Reddit上的r/monero有讨论,结论是他们不能,美国国税局没有为此给他们付赏金。
In these kind of matters it is imperative to separate signal from noise. The fact that the IRS didn't grant the bounty to CT is basically a testament to the ineffectiveness of their tool.
"Nobody can deterministically trace Monero transactions yet" - Dave Jevans (CEO of CipherTrace)
r/monero would be a better place to ask this but to address your question, no ciphertrace can't actually trace monero deterministically, and according to the ciphertrace CEO on a podcast with a MRL researcher "no one can". Does this mean that they can get no data on transactions? No they definitely can get at least some info. But it's probably not using any techniques that aren't already well known to the Monero Research Lab.
In other words, they can collect data off the blockchain. The data they collect isn't enough to determine for sure transaction info. From what I remember they shoot for 80% probability. The "tracing" they are doing are probably using techniques that are already known to MRL that are going to be improved upon, not some bug in the monero protocol, and they aren't good enough to collect on the bounty that the IRS has put out for a monero tracing software https://decrypt.co/41411/the-irs-is-offering-you-625000-to-crack-monero
is monero still the best privacy coin?
