Preface: 2021 is a year full of uncertainties and also a year with opportunities and risks. But what remains unchanged is that users never stop pursuing a safe, high-efficient and low-cost blockchain platform. During the first half of this year, DREP has followed the trend and built several ecological infrastructures, endowing cryptocurrency with new possibilities. After repeated tests and deep development, DREP 2.0 is ready to provide services to users with diverse needs.

In addition, DREP has also forged partnership with many leading exchanges to expand its service channel and held AMA in the DREP community to facilitate interaction and communication with users. It is excited to announce that DREP has made great achievements. In the first half of 2021, DREP delivered remarkable results in various perspectives including technology implementation and ecological construction.

Technology and Product

DREP 2.0, a decentralized credit-data middleware based on layer-2 facilities, has initiated an upgrade from frictionless blockchain toolkits to DeFi Credit Protocol and launched a series of products that could better serve the demand of the industry.

The first product released in the DREP 2.0 Product line, DREP Crossing is the ultimate solution to efficient and flexible cross-chain swap of multiple assets including NFTs. Moreover, DREP Credit Oracle & Credit Explorer characterizes both the traits of integration of users’ credit data and decentralized delegation. DREP Token, the primary approach for fee payment, fully captures the value of the entire credit-data network. DREP 2.0 is also committed to building a DeFi Credit Protocol, which will change the single method of credit enhancement in the DeFi field through over-collateralization and enhance the multidimensional credit investigation of DeFi user portraits. In terms of Cross-protocol Credit Granting and Credit Transfer, DREP Credit DID fully improve the accuracy and efficiency of the DeFi protocol, providing more flexible and seamless experience to users.

After months of dedication and endeavor towards DREP 2.0 product line, major progress that DREP team has made include:
· Established the framework of the distributed digital-identity system
· Provided the testing interface for DID calling
· Achieved the generation and transfer of verifiable credentials
· Optimized the Reputation System’s anti-attack function
· Conducted Beta test of the DREP Verifiable Whitelist
· Conducted Test of Optimistic Ethereum

DREP has completed the DREP 100:1 redenomination plan.

In DREP 2.0 product line, DREP Token plays a key role as the primary approach for fee payment and fully captures the value of the entire credit-data network. Considering this, DREP has conducted an upgrade plan for DREP Token and received supports from some leading exchanges such as Gate.io, Binance and AscendEX, all of which have completed DREP token redenomination and commenced trading for upgraded DREP.

Here are some key information :
· DREP trading pairs are DREP/BTC and DREP/USDT.
· DREP Token Swap will officially begin on 2021–03–05, ending on 2021–09–01.
· Total supply of DREP Token after the redenomination: 100,000,000
· Circulating supply of DREP Token after the redenomination: 39,900,000

The latest DREP token metrics information has been updated on CMC. DREP page on Binance has also updated DREP token metrics information. Users can obtain the latest DREP token metrics information on both websites.

DREP has officially achieved the first new product launch in DREP 2.0 product line: Crossing.network.

Aiming at the pain points in today’s NFT market and cross-chain asset swap, Crossing is the ultimate solution to NFT cross-chain swap & multi assets circulation. It is committed towards combining NFT cross-chain circulation + multi-asset trading to simplify its transfer process, expand the current NFT market, accelerate NFT valuation/pricing by providing the trading board function, and provide more convenience to all NFT lovers. It will be capable of solving almost all of the major pain points in the current industry, such as the cross-chain swap of multiple assets including NFTs.

Crossing is already live on Ethereum, Binance Smart Chain (BSC), Huobi Eco Chain (Heco Chain) and Gate-Chain. It is equipped with numerous advantages including multi-chain & assets support, lower gas fees, decentralized system, easy to enter, rich liquidity incentives, etc. It will also launch a unique NFT cross-chain swap function in the near future to explore more possibilities and value of cross-chain NFT circulation.

DREP concluded the best approach to NFT swap for Crossing is to map tokens according to the NFT assets. Instead of simply establishing a mapping relationship to achieve cross-chain swaps for NFTs, Crossing’s approach is applicable for both ERC-1155 and ERC-721 NFT types.This approach has removed the restrictions on NFT cross-chain swap and created greater value for the NFT market.

In the Q1-Q2 of 2021, DREP completed the developing and launching of DREP Credit, a stepping stone for DREP’s “Defi+NFT” mapping. DREP Credit’s launching is a great success, attracting more than 84,000 users in the first three days. Now the total amount of Credit users are more than 350,000, acting as a strong data source and community accelerator in DREP 2.0.

DREP Credit is a middleware system for building a fundamental database of multidimensional credit data network. DREP Credit is an important step in building DREP’s Defi Credit Protocol. The protocol will aim to create a brand new ecology after the redenomination of DERP tokens encircling implementation of DREP DID network, Cross-protocol Credit Granting and Credit Transfer, and future Verifiable White List.

DREP Credit uses API technology, in many ways can provide solutions in determining vital parameters such as variable interest rate, margin rate, commission rate, and clearing threshold. It will create a decentralized credit database, which is in line with further development of DeFi credit. Through the application of DREP Credit, all the above reflected credit profile forms an information pool or database for users further investing enhancement and transactions decisions. The openness and inclusiveness of DREP Credit entail the possibility for DREP to march into outer-cyberspace and realist fields. Moreover, the credit collected by DeFi users through the guidance of DREP Credit will be a key supporter of DeFi Credit Protocol in accumulating users’ historical transaction data, asset management, preference settings, and even Internet social behavior.

DREP Public Chain has gone through some significant updates in the fist half of 2021. We got to present our users the DREP public chain with more proficiency, stability and security.

DREP reconstructed its public chain code and improved reusability of the codes. We also fulfilled the first stage of the DREP reputation calculation model, increased the pledging limit of block nodes and optimized the generating nodes for block creation and upgraded node selection strategies, preventing node block forks. Apart from reconstruction of nodes, DREP enhanced the security of DREP Wallet. The wallets configured by block-generating-nodes will be closed by default and only be unlocked and begin generating blocks after the node has been initiated. The monitoring nodes no longer need to be configured with the default address to synchronize the block data. The unit test and node adjusting have also seen optimization. The team has been working on the design and development of the evaluation of nodes’ block generation quality and weights, to further enhance the stability of block generation.

Other improvements include:

· Optimization of the DOM structure
· Elimination of redundant P2P content
· A better adaption of DREP to EVM
· Optimization the efficiency of transaction packaging and avoid transaction congestion

Since 2021, DREP Explorer has been rather mature. The Explorer is steadily growing. The basic structure is quite solid. During the last 7 months, DREP continue to improved the query and the display interface of contract contents. The page size were compressed further to ensure fast access speed. Optimization of block display and diary outlining were under going.

The security of the DREP wallet has been enhanced, in which the wallets configured by block-generating-nodes will be closed by default and only be unlocked and begin generating blocks after the node has been initiated. Nodes’s block generation has been optimized with the node configuration process being simplified. With this improvement, the monitoring nodes no longer need to be configured with the default address to synchronize the block data. The DREP explorer continues to optimize block display and compress the page size to further improve access speed, deliver block query results to users and developers at a faster speed, and optimize the overall user experience.

Technology Application

The DREP DeFi Credit Protocol aims to create a brand-new ecology after the redenomination of DREP tokens. With DREP Crossing launched on Ethereum, BSC, Heco chain, Gate-Chain, Crossing effectively and innovatively reduces barriers in cross-chain swap and multiple assets circulation. Moreover, DREP Credit Oracle & Credit Explorer characterizes the integration of both users’ credit data and decentralized delegation.

DREP Credit, which is an interface application, shows great performance in determining important criterions such as variable interest rate, margin rate, commission rate, and clearing threshold. The effective accumulation of data provided by DREP Credit guarantee the fluent progress of the DREP Credit Protocol. With the development of DeFi credit and the protocol, users are willing to associate their own scattered addresses and IDs to obtain incentives and raise their credit ratings, which is bound to bring vibrance to the development of DREP Credit Protocol.

Nowadays, NFT can be applied to many types of scenarios such as games, virtual assets, artworks, collectibles and identity authentication, and can be purchased, sold, leased and auctioned on some trading platforms. DREP believe that NFTs will not be an Art-market bubble, but instead, a breaking opportunity for many fields in the future, such as asset and identity management.

In fact, DREP has started its exploration into the innovative application of NFT long before today’s trends — — the DREP gamification tool based on DREP SDK. While now in the roaring times of DeFi, NFT’s applicable situation be widely expanded, commercialization and gamification become the hottest trends. DREP have made NFT growth in both trends.

Firstly, DREP Crossing can support cross-chain swapping, herein the NFT holders can capture more value and promote the ecological exchange of NFT between chains, DREP’s Crossing is applicable for both ERC-1155 and ERC-721 NFT types. Therefore, token mapping is the best operable solution to enhance interoperability of NFTs. By mapping a new token as the alternative for the NFT asset through DREP Crossing, users will be able to flexibly swap and transfer their NFT upon approval.

Secondly, 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. When the token-wise value of NFT is fully developed. DREP’s Gamefi will plan to build a game rewards pool or devices pool in form of NFT for selling, displaying and gaming. More applications are on the road…

DREP has kept working on developing the DREP credit NFT assets delegation and transfer system to provide more trusting and convenient DeFi solutions for its community.With the increasing popularity of NFT, more and more NFT using scenarios have been dug out in terms of games, virtual assets, artworks, collectibles and identity authentication. Among which NFT artworks emerged with the most various forms and took up a huge amount of market transactions, however, the DREP team realized that the next trend should be “gamification finance” under the integration of DeFi + NFT.

Since the previous experience in blockchain game development and the strategic cooperation with multiple gaming incubators form a solid foundation, DREP has made efforts to improve the DREP Gamification Tool, which is already secure, decentralized, has customizable game elements and allows easy integration, into a more mature one.

Up until now, DREP is building a DeFi+NFT service network. By exploring GameFi Credit solutions, the team has proved the significance of NFT in data asset management and opened up more possibilities for NFT applications beyond its utilities as art work collectibles.

The DREP team has achieved the “financialization” of NFT through the DeFi protocol, and is committed to using NFT to generate more assets. DREP DeFi + NFT is constantly creating new sparks to achieve good synergy and solve many problems.
