"bitSIM will enable anyone with a mobile phone to securely own and perform Counterparty and Bitcoin transactions and streamline access and control of their Blockchain Assets. Vennd.io will provide the basis for liquidity providers to list their assets on a secondary market rather than a centralized registry. Details of the first instrument to be listed for sale will be released in the following weeks."
