The entire e-CNY network is, according to the China Banking Association’s chief economist, built upon the concept of “one coin, two databases, three centers” (一币,两库,三中心). “One coin” refers to the e-CNY unit of currency, which researchers at one major state-controlled financial institution explain is essentially an “encrypted digital string representing a specific amount that is guaranteed and signed by the central bank for sale.” The “two databases” refer to (1) the central bank’s ledger that keeps track of all e-CNY outstanding and (2) all the e-CNY ledgers maintained by the network’s lower tier either locally or on the same cloud used by the central bank.
The e-CNY network’s “three centers” are all reportedly PBOC entities. Details on these are scarce. Reportedly, the first is the certification center, which will keep a database that maps real identities against all digital wallet users; the second is the registration center, which will track e-CNY ownership and transactions; and the third is the big data analysis center, which the central bank will use to monitor payment flows for financial risks and detect illegal behaviors.
