIT Blockchain Summit on Thursday, 14 June, on the Grand Central Stage in Hall 27.
The summit will be opened by Dr. Wolfgang Prinz of the Fraunhofer Institute for Applied Information Technology, who will be addressing what all the blockchain excitement is about. For over two years, Prinz has been dealing with the technological nuts and bolts of blockchain, while developing and evaluating blockchain-based applications.
So, what does "blockchain" actually mean? In simple terms, it can be likened to a decentralized digital ledger that is distributed in millions of copies across the computers of all participants. The computers (or 'nodes') form a peer-to-peer network in which all transactions are verified, validated and stored as new blocks. To manipulate the data in the blockchain, hackers would need to hack each of the millions of computers in the network. Blockchain technology is therefore very robust and secure. IT experts like Germany's Friedemann Brenneis believe that decentralized blockchain networks have the potential to replace many sharing economy service providers. Brenneis, who publishes a blog on bitcoin and blockchain technology at , discussed the hype surrounding blockchains at the CEBIT Business Conference in Düsseldorf in mid-October this year. He noted that many technology ideas that seem highly promising to begin with end upcoming to nothing. For example, according to Brenneis, blockchain will never make it in the music industry because it poses a direct threat to the business model of the incumbent rights marketing agencies. The cryptocurrency Ethereum, for instance, would render their classic function as middlemen between performing artists and consumers redundant.
Blockchain technology also has the potential to replace lawyers by enabling smart contracts. With smart contracts, an algorithm determines what conditions (input) lead to what decisions (output). They function a bit like vending machines: the buyer makes a selection, tosses in the required amount of money and receives the selected product. In this analogy, smart contracts are software programs in which the contractual terms and conditions are stored. The contracts/programs are automatically executed and checked for correctness. They have the potential to revolutionize the business world.
Many other areas of the economy are also exploring the possibilities of blockchain technology. For example, CEBIT exhibitor IBM has launched a project with the world's leading container shipping line, Maersk. Their solution, which is based on the Linux Foundation's Hyperledger Fabric framework, will manage and track the papers and documents of millions of shipping containers worldwide by digitizing the supply chain process from end to end in order to reduce complexity and enhance transparency and the highly secure sharing of information among trading partners. When adopted at scale, the solution has the potential to save the industry billions of dollars.
