So, just to be clear, we're adding, say, a memory limited mempool or
something prior to release so this fee drop doesn't open up an obvious
low-risk DDoS exploit right? As we all know, the network bandwidth
DoS attack mitigation strategy relies on transactions we accept to

Hey there,
So the essence of this protocol is as follows:
enum PaymentFrequencyType {
WEEKLY = 1;
MONTHLY = 2;
QUARTERLY = 3;
ANNUAL = 4;
}
message RecurringPaymentDetails {
// Namespace for the merchant such as org.foo.bar

There are two possibilities.
One is that the value of transactions with the new lower fee is outweighed
by increased orphan costs and miners refuse to include them en-masse.
Wallet authors lose the staring match and go back to setting higher fees
until such a time as block propagation is

If I understand correctly, the risk here is this would open a historically large discrepancy between MIN_RELAY and the expected minimum fee to actually obtain block inclusion. I don't know if that's true, but I think that's what Peter is saying makes it different this time.The relay network does
Forgive me if I missed it, but the spec doesnt look like it can handle only
handle periods of per week, per month, per quarter rather than 'n period'.
I take Paypal as a reference example for subscription payments where you
can set recurring to every: n days, n weeks, n months, n years. That way a
Given the enormous number of variations on time periods for a
recurring payment, might it be better to simple allow a list of
timestamps? It costs almost nothing, bandwidth wise, and shifts the
thinking to the merchant platform. That doesn't give you an infinite
time frame, but you just get a new
Am suggesting a (possible) mitigation of [possible flooding, etc], via
some kind of discussion (potentially process BIP, related to bundling and

thought and analysis (you mentioned code audit?) before it could be

Hi Mike, Jeremy, Drak,
Before going through your questions, I would like to bring some clarity on a
few key elements in that protocol. There are really two aspects to it:
The contract negotiation; when the user first subscribes, it is prompted by a
contract that will define the payment bounds
