Ethereum has officially entered a new era. On March 13, 2024, the highly anticipated Dencun upgrade went live on the Ethereum mainnet, marking the largest single hard fork in the network’s history in terms of improvements deployed. The upgrade, which incorporates nine Ethereum Improvement Proposals, is anchored by EIP-4844 — a feature widely known as “proto-danksharding” that introduces a revolutionary data storage mechanism called “blobs.”
TL;DR
- Ethereum’s Dencun upgrade went live on March 13, 2024, introducing proto-danksharding via EIP-4844
- The upgrade incorporates 9 EIPs — the largest single hard fork by number of improvements
- Layer 2 rollups can now use “blobs” for cheaper temporary data storage instead of expensive permanent storage
- ETH surged past $4,000 ahead of the upgrade, reaching its highest level in nearly two years
- Nearly $200 million worth of ETH was burned in the week leading up to Dencun
What Dencun Actually Changes
The core innovation behind Dencun lies in how Ethereum handles data for Layer 2 rollups. Previously, all data on Ethereum had to be stored permanently — an expensive proposition that drove up fees for everyone, especially users of Layer 2 networks like Arbitrum, Optimism, and Base. EIP-4844 changes this by introducing “blobs” — a new temporary data storage mechanism that is just as secure but significantly cheaper.
According to a report by Fidelity Digital Assets, Dencun represents the first step toward enabling Ethereum’s full roll-up roadmap. The network can now function more like an efficient database for Layer 2 blockchains, storing data in a way that passes massive cost savings down to end users. The result? Near-zero transaction fees on Layer 2 networks.
ETH Price Surges Past $4,000
The excitement surrounding Dencun helped propel Ether to $4,000 on March 12, its highest price point since early 2022. ETH has rallied more than 80% from its January 23 low of $2,165, with 60% of those gains coming in just the past month alone. As of March 14, ETH was trading around $3,883 according to CoinMarketCap data, with a market capitalization exceeding $466 billion.
On-chain data revealed that approximately $200 million worth of ETH was burned over the week leading up to the upgrade, reducing circulating supply and adding upward pressure on the price. The combination of Dencun hype, supply reduction through burning, and broader crypto market bullish sentiment created a powerful tailwind for Ether.
Implications for the Broader Ecosystem
While Dencun generated significant excitement among Ethereum’s technical community, it notably produced less mainstream buzz compared to the 2022 Merge, which transformed Ethereum from proof-of-work to proof-of-stake. However, industry experts have described Dencun as equally significant in terms of its long-term impact on the network’s scalability and usability.
The upgrade brings the necessary infrastructure to accommodate millions of additional users on Layer 2 blockchains. By dramatically reducing transaction costs, Dencun positions Ethereum as a more accessible platform for developers and users alike, potentially driving mainstream adoption of decentralized applications that were previously hindered by high gas fees.
Grayscale Pushes for ETH ETF
Adding to Ethereum’s momentum, Grayscale submitted a revised application to convert its ETH trust into a spot Ethereum ETF around the same time as the Dencun launch. Following the successful approval of 11 Bitcoin spot ETFs in January, the crypto industry has been watching closely for signs that the SEC might greenlight an Ethereum equivalent. An ETH ETF approval would open the door for significant institutional capital to flow into Ether, mirroring the effect Bitcoin ETFs had on BTC earlier in 2024.
Why This Matters
Dencun is not just a technical upgrade — it is a fundamental shift in Ethereum’s value proposition. By slashing Layer 2 fees to near-zero, it removes one of the biggest barriers to mainstream adoption of decentralized applications. Combined with ETH’s strong price performance, ongoing supply reduction through burning, and the prospect of an ETH ETF on the horizon, Ethereum is positioning itself for what could be a transformative year. The network’s ability to attract both developers and institutional investors while simultaneously improving its core infrastructure makes it a compelling case study in how blockchain platforms evolve to meet growing demand.

blobs are the most elegant solution ETH has shipped since 1559. starknet fees going from $1.35 to under $0.02 is wild
from $1.35 to under $0.02 on starknet. the fee reduction was 98% overnight. anyone who says L2s dont work wasnt paying attention to this
blob_maxi_ blobs since 1559 is the right comparison. both upgrades fundamentally changed ETH economics. 1559 changed monetary policy, 4844 changed scaling economics. equally important
shard_keeper_ comparing 4844 to 1559 is apt. both changed the economic model of ETH itself. 1559 changed fee distribution, 4844 changed the data layer
blobs are most elegant solution eth has shipped since 1559. starknet fees going from 1.35 to under 0.02 is wild
finally. paying $0.50 to move $10 on arbitrum was killing any chance of adoption outside of degens
my non-crypto friends actually tried using base after dencum. the fee drop is what makes it usable for people who arent traders
base after dencun was the first time i could actually recommend an L2 to non-crypto friends without apologizing for the fees
same experience. recommended base to my sister and she actually completed a tx without asking what gas meant
from 1.35 to under 0.02 on starknet. fee reduction was 98% overnight. anyone who says l2s dont work wasnt paying attention
base after dencun was first time i could actually recommend l2 to non-crypto friends without apologizing for fees
went from apologizing for ETH L2 fees to paying less than a venmo transaction. the $0.50 days feel ancient now
starknet going from 1.35 to under 0.02 overnight is the single best L2 advertisement ethereum could ask for
the $200M in ETH burned the week before Dencun is the most ETH-maxi thing ever. paying record fees to ship an upgrade that makes fees 98 percent cheaper. poetic
fee_reference paying record fees to ship an upgrade that makes fees 98% cheaper is peak ethereum. the irony was not lost on anyone
Nearly $200 million in ETH burned the week before Dencun. People were paying to upgrade the network while celebrating the upgrade itself
the irony of paying high fees to deploy the code that makes fees cheap. ETH was burning itself to make itself cheaper
buff_validators_ its not irony, its the cost of coordination. thousands of validators had to process those transactions to reach consensus on the upgrade. the fees funded the launch
9 EIPs in one fork and 4844 got all the attention. the other 8 had meaningful improvements too but blobs stole the spotlight
