Polygon developers told how the Ethereum update of Dencun will reduce commissions
The Polygon platform uses two scaling methods: a PoS sidechain of the same name and a Rollups network based on zero-knowledge proof technology (ZKP) called Polygon zkEVM.
The upcoming Dencun update of the main Ethereum network will mitigate the problem of the high cost of data availability for Rollups networks. This opinion was expressed by the technical head of Polygon zkEVM, Jordi Bailina, reports The Block.
The activation of the hard fork in the mainnet is expected on March 13. One of the main components of the update is the EIP-4844. It includes a Proto-Danksharding option designed for scaling. It is assumed that the solution will reduce commissions in second-tier networks.
Bailina believes that the implementation of EIP-4844 will "triple the total capacity of Ethereum data." This will seriously help rollups like zkEVM, Linea, Scroll and zkSync reduce gas costs.
According to him, the amount of savings will depend on a number of factors, but data compression costs are expected to decrease by 10-50 times.
According to L2 Fees, the commissions in Polygon zkEVM are noticeably higher than those of competing rollups. For example, transferring ETH via the protocol will cost $0.88, whereas the cost of such a transaction on zkSync Era will be $0.12.
Bailina also noted that the implementation of Dencun is easier for L2 solutions based on Optimistic Rollups, such as Optimism and Arbitrum. ZKP project teams need to make some technical preparations for the upgrade. Thus, as part of these efforts, the developers of Polygon zkEVM implemented precompiled smart contracts for all cryptocurrency pairs during the February Etrog hard fork.
