Ethereum devs expect 10x lower rollup costs as Dencun upgrade hits testnets

The Ethereum ecosystem is edging closer to significantly lower gas fees and faster transaction speeds for layer-2 rollups as the Dencun upgrade hits the network’s three testnets in early 2024.

The Dencun network upgrade was activated on the Goerli testnet on Jan. 17 and introduced several Ethereum Improvement Proposals (EIPs). Of particular interest is EIP-4844, which enables proto-danksharding, a highly anticipated improvement touted to reduce L2 transaction fees.

As Cointelegraph reported, the deployment of Dencun to Goerli suffered a four-hour delay caused by a bug that prevented the testnet from finalizing the upgrade. Speaking to Cointelegraph, Nebojsa Urosevic, co-founder of Ethereum development platform Tenderly, unpacked the details of the bug.

“The network could not sync with nodes because of a bug in Prysm, Ethereum’s proof-of-stake client," Urosevic said.

The Tenderly co-founder, who is also the senior vice president of its engineering team, noted that client synchronization delays are common, which allowed for the bug to be identified and rectified quickly:

“It’s one of the reasons why there are multiple clients and why testnets exist.”

Ethereum Foundation protocol lead Tim Beiko also shared a debrief from the latest All Core Developers Execution Call on Jan. 18, which outlined the historical root issue. Historical roots are a legacy mechanism that Ethereum’s Beacon Chain uses to manage the computational load of the blockchain’s state.

As Beiko sums up, the bug was related to Ethereum’s proof-of-stake client Prysm setting the historical roots value to 0, which prevented the Goerli testnet from finalizing the Dencun upgrade.

Dencun roadmap

As the official Ethereum blog outlines, Dencun incorporates nine different EIPs. Urosevic highlighted proto-danksharding and blob transactions as the most anticipated of the EIPs:

“Proto-danksharding is a major step toward improved Ethereum scalability, thanks to the use of blob-carrying transactions instead of calldata.”
Urosevic explains that data blobs will improve storage efficiency by making transaction data temporarily available in a compressed format. He adds that they are more cost-effective than calldata, with a potential cost reduction of 80%–90%.

Following the successful implementation on Goerli, the Sepolia and Holesky testnets are next in line to undergo the Dencun upgrade. Urosevic notes that successful deployment on all three testnets is required before plans are made to upgrade Ethereum’s mainnet.

Dencun’s storage improvements

Ethereum sidechain Gnosis’ infrastructure director Philippe Schommers highlights that Dencun will provide more block space and lower costs to L2s, while data that was previously stored indefinitely on-chain will be discarded after two weeks:

“This is scalability in a way that is compatible with our endgame without sacrificing decentralization.”
Urosevic echoes these sentiments, citing storage improvements as one of the major impacts of the Dencun upgrade.

“L2 networks will be able to store data on L1 more efficiently. Blobs will be deleted approximately every two weeks, which is enough for L2s to manage, retrieve and verify the data. This makes blobs cheaper than typical transaction calldata, which is stored indefinitely,” Urosevic explains.

The result sees Dencun deliver lower gas fees and faster transaction fees, which stands to open opportunities for “new, more complex applications on L2 solutions”:

“Dencun will probably lower rollup transaction costs by up to 10 times, depending on blob space demand.”

Rollups stand to be the biggest beneficiaries of the new upgrade, with their economic viability and scalability enhanced by reduced operational costs.

Anurag Arjun, a co-founder of data availability blockchain Avail, adds that the significant growth in demand for block space from rollups in 2023 suggests an expected increase in the demand for block space for data availability from L2s moving forward:

“Proto-danksharding will provide some relief, but it’s clear that rollups need a whole lot more block space for data availability, and we need to be thinking about how we can achieve this in a way that still prioritizes decentralization, scalability and security,” Arjun tells Cointelegraph.

While the systematic upgrades of the Ethereum network work toward lower fees and faster transactions, protocols like Avail could help address the block space demands of rollups in the interim.

Arjun notes that recent benchmarks of Avail’s zero-knowledge Ethereum Virtual Machine Validium reduce transaction fees by 90% by posting transaction data to Avail instead of Ethereum.

“It still settles to Ethereum and provides data availability guarantees that are decentralized and secure. This is becoming quite an attractive option for blockchains looking to move into the Ethereum ecosystem.”

Urosevic describes the end game of the Dencun upgrade on the Ethereum mainnet, commenting that its implementation will be the first time scalability issues are addressed directly on the mainnet. “Multiple EIPs will bring greater storage efficiency, lower gas fees and an overall better experience for developers while making rollups even more cost-efficient,” Urosevic said.

The Great Onboarding: US Government Anchors Global Economy into Web3 via Pyth Network

For years, the crypto world speculated that the next major cycle would be driven by institutional adoption, with Wall Street finally legitimizing Bitcoin through vehicles like ETFs. While that prediction has indeed materialized, a recent development signifies a far more profound integration of Web3 into the global economic fabric, moving beyond mere financial products to the very infrastructure of data itself. The U.S. government has taken a monumental step, cementing Web3's role as a foundational layer for modern data distribution. This door, once opened, is poised to remain so indefinitely.

The U.S. Department of Commerce has officially partnered with leading blockchain oracle providers, Pyth Network and Chainlink, to distribute critical official economic data directly on-chain. This initiative marks a historic shift, bringing immutable, transparent, and auditable data from the federal government itself onto decentralized networks. This is not just a technological upgrade; it's a strategic move to enhance data accuracy, transparency, and accessibility for a global audience.

Specifically, Pyth Network has been selected to publish Gross Domestic Product (GDP) data, starting with quarterly releases going back five years, with plans to expand to a broader range of economic datasets. Chainlink, the other key partner, will provide data feeds from the Bureau of Economic Analysis (BEA), including Real Gross Domestic Product (GDP) and the Personal Consumption Expenditures (PCE) Price Index. This crucial economic information will be made available across a multitude of blockchain networks, including major ecosystems like Ethereum, Avalanche, Base, Bitcoin, Solana, Tron, Stellar, Arbitrum One, Polygon PoS, and Optimism.

This development is closer to science fiction than traditional finance. The same oracle network, Pyth, that secures data for over 350 decentralized applications (dApps) across more than 50 blockchains, processing over $2.5 trillion in total trading volume through its oracles, is now the system of record for the United States' core economic indicators. Pyth's extensive infrastructure, spanning over 107 blockchains and supporting more than 600 applications, positions it as a trusted source for on-chain data. This is not about speculative assets; it's about leveraging proven, robust technology for critical public services.

The significance of this collaboration cannot be overstated. By bringing official statistics on-chain, the U.S. government is embracing cryptographic verifiability and immutable publication, setting a new precedent for how governments interact with decentralized technology. This initiative aligns with broader transparency goals and is supported by Secretary of Commerce Howard Lutnick, positioning the U.S. as a world leader in finance and blockchain innovation. The decision by a federal entity to trust decentralized oracles with sensitive economic data underscores the growing institutional confidence in these networks.

This is the cycle of the great onboarding. The distinction between "Web2" and "Web3" is rapidly becoming obsolete. When government data, institutional flows, and grassroots builders all operate on the same decentralized rails, we are simply talking about the internet—a new iteration, yes, but the internet nonetheless: an immutable internet where data is not only published but also verified and distributed in real-time.

Pyth Network stands as tangible proof that this technology serves a vital purpose. It demonstrates that the industry has moved beyond abstract "crypto tech" to offering solutions that address real-world needs and are now actively sought after and understood by traditional entities. Most importantly, it proves that Web3 is no longer seeking permission; it has received the highest validation a system can receive—the trust of governments and markets alike.

This is not merely a fleeting trend; it's a crowning moment in global adoption. The U.S. government has just validated what many in the Web3 space have been building towards for years: that Web3 is not a sideshow, but a foundational layer for the future. The current cycle will be remembered as the moment the world definitively crossed this threshold, marking the last great opportunity to truly say, "we were early."

US Dept of Commerce to publish GDP data on blockchain

On Tuesday during a televised White House cabinet meeting, Commerce Secretary Howard Lutnick announced the intention to publish GDP statistics on blockchains. Today Chainlink and Pyth said they were selected as the decentralized oracles to distribute the data.

Lutnick said, “The Department of Commerce is going to start issuing its statistics on the blockchain because you are the crypto President. And we are going to put out GDP on the blockchain, so people can use the blockchain for data distribution. And then we’re going to make that available to the entire government. So, all of you can do it. We’re just ironing out all the details.”

The data includes Real GDP and the PCE Price Index, which reflects changes in the prices of domestic consumer goods and services. The statistics are released monthly and quarterly. The biggest initial use will likely be by on-chain prediction markets. But as more data comes online, such as broader inflation data or interest rates from the Federal Reserve, it could be used to automate various financial instruments. Apart from using the data in smart contracts, sources of tamperproof data 👉will become increasingly important for generative AI.

While it would be possible to procure the data from third parties, it is always ideal to get it from the source to ensure its accuracy. Getting data directly from government sources makes it tamperproof, provided the original data feed has not been manipulated before it reaches the oracle.
