1 year no update for XMG. Angry

That does sound embarrassed; I guess I have more time pulled out from work already.

Feel free to shoot me a PM if you need help setting up the automatic update checking with the official site. I'm also not opposed to hosting the update text file in the interim for you guys if that will help.

Also, I was planning on adding the following as a pull request some time ago, but life shifted a bit for me and I haven't found the time to do work on it. Here's a link to PayCoin's (sort of hack-y) solution to the "Checkpoint is too old" problem: https://github.com/PaycoinFoundation/paycoin/pull/33. It basically just took out the check for checkpoint age, which is sort of a grey area... but it would definitely calm down the panic about the error popping up in the wallet.
Thanks amigo! Appriciate your respons.
Think Joe also likes this!
I'am very proud to see that our Magi community is still growing and awesome!

111magic,
oh, I've understood. At first I deside that Magicoin is under DDOS attack. My life is cumputer reality. I am not watching the news and now I know.
Haha ok. Good thing you asked than!  Smiley

It's very sad! I still remember the attacks in France! Cry

Can you talk more detail about of this? I learn XMG only for a month and I don't know of all the history of this great coin.
Thanks amigo you are very welcome.
What I mean is that a few months ago the Magi logo had the colors of France. Today the logo has the colors of Belgium. As symbol that our thoughts are with them.

Hi men! Do somebody have positive experience at scheduled on idle mining on WinXp x86?
I have some scheduled at idle miners on win 7 x64 and they works.
But all my tries to schedule idle mining on WinXP (I have at least one i5 pc on Win XP) failed.
Somebody?
Sorry I don't have experience with idle mining with WinXP x86. Maybe somebody else.

Thoughts are with the people from Belgium!

This project has a great and active community. I believe great things will come too in the long term...

Thanks for the nice words and welcome in our awesome Magi community!

# Piece of info
Magi Cheat Sheet v1: http://coinmagi.org/files/misc/magi-cheat-sheet-v1.pdf

# Brief summary

  • Implement a filter for the difficulty data and stabilizing yielded block rewards; anticipation is improved accuracy of the block-rewarding (MagiReward) system in responding to the actual network hashrate;
  • Introduce a CPU miner targeting at reducing hash rate (https://github.com/magi-project/m-cpuminer-legacy) which is much more meaningful for magi in comparison with any other coins;
  • Adapt a close limitation of the PoS stake weight which disables potential PoS attack via accumulating significant amount of coins or offline stake time;
  • Other miscellaneous updates.

Huge amount of energies consumed in the cryptocurrency has been a big issue, which is totally opposite to the global efforts in saving energy. This issue should be resolved sooner or later in order to advance the cryptocurrency any further. As one of the possible solutions, that's the reason we have PoS. However, the pure PoS mode would never give rise to decentralization. Any approaches are vain if decentralization cannot be maintained, unless one agrees with a coin with limited time of mining or with total premining, or the such likes. The PoW should be remained in order to distribute coins into a broad audience over time.

The basic rule of dealing with the energy concern is to involve a "braking" mechanism in coin design. Such a rule exists in every piece of things in nature: why earth/electrons should circle the sun/nucleus without collapsing or departure? or just imagine a vehicle without brakes. Bitcoin or litecoin does not put actual limits in the rewards, or that simply not functioning properly. That's where magi plugs in.  

What do we need to save energy?

On the whole, mining should be encouraged at a lower hashrate level.

# MagiReward-V2

The issue to be solved in this upgrade is the removal of the vague dependence of block rewards on the difficulty, due to the fluctuating nature of block time. A basic consideration is applying a filter to smooth out the difficulty data. Details are as follows.



# Necessary to adjust miner efficiency?

A direct consequence of the above implementation is the well-shaped block rewards in which big rewards due to network fluctuation are totally avoided. The following figures disclose the real situation most likely:



Mining at a network hashrate of 22 Mh/s results in 50 XMG/block, whilst hashrate increases to 36 Mh/s like mining the air.

Who shall mine nothing?

Provided that I have a miner with hash rate of 1000 kh/s; I would have big concern of yielding nothing at its full speed, but I don't care throwing 10kh/s at nothing. The reality behind this scene will be a different story; at the time by which the exit of miners will pull the block reward back to some numbers, one is able to mine something by then. Reducing hash rate does sound the right action in this incident.

Attenuating hashrate of miners in mining bitcoins is very unusual or pointless, since the higher the hash rate, the greater the bitcoin amount mined. Except this sole "advantage", there are dozens of facts people should be aware of that increasing hash rate comes along the wrong direction: 1) running a PC miner is totally incompetent since every single person in the world would like to sharpen their miners with high hashrate; 2) running 100% CPU usage miners is impractical in most of situations even if one can do so; 3) mobile devices are incompetent under this scene.

It will be wise to run a hashrate-depressed miner under the improved MagiReward system. Technically by doing so it's possible to run miners everywhere.

# m-cpuminer-legacy

We are "joking" the miner, but this is for real that you'll need it; running it in VPS without incurring limitation imposed by vendors? working computers / school's super computer? Cheesy Here is the option.

https://github.com/magi-project/m-cpuminer-legacy

Code:
minerdlegacy -o stratum+tcp://pool_url:pool_port -u pool_user.worker -p password -t thread_numbers -e cpu_efficiency

This is none different from the regular miner, except that an option "-e cpu_efficiency" is added, where cpu_efficiency is a number between 1 - 100, for example, 50 representing for 50% of CPU usage. A few instances:

-e 75 -->
-e 50 -->
-e 25 -->
-e 1   -->

Given 10~30% CPU usage, the miner is more like a regular program. Please notice that neither I nor the magi team shall be responsible for any consequence because you run the miner in your working computers or school super computer.

# PoS-II-V2

What we have done in this upgrade is adding rigorous limitation on the amount of coins in one transaction for staking purpose, and reducing maximum staking time within one week. We don't expect impact on typical situation where one remains wallet online for PoS stake; the offline time should not exceed more than a week. We also recommend to keep 100 - 1000 XMG in one transaction for best results.

Again, magi implemented a braking mechanism which makes it more secure compared to any other PoS coins. To understand that, take a look at the basic PoS mining equation:

Code:
hashProofOfStake <= [Coin-age] x [Target]
[Coin-age] = [amount of coins] x [days in stake]
and,
Code:
[PoS-block-reward] = [Coin-age] x APR / [days in a year] 

Apparently [Coin-age] is a paramount quantity for PoS, which is the driving force for people to stake with as many coins/days as possible. The major weakness in this mode is a possibility of attacking the network by mining a number of blocks ahead of other PoS miners, which can be done via accumulating significant [Coin-age] by

1) having significant amount of coins, which is technically difficult to be achieved in PPC, but rather easy in a freshly created coin;
2) accumulating significant amount of offline days of coins which shall not undergo any transactions before staking, which is a rather feasible approach.  

Approaches to resolve the above situation have been proposed, mostly by manipulating the staking days. In contrast to PPC's linearly increasing coin age with time, BC and RDD are two example coins with efforts towards this, but neither of them take care of both situations simultaneously. The BC's V2.0 takes the staking time out of the equation, i.e., [Coin-age] = [amount of coins], which does not solve the issue #1. It is also none organic that one cannot buy advantages from staking time using a cheap PC, in addition to simply buying coins. The growth rate of staking days over time is compromised in RDD if one stakes coins over a month; it should be noted that any desired attack can happen within a month staking time. In addition to the above point, one should be aware that the difference in the number of coins under stake should be emphasized too. The system should encourage one staking with more coins, but discourage greedy accumulations.

Magi's PoS-II?

Magi takes the following form for coin age:
Code:
[Coin-age] = [amount of coins] x M(coins, days)
where M(coins, days) is a function of the amount of coins, and the days under stake. [Coin-age] is also the so called stake weight. The best description of M is shown below:



It's rather empirical to determine the best value of stake days. I am rather taking time to sit down and figure, with a basic rule in mind, to limit it within a week. Let's see how it solves the PoS issues:

1) one holding more than 3000 XMG does not result any good in the stake weight; for staking over 25,000 XMG is like staking with nothing;
2) the maximum offline stake time is four days, beyond which staking weight starts to drop; it's unlikely to accumulate infinite staking time.

A side advantage of the PoS-II is that significant amount of offline time is not allowed. There is no advantage of gaining coin age for offline more than 4 days. For any online stake holders, the block time will be refreshed upon finding blocks. The stake weight (coin-age) nearly increases proportional to the amount of coins when coins in one transaction are between 100 and 1000 XMG.

# Misc updates

1) PoS status update in wallet GUI; please be aware that "expected time to earn reward" is only an estimate.  

2) Correction of the money supply shown in API calls: getinfo by reducing 720,000 XMG, which was burned (https://bitcointalk.org/index.php?topic=735170.msg9900074#msg9900074).

3) Added API calls:

That does sound embarrassed; I guess I have more time pulled out from work already.

Is there coming an update of the wallet?
Now it's a big problem to send bigger amounts (20-50k) of XMG after one month of staking.
This results in errors and you have to send XMG in smaller parts.
Also when you send XMG after longer staking you must pay 100 times the normal fee, why?
Yes there will be an update.
Talked with our developer yesterday.
Magi-team will post the launch date as we receive green light from Joe!

If you try again it should be ok now!
1855  Alternate cryptocurrencies / Announcements (Altcoins) / Re: Wallet on: March 18, 2016, 06:07:09 PM

He amigo,

Magi had a meeting yesterday. Joe will work on a new wallet with more improvements.
It will take time. (because of his new Job and moving to another place)
In the mean time there will be a temporary new wallet what will be faster.
Hope that one will not take much time for launching.


OK. Two questions:
- when this new it will be delivered?
- whether new wallet (doesn't matter temporary or not) will deliver all binaries compiled?

please answer my two questions



1) Joe did not gave a delivery date yet.
He told us hè will develop it but has not much free time because of new job and moving to another house/city. So we have to give him some time.
2) Think yes. For sure Joe noticed your request and hè will deliver those or respond on it.


[/quote]

Thanks for the info.
But it is a little scary. One developer with no time.
[/quote]

Do you know now any date the all wallet binaries will be compiled and available from XMG official site?

I sent Joe a message. Waiting for his answer.
