The highly anticipated Ethereum Dencun upgrade has passed its final test. This will likely pave the way for the blockchain to launch on the main public network next month.

The upgrade was recently put through a full rehearsal on the Holesky test network, designed to mimic conditions on Ethereum’s live blockchain. In addition, the successful trial run suggests any remaining issues have been identified and addressed ahead of a mainnet rollout in early March.

  • Dencun will introduce “proto-danksharding,” allowing for the storage of large data sets through “blobs” to make transactions cheaper.
  • After testing on two other networks, Wednesday’s Holesky simulation was the final and most robust trial of the upgrade’s components.
  • Ethereum developers will meet Thursday to set an expected launch date, targeting late February or early March.

Ethereum Dencun Tested Across Multiple Networks

The Dencun upgrade bundles together several technical improvements for Ethereum that touch both the execution layer, where transactions occur, and the consensus layer, where blocks are built and validated.

Key among those changes is the concept of “proto-danksharding,” which introduces blobs as storage spaces for sizable data sets. In addition, this will greatly reduce demand on the blockchain’s base layer, lowering fees, especially for Layer 2 networks.

Developers have carefully tested Dencun using simulated environments like Holesky to root out any bugs. Holesky is the most advanced testing platform, using technology very close to Ethereum’s current mainnet infrastructure.

With Holesky’s run of Dencun now completed without issues, Ethereum developers are nearly ready to deploy the upgrade on the live public blockchain.

The team will meet on Thursday to finalize timing, but expectations point to activation in late February or early March.
