 We share our Network Protocol with server partners so they can write their own Minecraft servers with their own code. This documentation compiles a series of tree diagrams that define the structure of the packets used by the Protocol, as well as related classes and enums.
 Protocol is subject to change release over release.

-# Common values for player movement
-# Allowed values: "client-auth", "server-auth", "server-auth-with-rewind"
-# Changes the server authority on movement:
-# "client-auth": Server has no authority and accepts all positions from the client.
-# "server-auth": Server takes user input and simulates the Player movement but accepts the Client version if there is disagreement.
-# "server-auth-with-rewind": The server will replay local user input and will push it to the Client so it can correct the position if it does not match.
-# 		The clients will rewind time back to the correction time, apply the correction, then replay all the player's inputs since then. This results in smoother and more frequent corrections.

 # This is the tolerance of discrepancies between the Client and Server Player position. This helps prevent sending corrections too frequently
 # for non-cheating players in cases where the server and client have different perceptions about when a motion started. For example damage knockback or being pushed by pistons.
 # The higher the number, the more tolerant the server will be before asking for a correction. Values beyond 1.0 have increased chances of allowing cheating.
