All the configurable options for the dealer are set in dealer_setup.ini, which is located at the path bet/privatebet/config. The default configuration settings are as follows:
[dealer]
dcv_commission = 0.5 #This is the percentage of the pot amount that dealer takes home as commission.
chips_tx_fee = 0.00050000 #The default tx_fee is `0.0001` dealer can set any amount greater than minimum tx_fee.
type = ipv4 #When this set dealer only allows LN nodes running on torv3 to establish channels with it. This feature is not activated yet.
gui_host = "" #If the GUI is hosted on the same backend node then it can be left blank, else the URL on which the GUI is hosted must be provided.
bet_ln_config = N # Set to N(no) if the dealer intends to record the game info on the CHIPS blockchain, else Y is the dealer intends to use lightning network to record game info in ln invoice.
[table]
max_players = 2 #This is the maximun number of players that dealer will allow them to join the table. Atm, dealer waits for this number of players to join before starting hand.
big_blind = 0.001 #If this value is set the table stake size is calculated based on this which is 200BB, if this value is not set the default value is 0.01.
min_stake = 20 #The min table stake size is 20BB.
max_stake = 100 #The max table stake size is 100BB.
[private table]
is_table_private = N #By default the dealer tables are public anyone can join the dealer table, if is_table_private set to "Y" then the dealer table is considered private and players has to provide the table_password in order to join the table.
table_password = pangea #If the table is private dealer must share this password with the players by any offline/online mechanism which is outside bet scope.
There are no conditions/constraints to become a dealer are set yet. If you have a machine with the static public IP you can simply host your own dealer node and become a dealer. You even can host private poker tables to play with closed groups, friends and family.
In relation to this there is some discussion going on here. It's still open, you can share your views on it.
