Hey Antoine,
Thanks for the post. Based on my read of what you're describing
nothing in particular in your attack is specific to CTV. In your example
script, you're not making use of the template hash or OP_NOP4.
As far as I can tell, the DoS you're describing basically affects all non
witness v1 activity on bitcoin - i.e. some malicious user filling blocks
up to their sigops limit to deny other users service.
Given that probably most activity on bitcoin is not witness v1,
I don't see how this is a CTV-specific issue.
Thanks,
James
