It's more zcash or monero style transfers inside, than ecash style, because it's transfers on an independent ledger. Ecash mints delink payment events; independent ledgers, you can just broadcast your tx p2p, from tor. Just a ledger/blockchain, with the exception you withdraw by interacting with the same guy you deposited at. Receiver doesn't have to be online.
Damn it's hard to describe this succinctly because it's a really a hybrid between an ecash server for btc, with its backing, but now trustless modulo an L2 consensus, and a sidechain for btc. All I can say is, read the paper.
