PANews reported on July 27 that Ethereum core developer Péter Szilágyi (karalabe.eth) tweeted that Ethereum's future direction, PeerDAS, plans to increase the data block size to 32MB in the next upgrade, which will have a negative impact on local block producers. He pointed out that Ethereum's block propagation time is very strict, with only 4 seconds to propagate the block to the entire network. Although PeerDAS has divided the subnet, it still needs to propagate 32MB of data within 4 seconds, which is an unbearable burden for home nodes.
Szilagyi further pointed out that sending 32MB of data to 4 nodes requires 1Gbit of upstream bandwidth, and if the network needs 4 hops, 4Gbits of bandwidth is required, and when considering data propagation, the upstream bandwidth requirement may double to 2.5GBit/s. He is worried that this will lead to the inability of home nodes to continue to participate, and Ethereum is losing its original intention of decentralization. The research team fully accepted the idea of centralizing everything as long as it can be verified. It's a cute trick: decentralized verification, but centralized control.
In addition, he mentioned that some members of the Ethereum research team allegedly run their own MEV relays, and this conflict of interest may lead to a centralized trend in protocol design. Szilágyi is skeptical of the motives of the Ethereum research team, believing that they may be promoting a centralized design in order to profit from it. Ultimately, he is worried that Ethereum is gradually deviating from the principle of decentralization, and even if the price may rise and many people are happy about it, does this mean that Ethereum has "sold itself."
