Detailed description

DxChain is the world’s first decentralized big data and machine learning network powered by a computing-centric blockchain. In other words, DxChain is a public chain, aims to design a platform to solve computation of big data in a decentralized environment.

DxChain designs a platform to solve computation of big data in a decentralized environment. Consequently, people can use DxChain as a data market to trade data, and create applications on DxChain to meet various needs, including business operation and businesses intelligence. Therefore, by applying blockchain to data storage and computation, DxChain will change the fundamental meaning of the internet.

Solution

  • Maximize individual dataset to its capacity
  • Empower data subjects to control their own data
  • Protect personal data with flexibility
  • Support business intelligence and machine learning DApp

The Master Chain
The Master Chain serves as an Ethereum-compatible, immutable ledger to record asset-related transactions on the network. After data processing tasks are completed, transaction, state and receipt information is stored on the Master Chain via an accounts-based model.

The Data Side Chain
(DSC) facilitates the transfer and storage of data via a decentralized p2p network such as IPFS. Data is broken down into pieces and stored on the p2p file network, while corresponding metadata and a hash of each fragment are recorded on chain. A virtual logic layer called the DxChain Storage Layer sits between the DSC and p2p distributed storage to facilitate the distribution of storage tasks, data transfer and verification. The DSC utilizes a Proof of Spacetime (PoST) consensus mechanism.

The Computing Side Chain
(CSC) provides an environment for organizing and distributing parallel computing tasks between users and nodes on the network. When a user makes a computation request, it is propagated through the network to miners. Upon completion, the result is sent to the CSC for verification. Verification relies on one of two mechanisms depending on the task: verification game (between nodes who stake tokens) or Provable Data Computation (PDS). The CSC then saves a time-bound log of the task and results.

Features

Chains-on-Chain Architecture
The revolutionary Chains-on-chain architecture is designed to solve the data computation, storage, and privacy issues.

Verification Game
Verification game provides a framework which securely perform any computational task and vastly reduces the number of redundant network node computations.

PDC (Provable Data Computation)
PDC is a statistical framework to verify the correctness of computation results with few copies of redundant computing. 

PoSt PDP
The Proof of Spacetime(PoSt) is used as the consensus protocol of storage. It provides the foundation for the decentralized storage network. 

Data Model Enables Privacy Preserving
DxChain does not only provide the data storage function, but it also gives the flexibility of retrieving files at a more granular scale.

    • Token symbol ? Token symbol — a shorten token name. It is used during an ICO and after the coin listing at the cryptocurrency exchanges. : DX
    • Fundrasing target ? Fundraising target — the maximum amount of funds to be raised during an ICO. When it is reached, the developers stop selling the tokens because they do not need to raise more money for the project development. : 21,500,000 USD
    • Token type ? Token type — a platform for a startup launch that influences the stability of blockchain operation, the speed of transactions and the fees. :Ethereum (ERC20)
    • Soft cap ? Soft cap — the minimum amount of funds to be raised for the project development. Sometimes when the soft cap has not been reached, the money is returned to the participants. : NA
    • Role of token ? Role of Token — type of token depending on the opportunities it offers to its owner. Utility tokens give their owners a right to use the project services, security tokens are aimed at bringing profit, and currency tokens are a money substitute. :Utility token

    • Whitelist ? Whitelist — a list of participants, who get an opportunity to buy tokens. To be whitelisted, you need to register on time because the number of participants and the registration period are usually limited. :Whitelist Closed
    • Additional emission ? Additional emission — an additional release of tokens. It can be done once after the crowd sale or on an ongoing basis. In the projects with a limited emission there is no additional emission. :No
    • Exchange listing ? Exchange listing — an assumed date when the token will be listed at a cryptocurrency exchange. The developers usually indicate it in a roadmap and a white paper. :NA
    • Accepting currencies ? Accepting currencies — cryptocurrencies and fiat currencies that can be used for buying the project tokens. :ETH,
    • Can't participate ? Can't participate — the countries where it is prohibited to buy tokens. These can be countries where ICOs are prohibited altogether, or countries that have the requirements that a particular project does not meet. :Canada, China, Cuba, Ethiopia, Iran, Iraq, Libya, New Zealand, North Korea, Serbia, Somalia, South Korea, Sri Lanka, Syria, Tunisia, USA, Venezuela, Yemen,
    • Know Your Customer (KYC) ? Know Your Customer — a verification procedure for ICO participants, during which the developers can ask for personal data, a photo and a scanned copy of a passport of a potential investor. :Yes
