Elastos Bi-Weekly Update – 19 July 2019


While founders Rong Chen and Feng Han both spoke at events in China, the last two weeks have brought significant progress for the core teams, including adding ETH Sidechain to Private Net, preparing for the upcoming launch of Elastos Academy, and the current participation at a major hackathon in Beijing.

Elastos is also pleased to announce that later this year, we will be hosting booths at both Consensus Asia in Singapore and the AI and Blockchain Summit in Malta. 

Let’s recap. 

Technical Dynamics

* Now supports compiling and running on Android/standard Java platforms;
* Added Java API interface annotations to implement API interface documentation;
* Improved the ReadMe document, mainly added instructions for using the API interface;

– Hive Swift SDK:
* Improved API interface and implementation according to problems in the implementation process;
* Supplement Swift API interface documentation comments to support interface document generation;
* Updated the README document, mainly adding instructions for using the API interface;
* Optimized supplemental interface test cases;
* Hive Swift SDK can Now support iOS/MacOS platforms;
* Added CI verification for MacOS platform

– Hive Native SDK:
* Streamlined Hive Native Repositories, removed unnecessary dependencies and resources and files needed for Android/iOS cross-compilation;

– DID Java version of DIDStore development is completed, and the implementation of the chain docking has started;
– DID Native version of DIDStore is under development;

– Continued to strengthen test case validation for offline messaging features;
– Corrected some hyperlink location errors in the Readme document;
– Because offline message test cases run longer, API test adds parameters to select whether to run offline message use cases;
– Added CI verification based on MacOS platform for Carrier Swift SDK (originally only supported for CI verification on iOS platform);

Main Chain
– CR01 Milestone Sprint02 completed, completed CRC commission registration and voting related functions;
– Sprint03 has started to handle some optimization, productization and internal quality enhancement work;

Ethereum Compatible Sidechain
– The test group begins to prepare for the ETH SIDECHAIN pre-line test;
– Tested trading pool exceptions, modified cross-chain recharge to overflow the trading pool, added iterators to handle start-aware spv transactions;
– Determined the processing scheme when the new node is added to load a large number of mainline recharge transactions, causing the local transaction pool to be too large: first store these transactions persistently, and then process them one by one after the synchronization is completed;
– New geth recharge cash withdrawal feature, as well as oracle interface test, add bulk trading stress test;
– Conducted the local private chain TPS test, the current test result is about 400 transactions per second;
– Research desktop wallet that can be used in Ethereum compatible sidechains;
– Improved hackathon marathon Ethereum related documents and use several wallets to try to call the contract.

Private Net
