Hi there, Through your project description, it seems you guys have implemented private blockchain and want to connect different peers (slaughterhouses, packaging companies, retailers) into your system and I think we can be a great asset for you in developing the API. Building an API is one of the easiest ways you can do that but the only problem here is that each division has to integrate and link your API within their system (Additional Development work for each division) so whenever they submit their data in their system, we can collect the same information through our API. About Us: My team and I have experience and expertise working with blockchain technology and the last 1 years we have helped companies to develop blockchain-based products from scratch. Few of our notable work includes: 1. Blockchain Platform for Education Institutes in Africa to Issue their certificates and diplomas through blockchain to remove the fraud and duplicity. 2. Blockchain-based Point of Sale System for retail stores in the USA to cut down the processing time and cost of merchant payments. Apart from that, we have also developed a few POC solution for crowdfunding and the real estate sector. I would be happy to share more information about our products and experience and interested to learn more about your project and business logic. Interested to talk more? Thanks, Jai
