Memority is a blockchain-based platform for encrypted decentralized cloud storage of valuable data. Memority’s mission is to create a self-sufficient ecosystem that includes many applications to meet the needs of businesses, government organizations and individuals in the super-secure storage of all kinds of valuable data. The platform includes a collection of independent repositories from around the world, which are based on computers of users who have provided a part of the memory of their hard drives for file storage. To ensure a high degree of data security, 10 copies are created for each of the stored files, integrity and authenticity of which are constantly monitored. If the number of file copies is insufficient or the copies have been forged, new copies of the original file are automatically created for new hosters. The processes for verifying availability, authenticity and recovery of files are independent from the file owner and will work autonomously as long as the files storage in the system is paid for.
