LNHANCE bips and implementation

indeed. LN-symmetry is an other big thing it enables. (will try to dig up the contract, pretty sure someone already laid it out) it won’t do everything APO can, and that’s on purpose. just the most important things that are highly desired.

edit:

# S = 500000000
# IK -> A+B
<sig> <state-n-hash> | CTV IK CSFSV <S+1> CLTV

before funding sign first state template:

# state-n-hash { nLockTime(S+n), out(contract, amount(A)+amount(B)) }
# settlement-hash { nSequence(2w), out(A, amount(A)), out(B, amount(B)) }

# contract for state n < m
IF
  <sig> <state-m-hash> | CTV IK CSFSV <S+n+1> CLTV
ELSE
  <settlement-hash> CTV
ENDIF

CLTV ensures only a larger nLockTime transaction can spend the current on-chain state, the relative timelock for the last co-signed state’s CTV distribution is committed to in the settlement-hash
