The Bitcoin Privacy Problem in a Nutshell

To understand how critical this privacy problem is, consider the following scenarios:

1. You are travelling through parts of a country with a medium to high violent crime rate. You need to use some of your Bitcoin to pay for something. If every person you transact with knows exactly how much money you have, this is a threat to your personal physical safety.

2. You are a business that receives a payment from a supplier. That supplier will be able to see how much money your business has, and therefore can guess at how price sensitive you are in future negotiations. They can see every single other payment you’ve ever received to that Bitcoin address, and therefore determine what other suppliers you are dealing with and how much you are paying those suppliers. They may be able to roughly determine how many customers you have and how much you charge your customers. This is commercially sensitive information that damages your negotiating position enough to cause you relative financial loss.

3. You are a private citizen paying for online goods and services. You are aware that it is common practice for companies to attempt to use ‘price discrimination’ algorithms to attempt to determine the highest prices they can offer future services to you at, and you would prefer they do not have the information advantage of knowing how much you spend and where you spend it.

4. You sell cupcakes and receive Bitcoin as payment. It turns out that someone who owned that Bitcoin before you was involved in criminal activity. Now you are worried that you have become a suspect in a criminal case, because the movement of funds to you is a matter of public record. You are also worried that certain Bitcoins that you thought you owned will be considered ‘tainted’ and that others will refuse to accept them as payment.
