sorry for the wrong mention. I corrected it.

What I am trying is not relaying, ety001 provides latest snapshot of witness block data. If I copy the data into the blockchain folder, then the rpi tries to sync from the data. I guess it will sync in a few minutes.

Yeah, wallet things seem weird. I forked @ety001's steem-docker-ex. I could generate a brain key not on rpi4 but on my linux machine (it was not working in Apple M1).

Thanks to the info. I will look into the cli_wallet stuff.
