Eoin Treacy's view -
How will data be used by central banks and how will the central bank reassure people about the privacy of their data?
The data you are going to collect, there are two sides to it. On one side, the data that they're going to collect, given they are going to be able to engage the complete economic activity of a country in realtime, that data will be recorded on a blockchain-type network, distributed ledger, we don't know exactly. So the government will have access to all of that. On the [other] hand, it will enable the central bank to do their job more effectively. Because rather than having a lag in economic data, they're monitoring all the spending, the transactions, money supply, inflation implications, all in realtime... Tracking where people go in the world, because CBDC will be available to Chinese as they do business in other countries. It's almost a sort of a way to track an individual. So there are big alarming questions that need to be properly considered when it comes to privacy and anonymity.
The technology is there to enforce anonymity, but it's a question of are they going to implement it? Is that something that they're going to build into their currency? Time will only tell if different central banks come up with their versions of digital currency, as they say there is no one-size-fits-all, they're all going to be different and likely to reflect the values and culture of their citizens. Are we just going to accept that all governments get to have this data like we've kind of accepted with tech giants like Facebook? No one has really done anything about it.
A classic blockchain is a public ledger. There is a clear record of all transactions, but not who participated in them.
It would be comparatively easy for a state to create a digital currency that attaches identity to the ledger.
That will allow governments to track every transaction in even greater detail than they do already.
