[ANN] [XMG] MAGI | CPU mining | mPoW | mPoS | [MagiPay]

[digibob00]

I'm on Raspbian. The excute do not work. Nothing happens.

Please check out my GitHub page, https://github.com/feldenthorne/magi/tree/armv7l_official. You should be able to build the Qt wallet after entering the following:

Code:

sudo apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libssl-dev libdb5.1++-dev git
git clone https://github.com/feldenthorne/magi
cd magi
git checkout armv7l_official
qmake
make

I recently made some changes that should fix builds for the RPi2, so you should be good.

Edit: Just updated the binary release on GitHub, but you should probably build it yourself because it's always better to be more cautious than less.
And here's my GitHub pull request from the official repo for the wary: https://github.com/magi-project/magi/pull/5.

When I put qmake it says me that : Project MESSAGE: Building with UPNP support
Project MESSAGE: Building with IPv6 support
Project MESSAGE: FOUND host = armv7l
Project MESSAGE: Building with UPNP supportProject MESSAGE: Building with IPv6 supportProject MESSAGE: FOUND host = armv7lProject MESSAGE: Warning: unknown QT: widgets.

And when I put make it says me that : cd /home/pi/magi; /bin/sh share/genbuild.sh /home/pi/magi/build/build.h

I think there is a problem. Can you help me ?

Hi erkallys,

appears libgmp needed for build.

try sudo apt-get install libgmp-dev and after try a rebuild.

Regards

digibob00 is correct - I totally missed libgmp because I use it for high precision math in one of the programs I deal with on a regular basis... I should have built the binaries on a clean build server to make sure everything worked as expected. Sorry for leading you astray, Erkallys.

On a semi-related note, my changes have been pushed to the official GitHub repo, so you should be able to pull the official source to build your wallet now.

nice coin

Thanks and welcome in our Magical community.

What is POM ?

Good question; no one was questioning this before, though we're talking "CPU mining | PoS-II | PoM | Unique BLK reward | [MagiPay]". PoM has more meaning (since we're advising 1st PoM) than a single campaign as done before (which was an approach to protect coin distribution): https://bitcointalk.org/index.php?topic=802681.0; some details here: http://arxiv.org/pdf/1409.7948v1.pdf

PoM - proof of mining; by it's definition, the more mining efforts being placed, the more rewards one gets. This is typically right in mining any coins, while it's particularly emphasized in Magi (on individuals' participation), because of the design of PoW block reward. A simple description of the block reward is that it decreases with increasing network hashrate, and may hit zero when network hash is significantly high. A consequence of this is big miners get frustrated. If one is familiar with the block reward (https://bitcointalk.org/index.php?topic=735170.msg9991269#msg9991269), you will see block reward could be easily hitting zero. A point here, which was also being argued among people, is who will exit if mining nothing? This is where PoM campaign will be functioning. The campaign will encourage people to keep mining by rewarding despite the amount of block reward. To understand the purpose of the PoM campaign , we can see what happens if we're on the opposite situation - what if generic miners quit first?: 1) big miners keep mining, 2) because of miners quitting, network hash getting low, block reward increasing, and big miners get rewarded more! So now you see PoM campaign is trying to protect the network and to ensure FAIR coin distribution.

To the individuals, PoM means one will receive better rewarding by long term mining. Provided that we, the generic miners, form a solid league, won't give up mining in any situation. One will receive less mining share if big miners are present since they have more hash weight over the rest of miners. It should be noted, however, that coin distribution is pretty much protected by the significantly reduced block reward, as much less coins will be mined in this case. At the time of big miners' leaving, network hash decreasing, not only one gets higher mining share, but also the block reward is high. Then you know why Magi can achieve the FAIRness in coin distribution.

Some good news for the community:
We can start a new PoM soon.
Always good to recieve more donations   (99TPno3sPeUfDh9tq4To7xkLAYNQV1Qri1)
but for starting the new PoM we achieved more than minimum required fund. Thanks for that.
Team is working now on solid and fair plan.

is there a list of all the available pools somewhere?

is there a list of all the available pools somewhere?

http://poolinfo.coinmagi.org/ is probably where you want to check.

[Erkallys]

Is it better to mine on a pool with a higher or a lower hash rate ?

[z0n0]

what happened with block reward yst/today? from 5xmg earnings a day (few days ago) to 25 xmg ystday

[QuantumSheep]

i'm hitting around 4.7 a day.

the pool stats quote higher but other variables are at work and that calculation doesn't factor those in.

Maybe Magic?

Basically it's jumping; one may need to stick to mining so won't missing high reward blocks.

Btw, does the qt-wallet work now?

Thanks for update. Funds so far are about 23K XMG or so.

You havent enought RAM Create a big Swap File (1GB):

free
dd if=/dev/zero of=/var/swap.img bs=1024k count=1000
mkswap /var/swap.img
swapon /var/swap.img
free

and compile again...

dd if=/dev/zero of=/var/swap.img bs=1024k count=1000
dd: ouverture de (open of in English) « /var/swap.img »: Permission non accordée (Access denied in English)

It will never work ...

should be:

Code:

sudo dd if=/dev/zero of=/var/swap.img bs=1024k count=1000

add "sudo" for other commands too.

I hope. Linux is definitely tricky !

That's nice! Think there will be another donation coming! Will let you know tonight!

I won't be able participate to that campaign

Erkallys why not? Are you a miner? If you are you might join the PoM.

Yes I am but I couldn't let my computer mine for months.
