Thanks @sparkesy43

Hopefully we'll be doing the same thing, just not signing blocks for now.

As far as witnesses, I like the work of holger80, c-squared, and oracle-d, and think they all have something different to offer on top of the witness function.

c-squared added.

Meeee too! ;)
Thanks for the suggestion, @abn12345!
Cheers

Excellent choice!
