# Full Blocks

If your Lightning node is backed by a Bitcoin full node, the operation is straight forward: call the appropriate methods on ChannelManager and ChainMonitor as blocks are connected and disconnected. LDK will handle the rest!

So what happens? The ChannelManager examines the block's transactions and updates the internal channel state as needed. The ChainMonitor will detect any spends of the channel funding transaction or any pertinent transaction outputs, tracking them as necessary.

If necessary, LDK will broadcast a transaction on your behalf. More on that later. For now, let's look at the more interesting case of pre-filtered blocks.
