The government has to know about your transactions and has to know where your cash is in these cases. The point is privacy like _cash_ -- not like digital bank

  From the article: > An E-Cash device is any piece of secured hardware issued and/or authorised by the government for the purpose of receiving, holding, and transferring e-cash balances. > In contrast to ledger-based systems (including those that use a blockchain and/or distributed-ledger rather than a centralized ledge), which prevent double-spending by verifying unspent balances against a common record of all previous transactions, e-cash devices verify funds locally via a dedicated or trusted computing environment located on the device itself. > This allows it to facilitate both offline and genuine peer-to-peer transactions without generating transactional data or requiring the approval of third party intermediaries or network validator nodes.
