**This week in privacy,** the Atlantic publishes an in-depth article on [the Chinese panopticon](https://www.theatlantic.com/magazine/archive/2020/09/china-ai-surveillance/614197). This article reminded me of [A Tale of Two Surveillance States](https://www.theatlantic.com/technology/archive/2019/05/the-us-and-china-a-tale-of-two-surveillance-states/590542/), a Crazy/Genius podcast episode that aired last year. The episode compares surveillance systems in XinJiang and East New York. Rite Aid deployed facial recognition in hundreds of stores according to a [Reuters special investigation](https://www.reuters.com/investigates/special-report/usa-riteaid-software/).

**In crypto news** , US national banks can hold [crypto](https://www.coincenter.org/the-occ-has-formally-stated-that-nationally-chartered-banks-can-hold-cryptocurrencies-for-their-customers/). Zcash gets a shoutout in this [Coindesk report](https://www.coindesk.com/central-banks-are-privacy-providers-of-last-resort). [Diario Bitcoin](https://www.diariobitcoin.com/criptomonedas-privadas-monero-zcash-dash-verge-komodo-similitudes-y-diferencias) did a great comparison of various privacy-preserving projects.That’s all for now folks. Have a great weekend!
