1  Bitcoin / Electrum / bitcoin is hackable on electrum-2.9.3-portable news may 2018 on: May 21, 2018, 03:18:55 PM
hello friends just to let the bitcoin community know that to my best knowledge I have figured out that
on 10th may 2018 I lost BTC0.00564505 bitcoin worth $50 at rate $8900 due to a hacking issue and unauthorized transaction
caused inside my electrium-2.9.3-portable version which was encrypted with 24 digits complex password.

here I want to mention that it is my 3rd created electrium account for safety reason where I used new unique
seed to create my wallet and put password on it. and that my pc is never shared with anyone, not given
for repairmen and I have up to date windows 8.1 platform with avast antivirus and up to date router
which is not easily be hacked. so hope it will be a good notification to record for inquiry.

the transaction id is : https://blockchain.info/tx/af59d8a4cf4a7f0582055b6edf0d0ffecd4072974fc8c2631e3cd3de8d3152a5

its to be noted that the hacker took all my balance at once causing my account to be turned out to be 0.
2  Alternate cryptocurrencies / Mining (Altcoins) / Solo Mining on Windows with s5 antminer not working or connecting on: January 04, 2018, 12:36:42 PM
Hi
I am newbie to cryptocurrency , and to my knowledge I know solo mining bitcoin with s5 antminer is
just a joke in 2018. But I guess its not beyond expectation for new sha256 coin that are similar to bitcoin.
so solo mining guide on own network with own pc with s5 anminer will come handy.
Here I shall try an example with eMark coin or DEM Coin.

First of all I have downloaded and synchronized eMark-qt.exe
then I have created a eMark.conf as per the suggestion found in help>console>command line option
I have created another eMark-qt.conf just for over sure and suggestion through out internet as .conf
should be similar to the name of the qt wallet here eMark-qt.xxx
my .conf file is as follows :
-----
rpcuser=eMarkuser
rpcpassword=12345
rpcallowip=*
rpcconnect=192.168.0.3
rpcport=16666
daemon=1
server=1
gen=1
listen=1
-----
rpcconnect=192.168.0.3 is my laptop ip where I am running the qt wallet as server
rpcallowip=* is any ip can connect to my laptop server such as another pc of my
localnetwork with a graphics card to mine and mainly our s5 antminer which
ip is here : 192.168.0.2

now I ran the qt wallet by creating a bat file called :servereMarkcoin.bat
with the data that inside the quote and put in the same folder
as eMark-qt.exe: "eMark-qt.exe -server"
then I doubled clicked the bat and the qt wallet popped in and ran as server
we can also do this by creating a shortcut of eMark-qt.exe somewhere and
from the shortcut poperties adding the "-server" and then clicking the shortcut
to run qt wallet as server.

now in the router I made a port forwarding by adding web service with ip : 192.168.0.3 with
the port 16666 which I selected for the eMark-qt.exe in the .conf file

now when everything is running : I opened cg miner 3.7.1 and tried to mine with my
usb block erupter it found the url and active pool an dstarted hashing
my pool is here http://192.168.0.3:16666 user -eMarkuser pass -12345
I also did it with cpuminer to mine with cpu with following info in .bat file
minerd -a cryptonight -o stratum+tcp://192.168.0.3:16666 -O eMarkuser:12345
****here http://192.168.0.3:16666 didnt work but stratum+tcp://192.168.0.3:16666 worked fine instead

NOW THE PROBLEM IS ######

I tried to login to my s5 antminer by accessing to http://192.168.0.2
and in the miner configuration neither  http://192.168.0.3:16666 works nor
stratum+tcp://192.168.0.3:16666 so how can I solo mine or connect to my laptop
is it because only asic miner that are connected to my laptop can solo mine
and as antminer is another device and my laptop is not a public pool but solo mining server
so my s5 antminer can not participate and mine?
