### Pruned bitcoind node ### The `-txindex` flag
Running `lnd` connected to a `bitcoind` node that is running in prune mode is
not supported! `lnd` needs to verify the funding transaction of every channel
in the network and be able to retrieve that information from `bitcoind` which
it cannot deliver when that information is pruned away.
In theory pruning away all blocks _before_ the SegWit activation would work
as LN channels rely on SegWit. But this has neither been tested nor would it
be recommended/supported.
In addition to not running a pruned node, it is recommended to run `bitcoind` In addition to not running a pruned node, it is recommended to run `bitcoind`
