Bug fix in difficulty adjustment algo, i.e., "MagiQuantumWave"; the bug manifests as an improper data conversion when carrying out a time-domain average because of the trival time difference between blocks.

This release schedules a hard fork at block #1606950 as a solution to the current mining issue that miners cannot mine blocks. v1.4.5.1 is compatible with the prior block chain.

  • The PoW / PoS block generation rule is disabled;

  • Difficulty adjustment algo switches back to MQW at #1606948;

  • Block drift time is limited within 5 min;

  • Remove IRC and add DNS seeds.

Quick startup I (without touching the block-chain):

  1. Backup wallet.dat;
  2. Launch the new wallet.

Quick startup II (replacing the block-chain):

  1. Backup wallet.dat;
  2. Download block-chain data from here: http://m-core.org/bin/block-chain;
  3. Delete all of the contents under the .magi (unix-like system) or Magi (OS X or Windows) folder, except for wallet.dat and magi.conf;
  4. Unzip the file and copy the folders under "m-block-chain" into the .magi (unix-like system) or Magi (OS X or Windows) folder;
  5. Launch the new wallet.

This release solves the recent blockchain forking issue, including the follow changes:

  • Synchronizing checkpoint & master server introduced; this is to remove constantly checking on the misbehaving and IP banning, along with the error "block with too little proof-of-stake or proof-of-work". The checkpoint master server and keys remain to be used from now on; they are likely to be removed in the future;

  • Implemented a block generation rule: PoW / PoS blocks are mined / minted by following a pattern: 1) at least two PoS blocks minted between two consecutive PoW blocks, or PoW blocks generated every 10 minutes; 2) at least one PoW block is found in five consecutive PoS blocks, or PoS blocks generated every 3 minutes;

  • Difficulty adjustment will be changed to four-block exponential moving average. When there is violation in aforementioned PoW / PoS generation rule, the difficulty remains unchanged.

The following hard forks are scheduled to implement the changes:

  • block 1481500: PoW / PoS block generation rule, and also exit point of the maintenance mode;
  • block 1482000: difficulty adjustment algorithm switch.

Nodes:

  • 104.128.225.215
  • 45.35.251.73

This release is a temporary fix to the current blockchain issue in MAGI; this is done by taking 104.128.225.215 as a trust node. Following settings in magi.conf are highly recommended. The second stage of fixing the issue is currently carried out. Refer to "http://m-core.org/blog/" for news and final fix to the issue.

  • Changed database for storing transaction and block indices from Berkeley DB to LevelDB;
  • Enabled block hash storing in storage and loaded directly from disk;
  • Fixed "Checkpoint is too old" warning;
  • PoS stake splitting and combining features, which can be set by stakesplitthreshold=VALUE and stakecombinethreshold VALUE in magi.conf, or by RPC commands: setstakesplitthreshold and setstakecombinethreshold; RPC commands getstakesplitthreshold and getstakecombinethreshold to show their current values;
  • Added price information on Qt overviewpage;
  • Qt wallet logo change and GUI improvements;
  • Merge pull request of adding total balance in "Transactions" page by lightsplasher;

Upgrading procedure:

  • In general:
    1. Backup wallet.dat;
    2. Delete everything under the Magi or .magi folder except wallet.dat;
    3. Download block chain from here http://coinmagi.org/bin/block-chain/ and unzip the file;
    4. Put all of the contents under the folder m-blockchain into Magi or .magi;
    5. Launch the new wallet.
  • Windows:
    1. Backup wallet.dat;
    2. Launch the installer;
    3. Choose the option you want to migrate the block-chain; the installer will always move the original Magi folder to something like Magi-BACKUP-*;
    4. Follow on-screen prompts to install.
