Curious what some of the bitcoin experts and those familiar with Monero think about this article.
I was unaware of this little detail they drop. I'm not unaware of the privacy tradeoffs with Lightning but didn't know Chainalysis had announced this.
The IRS wanted to be able to pinpoint behavior associated with a particular user to conduct investigations, and associate their activity with other users, gathering open-source intelligence such as their names, all packaged in a neat little GUI (graphical user interface).
Two companies won the contract, from Sept 2020 to Sept 2021, although only Chainalysis is of note as they were able to deliver a working product.
Three months after the contract ended, Chainalysis put out a press release advertising support for tracing Lightning Network transactions in December 2021.
