Rippled(Ripple Server)
written in c++ (open source in github)
core peer-to-peer server
provides json-rpc/wss apis of all ripple functionality
manage the RCP
connect to a network of peers
relay cryptographically signed transaction
maintain a local copy of the complete shared global ledger
3 running modes: stockserver/validator/standalone
Stock server - follows the network with a local copy of the ledger.
Validating server, or validator for short - participates in consensus.
rippled server in stand-alone mode - for testing. Does not communicate to other rippled servers

Ripple API

Ripple Address
address=>wallet
3 kinds of address
issuing address(cold wallet, highest security)
operational address(hot wallet, automated)
stand address(warm wallet, human-operated)

Ripple Account
The Payment transaction type is the only way to create new accounts
in the Ripple Consensus Ledger. To do so, send an amount of XRP
that is equal or greater than the account reserve to a mathematically-valid
account address that does not exist yet. When the Payment is processed,
a new AccountRoot node is added to the ledger

Ripple Funds Flow
Liquidity provider/parter/other customer -- redeem --> Issuing Address(highest security)
Issuing Address(highest security) -- issue --> Standby Address(human-operated)
Standby Address(human-operated) -- transfer(refill) --> Operational Address(automated)
Operational Address(automated) -- redeem --> Liquidity provider/parter/other customer
