> There are no sigificant obstacles to new code making use of taproot.

Using OP_SIZE on top of Schnorr signature doesn't reveal Proof of Work
behind it. But if it is done behind P2WSH, then it works much better (the
smaller DER signature is, the more Proof of Work it requires). Which means,
that if you want to have Proof of Work, and any conditions, then you are
forced to use P2WSH or something older (but older things are non-standard).
In theory, that kind of problems could be solved by new opcodes like
OP_CAT, but then, they would open more use cases, which may have unknown
side effects (like implementing BIP-300 or BIP-301 without any additional
soft-fork).

Also, if you use OP_CHECKMULTISIG, then it is guaranteed, that all
signatures can sign the same z-value, if they want (which is useful, when
ECDSA is used as a 256-bit calculator; if secp256k1 will ever be broken,
and OP_CHECKMULTISIG won't be disabled, then I guess using it as a big
number calculator will be the main use case). However, in Taproot, there is
OP_CHECKSIGADD instead, and then, each OP_CHECKSIG call is executed on a
different z-value, and it is much harder to force it to be the same for
different signatures.

Another combination, which can be used only in legacy scripts, is moving
coins from random P2PK outputs with out-of-bounds SIGHASH_SINGLE, from
known public keys, with unknown private keys. Then, even P2WSH cannot do
that, because z-value cannot be controlled by the spender in any reasonable
way (and different sighashes cannot be chained, because when txid inside
input can change, then next signature in the chain can be invalid; it is
hard to make a chain of one-input-one-output signatures, when all of them
would use sighashes SINGLE with ANYONECANPAY, because adding any input or
output to anything in that chain, will instantly invalidate all following
signatures).

&gt; &gt; You state that between 0.1% and 0.75% of all bitcoins in existenc=

&gt; I think you might have misparsed my email; I wasn&#39;t using one<br>

&gt; <br>

r<br>
&gt; the last three months is non-P2TR.<br>
<br>
The total output value created that is non-P2TR is irrelevant here: all tho=

outputs are being created by existing production systems. Obviously, they h=

no reason to rush to implementing taproot. Heck, as I just mentioned elsewh=

even P2PKH addresses are *still* fairly commonly used even though there are=

significant fee savings to upgrading. People just don&#39;t like upgrading =

What we&#39;re discussing here is a new scripting feature, that inevitably =
