Eltoo / LN-Symmetry
Layer 2● Common
A proposed Lightning channel construction using SIGHASH_ANYPREVOUT enabling symmetric state updates. Any later state can replace any earlier state without penalty transactions, simplifying channel logic and enabling multiparty channels.
Technical Notes
Each state has update tx (rebindable via APO) and settlement tx. Later updates can spend any earlier update output. Eliminates toxic waste of old commitment transactions. Requires BIP-118 soft fork.
