Overview

• Modified Implementation and Development method of Contract
• Improvement, Stablization, and Functional Integration of the consensus algorithm
• Changes in Network Connection method and Node Configuration

Branch & Genesis

• Modified Branch Chain specification.
• Implemented to setup and execute multiple contracts for each Branch Chain.
• Added Genesis Builder.

Consensus

• Improved stability of the consensus algorithm for master node (Validator).

— Exception handling.

— Improved stability of the PBFT algorithm & memory usage.

• Integrated the PBFT consensus algorithm with the general node module.

— Working the consensus process with profile configurations.

Contract

• OSGi framework integration in contract

— Contract call in OSGi Bundle

— Added the contract execution logic

• Rebuilt Stem contract
• Changed Contract Test process

Node/Network

• Implemented block, transaction request and response parallelism.

— Asynchronous broadcast and synchronization requests/responses

• Implemented SyncManager.

— CatchUp Sync

— Propagable block size limits

• Changed to organize the node network for each branch.
• Implemented Health check for closest peers.
• Refactored the network and peer package.
• Added node and network test code.

— Created a node test for each role.

— Created a node discovery test.

— Created a Node network configuration and block/transaction propagation test.

— Test after creating and deploying a docker-compose.yml for node network testing local and test server

Test/Infrastructure

• Setup an additional internal infrastructure.

— Intel Xeon CPU, GTX GPU system for testing.

• Tests for the consensus algorithm

— Tested 21 validator nodes for algorithm stability.

• Tests for block broadcasting

— Tested 100 nodes for broadcasting
