Sender, before sending the file, generates the hash of the file and store it on blockchain network.
Receiver, after receiving the file, generates the hash again.
If both the hash matches - this implies that the file has not been modified over the traffic.
Filegateway file upload and many other protocols like AS2, FTP, FTPS and SFTP do not address non-repudiation. Once we have this feature into the product it will be a great security addition.
USE CASE 3
Description: B2Bi plays a major role in integration between external world (partners) and internal departments within an organization through adapters and services.
Blockchain is going to be used not only with external partners but within the organisation among different departments as well - to establish trust.
Said that, an organization is going to be part of multiple blockchain networks (external and internal).
And there could be need to share permission-able information from one blockchain network to another blockchain network.

B2B Integration & Blockchain-era EDI system
From a supply chain perspective, much of the hype surrounding blockchain lays within its promise and ability to relieve many of the problems of traditional B2B Integration and EDI.
Electronic Data Interchange (EDI) made transaction processing digital and automated. EDI replaced manual, paper based business documents. It has been the gold standard for integration between businesses and exchange business documents such as purchase orders, invoices, and shipping notices.
However, EDI has been plagued by the ever-growing number of standards and ways of doing business. Document formats such as: EDIFACT, ANSII X12, CSV, and XML, and communication protocols such as: SFTP, Connect:Direct, HTTP, and AS2 – have become a plethora of “standards” which are inconvenient and time consuming for organizations to maintain. It is costly and complex to build systems which can transform data from Company A’s format to Company B’s.
Blockchain however, has the ability to provide a single standard, framework, and database – which will provide one single view of transactions, simplifying:
• Visibility
• Auditability
• Dispute resolution
