Vitalik: There is no need for a single participant to broadcast all blobs; there are already multiple distributed broadcasting options

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.
