Don’t get me fallacious, each are nice applied sciences and each are helpful in lots of conditions. Nevertheless, the Ethereum roadmap modified solely and is now relying totally on L2s for scalability, and appears like most L2s are funding ZK growth far more than optimistic growth.
This isn’t to say that optimistic tech is unhealthy, it’s simply that zero-knowledge has a slight edge plus has much more room for development.
Zero-knowledge proofs are usually quicker than optimistic proofing, in addition they cheaper and are WAY extra personal.
The best way that ZK proofs work is thru offering solely the required primary info wanted for the transaction to be validated with out having to reveal any personal or delicate info relating to the identification of the consumer.
That is merely not doable with optimistic proofs. It is just a characteristic that zero-knowledge proofs can execute which explains why L2s are so centered on ZK.
Then there’s the truth that ZK tech has extra room for development in comparison with optimistic tech.
One may arguably say that optimistic tech has neared its peak in growth whereas zero-knowledge growth remains to be getting began.
We’re presently seeing a battle between SNARK and STARK applied sciences with each offering favorable options relying on the scenario.
Some L2s (particularly Polygon) make the most of each.
Actually, one of many essential causes I like Polygon a lot is that they not solely make the most of SNARKs and STARKs, however in addition they make the most of optimistic tech together with ZK tech
-
Miden (zkSTARK)
-
Zero (recursive SNARK)
-
Hermez (zkSNARK)
-
Avail (Validium)
-
Dusk (Optimistic)
With all of that being stated, I nonetheless assume that optimistic tech will at all times be wanted on Ethereum and in received’t be phased out.
There’ll at all times be conditions the place it is smart to make use of optimistic tech.
I simply assume that the principle focus will quickly begin shifting towards ZK as we see greater than extra L2s compete for higher and quicker growth.
Eitherway, the brand new Ethereum roadmap will give L2s an enormous enhance in throughput so it actually doesn’t matter in relation to scalability. All I actually care about is privateness, which ZK positively takes the sting for.
