04:11 < harding> I'm looking at the Morehouse DoS vulnerability.  What state does the fundee need to store until the funding transaction confirms or is abandoned?  It seems to me that a fundee with random access to the UTXO set (e.g. a full node or client of an electrum server) could just require the funder include in their channel_ready message the txid:vout to the funding transaction plus enough data for the fundee to reconstruct their per-channel keys.  That 
04:11 < harding> would make single-funding stateless on the fundee side for those types of nodes.  That doesn't help with BIP157/8 clients, although that maybe works too if you've cached the last 2,016 block filters.
04:26 < realtbast[m]> We'll need a bit more data than that, for example we exchange funding public keys during the first step of the protocols, and the fundee needs to store the corresponding private key.
04:26 < realtbast[m]> But you're probably onto something: if those keys are derived using BIP32, the fundee could potentially share that key path and it would be the funder's responsibility to send back that key path in `channel_ready`. Maybe the funder can play games there, but the fundee could instead just give an encrypted blob to the funder (encrypted with a key derived from the fundee's master seed and a path created from the funder's `node_id`), that
04:26 < realtbast[m]> the funder would send back in `channel_ready`. Even there, we'd need to be careful about potential replay on a different channel, but that can probably be handled somewhat easily, it's worth looking into!
