Ethereum Dencun Upgrade Timelines Shared For Sepolia and Holesky Testnets – Mainnet Next?
The highly anticipated Ethereum hard fork Dencun is gearing up for its testnet debut on Sepolia and Holesky in the upcoming weeks.
Confirming this development in a recent blog post, the Ethereum Protocol Support Team stated that the latest upgrade to the smart contract network is scheduled for January 30 and February 7.
The Dencun upgrade, a part of the Ethereum Improvement Proposal (EIP) series, will introduce the ‘proto-danksharding’ feature, which runs on data blobs. It is duly denoted with the EIP-7569 tag, and the ‘proto-danksharding’ feature is only one of the offerings.
Once they hit the public Ethereum blockchain, data blobs are expected to be more storage efficient and radically reduce layer-2 (L2) scaling solutions’ rollup costs and transaction fees.
Currently, the Dencun hard fork is being battle-tested on the Goerli testnet after making its official launch on January 17.
On January 30, it would migrate to the Sepolia testnet and make its final stand on Holesky on February 7. If the testing phase proceeds without significant issues, the Dencun upgrade is slated to transition to the Ethereum mainnet.
More testnet blobs on the way .oO
Dencun will activate on Sepolia Jan 30, and on Holesky Feb 7. If running a node on either network, now's the time to update it!
Assuming both of these go smoothly, mainnet is next ✅https://t.co/QbEUACix2S

Delving into the details, the Ethereum Protocol Support Team stated that the Sepolia testnet series for Dencun will activate at 22:51:12 UTC at the epoch height of 132608. The first epoch confirming its slot succession will kick in at 4243456.
On the other hand, Holesky’s launch is scheduled for 11:34:24 at the epoch height of 29696, with its
