DREP 2019 Annual Report | Technology and Product Develop Simultaneously, DREP Builds International Ecology, Interprets How Does Blockchain Empower Business

Preface: 2019 was a time of change and a vital year for public chains to move from theory to application. The battle on commercial application among public chains started. Whether the public chain technology can support large-scale practical application became the most crucial competitiveness in this battle.

As an early practitioner in who is committed to creating “connectors” and “tooklits” of blockchain technology, DREP forged ahead in “blockchain+”and communicate with 100+ companies at home and abroad to realize technology docking. In 2019, DREP delivered impressive results in all aspects including technology implementation and ecological construction.

Technology and Product

As of December 2019, DREP has made significant progress in product technology and technical services and released 4 Testnets; also, there are total of 1,626 tests submitted on GitHub, including 3,847 updates and 1,226 completed tests; Based on the current needs of the blockchain industry, DREP has launched products such as DREP client, DREP gamification tool (DREP MINING), DREP cross-chain tool (DREP Bridge), etc.; As a “connector” and “toolkit” on blockchain, DREP provides blockchain technology solutions for various industries on the basis of blockchain technology products, helping companies achieve rapid blockchain development; Welcome more companies and developers join us to deliver an in-depth communication in technology and products.

After 4 iterations of Testnets, DREP pre-Mainnet Plank has been launched and under Mainnet test:

1. Completed Mainnet architecture, realized main network data synchronization and DREP TOKEN transaction function, supported DAPP or enterprises to develop their own blockchain systems based on DREP;

2. Improved traditional PBFT consensus mechanism, introduced PBFT based on multi-signature, combined the advantages of DPOS consensus mechanism to improve the efficiency of the DREP chain;

3. Improved smart contracts compatible with EVM and WASM

4. Completed the development of homogeneous and heterogeneous cross-chain technologies, formed a multi-level and three-dimensional user reputation list;

5. Launched more methods of DREP Staking, enhanced Staking system;

6. Completed the development of data cluster, supported the building of any alliance chain;

DREP helped enterprises deploy blockchain and reduced the technical barriers to entry blockchain industry.

Completed the technical development of DREP smart pipeline. The DREP Smart Pipeline is a “pipeline” for data transmission and for transferring data between the blockchain virtual machine and external applications. The blockchain client transmits real-time data to an external application via the Smart Pipeline, and the external application executes the result before transmitting the data back to the blockchain client in real-time through the pipeline. Smart Pipelines can be inserted into every step of the process where necessary to improve the execution efficiency.

Compared with Smart Contract, Smart Pipeline Has Advantages:

· “Smarter”: After the Smart Pipeline is deployed on-chain, its execution can be automatically triggered according to pre-specified conditions. In comparison with Smart Contracts, the Smart Pipeline will be able to handle more complex conditions and its execution process will be much more difficult to interfere with, thus being more conducive to the execution of complex transactions.

· Zero Gas Consumption: When an application using Smart Pipelines is executed, no gas is required as compared to Smart Contracts. However, zero gas consumption does not mean it encourages non efficient use of resources as all Smart Pipeline codes are required to be open sourced and will be supervised. Moreover, the computing resources that the Smart Pipeline consumes is not part of the corresponding sub-chain, but to be provided by the owner of the Smart Pipeline source code. Thus, even if there is a loophole in the above arrangement, it will not affect the performance of the corresponding sub-chain.

· No Language Limitations in Programming Coding: The Smart Pipeline technology uses the WASM virtual machine to execute transactions. Users can write codes in different programming languages and before compiling them into the WASM bytecode. As WASM continues to evolve over time, more languages will be supported, and the code efficiency will also be improved without affecting execution on the blockchain.

· Meeting the Needs of Complex Applications: Smart Pipeline applications are not limited by gas and enables blockchain to support more complex applications. Blockchains that adopted the Smart Pipeline technology are still able to interact with other applications or services, meeting the requirements of large and complex applications, thereby allowing for the development of applications which are not supported by existing blockchains

1. Through DREP SDK, DREP ID achieved decentralized login which has the advantages of third- party login and autonomous identity. It also supported the login of a large number of applications and controled the information transferred, achieving complete function of DREP DID;

2. Upgraded DREP SDK function, packaged SDK in various vertical industries, helped developers or enterprises quickly implement blockchain development.

DREP DID Ease of use and Interoperability:

· DREP ID supports multi-asset payment and exchange through the DREP Client application, giving users access to a convenient one-stop account management. In addition, binding different platform addresses to DREP ID allows cross-platform transfer by way of cross-chain interoperation.

· Such functionality is not just confined to blockchain. For traditional/centralized platforms within the DREP network, cross-platform management such as asset and data integration, encryption of information, etc. is also available through DREP ID without any interference on the existing numerical systems, loyalty point system, economic system or other aspects of the original platform, thereby forming an interconnected decentralized ecosystem.

· This allows DREP ID to support cross-chain DApps, allowing DApp developers and users to transfer mainstream currencies freely without suffering from infrastructure restrictions, and freely trade tokens on Decentralized Exchanges. As a result, the user experience would be improved, user bases would be expanded while reducing unwanted duplications in developments.

1. In March, DREP PC wallet launched, user guide released

2. In September, DREP mobile client 1.0.0 launched, realizing two-way swap function

3. In October, DREP mobile client 1.2.0 launched, adding TESTNET Coin and other functions (Source address is the same as 1.0.0)

DREP Client integrates asset management, identity management, application development, traffic portal, and other value-added services in DREP’s ecosystem. Users can store, manage and use a variety of digital assets through DREP Client. An easy-to-use SDK is also provided for developers and enterprises. Users can connect with various public blockchains including DREP Chain through the SDK.

1. Launched multi-chain and multi-currency asset management to provide users with digital assets services on storage, management and earning;

2. Completed the development of gamification tools, with functions such as creating economic models, providing asset consumption scenarios, and implementing user customized operations;

3. Open traffic entrance, users can obtain independent and valuable digital identities, DREP client protects user data security, ownership and related benefits;

4. Enhanced security and privacy protection, introduced zero-knowledge proof, and enhanced ease of use and interoperability.

As a cross-ecology and cross-platform asset management tool, DREP client provides enterprises with the service of quickly deploying wallet.

DREP Gamification Tool is a toolkit based on DREP SDK. Developers will be able to create economic models, provide asset consumption scenarios, and enable user-defined operations. With the objective of greatly enhancing the token economic system, DREP Gamification Tool is secure, decentralized, has customizable game elements and allows easy integration. Based on DREP Gamification Tool, DREP successfully developed the first blockchain miner parkour game — DREP MINING, integrating attributed of multi-currency payment SDK, hodl & mining, lock & earn, etc.

Main functions of DREP Gamification Tool:

1. Multi-currency Payment SDK

2. Digital Asset Consumption Scenario

3. Deflationary Economic Model

4. Viral Marketing and User Acquisition Tool

DREP Bridge is a proprietary cross-chain digital asset exchange and trading tool developed by DREP. DREP Bridge allows fast, convenient and secure token swap across different public chains.

Isomorphic Cross-chain Mechanism

DREP Isomorphic cross-chain is implemented by using smart contracts to achieve bi-directional locking. To perform a cross-chain transfer, the digital asset on the main chain will be locked, while the equivalent assets on the sub-chain will be unlocked. Conversely, when the related assets in the sub-chain are locked, the locked equivalent assets on the main chain will be unlocked.

Heterogeneous Cross-chain Mechanism

DREP Bridge heterogeneous cross-chain is made possible with the additional role, the ‘bridge.’ Based on two-way locking, an extra verification will be done to enable heterogeneous cross-chain operations.

DREP introduced zero-knowledge proof as a verifiable credential of user privacy information, ensure user data security. With DREP’s DID technology and DREP Client, users only need to maintain a single DREP DID private key, to access and manage multiple types of digital assets (e.g. BTC, ETH, etc.). A verifiable credential D is issued by a trusted third party DID_X to DID_Y. DID_Y’s verifiable credential D, which DID_Z wishes to verify, contains information that is irrelevant to the verification needs, while DID_Y wishes to conceal the irrelevant information from DID_Z. DID_Y can negotiate with DID_Z to verify the necessary information of interest via zero- knowledge proof such that his privacy is protected.

Based on the pain points in industry and blockchain application scenarios, DREP created innovative and easy to use solutions to help enterprises realize “blockchain +” quickly and use technological innovation to lead new industry standards. The solutions provided by DREP include: Supply chain finance, financial real estate, traceability confirmation, smart manufacturing, smart big data, digital integration, precision marketing, smart government affairs, etc.
