📝 Original message:Thank you, that's an interesting application of OP_CTV.
Perhaps worth pointing out that this does not require OP_CTV but could also be
enabled by other covenant constructions. For example, it seems like
ANYPREVOUT-based covenants provide similar benefits. The script of the Taproot
leaves could be set to
<sig> <G> CHECKSIGVERIFY <CET_i> CHECKSIGVERIFY
where <sig> is an ANYPREVOUTANYSCRIPT signature of the CET for public key P = G.
When using nonce R = G, signature creation has negligible computational cost (s
= 1 + H(R, P, m)). A downside compared to CTV is the additional overhead of 64
witness bytes (<sig>).
