This specification defines the “eth” ENR entry, which provides information about the eth capability on a certain node.
Entry Format
entry-key = "eth"
entry-value = [[ forkHash, forkNext ]]At this time, the “eth” entry is a single element list containing an EIP-2124 fork ID
value. Please see the EIP for definitions of forkHash and forkNext.
In order to be compatible with future versions of this specifications, implementations
should ignore any additional list elements in entry-value.
Change Log
EIP-2124 (May 2019)
The initial version of the “eth” entry was proposed in EIP-2124.
