ChainCatcher news, according to the summary of the 129th Ethereum Core Developer Meeting, the Ethereum Cancun upgrade will be activated on the mainnet at Beacon Slot 8626176 (expected to be on March 13 at 21:54 Beijing time). The main content of this upgrade includes EIP-4844 (Proto-Danksharding), which aims to reduce Ethereum gas fees by using blobs to carry transactions.

ChainCatcher news, OP Labs CEO Liam Horne tweeted that Ethereum core developers will hold a conference call on Thursday to discuss the inclusion of EIP-4844 in the consideration framework (CFI). However, "inclusion in the consideration framework" does not mean that EIP-4844 will be included in the next hard fork; the content of the Shanghai upgrade will be discussed separately.It is reported that previously, Vitalik Buterin shared the idea of Proto-danksharding on Twitter (EIP-4844), which focuses on data validation scenarios for blob-carrying transactions that cannot be executed by the EVM. Proto-danksharding will replace Danksharding, a sharding technique where only one proposer selects all transactions and data entering this or that slot, rather than selecting a separate proposer for each shard. The solution proposed by Vitalik could be a temporary variant, as it includes the implementation of some sharding techniques. At the same time, it leads to an increase in data usage, as it requires a larger block size. Vitalik proposed to automatically delete blob data every 30 days to prevent excessive demands on data and memory storage from the network. (source link)
