Bitcoin transactions aren't anonymous, Blockchain is already public and thus transparent. As for Dash and Monero which are also mentioned in the article, that's another story. Whatever they're planning to do with Bitcoin blockchain, I'd be cautious about it. Russia is not the kind of country that I would trust with such a task. The level of corruption is high, the police is very militarised, human rights violations are not irregular. So there's a good chance the officials would use the system to track down someone's money for their personal reasons or to sell the data to someone. If there were a way to ensure the system is indeed only used to fight criminals, it's one thing. But since it's not the case, it's worrisome.
