The Hardnose Rule for Hardnose Bankers

Problem: How can Greenlist get to scale without simultaneously attracting every bank to become a registrar?
Answer: Permit consumers to register themselves directly, a la Paypal.
Tactic: Invite all Paypal users via their chat rooms, etc.
Explanation: Primary tenet of Greenist is its utter safety of resolving identifiers into routable bank payment addresses THAT CAN NOT BE DEBITED.
Solution: Restrict access to query the Greenlist to participating banks' web portals. Banks obtaining access must guarantee that any ACH numbers listed will NEVER be debited by their payment engine.
