In an October issue of Deutsche Bank's Flow magazine, the German institution said it had explored an "innovation lab" to investigate the potential of the blockchain.
Deutsche Bank highlighted that the adoption of the blockchain would face "significant legal and regulatory barriers" but recognized that it could be massively disruptive to banks.
"On one level, this is a wake-up call to the banking industry. Buying and selling across the globe with a cryptocurrency requires no identification, no bank account and no credit card. It pays no foreign exchange fees or banking charges, meaning you could be a bitcoin billionaire without ever having spoken to a bank," the investment bank said.
"It could also, of course, be a threat to investments in Uber and Airbnb – and all fintech start-ups that are essentially intermediaries using banking's payment rails."
