【Abstract】 The “dust” problem will not only bring negative effects on the cryptocurrency system’s low efficiency. At the same time, hackers can also be used to infringe on users’ privacy or even use users’ privacy to obtain financial compensation. Different cryptocurrencies use different transaction models. Focuses on the unused transaction output models that are most affected by the “dust” problem. In this article, take the Bitcoin with the highest market price in the unused transaction output model as an example. Estimate the current amount and value of “dust” in Bitcoin through the historical state of unused transaction output sets, thereby showing the harm caused by the “dust” problem, and the dust reduction measures is put forward in the past.更多还原
