As Ethereum developers prepare for the much-anticipated Dencun upgrade, the blockchain is set to witness one of its most significant code changes in over a year. Dencun, a combination of the project names Deneb and Cancun, encompasses two simultaneous upgrades on Ethereum’s consensus and execution layers. Set to initiate at 13:55 UTC (9:55 a.m. ET), this hard fork aims to introduce cheaper fees for auxiliary networks, known as layer-2 (L2) “rollups,” that operate on top of Ethereum.
Central to the Dencun upgrade is the implementation of Ethereum Improvement Proposal (EIP) called “proto-danksharding,” or EIP-4844. This proposal aims to enhance Ethereum’s ability to handle data from L2 networks by introducing a new method called “blobs” for storing transaction data. By leveraging blobs, L2 networks like Arbitrum, Optimism, and Polygon will experience significant benefits, enabling them to settle more data efficiently, resulting in reduced fees for end-users.
Dencun has been several years in the making, with the development team conducting thorough testing on three separate test networks (testnets). While some initial bugs were encountered during the first test on Goerli, they were promptly addressed, ensuring a smooth testing process thereafter.
To mark the official launch of Dencun, Ethereum enthusiasts and developers have organized watch parties. EthStaker and Nethermind, a prominent Ethereum infrastructure team, will host livestreams to celebrate this milestone.
Frequently Asked Questions:
Q: What is Dencun?
A: Dencun is Ethereum’s most significant upgrade since the April 2023 Shapella update. It introduces several code changes, with the highlight being the implementation of “proto-danksharding,” a method for storing transaction data using blobs.
Q: How will layer-2 networks benefit from Dencun?
A: Layer-2 networks like Arbitrum, Optimism, and Polygon will experience significant advantages from Dencun. They will be able to post data to Ethereum within dedicated blobspace, reducing costs and improving efficiency, resulting in lower fees for end-users.
Q: What is “proto-danksharding”?
A: Proto-danksharding is Ethereum’s first attempt at sharding, a technique that divides the blockchain into mini-shards to process more transactions at a lower cost. While a fully-formed version of sharding is still being developed, proto-danksharding addresses Ethereum’s high gas fees in the short-term by reducing fees for layer-2 networks.
Q: Will proto-danksharding benefit data availability (DA) layers?
A: Yes, proto-danksharding will also benefit data availability layers such as Celestia, EigenDA, and Avail. These layers help store large amounts of data, frequently used by layer-2 networks to store transaction data. Proto-danksharding will make downloading DA data more cost-effective.
Q: What is next for Ethereum after Dencun?
A: Following the Dencun upgrade, Ethereum developers will shift their focus to the Electra + Prague (Petra) upgrade. While the exact details of this upgrade are yet to be finalized, one potential addition is “Verkle Trees,” which will enable nodes to store large amounts of data.
With the Dencun upgrade, Ethereum is paving the way for enhanced scalability and cheaper fees, enabling developers across the ecosystem to collaborate more seamlessly. This shift towards permissionless collaboration holds the promise of providing user experiences that rival those of centralized platforms. As the blockchain ecosystem evolves, Ethereum continues to prioritize innovation and improvement, keeping developers and users excited about its future possibilities.
