How it works

ExtraChain (ExC) is a lightweight blockchain infrastructure and decentralized storage “ExDFS” allowing creation of high-load dApps (decentralized applications) for both portable, non-portable and IoT devices.

Distributed File System (ExDFS) is shared data storage and serves as an main support module for ExtraChain DAO Framework.

One of main ExDFS elements is Historical Chain. Historical chain is a data structure that holds all changes made in a particular file, including creation and removal, like DNA of living beings.

Benefits

Distributed architecture with high scalability

Nodes are sharing their resources to increase productivity and new nodes and users create relatively small computing pressure on entire network

Fast and reliable network

ExtraChain combines advantages of Proof-of-Stake and Directed Acyclic Graph architectures

Cross-platform

ExtraChain Framework is aimed to bind as wide variety of devices as possible

ExDFS

ExtraChain Framework opens access to a distributed file system that connects all network participants. Framework users and dApps can store their app data in a secured and reliable way

All possibilities of base currency are applied to tokens

Tokens inherit all native functions of base coin as Staking and Token Fee. Token creator can enable them at creation stage

ExtraToken creation requires only icon choice

Estimated token creation time – 3 minutes

ExC Store

Is the ecosystem for ExC-based DApps, uniting different apps in single all-purpose network;

ExC Automated Exchange

Is a DeFi-exchange platform, aimed to support ExC products via fast, easy and community-driven interactions.

Extra Coin

ExC is a universal unit in ExtraChain blockchain.

Everyone can earn it!
In different ways:

Stake

  • Stake ExC and receive rewards on each verified transaction

Store

  • Save network data, share it with other users and receive reward for each data request

Farm

  • Store ExC in Automated Exchange pools and receive fees in ExC

Everyone can use it to participate
in everyday life of network:

Help the network to evolve, use tokens to govern your own DAO or share it with other users;

Support your app or service, reward storagers (users who store data for your app) with ExC;

Grow your own ecosystem inside ExC and feed it with ExC to create polls, reward creators and interact with other communities in secured, trusted and healthy way.

We are not bounded
by only ExtraChain ecosystem.
With help of our automated bridges between Ethereum and other blockchain ecosystems.
And our first step will be ERC20 ExtraTokens two-way swapping to ExC according to roadmap.

Roadmap

    NOW:

  • ExC Blockchain architecture was created and developed

  • Historical Chain data structure was developed as basis of data exchange in local filesystems

  • Historical Chain was implemented as data exchange control tool for Distributed File System

  • ExDFS (Distributed File System) was implemented as basis for DrApps

  • ExToken Module was built

    To be Continued...

ExC Blockchain is lightweight PoS/DAG infrastructure for DApps and DServices.

ExtraChain was built with the main idea in architecture: connect as many platforms as possible and implement full decentralization of decisionmaking and data storage in network. ExC nodes are sharing stored resources between each other to empower low performance devices, such as smartphones.

Distributed File System (ExDFS) is a shared data storage and main distributed space of interaction for DApps and DServices. ExDFS consistency is protected by Historical Chain.

Distributed File System can be used in various ways. It can:

  • Hold user data of DApps and DServices;
  • Distribute files between users;
  • Authorize access to files;
  • Differentiate access rights for users;

All these possibilities create stable and protected distributed file storage that can hold any amount of files without corrupted links, order and state errors.

ExDFS is protected by cryptographic methods of ExtraChain and allows to build secured and anonymized decentralized apps, without any need in localized data storage.

Historical chain is a data structure that holds all changes made in particular file, including creation and removal.

Historical chains are used to:

  • Contain data changes;
  • Organize data changes;
  • Order changes in a non-time-based way;
  • Secure data changes (changes are non-removable);
  • Proof of Existence (file can be retrieved on each state of change);

ExC Store is the most powerful tool for ExC DApp integration:

ExC Store is a place, where ExC-based DApp can be shared and integrated with other apps and services, that are using ExC Framework.

ExC Store includes several interactable API-s and ExDFS resources to ensure that every app, created with ExC Framework, has possible access to other user-created services. ExC Store offers several ways of interaction:

  • Coin-Token interaction: different apps with different internal tokens can work together via “quick exchange” mechanism from ExC Automated Exchange (see below);
  • Service integration: apps built as services can be integrated into other apps via standardized APIs. User-created payment service integrated in other apps can serve as example;
  • Data integration: single-profile authorization and peer-to-peer data exchange between apps. Apps can interact with ExC user profile to extract basic data for authorization and share their unique-named fields of user profile. This type of interaction serves for unification of access and data management;

ExC Automated Exchange is ExC-based, integrated exchange service, built on DeFi principles.

Every ExC-based token (ExT) has the possibility to enable exchange pairs with other ExT-s. Only requirement for token creators is to maintain a liquidity pool for desired exchange pairs. Also, ExC Automated Exchange is community-driven, so everyone can participate in liquidity pool maintenance via DeFi farming.
