MARAChain allows transmission of encrypted and secure documentation, restricting access to third parties and offering access management to these creditable transfers, through an auditable, verifable and secure P2P transaction. These transmissions will be made through a distributed network of nodes located in the main European DPCs, guaranteeing 24×7 availability of information as well as protection against information loss thanks to the redundancy of our network. MARAChain provides layers of personal data privacy using InterPlanetary File System (IPFS) coupled MARAChain private blockchain. Clients who send/receive documents get to enjoy the simplicity of secure, private, encrypted file sharing and storage as well as decentralized peer-to-peer properties. The distributed network is formed by a series of interconnected nodes, located in european datacenters. The network is protected against all types of DDoS attack, thanks to nine anti-DDoS infrastructures with a capacity of 6×600 Gbit/s + 1×240 Gbit/s + 2×120 Gbit/s in each datacenter; in this way we can mitigate up to 4 Tbit/s permanently. In addition, the datacenters have the ISO 27001:2005 certification for the supply and exploitation of dedicated infrastructures; and the management of security and risk assessment is based on the ISO 27002 and ISO 27005 standards.
