HSBC says the blockchain could be used for 'helicopter money'
Here's how they think the blockchain could help with that:
If we move towards an economy where all transactions become recorded in real-time on a Blockchain type of technology, it will not be too dissimilar to the current eco-systems that many ecommerce giants have around the globe. Online e-commerce stores are able to give out loans to merchants without collateral, because they know all the flows already from the merchants’ point of view: from how much people are spending to the conversion rate of pages viewed to purchases. In the same way, a modernised monetary transmission system, based on real-time big data analysis through Blockchain, could allow the government to balance the economy more efficiently and systematically.
In short, the blockchain would allow the government to know a huge amount more about what's actually happening in the economy.
