+    * Just the addition of temporary contract id changes as discussed last time
+* Conjunctive Contract Interest

+  * https://mailmanlists.org/pipermail/dlc-dev/2022-March/000135.html
+  * **#Discussion**
+
+## DLC Research
+
+**#Query(Antoine)**
+
+* Channel jamming research
+  * if DLC start to be routed across the LN, they're going to constitute spontaneous channel jamming, as the liquidity along the path should be locked until the contract maturity.
+  * Further, the settlement might be conditional instead of binary like HTLC, i.e. not guaranteeing the payment of routing fees to node operators. Likely, routed DLCs would have to pay routing fees based on the length of their `cltv_expiry_delta`s. Antoine is happy to collect though on that subject
