Ethereum’s Dencun Upgrade Unleashes Game-Changing ‘Proto-Danksharding’ on Goerli Testnet (crypto-news-flash)


  • The Dencun upgrade went live today on the Goerli testnet in an effort to cut down storage costs for Ethereum nodes and Layer 2 networks through proto-danksharding.
  • The upgrade encountered challenges, including a potential chain split as the Ethereum clients were not able to sync easily, an issue that the developers are working on and expect to solve soon.

The much-anticipated Dencun upgrade went live earlier today on the Goerli testnet as the first step towards making the Ethereum network cheaper for users.

Dencun is the most significant Ethereum upgrade since the Shapella upgrade in March 2023, which allowed users to finally withdraw the Ether they staked as the network transitioned to proof-of-stake.

However, the process faced significant challenges, the first being low node participation. As Tim Beiko revealed on X, the low participation was expected. Beiko, a core developer at Ethereum, noted that this was due to the operators failing to upgrade a piece of software required for the process or a software bug.

Beiko and the other core developers are working on this hitch and expect to resolve it soon.

“And it seems like we have a chain split! Client teams are looking into it, but it’s likely to take a while to pin down + fix the issues. Keep an eye out for updates!” Beiko said in an update.

Dencun took several hours to achieve finality, which refers to the confirmation of a transaction on the blockchain, rendering it irreversible and immutable. As one developer revealed, they patched in a fix, after which “the validators returned online, and the chain started finalizing again. The MEV circuit breaker automatically disables, and mev-blocks have started flowing through as well.”

The goerli fork finalized! 😀

Yay client diversity!

Dencun was activated on Goerli, an open-source and community-based proof-of-authority cross-client testnet. It allows developers to give their upgrades and features an initial run before they are deployed for the public on the main chain, ensuring developers can make any required improvements in a safe environment.

Dencun Ushers in a New Era for Ethereum

Dencun is a significant milestone for the Ethereum ecosystem. The most prominent feature is proto-danksharding, a mechanism that will expand the capacity of the nodes to store data on the network.

In a livestream following the upgrade, Beiko described the significance of Dencun and the EIP 4844, saying it will be a game-changer for Layer 2s.

“It provides layer 2s a way to store data on Ethereum that’s ephemeral,” he noted, revealing the team has been working on the upgrade for two years. Currently, most of the fees charged by Layer 2s go to posting data back on the Ethereum Layer 1 chain.

With EIP 4844, we’re basically introducing data storage on Ethereum, which, after a couple of weeks, gets pruned from the network, and so we’re able to price it much cheaper than we price the permanent storage that L2s use.
