BP Voting

New features

1. add smart contract support for a continuous & never-ending BP election process, which tightly impacts the underlying super node election and operation. Voters who vote for the elected BP candidates will get rewarded daily and the source of rewards come out of WICC inflation mechanism that continuously generate 0.2 WICC coins within every new block added onto the blockchain.

2. allow any user to issue 4-char long WRC30 assets

3. provide asset icon URL setting method setasseticon onto 0-800 system contract

Changes

1. Asset state structure augmented with icon_url field to allow asset issuer to specify its ICON URL info. This change requires a reindexing of the blockchain states.

Non-changes

1. All existing RPC methods remain the same, hence not affecting existing apps utilizing those RPC methods

Changes:

• add getfinblockcount RPC method that does not cause node blocking (due to internal thread lock usage) like getinfo does. It returns finblock_height, the same as shown in getinfo. Service providers like Crypto Exchanges can use it to determine transaction finalization status.

Major update to v3.1.0.*

• fixed memory leak in pBFT connection maintenance implementation
• improved log level for pbft and mempool Tx messages

Minor update to v3.2.0.1

• made compilation compatible for Ubuntu 16.04 LTS for its missing libevent_global_shutdown function support

Changes:

• fixed a WASM asset class function bug that only arises in special cases with extremely large number input.

Major new releases in v3

• WASM Smart Contract VM Engine
• DPoS + pBFT (max 2 blocks or 6-sec Transaction finalization)
• CDP: Multi-asset collateral (w/ monthly interest-to-debt auto conversion)
• DEX: SaaS ready (DEX #1,#2,... registration and operation support)
• UTXO Transaction addition
• DeGov (SysParams, Cross-chain etc processes)

Major Milestone Code Names

• v1: Dragon
• v2: Ascend
• v3: Tiger
• v4: BigLeap

• implemented internal lock optimization to achieve better mining and data synchronization
• fixed CDP forced liquidation bug
• fixed RPC json field null type bug

• Fix bugs associated with fork rollback validation process
• Remove unnecessary block creation during non-miner-slot to reduce CPU usage

For speed synchronization, the core team has uploaded the blocks data onto a cloud storage: https://waykichain.oss-cn-shenzhen.aliyuncs.com/mainnet/blocks/wicc-blocks-20191028.tar.gz

The steps to use the blocks provided from the above link:

1. $wget https://waykichain.oss-cn-shenzhen.aliyuncs.com/mainnet/blocks/wicc-blocks-20191028.tar.gz
2. $tar xzvf wicc-blocks-20191028.tar.gz
3. $rm -rf ~/.WaykiChain/main/blocks
4. $mv blocks ~/.WaykiChain/main/

(P.S. You shall modify the path to blocks folder according to your own settings for the Node program)

• Fix delegate calculation fork chain update bug
• Add CDP interest receipt

This release fixes bugs carried from the initial release and has been used for running the current v1.0 mainnet network (v1.3.0.1-87778bb-release-linux (2019-08-16 14:01:38 +0800)
