So you have to ask yourself. What is Silk coin doing that is creating UTILITY? What is it doing that other coins are not doing?
And.... What is Silkcoin NOT doing that other coins are doing?
- BIP 0021 "URI Scheme" to enable payments by clicking on link or scanning QR code
- BIP 0070 "Payment Protocol" for better communication between merchant & customer
As a web developer in the finance industry, I see these 2 BIPs as vital for any crypto currency that wants to have merchant services built upon it.
