# - Old channel state is toxic and you can loose all your funds, if you or someone

# else closes a channel based on the backup with old state - and the state changes
|

# often! If you publish an old state (say from yesterday's backup) on chain, you
|
|
# WILL LOSE ALL YOUR FUNDS IN A CHANNEL, because the counterparty will publish a
|
|
# revocation key!
