MARAChain

Business to Customer (B2C), Customer to Business (C2B) or Person to Person (P2P) Exchange of digital documents, complaint at all levels with GDPR with option of temporary storage, through blockchain technology and the use of programming languages such as PHP7 and Node.JS that allow rapid development of applications.

Thanks to these technologies, the Marachain project will have the following major features:

1. Scalability: in storage and development, given the open-source nature of the technologies used.
2. Security: The documents shall be compressed and encrypted by a double AES256 system, preventing access by any person who is not the addressee and / or sender. The technical staff will not be able to access the content of the transmitted documents. In case of loss of credentials, the received and sent documents will not be accessible with secondary verification like Electronic ID. “Security Certification”.
3. Verifiability: Every document sent is verifiable at any time, without the need for signatures or verification codes. Just by uploading the document to “Verification Area” it can be known if the document has ever been stored in the system. Sender Name along with date and time stamp shall also be provided at the time of verification. This verification can be carried out even if the document has been deleted from the data warehouse and is known as “Transmission Certification”.
4. Auditability: Any authorised person or entity such as auditor or regulator shall have access to the record book (not the documents), allowing to know, in real time or real-time, the use of the system as well as document transactions. Given the private nature of data, the underlying data will not be displayed.
5. KYC: A Sender may send documents to any person or body but only on the registered email address of the recipient. KYC verification of the recipient is a must before a sender can electronically transmit any document. As soon as the , the system will ask for ID or Passport accreditation, as well as a photo of the person (selfie), to proceed with the verification of the identity. Once verified, the user will receive access credentials to the platform, here you´ll be able to read all documents received.
6. Access: The registration of access to each document sent through the system is enabled, allowing the sender to know if it has been delivered , read or not by the recipient. “Reading Certification”.
7. Speed: Document transactions will be performed immediately and without any human intervention, allowing the sender to have delivery certification.
8. Redundancy: Given the distributed nature of the BlockChain technology, all information and / or document stored in the system will be replicated in each project server (never less than 3 servers), which have certification of location within the EU, an essential requirement for compliance with the GDPR at the lowest level. This way, in case of loss of a server for any reasons, the system will not be affected.
