Can we make a list of all the distinct arguments against UDAs.
Because I think you are bring up a different one from earlier. And its hard to address these things when the topic at hand keeps switching from one argument against to another.
-
You are bringing up the top heavy argument that having UDAs risks the chain being insecure.
This is a long standing debate for other chains, including ethereum pre launch and now. It’s worth consideration. -
Zooko’s latest argument (the straw man) was UDAs /ZBTC Cannibalize zcash by making a certain type of whale move from ZEC to ZBTC.
This doesn’t seem to hold up to any critical evaluation.Even if such whales exist, this misses that those whales will move anyway from ZEC the moment some other chain offers private wrapped assets. And it also misses balajis’s point that wanting a native safe private store of value asset (e.g., zec) is different from wanting a wrapped verison of BTC with redemption risk. Meaning zooko’s whale isn’t the whale we were looking for. We don’t want someone who wants zbtc but settled for zec, we want someone who needs a natively private store of value.
-
There was also a fairness argument that somehow letting UDA users get chain space for less is unfair.
IMHO this can also be dismissed outright. First, as I pointed out earlier , UDAs provide increased privacy for ZEC holders. So it has value and in fact gets a lot of things dangerously backward. But more fundamentally, the premise is flawed. The only thing you pay to access Zcash’s chain is fees. And the proof of this is ZEC pages who’s users only need to pay fees to use it but consume zcash block space and security. We wouldn’t say zec pages success is unfair to Zcash holders. In fact, it makes the ecosystem better.
Are there any others?
