Detailed Description¶

struct discv4::ForkId;

Fork identifier per EIP-2124.

Mirrors go-ethereum forkid.ID:

type ID struct {
    Hash [4]byte   // CRC32 checksum of genesis + applied fork blocks
    Next uint64    // Next upcoming fork block/timestamp; 0 = none
}

Wire encoding inside an ENR eth entry: RLP(enrEntry) = RLP([ RLP([hash4, next]) ]) (outer list = enrEntry struct, inner = ForkId struct)
