The lightning network is(can be) trustless and decentralized. It uses time based transactions to transfer bitcoin. It does have complications though. If you send money with the LN you have to regularly(about once a week) connect and verify that no one is trying to cheat you. If you only receive through a channel you don't have to do this. In principle it's possible to delegate this to a third party. Another complication is that sending funds to an arbitrary party involves finding a path through a graph of nodes. We'll see how this works out in practice.
