On Wednesday morning, the Ethereum blockchain accomplished an improve referred to as Dencun, the largest change to the community’s code in over a 12 months. The improve is a crucial step to assist the world’s second most beneficial blockchain overcome its scaling challenges, and cut back its notorious fuel charges. However what precisely is Dencun and the way does it work? Our plain English explainer tells all you’ll want to know.
What’s the Dencun improve?
Dencun describes two upgrades that befell on the identical time on Ethereum. The title combines the “Cancun” improve of the execution layer and the “Deneb” improve on the consensus layer. The latter refers to how community customers agree on the state of the blockchain, whereas the previous refers to how transactions are processed.
In technical phrases, the improve is the results of a brand new Ethereum Enchancment Proposal (EIP) referred to as “proto-danksharding,” or EIP-4844, which improves the blockchain’s propensity to deal with knowledge from secondary networks.

Why did Dencun come about within the first place?
The improve will decrease fuel charges for the rising variety of networks constructed on high of Ethereum which can be generally known as Layer 2 (L2) or “rollups.” That is necessary since fuel charges have traditionally soared each time there’s a surge of exercise on the blockchain, making it unviable to make use of at a big scale. Roll-ups assist deal with this by processing transactions individually, after which stamping them to the primary Ethereum blockchain in batches.
Whereas roll-ups have already made Ethereum extra environment friendly, one concern that’s that, post-compression, nodes processing transactions maintain on to L2 knowledge infinitely, requiring a larger quantity of {hardware} as time goes on. This has meant that over 90% of the charges on rollups are used for this knowledge storage.
The improve means L2 knowledge can be added to the bottom Ethereum community by way of fleeting, extra environment friendly “blobs” reasonably than knowledge held indefinitely. As a substitute, “blob knowledge” can be saved for 18 days.
What about the primary Ethereum community?
The general impact needs to be decrease prices, however customers on the primary blockchain (L1) gained’t take pleasure in these decrease charges till a minimum of 2026-27, says Pitchbook’s crypto analyst Robert Le, till there’s “full danksharding,” referring to a rollup scaling technique which offers further storage for elevated transactional capability.
“Over the subsequent couple of years, you’ll see much less and fewer particular person customers, whether or not retail or companies, transact straight on Ethereum. Extra will transfer to L2s and the one ones transacting on Ethereum would be the rollups,” he mentioned.
EIP-4844 marks the start of the “Surge” section for Ethereum, outlined by the community’s co-founder Vitalik Buterin in December. The intention of this section is to succeed in 100,000 transactions per second.
How a lot will Dencun decrease charges?
Fuel charges had risen to a mean of 98 gwei (a denomination value one-billionth of an Ether, the native cryptocurrency for the Ethereum blockchain) the week earlier than the improve, a stage not seen since early Could 2023, in accordance with Ethercan knowledge. A swap would value customers $87.45 in fuel charges on common, whereas nonfungible token (NFT) gross sales common $147 in fuel.
After the Ethereum Dencun improve this week, EIP-4844 will cut back L2 fuel charges. Based on IntoTheBlock statistics, for a DEX swap, the fuel payment for Aribitrum can be diminished from $2.02 to $0.4, Optimism can be diminished from $1.42 to $0.28, Base can be diminished from $0.58 to… pic.twitter.com/0x6jGDYF5z

L2 charges will drop by an element of 10 after the improve. Swapping tokens on decentralized exchanges, which at the moment prices $1-2, ought to fall to round 10-20 cents, and will even go as little as a fraction of a cent.
What does Dencun imply for the value of Ether?
Ether (ETH) has climbed over 150% since October. Final week it broke $4,000, for the second time ever, the place it has hovered since, indicating it may quickly go its all-time-high of $4,878.26, reached in November 2021.
The worth surge is a part of a broader bull crypto bull market spurred by the approval of Bitcoin ETFs in January, and optimism that regulators will approve Ethereum ETFs too this 12 months. However specialists informed Fortune they foresee the improve having a continued, optimistic impression on ETH’s value that may very well be extra important than ETFs, as traders guess on the community’s growth potential.
Will probably be an “absolute recreation changer” for the token, and is the “greater story proper now,” Matt Hougan, Bitwise’s CIO, informed Fortune.
“There are a billion functions you’ll be able to construct if transactions are beneath a penny you can’t construct if they vary from 10 to 50 cent,” mentioned Hougan. “As soon as we get them reliably free to folks, you will notice monetary functions, DeFi and NFT’s, however additionally, you will see non-financial functions. I feel we’re gonna see this huge explosion of mainstream makes use of,” he mentioned.
“We’re constructing a brand new kind of expertise, a brand new kind of platform. I feel that’s what ETH has going for it on the sentiment aspect, and why it’s doing so nicely,” Vance Spencer, founding father of Framework Ventures, added.
