The lightning network is a so-called “offchain” network. It does not transport Bitcoins to the blockchain, but operates through “payment channels”. These increase the privacy of transactions and the scalability of the system, but so far they still offer users reduced convenience and security.
An alternative to the lightning network is a fiduciary wallet such as BitBucks, which carries out transactions for users within its own system. This is less autonomous, like lightning, however results in the same effect in terms of scalability and can be better integrated into a convenient user interface.
