๐ Summary: Payment pools and channel factories face limitations in interactivity, affecting user fund security. Proposed solutions include introducing a coordinator or partitioning balances, but these may not be economically practical. A potential solution is to prevent off-chain group equivocation by editing the funding utxo to allow for registration of new off-chain subgroups. CoinPool's idea of including user pubkeys and balance amounts in Taproot leaves could be used for privacy-preserving payments and contracts. OP_EVICT requires participant cooperation for a single participant to withdraw funds, which may not be safe. TLUV or MERKLESUB offer more flexibility, but no sound covenant proposal combines TLUV and EVICT-like semantics. The best direction to solve interactivity issues is still uncertain.
