Greetings from Team YGGDRASH.

The YGGDRASH Sprint 0.2.0 is here!

Details of the updates can be found on Github :

yggdrash/yggdrash

Overview

• Prepared to run various consensus modules through consensus modularization.
• Integrated the OSGi contract platform and implemented modified network governance through consensus.
• Enhanced the block synchronization process and tested the propagation of blocks and transactions between the validator node network and the general node network.

Consensus

• Multiple Branch Chains & consensuses support in the Validator module.

— Changed the working process based on the thread.

— Changed the configuration to operate multiple services.

• Integration of the Node module and the Validator module

— Changed the Node module to run consensus functions.

• Improved stability of the Validator module.

— Improved stability of memory usage & exception handling.

Contract

• Version Control Contract

— Version Upgrade in Contract

— Proposer Version Upgrade, Validators can vote on Versions (*revoke, agree)

— Upgrade state view

• OSGi Contract Integration to YGGDRASH Platform

— Branch Contract information installed through OSGi Contract

• BranchStore permissions change in a contract

— Save and load Validator set

• Change the contract loading sequence

— Load and validate in a declared order in the branch

• Store and load Branch Contracts into/from the Branch store

— Prepare for changes such as contract version-up

• Split the Contract Module

Node/Network

• Change the block and transaction propagation method (synchronized to asynchronized)
• Implement to join the network after full block synchronization at the node startup
• Implement the block synchronization manager

— Enhanced CatchupSync

— CatchUp request while ping communication and block is broadcasted

— Block request and synchronization in the maximum block synchronizable range

• Implement the transaction indexer

— The transactions contained in the block are indexed and stored in the database by events when chaining block to a blockchain

— Indexing transactions by the properties of transaction

— Indexing for 2-depths transactions

• Passing blocks and transactions using a delivery node between the validator network and the general node network
• Execute a random node stopping test during block and transaction propagation in random nodes
• Upgrade dependency major library
• Upgrade YGGDRASH Explorer For Main-net
