Ethereum core developer smartprogrammer.eth submitted a new EIP request.
The purpose of this EIP is to introduce a new version of the Ethereum peer-to-peer network handshake protocol (eth/69, the current protocol version is eth/68), allowing Ethereum nodes to communicate their available block ranges.
So that nodes can make more optimal decisions when choosing who to connect to, this can also be regarded as a step towards EIP-4444 (historical data expiration).
It is understood that this EIP belongs to Networking EIPs, which are specific to optimizing the Ethereum point-to-point network.
