ENDO A PROTOCOL AND VARIOUS DATA VERIFICATION SERVICES

UPIK05

INTRODUCTION

ENDO is a Blockchain, a protocol and various data verification services. The Ecosystem of the ENDO protocol creates a decentralized environment for verified data. Data that people and robots will be able to trust: remotely, instantly, and safely.

Using the ENDO protocol, you can create private and public Blockchain, configure levels of access to information, the conditions for data exchange between different organizations, and depersonalize and protect data.On the basis of the ENDO protocol, applications have been created that allow the transfer of paper documents with ink signatures to digital ones; a person can receive a digital certificate of their identity; brand things to create a digital passport of authenticity.Anyone will be able to create their own applications based on the ENDO protocol as early as the beginning of 2019.

The ENDO Ecosystem allows organizations and users to participate in the information exchange process and use the services with the ENDO token.All ENDO applications and products have one goal – to create a single, secure and certified environment for any type of data.Now you can manage your personal, corporate, and public information about achievements, awards, indicators, transactions, etc., using the ENDO platform. By your consent, the platform provides secure access to your stored information to third parties.

Problems of Information

In the modern world there are problems related to information :

Deceit-people can deceitfully receive value.
Loss for storage – the storage of formal information is expensive. In the transfer of securities, the human factor is still involved.
Centralization of data validation – the monopoly of institutions on the management of valuable information: change, removal and censoring.
Fake systems – the problem is not enough for anyone obvious. But we all live in contact with systems that can deceive. And it is almost impossible to prove, because fraud is embedded in the system itself. For example, culture and history. Although, we will return to the examples.

Solution

Storage of data occurs both centralized and decentralized. The owner of the application produces the storage choice.ENDO implements interfaces for connecting to storage of different types, so that connected applications have a greater choice for solving the problem of data storage.Data can be stored:

1.In centralized cloud – Dropbox, Google Drive, etc.,

2.In decentralized cloud – StorJ, IPFS, etc.

3.On local / remote servers: connection via FTP, SSH, etc.

4.On the nodes of the ENDO blockchain system in the decentralized storage based on IPFS.

Local storage allows you to deploy a completely private network within the enterprise. This guarantees protection from data leaks and the ability to exchange data between a limited range of agents.

Distributed Registry Technology

Blockchain technology enabled companies to supply more reliable systems for verification and data management. Distributed registry technology can provide an easily accessible tool that can improve business processes of data exchange, asset management, system state changes.Cryptographic algorithms prevent the appearance of false information between the participants in the event that it falls into the hands of scammers.

These functions allow companies to maintain the security of confidential commercial / personal data and at the same time to be efficient and easily manageable, for example, medical or financial institutions.

Business Challenge

ENDO is a set of subsystems that interact with each other to fulfill the set business objectives:

Increase the level of trust in important data.
Reduce the likelihood of counterfeiting data.
Ease of access to data.
Decentralized model of data access.
Flexible and convenient control of data exchange.
Create a standard ontology for different types of data for typing and simplifying the exchange.
Single source of data monetization.
Ability to control access to the user’s own data.
Ability to influence the preservation / deletion of user’s own data from companies.
Ability to monetize user’s own data.

Requirements

The set business tasks form the requirements, the fulfillment of which is obligatory for solving the problems:

Data must be encrypted at all stages: only the issuer and the data owner must have access to data management.
The verification task and access control should be carried out in a decentralized manner to ensure a proper level of trust.
The system capacity must be high, because potentially the market of important data has a larger volume.

Subsystem Architecture

Protocol

ENDO Protocol is a set of rules, algorithms, and business process logic, describing the interaction of subsystems among themselves. The ENDO protocol regulates the overall interaction between network units, allows them to communicate securely and transfer data among themselves. ENDO Protocol describes the following entities and processes:

Data verification.
Hashing, data encryption.
Algorithms for providing access to data.
Cryptography The cryptography used to protect data, and the interaction between applications.
Structure of the open and closed software interface.
Ontology of the data.
Structure of data storage, the structure of interaction with local and cloud storage.

Modelling

A unified model of data representation and adaptation of this model to the main entities in the applied cases is implemented. Models are needed to realize the possibility of more complete interaction and data management. Each object that appears in the system has a model. All models consist of:

meta-information (issuer, owner, model creation date, serial number)
the hash of the object’s body.

In addition to unified models, narrowly-focused variants of abstraction models are implemented to operate various uses. Models solve specific problems of representation of data types and their contents. The task of modeling is to realize the possibility of maximum automation of processes, such as:

the interaction of data types between different applications of the system,
communication model and data type.

As a result, the degree of influence of the human factor is reduced, allowing applications to communicate automatically on the basis of automation and algorithms, which leads to the preservation of system stability.

Blockchain

Blockchain is an important link in the system and contains data and logic that require a high level of trust. Since, from the point of view of the cost of storage and data processing, Blockchain is an expensive solution, it is necessary to select the minimum required set of tasks to ensure the proper level of trust.

Necessary tasks

1. Data verification, storage and creation of hashes of data.

2. Authentication of users and companies.

3. Storing of open data of applications and companies (application identifier in the network, open documents about the company owner, etc.).

4. Managing tokens and their transactions.

5. Decentralization of the logic and data of the scoring system.

6. Ensure the download and execution of custom smart contracts.

Characteristics and properties

ENDO Protocol can be implemented on the basis of any platform that is able to solve these problems. The most suitable platform with the following characteristics and properties:

1. Low transaction costs.

2. High bandwidth with a high degree of scalability.

3. Ability to publish custom smart contracts.

4. The ability to implement a communication channel between two or more registries.

5. A model for managing economic parameters based on voting.

Algorithm of consensus and platform

The most suitable consensus algorithms are “Delegated Proof of Stake” and “Byzantine Fault-tolerant Consensus”.

They have a high capacity, low cost of storage and processing. Such Blockchain platforms as EOS, Hyperledger, Corda, Exonum allow to implement business logic ENDO Protocol.

Implementation in ENDO

As a test of business cases ENDO Docs and ENDO Base, we implemented the basic part of the protocol based on the Graphene Blockchain platform. At the moment, our team is working on more narrow cases, analyzing vulnerabilities, testing the effectiveness of the protocol; implementation of the protocol based on the fork of the EOS platform as a public ENDO network, and Hyperledger as private network of organizations.

Token

EToken is an internal platform token. EToken is the only means of exchange that can be used to pay for checking data and exchanging data between users of the system.

Why do we need EToken

Verification of data – the process of storing information on Blockchain. The decentralized platform is supported by nodes, respectively, a token is needed to stimulate network members to maintain the system.
EToken is needed for data exchange between organizations – they set the cost of data exchange between each other.
Etoken can be used when receiving services or paying for goods related to the use of verified data.
EToken is used to vote for the development of the protocol and determine the economic parameters of the system.
EToken is used to stimulate developers who create applications on the open Blockchain protocol of ENDO. The percentage of tokens from transactions through the application is awarded to the creator of said application.

ET Use-Cases

For Organizations

To verify data in a public Blockchain.
When exchanging verified data between organizations registered in the network.

For Users

The user can order a service from a provider or application on the network. Examples: pass the KYC procedure at a notary; translate the document by a professional translator.
When performing transactions between two network users: buying items in the store application.

In the future

In the future, if there is a lot of data, the user will be able to receive ET with the consent to share them with the companies. If we draw an analogy with the present time, Google would reward users for providing their data to advertising companies.

This will create a trusting relationship between ordinary people and corporations and will stimulate users to share their data without feeling deceived.At the moment, information is a valuable asset. Companies earn millions on this, and ordinary Internet users do not get their share.
