about the darksend open source dillema - how about this, the dev could put on darkcoin.io that the source will be made open once DRK reaches the price of $100 per coin. That would mean it's well established and known by then
There's no guarantee it will ever reach that price, especially if people don't trust it, if would make a laughing stock of darkcoin. It's possible to hire from private firms for a security audit of the code. These are professionals in their field and are probably held to NDAs.
still open source gives people a better "feeling" and is in line with all the crypto - from the people to the people.
A statement on the darkcoin.io site reading something along these lines: "We believe in sharing but we also believe that inovation should be rewarded. To give DRK a fair advantage over the future clones the DarkSend source will be made public once DRK reaches a market cap of X."
I think that's nothing to laugh about
Let the devs at bitcoin and litecoin test it.
Although they are pushed for capacity, it is a feature that will enhance their coins as a optional route for privacy, without having to incorporate the technology into their own coins. They are too caught up in a public acceptance war to incorporate a DarkSend feature at this point, but pointing people this way will give them a solution.
