The proposal is meant to improve designs for [Eltoo](/topics/eltoo)-style Lightning channels, [Ark](/topics/ark)-like systems, [vaults][/topics/vaults], payment pools, and other shared-UTXO constructions that benefit from predictable transaction trees and more flexible signature checks. + +LNHANCE remains a proposal.
