Hi Bitcoin Developers,
I have been following the conversation in BIP 322 thread:
https://groups.google.com/g/bitcoindev/c/RCi1Exs0ZvQ/m/vp6Xo36aBwAJ and did
some research about all the undesirable things we can do with proposed
opcodes.
I think its possible to create a worse protocol in which withdrawal is done
to a personally identifying string. It can only be claimed by the user if
they generate a public key and get it certified by an identity verifier.
```
(pushes from scriptsig: certsig, bpubkey, txsig, 0)
IF (certsig, bpubkey, txsig)
<recovery_pubkey> -skip-
CHECKSIGVERIFY -skip-
<recovery_time> -skip-
CHECKLOCKTIMEVERIFY -skip-
ELSE
OVER (certsig, bpubkey, txsig, bpubkey)
CHECKSIGVERIFY (certsig, bpubkey,)
SHA256 (certsig, SHA256(bpubkey),)
<id> (certsig, SHA256(bpubkey), id)
CAT (certsig, SHA256(bpubkey)|id)
<tpubkey> (certsig, SHA256(bpubkey)|id, tpubkey)
CHECKDATASIG (1)
ENDIF
```
CHECKDATASIG would be replaced by CHECKSIGFROMSTACK if testing on signet.
Here's the link to read more about it:
