Reflections by Jochen Werne, Chief Development & Chief Visionary Officer Prosegur Germany (published in Prosegur Express 02/2021)
In all debates on analogue and digital means of payment, “trust” is always at the centre of the discussion: trust in the state-social order, which stands as a guarantor for stability and security of the fiat money issued. In this respect, some would almost like to marvel at how Bitcoin & Co. have managed to gain such trust in such a short time that a market capitalisation in the billions has been achieved. One of the points is certainly the technological confidence in the non-manipulability of the blockchain.
But is the blockchain really not manipulable, or is it rather a question of time before an attack will succeed? And what conclusions are central banks around the world drawing from this as they look at creating central bank digital currencies? Currencies designed to bridge the gap between the stability of analogue central bank money and the demands of our digital age.
Perhaps the solution for a trustworthy and generally accepted today and now lies in a hybrid model: in a cryptocurrency, in form of a stablecoin, that is 100 per cent backed by physical central bank money. This means that every digital token has a unique physical counterpart (euro). Due to the tradability of the tokens, the flexibility of book money is paired with the guarantee of physical central bank money. Last but not least, a regulated trustee function guarantees that the existing and securely stored central bank money is always paired with its digital twin. Thus. the best of both worlds is firmly united.
