I am gonna need to use prude mod and began the download of the chain starting from march 2018 as recquired by lnd,
my question is which bitcoin client is able to do that and how to configure it for this procedure ?
I don’t believe any client can do this: how will your node know if a UTXO from before March 2018 was valid if it hast verified the full history of the chain?
When a node is bootstrapped, it will work through the blockchain’s history to build a UTXO set. Without being able to build and verify this UTXO set from scratch, there is no way to know that a UTXO is valid (without trusting someone else). For example, if someone opened a channel with your node, by consuming a UTXO from 2017, how would your node be able to determine the validity of that UTXO?
Even for a neutrino-serving node like btcd, the node still needs to have verified the entire history, in order to serve the LN node valid data.
