What Is DxChain Token ? (DX) Complete Guide & Review About DxChain

About DxChain Token

DxChain Token Functionally, the entire system is designed as a platform to provide big data and machine learning related computation services with the support of decentralized data storage services. Database query and business intelligence tasks are performed for data that could not be owned by any commercial company but can be traded and stored on the Network. This platform is designed to connect personal computers, as well as specifically designed miner machines, to potentially facilitate easier data computation at a lower cost. Network provides two fundamental capabilities: computation and storage. Currently, only big companies have the capability to run big data tasks, because not only can these companies afford expensive hardware but these companies also own most of the existing consumer data.

DxChain Token For example, Google possesses the navigation data of whoever that uses Google Maps. If Google Maps users could find a way to sell their navigation data, then they will do so for economic reasons. Users will not worry about their privacy since the data has already been seen and used by Google. If third parties can sell navigation data, combined with other commercial data, then advertising campaigns will be more accurate and customized.

DxChain Token Most importantly, big companies like Google and Facebook will not monopolies the usage of these data. This is the dream of decentralization. The DxChain Network is designed to serve as a data trading platform for users who want to sell their data. Big data and machine learning computation is intended to make the use of data easier and more flexible.

DxChain Token Storage Key Points

DxChain Network Design Principle & Architectur

DxChain Token architecture of DxChain Network is adapted from the IPFS[11], Hadoop HDFS[22], GFS[31], FileCoin[12], IOTA[15], IoTeX[23], Plasma[21], TrueBit[20], morpheo[26] and Golem[9]. The entire system is designed based on the principle of incentivisation, which means that miners can maximise the utilisation of unused storage resources and facilitate decentralised big data computations with lower costs and much conveniences. The following section will describe the architecture of the DxChain Network. The chains-on-chain design, storage and computing with consensus protocol as well as the incentive mechanism will be explained in the subsequent sections.

DxChain Network Architecture Overview

DxChain Network provides decentralized big data and machine learning computation with the support of decentralized data storage. To achieve this complex project, the DxChain team is designing a specific chains-on-chain structure— which manages the master chain, storage chain and computation chain, to reach the consensus and to provide the incentive mechanism in a Byzantine environment. A peer-to-peer storage network, such as Inter Planetary File System (IPFS)[11], Swarm and Storj, provides a flexible and extensible file system where the data-frame and schema can be build. The storage chain is built on top of the storage data model, in which Proof of Spacetime (PoSt)[24] validates whether the storage provider really stores the files.

DxChain Network will start with Hadoop, the industry-proven big data platform, as its computation engine. The Hadoop running elements, such as the job tracker, task tracker and workers, communicate with one another through using a computational chain to synchronize running jobs. With two consensus mechanisms: verification game and Provable Data Computation (PDC), this chain would incentivize nodes that provide computation power

Chains-on-Chain Structure

DxChain Token team is designing the three-chain structure with two unique properties: 1) master and side chains structure, 2) immutable master chain and elastic side chains. Property 1 splits the chains according to their functions. Property 2 solves the problems of scalability, throughput and latency of the blockchain. The master chain is in charge of maintaining transactions. Based on experience from Bitcoin and Ethereum, this master chain is kept immutable. The side chains in the DxChain Network are in charge of storage and computation. These two functions are time-bounded, so that the blocks do not need to indefinitely store expired data. The DxChain team is designing a chain shortening algorithm which could remove unused data to save valuable block space.

Computing

Most of the popular blockchains are used for financial activity transactions, so their computations are simply checking transactional records on the chains; this type of computation does not require a lot of resources. However, the computations running on the DxChain Network are intended to support more general-purpose processing, such as database query and MapReduce work. Bitcoin uses blockchain to store all its transaction records to achieve consensus in the network and this consensus needs more than half of the active nodes to agree. It is impossible to store all computation states in a blockchain to ensure computation consensus; therefore, the DxChain team uses two mechanisms to ensure the correctness of the computations: verification game algorithm and Provable Data Computation (PDC)

Design Overview

DxChain Token master chain is similar to that of Bitcoin and Ethereum— it stores the ledger and asset information such as state, transaction and receipt, as well as the smart contracts. The master chain is good for storing small pieces of information since it is immutable. In order to support the complex data structure and computing information, the DxChain team proposes two side chains

Data Side Chain (DSC)— it is built upon a P2P distributed file storage system and stores the non-assets information.

Computing Side Chain (CSC)— unlike the hash mining (PoW) in Bitcoin, it is designed for useful work to solve real business problems and supports the specific computing task on the DxChain Virtual Machine (DVM)

DxChain Token computing unit can read data from the DSC and also write the result back to the DSC. After one job finishes, the final state, related cost and corresponding incentives are stored on the master chain via smart contract. The intermediate states and task-level transaction information are kept in either the DSC or CSC. With the smart contract across the master and side chains, the entire system can keep a low cost on the master chain, as well as high efficiency computing and data storage on the side chains.
