Complete lies, your questions were answered, multiple times in different ways.
Let's begin debunking some weak shit.
From your
"explanatory" page:
The bit where it gets interesting is this: we use your unique ‘seed’ as a kind of key, as a special input to the function that picks a random number from 1-100. The seed is a product of the preimage on your paid invoice, which we generate using the Ruby programming language like so
Meanwhile on
post #8:
The preimage, so in fact, the input, is generated by lightning and nothing to do with us. Hence fair.
Later, I posted this:
Look after your wording. You're the one who's generating the invoice, and thus the pre-image. Isn't that correct? Your server decides what my invoice will be. The pre-image you generate is strictly correlated with my seed. What prevents you from generating an invoice with non-random pre-image?
And got this as response:
No its not correct. The lightning implementation generates an invoice. We run an LND instance on voltage, we communicate to it server-side.
From the above, I conclude that either you or a third party runs a Lightning node you connect to, server-side, and which generates the invoice whose pre-image clients use as seeds. Therefore, it's entirely possible for the entity that controls the Lightning node to pass an invoice with non-random pre-image. Isn't that correct?
