Bitcoin Stop Chain is a private encrypted network that converts your Bitcoin into a digital gift certificate of equal value. These certificates can then be traded, sold, verified, reissued or turned back into Bitcoin at anytime. The main advantage of using Bitcoin Stop Chain is that we do not maintain a private or public ledger. This enables you to keep your transactions completely anonymous and out of the public Bitcoin ledger - otherwise known as the block chain. Vendors are encouraged to accept Stop Chain Gift Certificates by hooking into our Vendors API. Stop Chain Gift Certificates can be converted back into Bitcoin for 0.5% + 0.0005 BTC. There is no fee to reissue a certificate.
