Right. There are minor trade-offs to be made with regards to that design
point of OP_CHECKSIGFROMSTACKVERIFY. Fortunately this covenant
construction isn't sensitive to that choice and can be made to work with
either implementation of OP_CHECKSIGFROMSTACKVERIFY.

Interesting. I have implemented OP_CHECKSIGFROMSTACKVERIFY in a different way
from the Elements. Instead of hashing the data on stack, I directly put the 32
byte hash to the stack. This should be more flexible as not every system are
using double-SHA256

Hi all,
It is possible to implement covenants using two script extensions: OP_CAT
and OP_CHECKSIGFROMSTACKVERIFY. Both of these op codes are already
available in the Elements Alpha sidechain, so it is possible to construct
covenants in Elements Alpha today. I have detailed how the construction
