DID
– Handled mnemonic errors caused by inconsistencies in multilingual Unicode normalize form

– The solution to delete the txid dependency is determined, the Native SDK has been updated and verified, and Java and Swift will be modified later
– Optimized the implementation and storage of DID related metadata in Java SDK
– In response to Trinity’s needs, supported the creation of verifiable expression documents without credentials
– Fixed some bugs found in testing and application development

Hive
– Designed and discussed Hive++ docking authorization and access control model
– According to the interface document provided by the Hive++ service, started to upload files to the Hive++ storage service node by HiveSDK
– Implemented DID login to the backend Hive++ service node in Hive SDK
– Sign-in authentication process based on front-end DID identity for Hive++ services
– Evaluated the implementation of Python C-binding and started to implement the Python DID interface based on the DID Native SDK

Carrier
– Released Carrier Swift SDK-v5.6.0 version
– Implemented and verified the SendMessageWithReceipt() interface in Swift SDK
– Optimized the SendFriendMessage compatible interface, which can solve the boundary scenario where the peer Friend is in the online->offline switch when sending a message
– Implemented support in Carrier Android/Swift/Native SDK where Carrier nodeid is generated by the upper application to input a predefined Secret Key

– In order to solve the problem that the UI thread is blocked by calling the Filetransfer::writeData() interface in the elastOS application, the synchronous call on the Native Platform (Android/Swift) in the Carrier Plugin is modified to be an asynchronous call.
– Started to implement WebRTC iOS SDK version
– Upgraded Carrier Native SDK dependent library flatcc to 0.6.0 to solve the compilation problem that occurred when using gcc-9 and above compilers in Linux environment
– Solved the problem of Carrier Native SDK’s memory leakage caused by internal modules referencing each other
– Assisted the community development team to optimize and improve the UI presentation of the front-end Feeds dApp
– Assisted the community development team to complete the conversion of the back-end Feeds Service from the original jsonRPC data exchange format to the msgpack data exchange format that supports binary data
