Dear Bitcoin Devs,
As mentioned previously, OP_CAT (or similar operation) can be used to make
Bitcoin "quantum safe" by signing an EC signature. This should work in both
Segwit V0 and Tapscript, although you have to use HASH160 for it to fit in
Segwit V0.

Well I believe we should ban partial Turing-completeness, but allow total
Turing-completeness.
I just think that unlimited recursive covenants (with or wit
I don't think Elements engineering decisions or management timelines should
have any bearing on what Bitcoin adopts, beyond learning what
works/doesn't. Same as litecoin, dogecoin, or bitcoin cash :)
With my understanding of elements it makes sense that you wouldn't want to

Nothing here refutes what I have said. Furthermore it relies on the
assumption that all assets and liabilities are provable. This is clearly
prohibitive.

heh -- I pointed out these evil multisig covenants in 2015 :)

I'm relatively unconcerned by it except to the extent that mining
centralizes to the point of censoring other traffic.
Overall, I think
you should check out some of the earlier work done here:
https://github.com/olalonde/proof-of-solvency#assets-proof
to be honest, if any exchange supported that proof, it would be more
than enough.
there's really no way to prevent a smash-and-grab, but this does
prevent a slow-leak

If the main outstanding issue is whether to split R or S, I think as far as
Elements goes, I am inclined to go with the CAT option regardless of
whether Bitcoin chooses to split R/S or not (not that I'm necessarily a
decision maker here).
The issue here is that (a) Elements already has CAT, and (b

After some brainstorming about the possible drawbacks of enabling
covenants, I have also slowly become more comfortable with the idea of
"unlimited" covenants. AJs example clearly shows that _all_ possible
"misuses" of covenants are already possible by Multi-Sig today, so it's not
a new vector that

Sure, but anyone can easily see that transaction happen and can discount
that part of the attestation. The same isn't true on lightning.

Are they? Are you implying that anything that enables covenants is
equivalent to enabling OP_CAT? Generally when I think about enabling
covenants, I'm thinking more about OP_CTV (or so
