except now we calculate the max size using the maxPacketMsgSize() function, which frees developers from having to know amino encoding details. plus, 10 additional bytes are added to leave the room for amino upgrades (both making it more efficient / less efficient)

# Configuration
|
|
|
|
Tendermint Core can be configured via a TOML file in
|
|
`$TMHOME/config/config.toml`. Some of these parameters can be overridden by
|
|
command-line flags. For most users, the options in the `##### main
|
|
base configuration options #####` are intended to be modified while
|
|
config options further below are intended for advance power users.
|
|
|
|
## Options
|
|
|
|
The default configuration file create by `tendermint init` has all
|
|
the parameters set with their default values. It will look something
|
|
like the file below, however, double check by inspecting the
|
|
`config.toml` created with your version of `tendermint` installed:
|
|
|
|
```
|
|
# This is a TOML config file.
