Hello,

here is a link to a compiled machinecoin-qt v0.14.2.0–3c52e42 (64-bit) for ubuntu 16.04.03 desktop-amd64. It was compiled by v1nc:

https://mega.nz/#F!kSxTVDyY!9Qih_peC_SXfLRGhtEW6Wg

I did the following to get it running. It was a bit of trial and error, so not everything may be necessary.

1  sudo apt-get install libboost-all-dev
2  sudo apt-get install libzmq3-dev
3  sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler
4  sudo apt-get install libqrencode-dev
5  sudo add-apt-repository ppa:bitcoin/bitcoin
6  sudo apt-get update
7  sudo apt-get install -y libdb4.8-dev libdb4.8++-dev   
8  sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils

Greetings, friends at Machinecoin! As Komodo Platform has been working around the clock to fine-tune the multiple GUI's that are the face of our Agama multiwallet and BarterDEX atomic swap protocols, there have obviously been many bugs found and many debugged. However, one bug in particular was found not only in our Agama GUI wallet, but also in the zcash4mac GUI swing wallet. It is a simple bug, but it warrants your attention. This is a potential money cost bug, and as a Bitcoin-protocol cryptocurrency, your GUI wallet(s) may be susceptible. We are reaching out directly to the developers and communities of the 60+ coins featured on Agama and BarterDEX as the bug may have a direct impact on you (via your own wallet).

watchonly-GUI bug: 'watchonly' addresses appearing as your own in GUI wallet; users could potentially send funds to the address, unaware it is not theirs or available for withdrawal. You can import and it becomes a 'watchonly' address. The GUI will display the address as yours, add its funds to your balance, and accept deposits, but cannot be withdrawn. This could be a normal address, my address, a p2sh address, satoshi's address, etc. This can be confusing to an end-user and will lead to many headaches for the developer, as is always the case with misplaced funds.

FOUND: in Komodo Platform's Agama multiwallet (fixed) and zcash4mac GUI swing wallet (@jl777B: "newest QT wallet seems ok about watch only, but not sure of older and when it was fixed")

ex. @grewalsatinder found the bug in his zcash swing wallet:

Quote from: jl777B
"satinder used zcash4mac, ie. the zcash osx GUI, not ours... the assumption is no GUI out there properly handles watch only addresses, until proven that they do... agama also had this bug, which we found and fixed, so it seems a very common bug to have"

SOLUTION: For the 'watchonly' address or any address not yours, the value 'ismine' returns false. Any such address gets filtered out.

QUESTIONS:
  • How does your recommended GUI deal with watchonly addresses?
  • Does your GUI display watchonly addresses as different than actual addresses in the wallet?

We need to experiment a bit to see which approach gets a better response triggering the bug. People WILL lose money if they send funds to a watchonly address.

Quote from: jl777B
"the t3 addresses in the 'Own Addresses' column! and they absolutely cant be as they are p2sh addresses. it is clear proof that the bug is very real and anybody that understands a p2sh address will understand it cant be something in your wallet. it is usually a multisig address, so only if it is a 1of1 multisig (possible but very silly) can you have a p2sh address that is spendable, but the wallet wont even know it... normal addresses can also be watchonly, which makes this even worse. in that case it would appear in the list of addresses just like all the others. even if you are able to spot p2sh addresses visually, it wont be enough"

We want to spread awareness and facilitate discussion of this bug to minimize the impact.

Of course - we can always talk about how you can use BarterDEX today to trade Machinecoin via atomic swap directly with your peers, through our beta GUI and without downloading the entire blockchain ; ) That is how we found the bug, afterall.

Stay safe,
Jay

Hey Jay,

thanks for letting us know about this.

I can confirm, that this "bug" is appearing at the latest Machinecoin Core 0.14.2 and may be confusing for most users and a risk for losing coins (see https://gyazo.com/25fdb2e3be7aa41ee900e4c6ecadf6ec).
I'll work on a solution to clarify the difference between "normal" and "watchonly" addresses within the GUI, which will get pushed with the next core version (most approx. 0.15.x).

Hi Jay, sorry for later answer, we are not here every day - anyway SkycityVictorians will investigate it and let you and all know soon.
btw first look at your message seems scary, but i don't think that its Machinecoin's case, 100% answer will be provided by Skycity

Hello,

sometime ago the user rossen compiled machinecoin version 0.13.1.1 for ubuntu 16.04. The results are still available at:
https://cointech.net/machinecoin-compiled-daemon-and-tools-for-ubuntu-16-04/

I appreciate the effort, but is there a chance to get a manual for compiling machinecoin for ubuntu or raspberry pi? I tried it by myself, but I always get stuck at some point. I followed the directions in:
https://github.com/machinecoin-project/machinecoin-core/blob/0.14.2/doc/build-unix.md
but no success.

I just used the Fedora notes on that page to install it on CentOS and it worked great... I will try to build it on Ubuntu later on this evening.

Fedora/RedHat/CentOS has stripped SSL library and it is not good to use/compile. So I will take a look if I can build a static binary files.
I am surprised about the new version now, but feel free to join my FB page and post news : https://www.facebook.com/cointech.net

Is there an ETA for MAC masternodes? Also, the final amount is 10K as I heard last time?
Thank you.

Hey yo,

so..currently there is no official ETA when masternodes are ready..however, they're in progress and they'll got finished within the next months (1-3 months).

I know "some months" sounds really long, but I got some more very important personal stuff to do first.

The masternodes amount we've decided is 25k MAC / node.

On which exchanges will tokens be traded?


Can be traded on Cryptopia, CoinExchange and Nova. But, practically only on Cryptopia, volume being very low.


And Nova is closing. CoinExchange actually has some for sale, but like a lot of their other coins, it lacks buy support over there.
