A forward and backward look at the ways various covenant proposals overlap, interact, and sometimes do surprising things. We'll touch on SIGHASH_ANYPREVOUT (BIP118), OP_CHECKTEMPLATEVERIFY (BIP119),
OP_CHECKSIGFROMSTACK(VERIFY), OP_VAULT(RECOVER) (BIP345),
OP_CHECKCONTRACTVERIFY, and OP_CAT.
Did you know that OP_VAULT is recursive?
Did you know that OP_CHECKTEMPLATEVERIFY+OP_CHECKSIGFROMSTACK has many of the same benefits as SIGHASH_ANYPREVOUT and then some bonuses?
Can OP_CAT alone enable Lightning Symmetry channels?
These questions and more will be answered as we explore quirky covenants.
