Debate over blockchain technology is raging in many online and offline media at present. In principle, the technology constitutes a decentralised ledger system that can be coordinated via peer-to-peer (P2P) networks. Any ownership or security issues arising in connection with the decentralised transactions conducted across the ledger system are handled by P2P mechanisms as well, i.e. also without a central node. Ownership status is established via the digital exchange of cryptographic keys (public vs private), while fraudulent transactions can largely be ruled out with the help of the cryptographic 'proof of work' system. Using a proof of work, blockchain technology enables the rapid, inexpensive transfer of assets and financial products between individuals who neither know nor trust one another, without a compelling need for an intermediary to reduce existing information asymmetries.
