🗒️ Conversation Summary: A bug in Taproot allows the same Tapleaf to be repeated multiple times, incurring different Tapfee rates. Mitigations include knowing the entire Taptree, implementing RBF, and signing the entire tapbranch instead of the tapleaf. Miniscript can help prevent an attack in multiparty transactions, and uncompressed keys are banned.
