To All,

We got an issue few days ago, and here I'd make quick overview:

1) I'm getting to a point for an internal test of the fix (tomorrow night); I appreciated those who have helped MAGI on this incident. In case one wish to test or review changes, you can come to Slack; find 111magic (coin_magi_xmg) / ex33s / me there.

This incident has been observed as being related to the Pow / PoS rule in combination with the fact that 2-hour future blocks allowed as in the original design. Addition to this, the new block rule disturbs the difficulty, and this feature of uncertainty seems yet to get around. In observation of the Pow / PoS rule actually not being a major factor fixing the prior chain forking issue, I'd go (temporarily to go permanent upon no upcoming concerns) disable it. In the meantime, we will do a reduction of time drift for the blocks.

2) We try to make a release of the fix within this week. My expectation is that the fix would be like changes implemented such a way that a hard fork is required. Chain downtime or rollback will be avoided as much as possible, and actually I don't see those are necessary. Except for a need of the hard fork to get mining back to normal, this incident seems no influence on things like sending / receiving. Let me know if I missed some thing.
 
Awesome Joe thanks for the info!💪

Hi all, just to give you an update:
Magi tests are good. Team will use some time to adjust small improvements. Magi would like to release a good hardfork better than a fast fix. Magi learned that in the past 3 years. Bear with Magi! 💪

m-wallet version v1.4.5.1

Hard fork will take place at block #1606950. See below for the details of hard fork.

Qt-Wallet and Daemon:

https://github.com/magi-project/magi/releases
http://m-core.org/download/
http://m-core.org/bin/m-wallet-1.4.5.1/

Source code: https://github.com/magi-project/magi/

Windows: http://m-core.org/bin/m-wallet-1.4.5.1/m-wallet-1.4.5.1-win.zip
Linux: http://m-core.org/bin/m-wallet-1.4.5.1/m-wallet-1.4.5.1-linux.tar.gz
Mac OS X: http://m-core.org/bin/m-wallet-1.4.5.1/m-wallet-1.4.5.1-osx.dmg
FreeBSD: http://m-core.org/bin/m-wallet-1.4.5.1/m-wallet-1.4.5.1-freebsd.tar.gz

Block chain: http://m-core.org/bin/block-chain/

v1.4.5.1
=============
This release schedules a hard fork at block #1606950 as a solution to the current mining issue that miners cannot mine blocks:

- 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.

Quick guide:

- Windows: unpack the files and run the wallet directly;
- Mac OS: unpack the files and copy to the Application folder, and then run the wallet directly;
- Linux: unpack the files and run the wallet directly.

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

0) Backup wallet.dat;
1) Launch the new wallet.

Quick startup II (replacing the block-chain):

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

Note to v1.4.5.1
---------------------
v1.4.5.1 is compatible with the current block chain.

Things explained..

Firstly, I admit what's going on isn't good to the situation, and I do see there are needs of further works to fulfill the purpose of the coin.

There is no rollback. I learned few requests about actions on the miners who mined (future) blocks that the generic miners can't mine, and for that, rollback is one of the approaches. However, taking into account the overall situation that time to time transactions are involved, especially exchanges, there will be more damage to the coin when we cease the chain or perform a rollback.

As explained shortly in previous post, what happens is associated with the PoW / PoS rule in combination with the fact that 2-hour future blocks allowed as in the original design. I do see in this rule weakness because of the PoW block generation capable of being on a 10-min pattern without the PoS blocks. The another feature of MAGI's network that is intentionally kept at low hash rate comes a likability that one with a reasonable amount hash can launch a future block attack, the chance of this is increased by a fact that generic users can't make valid blocks owing to the PoW / PoS rule; these blocks are supposed to reset the block time.

By overviewing the situation, I see there is a difficulty in maintaining low-hash rate network, as individuals can always acquire big hash rate. In contrast, advantage lies in a network with huge amount of hash that individuals can't compete with. Nevertheless, it's not our intention to compromise the purpose because of the weakness. The PoS is supposed to dilute such weakness; I'm seeing the merit of the PoW / PoS rule when used beautifully. We shall make efforts on this aspect.

Let us know any questions / suggestions.



👍👍👍👍👍 awesome work Joe!!

m-wallet version v1.4.5.3

v1.4.5.3
=============
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.

Qt-Wallet and Daemon:

https://github.com/magi-project/magi/releases
http://m-core.org/download/

Source code: https://github.com/magi-project/magi/

Windows: http://m-core.org/bin/m-wallet-1.4.5.3/m-wallet-1.4.5.3-win.zip
Linux: http://m-core.org/bin/m-wallet-1.4.5.3/m-wallet-1.4.5.3-linux.tar.gz
Mac OS X: http://m-core.org/bin/m-wallet-1.4.5.3/m-wallet-1.4.5.3-osx.zip
FreeBSD: http://m-core.org/bin/m-wallet-1.4.5.3/m-wallet-1.4.5.3-freebsd.tar.gz

Latest Block chain (1603558): http://m-core.org/bin/block-chain/


=============
Regarding this version: we have initial scheduled hard fork here: https://bitcointalk.org/index.php?topic=735170.msg27192013#msg27192013. We passed the fork point but stuck at 1606987; it was found improper data conversion that is used to deal with difficulty adjustment gets zero when handling small number; diff-adjust takes place using average over a time domain. Many blocks emitted between 1606950 - 1606987 causes tiny difference between their block time, that then hits on the bug.



Release new wallets!!!!
