FULLNODE - KEYSTORE FOLDER

[vinatechpro]

A file in the folder named keystore is the seed of the wallet which is used by the node?
For what purpose is it used?
~/avail/output/chains/avail_goldberg_testnet/keystore

I have also paid attention to this matter and am equally curious.

I found out the same and I would like to know this too.

It's generally used to sign stuff as a validator / authority, you can learn more here : https://docs.substrate.io/tutorials/build-a-blockchain/add-trusted-nodes/

Especially in the Add keys to the keystore section
