We already have AUTHORIZED_DECRYPTERS env, which decides which addresses are authorized to decrypt data.

Managing those address (add/remove) is cumbersome, cause it needs a restart of the node. But we have accessLists, so :

• add AUTHORIZED_DECRYPTERS_LIST env variable, which looks like

{
 "1": ["0x123","0x124"],
 "2": ["0x345"]
}

which means:

• for chainId 1 , call "balanceOf(ADDRESS_TO_CHECK)" on contracts 0x123 and 0x124
• for chainId 2 , call "balanceOf(ADDRESS_TO_CHECK)" on contract 0x345

This way, node owner can use accessList contracts to define list of addresses.

Ocean-node will check both AUTHORIZED_DECRYPTERS and AUTHORIZED_DECRYPTERS_LIST (if they are defined) and if an address is a match on any , then it's allowed
