I don't know why you're calling me out with that sort of language. I sincerely want this project to succeed. I also don't think you quite understand my concerns as you don't address them directly. I feel, in practice, no one will buy inexpensive items because it's silly to put down a deposit on a $4 item. And I feel, in practice, no one will buy expensive items because putting a chunky deposit down might be out of possibility for many, or may seem absurd or unfair. In a very real way, people are losing money by having it tied in limbo and I feel most understand that on a visceral level even if it's not something everyone can articulate.
Regarding a scamming buyer, whats to stop someone from opening burner accounts and getting a bit of rep with the intention of ripping off a seller who doesn't require a full deposit? I didn't understand your response?
Who backs the bonds? Who foots the bill if the bond buyer renegs?
I ask simply how can you deliver in practice, how does it work..and have yet to get a straight, concise answer that makes sense when applied to the chaos of real-world markets and irrational actors.
Where's the whitepaper? For what passes as a whitepaper these days you can [and should] outline the broadstrokes for idiots like me. Saying you don't want people to copy your work is a silly reason not to draft a whitepaper. It's like that wannabe writer everyone knows who won't share his idea cause someone will steal it!!!

Fear of mimicry is really just the fear someone else will do it better. It speaks to a lack of confidence in the execution.
If this thing is almost done why can't you or any of your myriad supporters explain how double deposit works in practice, and why people will choose to use it over existing players in this space. Zero fees is a good place to start but it's not enough to entice the first wave of people IMO.
I'm not up on the etiquette around here...in fact it's a lack of general etiquette that keeps me away. If this thread is merely to pat one another on the back then forgive my intrusion. However I assumed this was a place to engage in informed discussion. I'm not a rich person and chose to back this project with what few spare shekels I have because I found the goals relatable and respected the perseverance and seeming integrity of the dev. Starting to feel like I've made a mistake.
