Version handshake
Uzellar orasidagi aloqani o'rnatish ikkita xabar almashinishidan boshlanadi. Avval versiya xabari(version message) yuboriladi va javob sifatida verack xabari(verack message) keladi. Bitcoin wiki-dan version handshake jarayoni illyustratsiya: When the local peer L connects to a remote peer R, the remote peer will not send any data until it receives a version message. L -> R Send version message with the local peer's version R -> L Send version message back R Sets version to the minimum of the 2 versions R -> L Send verack message L Sets version to the minimum of the 2 versions Bu birinchi navbatda uzellar o'zlarining "suhbatdoshi" protokolning qaysi versiyasidan foydalanayotganligini bilib olishlari va o'sha protokol versiyasida muloqot qilishlari uchun amalga oshiriladi.
