Just curious, why is no darknet market that I've heard of built completely around Monero?
Why hasn't anyone here made one?
Because Monero is still being developed. Correctly, as of today, all serious darknets are operating (trustless) multi-sig-escrow-process, so they require Cryptocurrencies with good proven MS escrow features/process, which is a feature that isn't built today in Monero.
As
assured before (by Monero community members with good connections and knowledge in DM operating scene),
when both sides are ready Monero project (with software and ecosystem) and DM scene is ready (admins: with building trust in Moneros stability, hopefully chosing cryptonote technology as the prefered privacy coin, users/vendors: getting to know about Monero, learning Monero-usage incl. the multi-sig-escrow process, building trust, having easy access to Monero via exchangers, enough secure cashout possibilites are established)
there will be big, leading Darkmarkets that will list Monero.
(Not all big ones from the start, but 40% up to 60% of the big ones like 3 out of 5, could be reached.)
But it will take around 12 months. Also remember
it's a big, big step and major game changer for the whole DM community, they all (users, admin and vendors) have to reach an agreements about which anon coin to support. They are all depending on each other.
Drugs users and vendors are heavily using themselves and dont have much computer skills.
---> usability and simpleness of use for CC clients and tools (like scripts helping vendors and admins in management of there multi-sig-escrow-proccesses), will have a strong influence which what is becoming the preferred solution
Dont be fooled by the fact that some unknown market with nearly zero users and no non scamming vendors may be testing Darkcoin (in order to create some hype for its market or at least get traffic from dark community), or
Coin123-supporters are using an public darkmarket script like Bit-Wasp and change it to their coin and setting up another DM no one knows, wants and which has by design zero future.
Or desperated marketeers of weak anon coins, will donate bribe to desperated admins of very small, unrelevant DM markets that generates zero incoming, so they halfheartedly implement their coin as marketing gag (and in most cases the DM is gone 6 weeks later anyway or the cashin feature of the coin that paid the bribe is deactived for various reasons, like being buggy/unstabil, no demand, bad desgined, ...).
Don't worry, there is no other anon coin with a better position in this battle to succeed Bitcoin as preferred DarkMarket coin and Monero already has a very good standing/reputation in the mind of important and influental in the DM scene.
But still, there is a long way to go. And alot of work to do. Everybody should contribute as much as possible, of whatever he can offer that helps the project, not only code and donated coins, but also man power and free working time, for executing the many open tasks or to be developed services and solutions Monero needs.
