By default, Charon adds a charon/<version>-<commitSHA> graffiti to all block proposals. This can be customized using the --graffiti and --graffiti-disable-client-append CLI flags.
The --graffiti flag accepts either:
A single string, which will be used by all validators, or
A comma-separated list of strings, allowing each validator to have a unique graffiti (one string per validator).
When possible, Charon automatically appends an Obol signature (OB) and the specific consensus client type used (<CL_TYPE>) to the end of the custom graffiti. This behavior can be disabled by setting the --graffiti-disable-client-append flag.
The graffiti field in block proposals has a maximum size of 32 bytes.
