a. Objective(s)

bConnect platform begins to be used by Brazil, Argentina, Paraguay and Uruguay to ensure more agility and security in the exchange of information on foreign trade. bConnect is a tool that allows the network sharing of registration information of companies certified by the Federal Revenue Service as an Authorized Economic Operator (OAS) and that enjoy benefits such as facilitation of customs procedures, both in Brazil and abroad.

bConnect was created to supply an international need of automated exchange of customs data of the OAS between the countries, that, before, was made, in its majority, by means of spreadsheets elaborated or extracted from the system that each country had and sent by electronic mail

The bConnect network begins by allowing the sharing of information from Authorized Economic Operators (AEO) and there are already plans to increase the network to meet the sharing of information from Customs Declarations. 

the bConnect solution was developed using the Hyperledger Fabric 1.4 framework, an open source application maintained by The Linux Foundation.
