First part of a handshake, sender advertises its version and characteristics.

Fields

protocol version of the sender

capabilities of the sender

randomly generated for each handshake, helps detect self

genesis block of our chain, only connect to peers on the same chain

total difficulty accumulated by the sender, used to check whether sync may be needed

network address of the sender

network address of the receiver

name of version of the software

Generate a short_id via the following -

  • extract k0/k1 from block_hash hashed with the nonce (first two u64 values) * initialize a siphasher24 with k0/k1
    • self.hash() passing in the siphasher24 instance
    • drop the 2 most significant bytes (to return a 6 byte short_id)
