ChainCatcher message, Ethereum protocol developer and Prysm maintainer Terence posted on the X platform that the Ethereum core developers meeting (AllCoreDevs) has reached a preliminary consensus to increase the blob target/max from 3/6 to 6/9, with specific implementation requiring further testing and results from the development network.

ChainCatcher message, Vitalik stated on Warpcast that the Blob has quietly "entered price discovery," with recent total fees averaging about 10 ETH per day.

ChainCatcher news, the airdrop frenzy of the Ethereum L2 network Scroll has pushed the Ethereum blob fees up to $4.52, marking the third significant increase in blob fees since the Ethereum Dencun upgrade in March. Crypto data analyst Hildobby posted on X that the rise in blob fees is related to Scroll opening airdrop claims.According to data from Dune Analytics, on October 22, blob fees reached a four-month high of $4.52.The significant increase in blob fees has only occurred twice before: once during the surge of L2 activity in July, and once during the launch of Blobscriptions on March 27, a protocol that allows users to directly inscribe data onto blobs.Analysis indicates that the increase in blob fees is a double-edged sword for Ethereum. More expensive blobs will lead to higher blob gas payments to the network; however, they will also raise the costs of executing transactions and transfers on Ethereum L2.

ChainCatcher news, Galaxy's Vice President of Research Christine Kim summarized the main points of the 144th Ethereum Core Developers Consensus Meeting (ACDC #144):Developers agreed to include a new code change EIP 7742 in Pectra, which allows the beacon chain to dynamically set the network's target and maximum blob gas limits. The inclusion of EIP 7742 indicates that developers may also increase the target and maximum blob gas limits in Pectra. However, some developers raised concerns during the call that incorporating additional EIPs (especially EIP 7742) would delay the activation of other Pectra code changes on the mainnet. Developers also discussed the testing progress of Pectra and PeerDAS development.L2 rollup Base developer Francis Li introduced the urgency and fundamental principles of increasing blob capacity in Pectra. Li suggested increasing the blob gas target to 5 and the maximum to 8, along with additional work at the network layer, such as implementing engine_getBlobsV1. Busa pointed out that the increase in blob capacity should be combined with the deployment of EIP 7742, which introduces a mechanism to dynamically set blob gas targets and maximum limits through CL. Busa stated that the current mechanism for setting these parameters is difficult to change, and introducing EIP 7742 would ensure that developers can easily adjust these settings in the future, such as upgrades like PeerDAS. However, Busa also noted that EIP 7742 requires additional work from the EL and CL client teams for deployment and could delay Pectra's timeline by 1 to 2 months. He urged developers to consider starting the work on deploying EIP 7742 as soon as possible to avoid unnecessary delays in the Pectra upgrade.

ChainCatcher news, according to Cointelegraph, Ethereum co-founder Vitalik Buterin urged for an increase in the "number of blobs" introduced during the Dencun upgrade to further expand the network and enable Layer 2 protocols to increase capacity.In a discussion following the latest developer call, Vitalik revealed that the current usage rate of blob space is nearing 75%, and there is a need to increase the number of blobs through the EIP-7623 proposal. He stated, "I think the entire ecosystem is ignoring the fact that it is uncomfortably close to the limit."It is reported that blob space is a dedicated data storage area introduced by EIP-4844 (also known as proto-danksharding) aimed at improving the scalability of the network. The number of blobs refers to the number of blobs that can be included in each Ethereum block. The current goal is to have 3 blobs per block, with a maximum of 6, but Vitalik is now advocating for an increase to 4 blobs per block, with a maximum of 8, so that each block can store more data.

ChainCatcher news, Galaxy's Vice President of Research Christine Kim summarized the 197th Ethereum Core Developers Execution (ACDE) conference, discussing and coordinating changes to the Ethereum Execution Layer (EL). Developers agreed to advance the Pectra upgrade within a limited scope, currently only including 8 Ethereum Improvement Proposals (EIPs) on Devnet 3. They also agreed that a set of 4 EIPs related to the Ethereum blob fee market might be included in Pectra during the upgrade planning process, with Vitalik expressing support for increasing blob capacity in Pectra, while other developers voiced opposition, and no conclusion has been reached yet.Other blob-related EIPs include EIP 7762 (increase MIN_BASE_FEE_PER_BLOB_GAS), EIP 7623 (increase calldata costs), and EIP 7742 (separate blob counting between CL and EL).Beiko confirmed that the next upgrade after Pectra will indeed be named Fusaka, which will include PeerDAS and EOF. Fusaka may also incorporate additional EIPs, provided that further progress can be made on the implementation of these two EIPs. Finally, Beiko stated that a new EIP for EL upgrades will be opened after Osaka, named "Amsterdam," and the EIP originally considered for inclusion in Osaka, namely Verkle, will be carried over to the new Amsterdam EIP.

ChainCatcher news, Ethereum co-founder Vitalik Buterin recently responded to concerns raised by Ethereum core developer Péter Szilágyi regarding network decentralization and validation mechanisms.In response to how validators can obtain 32MB of blob transaction data every 12 seconds, Buterin proposed two possible strategies: each validator is responsible for building only 1/16 of the block, or validators only perform DAS checks without needing to fully download the data.Regarding the issue of Verkle tree design not deleting storage slots, Buterin stated that the impact of deleting storage slots is currently quite small. He denied claims about abandoning the transaction pool, emphasizing that this is an outdated idea that does not align with the current direction of Ethereum research.Buterin acknowledged that validation does not require an execution layer (EL), but stressed that this does not mean making it difficult for most people to run an EL. He pointed out that using SNARKs technology could enable more users to achieve full validation.Buterin emphasized that the key goal for validators is to avoid power concentration, especially in terms of consensus rule validation, fork choice, and transaction inclusion. He believes that during periods of only witnessing, there is no need to re-execute the EVM cycle.

ChainCatcher message, regarding Vitalik's response to "Ethereum is becoming increasingly decentralized in validation, but centralized control," a community user mentioned, "Sending 32MB of data to 4 nodes requires 1Gbit of upstream bandwidth, and if the network needs 4 hops, it requires 4Gbits of bandwidth. Additionally, considering data propagation, the upstream bandwidth requirement could double, reaching 2.5GBit/s." This was not directly addressed.Vitalik Buterin stated that we do not need a single participant to broadcast all blobs. These blobs are already in the mempool, and there are many distributed broadcasting options. There are still quite a few steps to achieve the complete DAS for the 16 MB goal, and there are no plans to persist until a satisfactory solution is found.

According to ChainCatcher news, RISC Zero, a zero-knowledge proof software developer, is collaborating with Celestia to build a zkVM-based cross-chain bridge called "Blobstream Zero." Blobstream Zero will enable Rollups and applications to ZK prove and verify the data availability (DA) of Celestia across any chain by connecting Celestia's modular data availability layer with Ethereum, Optimism, Bitcoin, Solana, and more.Blobstream Zero will conduct on-chain verification across all major chains, starting with Ethereum and gradually expanding to Optimism, Arbitrum, Solana, and Bitcoin, with more features to be launched in the coming months. Blobstream Zero will also allow applications to combine their execution ZK proofs with recursive DA light client proofs and inclusion proofs to optimize existing and new use cases.

ChainCatcher news, EigenDA indicates that it is working towards achieving permissionless payments for blob throughput on EigenDA, which will be released later this year. When this system is launched, EigenDA will still provide reserved bandwidth for high throughput use cases at a fixed rate.EigenDA is currently generating a sustained synthetic load of 0.6 MB/s and has already conducted load tests on the mainnet with peak throughput of up to 10 MB/s. In comparison, Ethereum's 4844 blob throughput is 0.032 MB/s, while Celestia's mainnet is at 0.16 MB/s.

ChainCatcher news, the modular blockchain network Celestia announced on social media that Blobstream has launched on the Ethereum mainnet. Developed by Succinct Labs, Blobstream streams the commitment of Celestia's data root to on-chain Ethereum light clients, providing permissionless high-throughput data availability (DA) for Ethereum Layer 2 (L2), ensuring security through cryptoeconomic guarantees rather than reputation or hidden trust assumptions. Blobstream is also available on celenium.io, allowing anyone to track the on-chain commitments of Celestia's data root.It is reported that Blobstream was previously known as the Quantum Gravity Bridge (QGB), serving as a bridge between Celestia and Ethereum (or its EVM L1 chain) to facilitate the transfer of data and assets between the two networks.

ChainCatcher news, the decentralized indexing protocol Hemera announced on X that Hemera has partnered with 0G Labs to launch BlobArchive, providing permanent data availability for L2. BlobArchive can store all data blobs created after the launch of EIP-4844 on Ethereum. Taiko is the first customer to retrieve blob data using this solution after EIP-4844.BlobArchive leverages cloud hosting and decentralized storage to create a decentralized solution with performance guarantees, featuring high performance, permanent storage, and easy verification.

ChainCatcher message, Blast indicates on X that it will support the upgrade of blobs at 2 PM Pacific Time on May 27. After the upgrade, users will pay lower gas fees, while Dapps will receive more gas fee revenue. Infrastructure providers should upgrade to the latest Blast node that supports 4844.

ChainCatcher news, according to official sources, the Bitcoin NFT Blob team announced the engraving of the rune EPIC•EPIC•EPIC•EPIC on the fourth halving block epic. It is reported that the total amount of this rune is 1 billion, with 950 million pre-mined.
