ChainCatcher news, according to the official blog, the Layer2 network Scroll plans to conduct the Bernoulli upgrade on April 29, aiming to reduce transaction costs by 10 times, depending on L1 Gas fees.It is reported that the upgrade introduces EIP-4844 data blobs for L1 data availability, as well as SHA2-256 precompile support.

ChainCatcher news, at the 2024 Hong Kong Web3 Carnival, Ethereum co-founder Vitalik Buterin delivered a keynote speech titled "Building on Ethereum in the 2020s." He stated that EIP-4844 lays the foundation for future scalability through DAS (Data Availability Sampling). The current DAS can accommodate 3 blobs (approximately 375 kB), the next phase of PeerDAS will support 8-16 blobs (approximately 1-2MB), and the final complete DAS can accommodate 128 blobs (approximately 16MB).

ChainCatcher news, Scroll has released some details about the next protocol upgrade on the X platform, which includes further enhancements to Ethereum compatibility and support for EIP-4844.First, its engineering team has been working hard to make Scroll Mainnet compatible with Dencun. This includes adding support for EIP-4844 data blobs, aiming to reduce transaction fees by 10 times with the help of some additional gas optimizations.In addition, its goals also include the SHA-256 opcode to further improve EVM compatibility and allow for a broader range of DApps and use cases to be built on Scroll.The team is making steady progress in these areas, and before the mainnet deployment, EIP-4844 support is undergoing a period of review. After this testing period, Scroll may be ready to release this protocol upgrade by the end of April. The official team will provide the community with a clearer timeline in the coming weeks, along with the exact date for deploying this upgrade.Moreover, the team is also working on implementing advanced DA compression and increasing support for the Ethereum EIP-1559 fee mechanism, both of which will be deployed on the Scroll Mainnet shortly after the next protocol upgrade at the end of May.

ChainCatcher news, according to Bitcoin.com, Intmax co-founder Mai Fujimoto stated that EIP-4844 has become a reliable solution to address the scalability challenges of the Ethereum network. EIP-4844 is also significant for Layer 2 scaling solutions such as ZK-Rollup and Optimistic, as it reduces the storage burden on nodes and lowers costs.

ChainCatcher news, Synthetix founder Kain Warwick posted on social media that he will create a Memecoin on the OP network for all SNX stakers to test the activity costs after the implementation of Eip-4844 on the network.

ChainCatcher message, Optimism has enabled the EIP-4844 proposal, and the on-chain Gas fee for each transaction has dropped from $0.31 to $0.0004.

ChainCatcher message, Ethereum co-founder Vitalik Buterin stated on Warpcast, "One advantage of EIP-4844 is that it is forward-looking:The only consensus change needed to take us from today's position to full 16 MB danksharding is a parameter change;The point eval precompile returns the modulus, allowing rollups to be built to be forward-compatible with future changes to the modulus."

ChainCatcher news, Ethereum core developer eric.eth posted on the X platform that EIP-4844 will be released on Wednesday, reducing Ethereum transaction fees to $0.01.Previously, the Ethereum Foundation announced the Dencun mainnet upgrade, which is expected to activate on the Ethereum mainnet at 21:55 Beijing time on March 13, 2024, at block height 269568. It is reported that this upgrade introduces temporary data blobs with EIP-4844, also known as protodanksharding, which will help reduce L2 transaction fees.

ChainCatcher news, according to Cointelegraph, Nicolas Liochon, head of Consensys's zkEVM Linea, stated that danksharding (EIP-4844) is expected to further reduce Rollup costs by a factor of 10.Proto-danksharding, also known as Ethereum Improvement Proposal (EIP) identifier EIP-4844, aims to lower Rollup costs. Rollups typically batch process off-chain transactions and data, submitting computational proofs to the Ethereum blockchain. The Ethereum Foundation has not yet determined the expected release date for the prototype of danksharding, and development and testing are still ongoing.Compared to transactions conducted on Ethereum Layer 1, transactions offered by Linea are 15 times cheaper, but Rollups are still limited by the fact that transactions are published in the call data of Ethereum blocks. EIP-4844 will introduce data blobs that can be sent and attached to blocks. The data stored in the blocks cannot be accessed by the Ethereum Virtual Machine and will be deleted after a certain period, which is believed to significantly reduce transaction costs.

ChainCatcher news, Galaxy's Vice President of Research Christine Kim published a summary of the 112th Ethereum Core Developers Consensus Meeting. This week, developers discussed including a builder override flag in the Engine API, raising the target blob limit from 2 to 3, increasing the maximum blob limit from 4 to 6, and ongoing research around changing the maximum effective balance of validators. The increase in blob capacity was proposed by Dankrad Feist from the Ethereum Foundation after conducting data experiments to test the network's capacity for handling large blocks.Parithosh Jayanthi from the Ethereum Foundation DevOps team stated that all EL and CL client teams have passed the relevant Hive tests for Devnet #7. His team plans to launch Devnet #7 as early as June 30 or July 3. Devnet #7 is a dedicated short-term test network for EIP-4844 and will not test other code changes.Additionally, developers are preparing to deprecate the public Goerli test network by the end of this year. To replace Goerli, the Ethereum client teams are launching a new testnet called Holesky, which will host an active validator set larger than both Goerli and the Ethereum mainnet. (Source link)

ChainCatcher news, Galaxy's Vice President of Research Christine Kim published a summary of the 111th Ethereum Core Developers Consensus Meeting. This meeting finalized the scope of the Cancun upgrade, including EIP-4844 (proto-danksharding) and EIP-4788, EIP-6988, EIP-7044, EIP-7045, and EIP-4788. Additionally, developers suggested increasing the maximum effective validator balance from 32 ETH to 2048 ETH and raising the maximum blob count per block from 4 to 6.First, developers discussed which CL-centric EIPs to include in Deneb. Teku developer Mikhail Kalinin provided an update on EIP-6988, which proposes a code change to prevent slashed validators forcibly ejected from the network from being selected by the protocol as block proposers. EIP-7044 proposes a code change to improve the staking experience, ensuring that signed validator exits remain permanently valid. EIP-7045 proposes a code change to enhance network security by expanding the inclusion range of proof slots. EIP-4788 proposes a code change to improve the staking experience by publicly disclosing the root of beacon chain blocks, which contain EVM internal chain state information for trust-minimized access by DApp developers. Ethereum Foundation researcher Alex Stokes stated that there are plans to merge the aforementioned three EIPs into the Deneb specification in the coming weeks and encouraged CL client teams to review them as soon as possible.Meanwhile, the CL client teams have agreed to test the increased blob count on the next EIP-4844 testnet Devnet 6 and will make a final decision on this matter within two weeks. In relation to the discussion around the maximum blob count, Nimbus developer arnetheduck raised the issue of increasing block reorganization on the mainnet after the Shanghai upgrade. arnetheduck proposed considering changing the 4-second deadline to aggregate validator proofs and send them through the network, and decided to investigate further.Ethereum Foundation researcher Michael Neuder proposed removing the 32 ETH staking cap to help reduce the growth of the active validator set. Developers discussed the potential drawbacks of this change and the possibility of launching partial and full withdrawals directly from the EL as part of the proposal for smart contract initiation. Developers agreed to continue discussing the implementation details of asynchronously changing the effective balance of Ethereum validators on ETHMagicians and Discord. Additionally, Ethereum core developers held their first coordination call regarding the launch of the Holesky testnet, which is expected to replace the existing Goerli testnet by the end of the year.

ChainCatcher news, Galaxy's Vice President of Research Christine Kim published a blog summarizing the 107th Ethereum Core Developers Consensus Meeting. Christine Kim stated that after a brief confirmation of the success of the Shanghai upgrade, the meeting began discussing preparations for Deneb. Among them, Ethereum core developer Tim Beiko mentioned that the fifth development testnet for EIP-4844 will be launched sometime next week. Meanwhile, during the consensus meeting, developers proposed to include EIP-4788 along with 3175 and EIP-4844 in the Deneb upgrade.Regarding EIP-6914, developers agreed to continue finalizing the details of the code changes and to push its implementation to a hard fork after Deneb. Additionally, developers discussed the beacon chain attestation subnet (attnets), and Adrian Manning from the Lighthouse (CL) client team proposed a solution for subscribing validator nodes to long-term attnets, stating that this change does not need to be executed through a hard fork.

ChainCatcher message, Ethereum core developers discussed the timeline for the Shanghai upgrade public testnet release and the progress of the Cancun upgrade (the upgrade after the Shanghai upgrade) focused on EIP-4844 during the call #154 on February 2.It is reported that the Ethereum public withdrawal testnet Zhejiang went live on February 1, allowing anyone to request testnet ETH from the faucet and launch their own validators on the network. The Zhejiang testnet currently has 61,000 active validators supporting it, most of which are operated by the Ethereum Foundation.Due to potential configuration issues with the CL software client, the testnet is working to handle new staked ETH deposits. Assuming this issue is resolved in the coming days, developers plan to activate the Shanghai upgrade on the Zhejiang testnet on February 7.If the Shanghai upgrade proceeds smoothly on the Zhejiang testnet, developers will decide on the activation date during the ACDC call on February 9 to release the upgrade on the Sepolia testnet. Developers plan to release the Shanghai upgrade on the Ethereum Goerli testnet by the end of February or early March, and after a successful transition, will turn to the mainnet.Ethereum core developers also spent most of the time discussing matters related to EIP-4844, including gas pricing, transaction validity rules, transaction pool testing, and coupling with blob/block.
