The conversations round Ethereum (ETH) and its knowledge storage for optimum performance have made it to crypto X with Polygon co-founder Mihailo Bjelic and Vitalik Buterin debating the probabilities. The dialog began with Bjelic posting a query during which he sought to know if builders are certain it’s proper to modify Ethereum to Verkle bushes, provided that its zk-fication is kind of seemingly.
Wading into the dialog, Vitalik Buterin stated, “ZK-ifying keccak merkle patricia bushes with worst case 300 MB witness sizes is a non-starter.” Notably, the Merkle Patricia bushes type the present or major knowledge construction that’s getting used throughout the Ethereum blockchain. This knowledge storage construction has its limits, and the plan quickly is to interchange it with Verkle bushes with shorter proofs and elevated bandwidth.
To Bjelic, the present construction, in line with the capability of Polygon zkEVM, can deal with the 300 MB benchmark famous by Buterin. The Polygon founder famous that the protocol may even do that simply with a complete block time of 12 seconds. He, nonetheless, acknowledged that for this to work, it will want roughly 10 server-class CPUs.
Buterin’s lasting resolution
Per the presentation made by Vitalik Buterin, Merkle bushes weren’t designed to be suitable with ZK expertise. Nevertheless, he famous that Verkle bushes with a vector factor are designed to assist obtain this objective in the end.
ZK-ifying keccak merkle patricia bushes with worst case 300 MB witness sizes is a non-starter.
The verkle tree spec is designed to be zk pleasant (eg. alternative of curve, utilizing pedersen because the hash)
So switching to verkle helps with ZKing the L1.

Per the design of your entire Ethereum structure, ZK protocols are principally embodied as Layer-2 scaling options. Whereas these L2s have higher throughput, scalability, gasoline charges and knowledge storage, Ethereum nonetheless battles to maintain up with scaling up amid the demand.
To transform Ethereum to a ZK-tech suitable community, Vitalik Buterin highlighted how this will solely be achievable utilizing Verkle bushes. If that is achieved, in the end, Ethereum may additionally profit from the impacts of the Dencun improve in the long run.
