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 vital step to assist the world’s second most beneficial blockchain overcome its scaling challenges, and cut back its notorious gasoline charges. However what precisely is Dencun and the way does it work? Our plain English explainer tells all it’s good to know.
What’s the Dencun improve?
Dencun describes two upgrades that befell on the similar time on Ethereum. The identify 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 gas fees for the rising variety of networks constructed on prime of Ethereum which can be referred to as Layer 2 (L2) or “rollups.” That is necessary since gasoline 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 tackle this by processing transactions individually, after which stamping them to the principle Ethereum blockchain in batches.
Whereas roll-ups have already made Ethereum extra environment friendly, one difficulty 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 shall be added to the bottom Ethereum community by way of fleeting, extra environment friendly “blobs” reasonably than knowledge held indefinitely. As a substitute, “blob data” shall be saved for 18 days.
What about the principle Ethereum community?
The general impact needs to be decrease prices, however customers on the principle blockchain (L1) gained’t take pleasure in these decrease charges till at the very least 2026-27, says Pitchbook’s crypto analyst Robert Le, till there may be “full danksharding,” referring to a rollup scaling technique which supplies additional storage for elevated transactional capability.
“Over the next couple of years, you’ll see less and less individual users, whether retail or businesses, transact directly on Ethereum. More will move to L2s and the only ones transacting on Ethereum will 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?
Gasoline charges had risen to a median 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 response to Ethercan knowledge. A swap would value customers $87.45 in gasoline charges on common, whereas nonfungible token (NFT) gross sales common $147 in gasoline.
After the Ethereum Dencun improve this week, EIP-4844 will cut back L2 gasoline charges. Based on IntoTheBlock statistics, for a DEX swap, the gasoline price for Aribitrum shall be diminished from $2.02 to $0.4, Optimism shall be diminished from $1.42 to $0.28, Base shall 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 presently 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 worth 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 consultants advised Fortune they foresee the improve having a continued, constructive affect on ETH’s worth that could possibly be extra vital than ETFs, as buyers guess on the community’s growth potential.
Will probably be an “absolute game changer” for the token, and is the “bigger story right now,” Matt Hougan, Bitwise’s CIO, advised Fortune.
“There are a billion applications you can build if transactions are below a penny that you can’t build if they range from 10 to 50 cent,” mentioned Hougan. “Once we get them reliably free to people, you will see financial applications, DeFi and NFT’s, but you will also see non-financial applications. I think we’re gonna see this massive explosion of mainstream uses,” he mentioned.
“We’re building a new type of technology, a new type of platform. I think that’s what ETH has going for it on the sentiment side, and why it’s doing so well,” Vance Spencer, founding father of Framework Ventures, added.
