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.
Data security is ensured by encrypting the file when it is loaded into the system with a private key, which is stored only by the data owner. Access to the content of the data is possible only with the help of this private key.
Unique hash identifiers of data are stored in a blockchain database, so it is impossible to delete files, to forge them, or to forge information about storing files. All above mentioned allows unprecedented files protection from deletion and forgery. The motivation mechanism for hosters (people who provide a physical memory of electronic devices for data storage) is aimed at connecting as many ordinary computer users as possible with the system to maximize the
number of independent repositories. Such a system will function with user data protection even if there are no more developers of platform-based applications, developers of the platform itself, or up to 90% of hosters are lost at the same time. Full self-sufficiency, the built-in self-cleaning mechanism and the decentralized nature of the functioning allow the system to exist and work for many years without outside management. The work of Memority is based on its own MMR tokens, the transaction history of which is also recorded in blockchain. The payment functionality is provided by the system of smart contracts, which protects interests of all system participants and constantly cleans the platform from unnecessary files.
The data owner can provide space on his device, thereby gaining the ability to store his data free of charge. This possibility is directed, among other things, to expanding the network of hosters, by including ordinary users in the system of computers.
Memority API allows third-party developers to create desktop and online applications for decentralized encrypted storage of various types of data without a lengthy investigation into the technical details of blockchain technology. Developers are rewarded with 5% of payments for all stored files uploaded through their applications.
The creation of new applications will trigger the popularization of Memority, and an even greater influx of hosters and users, which will positively affect the work of the platform.
Miners receive MMR tokens reward for ensuring the system is operational. Between all the miners who participate in the creation of the block, 5% of the payment for all files, entries of which are contained in the block, is distributed.
The platform uses Proof of Authority, so the computing power is irrelevant to the process of blocks creation and will not increase with time. This is substituted with miner’s authority that they prove by having a large stake in the system. Therefore, a limited number of tokens is issued, and mining commissions will be charged when paying for file storage.
Token investments and the token cost are protected from inflation. This is achieved by limiting the number of tokens and rewarding all participants in the system. In its turn, this will popularize the project and increase invectores’ profits in the long term perspective.

Memority系统使用新的PoA(权威证明)共识算法在EVM(以太坊虚拟机)的基础上运行。这种方法使我们能够将网络速度倍增并降低维持其性能的计算成本。
EVM的选择是以下因素的结果:
1。一个庞大的开发人员社区,他们不断开发这种区块链技术;
2。使用我们自己的私有区块链网络的可能性,这使我们能够独立于以太坊的市场价格(这将显着影响区块链系统中记录交易的成本);
3。现成的EVM工具可用于解决记忆任务。
算法提供文件加密:密码学,Fernet(AES-128) - https://cryptography.io/en/latest/fernet/和https:// github.com/fernet/spec/blob/master/Spec.md
密钥生成由ecdsa机制提供。
本地数据库基于SQLite + sqlalchemy技术构建。
图形用户界面(GUI)建立在PyQt5的基础之上。
与以太坊的互动是通过web3.py进行的。用户之间的交互是通过aiohttp实现的。
