From b918ec3abcb002dc6e763fd2dc5aa4d429f7c0a2 Mon Sep 17 00:00:00 2001 From: Evgeniy Stratonikov Date: Thu, 14 Jan 2021 14:17:00 +0300 Subject: [PATCH] consensus: refactor payloads structure 1. `Version` and `PrevHash` are now in `PrepareRequest`. 2. Serialization is done via `Extensible` payload. 3.
