Lightning Labs Launches LayerTree, a Non-Custodial Bitcoin Scaling Plan

The significance lies in the trade-off being attempted: covenants let Lightning Labs push shared-UTXO scaling toward a million users while keeping custody non-custodial, and removing the online requirement and timeout expiry addresses the two frictions that have kept Lightning impractical for casual recipients. That said, the design's dependence on covenants puts the open question squarely at the protocol level, since Bitcoin has not activated them. Whether the architecture is adopted therefore hinges less on Lightning Labs' engineering than on whether covenant proposals advance — and on how shared UTXOs behave under real fee pressure and adversarial exits.
