The Bocholt-based start-up Teal wants to revolutionize e-commerce with its blockchain solution. Particularly interesting: Teal interlocks a patented artificial intelligence, whose functionality is based on the human brain, with a decentralized blockchain infrastructure as an e-commerce platform. In this new marketplace, the blockchain enables transparent transactions between user and brand. The sovereignty over the own data lies with the respective party. The AI ensures that search results and recommendations correspond to the actual wishes of the users.
With the Blockchain-Fintech Bitwala, customers can send money internationally – in the form of crypto currencies such as Bitcoin or Altcoin. Cash transactions on a block-chain basis are significantly faster and cheaper to process than with traditional payment providers or banks. The banking company founded in Berlin connects the current account with the Bitcoin Wallet: customers can use regular online banking services with a Bitwala account or trade with Bitcoins.
Ubirch uses the blockchain infrastructure to encrypt data traffic within the Internet of Things (IoT). The Cologne-based company wants to ensure that data exchanged between networked devices is securely packaged in the blockchain, thus strengthening confidence in IoT applications. Ubirch is taking advantage of the blockchain’s properties so that data stored in it cannot be subsequently changed without this being noticed.
Jolocom has developed an app that uses the blockchain to give users back control over their own digital identity. The app functions as a „smart wallet“ for user data. Users store personal data such as name, address and telephone number. This data is then stored unverified and decentral on the blockchain. Only when the user makes a purchase, for example, does he use the Jolocom app to specifically transmit only the data required for the purchase to the contractual partner. For online shops, this has the unbeatable advantage that the decentralised storage of user data automatically guarantees data protection.
