Yesterday was the official release of the new flagship product — Tkey Messenger. Messenger is available in the browser and on desktops for the most popular systems Windows, macOS, and Linux. Soon, smartphone owners will be able to try out Tkey Messenger in action, the app will appear in the App Store and Google Play.
https://preview.redd.it/f4ca4g0nue651.png?width=1400&format=png&auto=webp&s=c857c896bf71771e3d01e0210f24da9a4fb68887
In the era of rapid communication and technology development, messengers have become our default products. We use them for business purposes, to communicate with friends and acquaintances — this has long been the norm. It would seem that why are other messengers created when there are many other instant messaging systems?
Today we will talk about what a Tkey Messenger is, what it can do today, what features will be included in it in the future, and most importantly, what we are creating It for and how we will develop it.

TKEY.ME

The abbreviated name of Tkey Messenger is tkey.me. First of all, TKEY-ME is a secure messenger with p2p audio and video calls, and in the future, a built-in digital wallet.
“Every day we communicate in messengers. We earn money at work. We make purchases and transfers. We are here to combine these processes in one application and make sending funds as easy as sending a message”

The Tkey Messenger as a new ecosystem

Do you think we are here to compete with other messengers? — No, there are a lot of great messengers. We are here to create our ecosystem and the internal market in it. Combine these processes in one application and make sending funds as easy as sending a message.
After all, we work in the field of FINTECH, cryptography, and blockchain, why not apply the best practices and knowledge in practice? Therefore, the TKEY Messenger should be considered for a large ecosystem.
This is a new payment segment that covers fast communication tools in combination with an internal payment system, a set of exchange practices, blockchain, cryptography, our own experience, and the experience of global companies.

How will the Tkey Messenger ecosystem work?

https://preview.redd.it/17bml1zpue651.png?width=1400&format=png&auto=webp&s=99ebd70745968452536546fb5a59841e8f3a9c52
Let’s start with the most important thing: money should be sent in a matter of seconds, regardless of the country of issue of the Bankcard and wherever you are.

Here is a simple example:

You or your relatives live abroad and you want to send funds quickly, for example, 2600 USD — you just open a chat with your loved one, send a message and 2600 USD in the same second become available on your loved one’s account.
https://preview.redd.it/nmz4ienrue651.png?width=697&format=png&auto=webp&s=c3902fc0df1ed2eba425c3f3db3eb8c40bc7a237
It turns out that you can exchange Tkeycoin for USD, EUR, or GBP in a matter of seconds, as well as instantly send them to any place in the world and without hidden fees, the exchange amount is immediately available on the screen.
Or you have Bitcoin, and the Recipient needs dollars — Tkey Messenger will take care of all the complex tasks, you will only need to send a message to make the payment.
Each completed payment will be processed through a digital payment system without Bank intervention. You can link your Bank card to automatically withdraw digital funds to your local currency.

Do you want to simplify payments even more?

Order a TKEY card, and it will automatically be linked to your Tkey Messenger account. Make payments online, make purchases in stores — it’s just as easy as you did before, only much more convenient, faster, and safer.
https://preview.redd.it/42f1dkktue651.png?width=1400&format=png&auto=webp&s=7305192230c379c0fe81d981208a8cef8a540a5c
The most important thing is that you can easily use digital assets in combination with Fiat currencies — just top up your account in messenger to start sending currency around the world.
“Moving money around the world should be as easy and cheap as sending a message. It doesn’t matter where you live, what you do, or how much you earn.”

Send TKEY or Bitcoin via message, has it become a reality?

In Tkey Messenger, you will be able to quickly send digital currency using a message. You can not specify a public address, but send a digital currency using a message.
Instantly send funds to friends or relatives anywhere in the world. No Bank, no problems, no hidden fees.

Top up your mobile phone or pay for the Internet?

The usual payments, such as the Internet or mobile payments, will certainly be available, because if we can transfer pounds from England to Canada in a matter of seconds, and the recipient will receive dollars, why can’t we make a payment for the Internet? “Of course you can.

Transfer funds by a nickname

You don’t need to know the recipient’s account, just send funds by their nickname to the Tkey Messenger, and the funds will arrive within a few seconds. Fast, convenient, and safe.

What do we get in the future when using a Tkey Messenger?

We get an ideal payment system with instant transactions, fast access to various currencies, including digital, instant international payments, a huge platform for business, a marketplace with trusted sellers, secure transactions, while fast communication, p2p calls, and video communication. Not to mention various chips, in the format: cashback, savings account, invest. products, etc.
  • International transfers without Commission and in seconds;
  • Instant account opening — just create an account to get access to payments;
  • Access to funds 24/7/365 wherever you are.
  • Multi-currency wallet — you can use both digital currencies and classic currencies, such as the pound, euro, and dollar.
  • Payment in digital currency anywhere in the world.
  • Save time and money.

How is this possible, you say?

More than real, we will answer. At the very beginning of the project, we planned to create a marketplace, and then finalized the concept with NFC payments in TkeyPay. Smoothly, all this develops into a single system, which will be merged into a Tkey Messenger.
The Tkey Messenger is convenient and secure, payment system, and marketplace. The entire financial industry is in your hands-in your smartphone.
https://preview.redd.it/ullvuelexe651.png?width=1001&format=png&auto=webp&s=ef883fa9de067b885138a231069ddc3c0414c7d3
The mobile Finance industry is developing rapidly against the backdrop of a growing number of Internet users and the increasing role of smartphones in modern life. Today, the mobile device market attracts about 2 billion people, who remain passive players in financial markets.
With the Tkey Messenger access, you always get access to instant Finance, shopping, and the nice things you want to get here and now. In practice, it has turned out that we can often forget the keys to the apartment, rather than the phone, so your finances will always be with you.

Join the global Tkey Messenger system right now

Release 1.0.0 is available in the web version and for Windows, macOS, and Linux operating systems, and shortly on your mobile devices.

Current functionality of Tkey Messenger 1.0.0

The Tkey Messenger version 1.0.0 is the core that opens up new features that we discussed above, payments, and more. Now it is a convenient and stylish messenger with an intuitive design, instant messaging, and secure audio and video communication.

The P2P audio and video calls in a Tkey Messenger

When creating the first version, we focused on high-quality video and audio communication. Now you can easily call by video and be sure that you will get a high-quality video stream, as well as the absence of restrictions from third parties because the connection is carried out on the principle of p2p.
Audio and video calls are made in p2p mode, so there is no recording of calls at all.
https://preview.redd.it/lyrnkfhgxe651.png?width=1384&format=png&auto=webp&s=fb0c93ca45fa6bd4f65c77f64c81b88b906e904a
You can chat with friends and colleagues around the world for free, and excellent audio and video quality will only positively affect the quality of your conversation.

Calls in the web version

The web version of Tkey Messenger is available at → http://web.tkey.me/. The web version has full call functionality, so you can easily call through it, both via video and audio.
Video calls are available with the “Share” function, you can easily “share” your screen for the interlocutor and show what is happening on it. This function can be used for presentations or training events.
Screen Sharing is a demonstration and broadcast of the screen. “Share” your screen for the interlocutor and show what is happening on it.
https://preview.redd.it/x5h6au9ixe651.png?width=459&format=png&auto=webp&s=9b71b9148b17b55636c5615cbf7d6535cc78aa56

Group video and audio calls for up to 50 people

In the web version, you can launch a group video call. In the chat, tap the “handset” icon — the call will be sent to all participants in the chat, so all participants in the group chat can hold a video conference of up to 50 people. The user can turn on the camera and not turn it on, but simply participate in a video conference via audio.
On average, messengers that support the function of video calls in high quality, hold a video stream of no more than 8–10 people. In a Tkey Messenger, group conferences support up to 50 people. Soon-public online broadcasts and streams.
On the call page, you can conveniently distribute the Windows of the connected video stream.
https://preview.redd.it/qf85k37kxe651.png?width=744&format=png&auto=webp&s=8074a48fca7ea492376460d5c15f1de27722f7ea

Unlimited private group chats

The first version only supports private chats and group chats. Group chats are also completely private, so there is no “Share” function, only the chat participant can invite another participant to the group chat.
Create your thematic chats. Work. Family. Friends. Be the first while we develop. Soon-public channels and chats.
Anyone can start an audio or video call, and the notification goes through all participants. Switching to audio or video mode can be switched right at the moment of the call.
As we have already mentioned, group chats are completely private. You can make video and audio calls, send messages, and invite other participants.
To invite a new chat participant, any user can invite another user to a group chat. To do this, click on the “three points” menu icon.

https://preview.redd.it/cyfuh6snxe651.png?width=428&format=png&auto=webp&s=ee38ed7f20fed0bcb576279a6701397cd777e913
Next, enter the nickname of the participant you want to invite to the group chat in the search.

https://preview.redd.it/v7pltoppxe651.png?width=367&format=png&auto=webp&s=71d71bb795b312b4607d2033eee4c3a29f3b7500

Deleting information in group chats

Each participant, when they click the “Exit and delete” button, deletes messages and information from the chat on their side.
In group chats, all information is deleted by the last person to leave the group chat. After deleting-all messages, media, photos, and other data that were in this chat are automatically deleted. If all participants leave the group chat, it will be automatically deleted, and all information published in the group chat will also be deleted.

The chat between the two parties

This is a classic private chat between two participants, instant messaging, sending media.
The rights of the participants are equal. Any chat participant can delete the entire chat. after deleting all messages, media, photos, and other data that was in this chat, it is automatically deleted.

How to make a mobile wallet connect to my full node through Electrum Personal Server?

I have Bitcoin Core (full sync) and Electum personal server with basic configuration in linux (mint) but I don't have enough technical knowledge on how to connect to mobille wallets like bluewallet, samourai, breadwallet (BRD), coinomi etc, all of them unfortunately require that connect to an electrum server instead of our own node (direct enter IP address).
But unfortunately I can't find any tutorial on the internet, could someone please tell me what to do?
Detail: Some wallets like Bitcoin wallet for android (schildbacth wallet) and BRD allow you to connect to your full node just by adding your IP address (which would be much easier and more convenient), however my node is configured with tor and these apps do not add address .onion.
Is it possible to do this only using the electrum personal server or EPS only connects locally and does not allow more than one connection?
Do I have to install another electrum server like ElectrumX?
Do I need to create an alias certificate to connect to these mobile wallets?
Motivation: Why the need to connect these mobille wallet apps to my own node since these apps automatically connect to their own servers, and obviously will require a lot of technical knowledge in addition to time?? Because I care a lot about my privacy and I believe that most users that run full node not only to help the network, but to validate and transmit their own transactions instead of relying on third parties for this function. One of my motivations is also because I have a full node and I want to live up to the almost 300gb that occupy my HDD, I have already managed to make my Electrum wallet to connect to my full node through EPS, now my goal is to connect mobille wallets with my own node that have this option. 
Thankful.

Good idea to add Monero GUI to Ubuntu Software?

Making various Monero wallets easier to install and use is a good goal and worthy of our efforts. To make the Monero GUI wallet easier to install on Ubuntu Linux do you think it would be a good idea to have the installer added to the Ubuntu Software center? Would this open the Monero GUI software to a potential security attack? I remember Linux Mint got hacked where the binaries for the ISO were altered to include malware. On a side note the Bitcoin Core software is available in the Ubuntu Software center.

PIVX Core v3.0.6 released (November 30th) - Optional Upgrade

Github release info and binaries
Forum Post
Important information about the automint and zPIV backup requirements

How to Upgrade

This release is optional but recommended. The latest mandatory upgrade is v3.0.5.1, but if you have any problems with earlier versions the latest version is recommended.
If you are running an older version, gracefully shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/PIVX-Qt (on Mac) or pivxd/pivx-qt (on Linux).
There are no special steps needed like config file changes but a backup is always a good idea.
A note from presstab in case it gets buried in the comments
Command line install and upgrade guide

Notable Changes

(but you should still read the release notes on Github)

Automated Database Corruption Repair

There have been cases of blockchain database corruption that can occur when PIVX client is not closed gracefully. The most common cases of corruption have been identified and the wallet will now automatically fix most of these corruptions. Certain corruption states are still unable to be fixed, but now provide more detailed error messages to the user as well as prompting the user to reindex their database.

More Accurate Error Messages

Some error messages in the wallet have been too vague and done little to help developers and the support team properly identify issues. Error messages have been refined and are now more specific.

Reduction of Debug Log Spam

Many 3rd party services have reported that their debug logs have been overloaded with messages about unknown transaction types. This log spam has been fixed.

Removal of Heavy Running Transaction Search Code

Many areas of the block validation code use a "slow" transaction search, which searches redundantly for transactions. This "slow" search has been removed upstream in Bitcoin and is now removed in PIVX. This provides a more efficient syncing process and generally better performing wallet.

Sync Fix for Block 908000

Many wallets were having trouble getting past block 908000. This block recalculates certain aspects of the money supply and zPIV transactions, and is known to take longer to sync. Code has been added to allow block 908000 to be validated without the user needing to enter any special commands into the debug console.

Working Testnet

Testnet is now accessible with this release of the wallet. Testnet can be accessed using the -testnet startup flag.

zPIV Spending Fix

zPIV that were minted between block 891730 and 895400 were experiencing an error initializing the accumulator witness data correctly, causing an inability to spend those mints. This has been fixed.

PIVX Core Wallet 3.0.5 final release (November 13th, 2017) - Mandatory Upgrade

Github release link
Forum Post

Important Notes

Upgrade instructions

1- Download the appropriate release for your platform from the Github release link. For command line installs/updates this link may help.
2- Start up your client and see if you are on the wrong chain by using this link (Am I forked?) or manually comparing your latest block hash against the [block explorer](www.presstab.pw/phpexplorePIVX/index.php#)
3- If you are on the correct chain, let it fully sync (or as far as it will go) and then repeat step 2. If you are still on the right chain move on to step 4. If you're on the wrong chain, download the chainstate from this link (mirror) and follow the instructions to install it. Do NOT delete wallet.dat or your backups folder. Once this is done, restart your client and let it finish syncing
  1. stop your wallet and/or daemon
  2. locate the folder with the blockchain folders (usually ~/.pivx/)
  3. do a complete(!) backup of this folder in case something goes wrong
  4. completely remove the folders "blocks", "chainstate", "sporks" and "zerocoin"
  5. download one of the snapshot-files (preferably the newest one) above into this folder
  6. unpack the snapshot file: 'unzip '
  7. the folders deleted above are now replaced by the ones from the snapshot
  8. restart your wallet and/or daemon
4- On this step you should be fully synced and on the right chain. Using the debug screen or pivx-cli, use the command
spork show 
to output your spork status. Have a look at spork 16 and make sure the value is 1510179528 (now 1609459199). If it is, go ahead and start staking.
If you are having trouble getting the correct value for spork 16, try adding nodes to your pivx.conf file that are protocol 70912. A list of 70912 nodes can be found at http://www.presstab.pw/phpexplorePIVX/nodes.php . This can be done from the debug menu or with pivx-cli by saying
addnode 123.45.67.89 add 

Notable Changes

libzerocoin Exploit Fix

zPIV relies on a 3rd party library called libzerocoin. All currencies that utilize the zerocoin protocol use libzerocoin, and many of those currencies have been exposed to an exploit which allowed for the creation of multiple zero-knowledge spending proofs for one single zerocoin mint. The PIVX developers were able properly identify the exploit, track down any fraudulent spending proofs, link the fraudulent spending proofs with their one valid proof that they were mutated from, and remove any mints from the accumulators that were derived from the invalid spends.

zPIV Maintenance Mode Spork

Handling the above noted libzerocoin exploit required the PIVX team to immediately release a patched wallet to as many users as possible which rejected bad spends and also disabled all zPIV transactions in general. The process of releasing a patched wallet in such a small time frame is frustrating and difficult for all members of the PIVX team and especially users of PIVX. The PIVX developers have added a new spork which allows for zPIV transacting to be turned on/off without having to release a patched wallet. This will allow much smoother operation if any problems occur in the future, and should also allow exchanges and 3rd party services to continue to operate even if zPIV is in maintenance mode.

Accumulator Code Refactor

The zPIV accumulator code has undergone a major refactor. Accumulators are one of the most essential components of the zerocoin protocol, and also one of the most computationally expensive parts of the protocol. This refactoring speeds up syncing and spending of zPIV by over 5x. The new code also allows for spending of zPIV with only 2 required mints occurring on the network after your mint has been added, whereas before 3 were required. This refactor allows for lighter resource load and a smoother user experience.

Money Supply Indexing

The exploit in libzerocoin threw off some of the wallet's internal money supply calculations for both the zPIV supply and the PIV supply. User's wallet's will automatically recalculate the supply on block 908001. User's also have the ability to recalculate supply using the startup flag reindexmoneysupply.

More Extensive Tracking of zPIV Supply Through RPC

More information has been added to the getinfo and getblock RPC calls, which now display the total zPIV supply as well as the balance for each zPIV accumulator.

Multisig GUI

Provides functionality which is currently only available through raw transactions. Multisignature addresses require signatures from multiple parties before coins belonging to the address are spent. Accessed through the File dropdown menu.

FAQ

  • Will I lose piv or zpiv?
    • No. Backup your wallet.dat again for good measure and never delete a wallet.dat file.
  • My wallet is stuck on block ?
    • Check if you're forked (Am I forked?) and then check if you're really on v3.0.5. If you're on the right version and chain, just hang tight and your wallet will find a good node to sync with eventually. Contact support if it's more than a few hours and the problem persists
  • My zPIV balance is incorrect
    • Contact support in discord or via the Support Portal. Please note that during the upgrade period and zerocoin maintenance mode there may be delays.

I’m impressed with Peach Wallet: desktop+mobile lightning wallet. Trivial installation from AppImage, great UX.

Wow! I am impressed with how smooth this app is.
Your own Lightning node made simple! Everybody should be able to install this one.
Installation is trivial if you “install” it from AppImage (one executable file that runs everything, therefore it is barely “installation”, more like download one big file and run it).
download: https://lightningpeach.com/peach-wallet
You can’t see source code this way, you have to trust BitFury. If you are exchange or custody or something big - go with Github source code installation (app is open source).
Connecting mobile app to your wallet is simple QR code scan. It actually works. You should open ports 9735 and 10014 on your VPN or router. It works great with pinned IP address over VPN. I don’t know how good it works on regular IP address.
Some privacy concerns regarding data collection:
  1. you should disable Google Analytics in Settings
  2. you should opt for Standard Mode during install (Extended Mode has privacy concerns?)
https://bitcoinmagazine.com/articles/can-i-trust-bitfurys-peach-lightning-with-my-data-maybe/
I am in no way associated with BirFury or development of this app.
edit:
I have run different lightning implementations since middle of last year. I started with Windows (Bitcoin Core, Enclair and LND on same bitcoind). Now I run Linux (Bitcoin Core, LND + RTL wallet, C-lightning + Spark wallet, both on same bitcoind). Linux installations are very tricky to do for non-technical person, so if you are considering Linux you should reconsider. Othervise, Linux Mint is fucking amazing. Windows is somewhat easier, but is way less reliable os. I haven't tried Mac Os installations.
This Peach Lightning Wallet installation is targeted for average desktop user. If you know how to use your fucking Windows Explorer and how to configure your bloody router, you are good. Mobile app looks and works great. It even has NFC! Yeey

Just had a virus try to steal (ended up hidden) my bitcoins in Electrum...under Linux...

Been running linux mint and there is a lot of strange activity watching the firewall (got it on near lockldown). I had to boot into another linux so that i could scan around and eventually by luck, i found my wallet.dat file but it was somewhere far into the root of the drive, locked. 'Files haven been locking, and it has been obvious someone has been able to control my computer remotely. I thought this only happened with windows?
I recovered the money and am now investigating what it could have been, a bug in ubuntu/mint leaving VNC on all day?
I was going to Install Debian last night and the thing hanged probably couldn't handle some generic drivers....
I want something secure and stable and a firewall that works (i could see the person executing a command in /usr to enable variuous firewall options, as i closed them)
Any idea's? I can post up some of the code in the replies some of it loos sophisticated and its writtenin python. Lots of python code, and lots of bitcoin searching.

Dogecoin on Linux - The Complete Beginner's Guide

I'm writing this because I couldn't find a single condensed guide on compiling the wallet and running mining software on linux, specficially Ubuntu/Linux Mint. I combed Bitcoin and Litecoin forums for similar problems I was running into and eventually got everything nailed down, so here it is in one place, for new Shibes.
If you want to make a Dogecoin directory in your downloads folder to keep things organized, you will need to modify these commands to refelct the change. So instead of going to ~/Downloads/ you will need to go to ~/Downloads/Dogecoin and be sure to put the zipped files there when you download them, but the commands will be the same otherwise.
cwayne18 put in the work to make a PPA for the QT client here.
Ubunutu/Mint/Debian users should be able to install the client with the following commands:
sudo add-apt-repository ppa:cwayne18/doge sudo apt-get update && sudo apt-get install dogecoin-qt 
To update using this method, run
sudo apt-get update && sudo apt-get upgrade dogecoin-qt 
Compiling the Wallet Manually
I suggest using the PPA above, but if you want to compile manually, here you go.
1)Download the newest source from here. If you want to check out the Github page, click here
2)Unzip the package with the native client OR, navigate to your downloads and unzip
cd ~/Downloads unzip dogecoin-master.zip 
3)Now it's time to compile. You will need to install the dependencies, just copy and paste the following code. It will be a fairly large download and could take some time. It is always important to update before installing any new software, so we'll do that first and then install the dependencies.
sudo apt-get update sudo apt-get upgrade sudo apt-get install libssl-dev libdb-dev libdb++-dev libqrencode-dev qt4-qmake libqtgui4 libqt4-dev sudo apt-get install libminiupnpc-dev libminiupnpc8 libboost-all-dev build-essential git libboost1.53-all-dev 
4)Once that is done, go to the doge-coin master directory and compile:
cd ~/Downloads/dogecoin-maste sed -i 's/-mgw46-mt-sd-1_53//g' dogecoin-qt.pro qmake USE_UPNP=- USE_QRCODE=0 USE_IPV6=0 make -j3 
After running the qmake command you will likely see some text similar to
Project MESSAGE: Building without UPNP support Project MESSAGE: Building with UPNP supportRemoved plural forms as the target language has less forms. If this sounds wrong, possibly the target language is not set or recognized. 
It's perfectly normal, so don't worry about that.
Your Dogewallet is ready to go! The executable is in ~/Downloads/dogecoin-maste and called dogecoin-qt. Your wallet information is in ~/.dogecoin. You can run the wallet at any time by opening terminal and typing
cd ~/Downloads/dogecoin-maste ./dogecoin-qt 
Future upgrades to dogewallet are easy. Back up your wallet.dat, and simply follow the same directions above, but you'll be unzipping and building the newer version. You will likely need to rename the old dogecoin-master directory in ~/Downloads before unzipping the newest version and building. Also, it is likely that you will not need to install the dependencies again.
Alternate Method For Installing Dogecoin Wallet from Nicebreakfast
After installing the dependencies listed in step 3, open terminal, then navigate to where you want Dogecoin Wallet stored and run:
git clone https://github.com/dogecoin/dogecoin ./autogen.sh ./configure make 
then when the wallet is updated just run
git pull 
from the dogecoin directory.
GPU Mining
GPU mining requires CGminer. My suggestion is to get the executable already built. The creator of cgminer has removed the built file from his website, but I've uploaded it here
sudo apt-get install pkg-config opencl-dev libcurl4-openssl-dev autoconf libtool automake m4 ncurses-dev cd ~/Downloads tar -xvf cgminer-3.7.2-x86_64-built.tar.bz2 
Don't use anything newer than 3.7.2. The newer versions of CGMiner don't support GPU mining.
That's it! You have cgminer ready to go! You will run cgminer with the following syntax
cd ~/Downloads/cgminer-3.7.2-x86_64-built/ ./cgminer --scrypt -o stratum+tcp://SERVERNAME:PORT -u WORKER.ID -p PASS 
A good guide for fine tuning cgminer can be found here; follow the litecoin example.
EDIT
I had trouble getting cgminer running with a single line command, but running it via an executable .sh file works. This is covered in the cgminer setup guide I posted above but I'll put it here too. In the same directory that has the cgminer executable, you need to make a file called cgminer.sh and make it executable. It should contain the follwing:
export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export DISPLAY=:0 find *.bin -delete sleep 5 ./cgminer 
Then you can call cgminer in terminal by doing ./cgminer.sh You will need a cgminer.conf file containing all your options. All of this is covered in the guide that is linked above.
A quick note about AMD drivers: They used to be a huge PITA to install and get working, but the newest Catalyst drivers are great. There's a GUI installer, everything works out of the box, and there is a lot of documentation. You can download them here: AMD Catalyst 14.6 Beta Linux
CPU Mining
For CPU mining I use minerd because it doesn't require any work to get running, simply download it and get to work. Download the built file for your machine 32-bit or 64-bit, and then unzip it and you're ready to go!
cd ~/Downloads tar -xvf pooler-cpuminer-2.3.2-linux-x86.tar.gz 
The executable is called minerd and it will be in ~/Downloads but you can move it to wherever you like. To run it, pull up terminal and do
cd ~/Downloads minerd --url=stratum+tcp://SERVER:PORT --userpass=USERNAME.WORKERNAME:WORKERPASSWORD 
You're done! Happy mining!
Common Issues
I ran into this and I've seen others with this problem as well. Everything installs fine but there is a shared library file that isn't where it should be. In fact, it isn't there at all.
 libudev.so.1: cannot open shared object file: No such file or directory 
In terminal, do
sudo updatedb locate libudev.so.0.13.0 
And it will probably return a path /lib/x86_64-linux-gnu. Inside that directory there's a library file called libudev.so.0.13.0. You'll need to make a symlink (aka shortcut) that links libudev.so.1 to libudev.so.0.13.0 So, assuming you're working with libudev.so.0.13.0 do this
cd /lib/x86_64-linux-gnu sudo ln -s libudev.so.0.13.0 libudev.so.1 
Now if you do
ln -l 
You should see
libudev.so.1 -> ./libudev.so.0.13.0 
Meaning you've made the symlink. Also, the text for libudev.so.1 will be blue.

[Social X] Architecture of A Decentralised System for Social Payment and Services

Dear fellow Reddheads:
It's been a month since the successful launch of PoSV, which marked the end of stage one of Reddcoin project. There were three main goals for stage one:
  1. fair distribution of Reddcoin to common users (tipping), miners (mining) and investors (IPCO).
  2. an innovative algorithm to secure the network and encourage ownership, participation and decentralisation (PoSV).
  3. to build out a team of super talented and trustworthy developers.
The three goals have all been achieved so it's time for us to enter stage two: the buildout of services to make Reddcoin actually useful. This is what Social X is meant for. I'm still polishing the whitepaper to make it live up to my own self-imposed high standard, but I think the time is right for me to unveil it in broad strokes. There are three main problems Social X aims to solve.

Social X: why are wallets so difficult to use?

To achieve wide adoption of Reddcoin (or any cryptocurrency) by the non-tech-savvy general public, wallets must solve the following issues:
Ever increasing blockchain size discourages users from running full-blown wallets. It takes too much time and efforts to install or repair. A common user tends to find the process frustrating or even impenetrable and is forced to either give up adoption or rely on 3rd-party service providers (e.g. exchanges, wallets using ReddAPI) to take full control of her fund. Blockchain size grows everyday and grows faster with wider adoption.
Current wallets generate private keys randomly. As a user engages in staking or normal transactions, she has to back up wallet.dat file periodically to make sure all newly generated private keys are backed up. If wallet.dat file is corrupted or lost, there is no way to recover lost fund.
Again, due to the fact that private keys are randomly generated, it's impossible for a user to share the same wallet.dat file across multiple devices (e.g. desktop, iOS, Android) and multiple platforms (e.g. Windows, Linux, Mac). Different copies of wallet.dat will get out-of-sync. A user has to manage each wallet independently, which leads to significant operational burden and risk.
It would be extremely valuable for a service provider, such as an exchange or e-commerce site, to be able to generate unique public keys to receive fund while putting the corresponding private keys in cold storage. The impact on security is significant.

Social X: why is it so hard for me to tip someone?

One essential feature of Bitcoin is pseudo-anonymity. To pay someone, you need to get hold of her impenetrable public hash key, somehow. And the hash key, i.e. the wallet address, may not be valid a moment later because the owner might have lost the corresponding private key. Ironically, this awkwardness, even backwardness, is not perceived as a disadvantage by almost all the cryptocurrencies. In fact, on the contrary, the single biggest, hottest, most wanted feature is full decentralised anonymity, which has seen the rise and fall of many cryptocurrencies and their copycats. While all the other cryptocurrencies compete with each other on this front, Reddcoin, aiming to the social currency of the digital age, moves in the opposite direction. Social lives are not possible without social identities.

Social X: why can't I use a service without giving up control?

The vast majority of 3rd-party service providers which hold fund on a user's behalf has exclusive full control of her private keys. If a service is indeed worthy, a user has no choice but to trust the 3rd party with security and integrity. It's ironic, to say the least, that cryptocurrencies which are created to remove exactly this need for blind trust in middlemen end up in a much worse position than fiat currencies due to the fact that many cryptocurrency companies are unregulated and incompetent. Then the question is: is there a way to create an ecosystem where anyone can write and provide valuable social applications in a fully decentralised fashion?

Social X: Architecture for a Decentralised System for Social Payment and Services

Social X has many components which are already being actively developed. Below I give a brief description of some of them.
  1. In the future, there will be two types of official Reddcoin wallets. QT wallet and reddcoind are full wallets required to run a full node. A second type of wallets, called thin wallets or SPV wallets will use the technology of Electrum modified and enhanced to support PoSV and staking. These wallets include mobile wallets on iOS, Android, next-generation Social Wallet on desktop and wallets inside browsers (Chrome/Firefox/Safari). I've already finished writing and started testing the reference implementation of Reddcoin Electrum server and client. Each client only needs to download 25M of data vs the current full blockchain at 660M. This is how we solve the blockchain size problem.
  2. All our official wallets, whether full or thin, will be deterministic. All private keys are generated deterministically from a long passphrase. This passphrase is all you need to remember and backup and with it you can fully recover your wallet and funds anytime anywhere. You will also be able to support multiple wallets on multiple platforms and devices and they will all be in sync. This is how we solve the portability problem.
  3. All our official wallets, whether full or thin, will be hierarchical. They will allow users to generate public keys on demand while keeping private keys in cold storage. This is how we solve the cold storage problem.
  4. I'm writing code (~30% finished) for sth we call Reddcoin Social ID (Redd-ID):
    • It's a new service provided at the blockchain level.
    • It allow users to associate a username with one private key.
    • The user can choose to bundle extra information such as email, address and avatar.
    • The information is public and embedded in the blockchain. As a result, any user can send Reddcoin to another by simply specifying the recipient's Redd-ID.
    • Redd-ID registration costs Reddcoins. The costs vary depending on many factors such as the length of the username. For example, we expect popular names like tom to cost at least 7 figure.
    • Redd-ID registration is verified in PoSV blocks. Therefore all active Reddcoin stakers will be the provider of Redd-ID service.
    • Redd-ID registration fee goes to the Reddhead who successfully mints the PoSV block that verifies and confirms the registration. In a sense, it will feel like a lottery. And this is why this service doesn't make sense for any PoW coin where each block is pool-mined.
    • Redd-IDs can be transferred to new addresses and by default auto-expire annually and can be renewed.
    • Small Reddcoin holders, as long as they keep staking, may double, triple or 10x their existing holdings just by receiving registration fees.
    • Businesses and organisations can register usernames for purposes like receiving donation.
  5. There will be several services available to provide more ways for Redd-ID to be used on Internet. I don't want to disclose all our cards here. Please wait for my whitepaper and see what we have for you as surprises. Meanwhile, do share with us how you imagine Redd-ID can be used.
  6. Different components of Social X will allow decentralised tipping across all social networks. In our next-generation social tipping platform, there will be no tipbots! When you tip someone on Reddit, Twitter, Twitch, Youtube or Facebook, the tipping goes straight from local wallet, whether on your mobile or desktop to the recipient.
  7. There will be APIs to allow 3rd parties to write and offer decentralised social applications.

Social X: where are we now?

  1. I'm finishing the whitepaper in coming weeks (while writing a lot of code). The whitepaper will contains much more information than this post.
  2. Reddcoin Electrum wallets for iOS and Android are being actively developed.
  3. Reddcoin full wallets (QT/reddcoind) are already hierarchical deterministic in the development branch and are being internally tested.
  4. The Social Tipping Platform is being actively developed.
  5. I need volunteers to host and test Reddcoin Electrum server and clients. I'll make a separate post next week.

Epilogue

Below I'll only answer questions selectively. Much more details will be available in the whitepaper and there is no reason to jump the gun and repeat it here. Stage one took us 6 months. We expect stage two to take 6 months also. It may be the most exciting period in the history of Reddcoin project.

Step Inside... We are giving away 200,000,000 Karmacoin to **EVERYONE** Get+Karma, then Give+Karma to someone else!

The Giveaway is Complete. Head on over to our new home at Karmashares to see what we're up to now!

(We're giving away 200,000,000 Karmacoin over the next few days to everyone. See the "How Do I Get Karmacoin?" section below.)
WELCOME TO KARMACOIN
What is Karmacoin?
Karmacoin is a new way to show your family, friends, and others that you appreciate them. Think of it as a "Like" button that you can take anywhere. It's a P2P currency, like Bitcoin. You can use it to share with those you care about. We call it Give+Karma, because when you do good, good comes back to you.
You can think of Karmacoin as another way to say thanks. When you Give+Karma you're sharing your experience in a community where the little things matter. Random acts of kindness, caring about what others have to say, showing appreciation, being happy, doing good things, and enjoying life. It's the little things that count. And that's why we developed Karmacoin.
We're currently expanding our cause not just around the internet but around the world. We shared a summary of our business plan and project schedule with our community so that everyone knows what we're up to. Our goal is to become the #1 way for people to reward others, and be rewarded themselves. Karmacoin can be thought of as an incentive for more people to:
Our vision is a world where hundreds of millions of people around the world use Karmacoin everyday.
How Do I Get Karmacoin?
You can get Karmacoin from others who share it, or purchasing it from a trusted exchange like MintPal using your Bitcoin. In a few days we'll be announcing an easy way to buy Karmacoin using Paypal.
Luckily, to celebrate our new main website and a new place where you can share stories about people doing good things called Karmashare, both launching on March 20, we are giving away 200,000,000 Karmacoin so you can try it out!
**Be sure to subscribe to this subreddit ** And be sure to vote on the cointips tipbot when it replies
Be sure to download the Wallet for Windows, Mac, or Linux. (We're updating the graphics so don't be alarmed! It's the correct version.) Once you've installed this, you can click on the Receive tab, highlight the first row, and click the Copy button at the bottom. This is your new Karmacoin address ("Karmaddress") you can use to receive Karmacoin. (You can also send by clicking on the Send tab and entering the recipient's Karmaddress.) We're working on an easy-to-understand video tutorial now, and will be posting that for the community.
If someone is sending you Karma you can give them your new Karmaddress and you should receive it anywhere from 15 seconds to a few minutes.
Our website will soon offer some instructions of how to get and use Karmacoin. Stay tuned...
The Karmacoin Vision
We believe that the micro-transaction economy is based on kindness, sharing, small donations, microloans, tipping, and the little things that can make life wonderful and people feel appreciated, including:
  • Online tips to other internet users who deserve a little recognition
  • Tipping helpful service people offline and online
  • Paying for your co-workers cup of coffee in the morning
  • Kids receiving small amounts of money, or even allowance
  • Being able to trade a few hours of your professional time for Karmacoin that are then donated to your favorite cause on KarmaTrade.me (coming soon)
  • Independent artists being paid more money by receiving more payments from more people
  • Paying 30% less for a song because Karmacoin makes transaction fees nearly non-existent.
  • Lending a stranger $10 worth of Karma, knowing that he's got a good reputation with others at the future Karmacoin microloan site, KarmaPay.me
  • Helping someone out with bus fare to get to their first job interview at Karmashare.me or sharing a story about how someone helped you when you needed it most
  • Being able to easily accept small payments from friends, family, co-workers, or customers
This is an untapped industry because traditional payment methods such as credit cards, bank transfers, and checks (even PayPal) make small transactions too expensive from transaction fees, or too slow to be of practical use. For example, if you wish to give 25 cents to someone in person, it's easy. But try doing it online. It becomes prohibitively expensive to the point where you'd need to send 50 cents or more just so the other person can get 25.
Further, Karmacoin can be used by:
  • Companies wanting to provide redeemable rewards to staff
  • Companies wanting to provide redeemable rewards to customers
  • School systems wanting to provide redeemable rewards to students
  • Local governments wanting to provide rewards to their citizens
  • Websites wanting to entice visitors with incentives to visit, interact, or purchase
  • Retail shops wanting to provide incentives to customers to visit the store, browse, or shop
The possibilities in this new industry, which we call the "Good" economy, are endless. Karmacoin aims to be at the forefront of the Good economy by making these micropayments easy, fast, secure, and very, very cheap for everyone involved.
Karmacoin transaction fees are so small they barely register. Here's a comparison of fees:
Credit Card Check Wire Transfer Paypal Bitcoin KARMACOIN
Cost to send 10 cents >100% >100% >100% >100% >100% 0.00%
But the above list of ways in which Karmacoin can be used only scratches the surface of what is possible. As we move towards the Internet of things there will be ways to interact with all of its little components. Each of these components potentially represents a micro-transaction. Accessing, buying, and selling content, services, and other information and a whole world of things that we are unable to think of now.
Billions of transactions performed by hundreds of millions of people each and every day. Many of these transactions fall within the domain of Karmacoin, and that is where we will take the lead in the Good economy.
That is our vision. We hope you'll join us by using, sharing, and giving Karmacoin.
Developers
Please take a look at our development and promotional bounties. We appreciate all you can do to advance Karmacoin and bring it to the next level. We all here believe in Karmacoin and hope you will too. Please help us on our journey. We promise it will be an exciting one!
Thank you to the entire Karmacoin community for being so wonderful and spreading good karma. This will be an exciting journey for us!

Swiss Alps Energy provides the foundation for many future-oriented applications

Swiss Alps Energy provides the foundation for many future-oriented applications
The blockchain community worldwide faces strong headwinds due to the very energy- intensive mining process of crypto currencies and blockchain-based business applications. At the same time, in the Swiss alps, thousands of unused structures are disintegrating due to the fact that today’s spatial planning law does not allow for residential use of these buildings.

https://preview.redd.it/wj2750koryu11.jpg?width=1200&format=pjpg&auto=webp&s=382d5b28923596ee5502b6e0aac8961431dba981
Swiss Alps Energy AG is a distributed ledger-based energy supplier and an operator of flexible modular mining infrastructures that are intended for longterm stationary use. The decentralized distribution of the various facilities allows SAE to offer equally decentralized hosting of individual company blockchains and enables SAE to rent out these infrastructures. Thereby, SAE preserves the aforementioned unused buildings in the Swiss alps and uses them sensibly and without interference with either building structure or the environment.

SAE Target

Out of its unique position as an experienced Swiss provider of blockchain technology and hyperledger-based business applications, Swiss Alps Mining & Energy strives to: • promote blockchain technology and its uses to a broader public • provide clients/third parties the decentralized infrastructure to develeop their own blockchain-based projects • address environmental issues associated with crypto mining worldwide • support the local economy in Swiss alpine areas and facilitate the digital transformation in these areas • Be an electricity supplier using the distributed ledger technology.

The Mission

  • It is of utmost importance that neutral members support the network independently of trading courses. Furthermore, it is important that there are offers that can be paid purely in digital currencies in order to achieve a balance. SAE has developed a sustainable concept to meet these challenges and to address environmental issues.
  • SAE strives to contribute to the digital era and to strenghten the foundation of the groundbreaking blockchain technology. The company aims to advance the digital transformation and bring it to consumers and businesses alike. SAE develops and promotes possibilities and solutions based on distributed ledger technology and seeks to turn digital currencies into an everyday feature.

https://preview.redd.it/k1cqm45pryu11.jpg?width=1200&format=pjpg&auto=webp&s=a5dfb2f199b120c08f226880c519ea38b7b244fe

Market Problem

Over the last few months alone, the Bitcoin Energy Consumption Index has increased by 30%. If bitcoin energy consumption continues to grow at such rates – and no suitable optimization measures are taken – by 2020, bitcoin mining would exceed global electricity consumption by 21 TWh.. In 2017, average costs are estimated to have quadrupled. The mining market is a global business, whereby more than 80% of the mining is done by Chinese-owned businesses. The second largest provider is the Czech Republic with a market share of about 10%. The industry is in an «arms race» and the current crypto currency prices create incentives to add production capacity. There evidently is a need for alternative energy models for the mining of crypto currencies.

SAE Solution

Swiss Alps Energy AG (SAE) strives to promote digital transformaton and sustainability in the Swiss alps. The company is a distributed ledger based energy supplier – SAM Power Plant – and an operator of flexible modular mining infrastructures – SAM Cubes – which are intended for longterm stationary use.
Swiss Alps Energy AG aims to achieve the goal of being energy supplier, energy sales platform and neutral network node provider through its SAM Power Plant, SAM Cubes, and SAM Centers. Swiss Alps Energy AG provides the foundation for many future-oriented applications: financial asset custody and transfer, product tracking through blockchain and IoT in logistics and transportation, electronic records in healthcare, and identity management to simplify the KYC process for any conceivable industry are just a few examples of how distributed ledger technology can be used.

https://preview.redd.it/oo3grwbsryu11.jpg?width=1600&format=pjpg&auto=webp&s=1b84ad0d82f34ffa08b39cade925453866255baa
• SAM Power Plants
By means of direct participation in or the purchase of green power plants such as hydropower plants, photovoltaic systems and wind power plants, SAE does not buy but produce the sustainable and cost-efficient power to operate the SAM Cubes. These power- generating units are the so-called SAM Power Plants.
SAE supports the decentralization and digitization of the energy transition through tokenization and an integrated Internet of Things (IoT) for the purchase or exchange of electricity. Hereby, SAE acts as an independent energy supplier, connecting the interested parties. SAE receives data on the electricity produced and consumed, as well as the respective energy price. This information is stored on the blockchain and therefore transparent and visible.

SAE Introduces SAM Mesh as an Independent ecosystem

  • In order to meet the highest demands in terms of performance, safety and maintenance, Swiss Alps Energy AG develops its own applications based on a derivative of Linux.
  • Every single application, be it in a SAM Cube or SAM Power Plant, initializes and automatically registers itself as a node of a large cluster. Thus, SAM Mesh represents an independent ecosystem.
  • The applications are built to be part of a large network, they are connected at all times and monitored accordingly. In the event of a hardware or software failure, the network will be informed.
  • Classic offline alerts via SMS to the local maintenance service are also integrated, if communication via SAM Mesh is temporarily not possible or restricted.
  • In addition to that, the application is set up and configured in such a way that in the event of hardware failure, it can simply be replaced by plug and play. The system adopts the configurations for the displayed node automatically from the - - SAM Mesh and is fully functional again within a very short time.

SAE Resources

  • Technical innovations and measures to reduce negative impacts on the environment turn small hydropower plants into affordable energy sources that provide environmentally friendly renewable electricity in a decentralized way.
  • Besides the construction of such power plants, there are currently several facilities for sale. Excess energy could be sold to competitors or to the electricity grid, whereby the focus clearly lies on selling excess power to competitors and on promoting Switzerland as a mining location.
  • The operation of subsidized small hydropower plants seems to be interesting as small hydropower plants with a total capacity of less than 1000 kW are exempted from water rates (water tax).

PaaS and IaaS Models

Platform as a Service (PaaS) or Infrastructure as a Service (IaaS) is an important service model in distributed ledger technology. SAM PaaS and SAM IaaS provide the basis for advanced technologies and applications developed on distributed ledger technology. Swiss Alps Energy AG promotes transparent software solutions that cannot be manipulated thanks to a comprehensive infrastructure service, its own innovative power production, as well as sophisticatedconsulting. In particular, finance, transport and medical systems, as well as global identity management are affected. The SAM infrastructure already provides the basis for such disruptive technologies today.

https://preview.redd.it/jtd3zwprryu11.jpg?width=1280&format=pjpg&auto=webp&s=b924eb7bb97ef1459d17a45213b0817498f91fc8

The ICO

Swiss Alps Energy AG (SAE) will hold an Initial Coin Offering (ICO) in June 2018. The funds raised in the ICO will be used to finance the development and expansion of the mining facilities and to acquire holdings in hydropower plants. The SAM token, Sam, is an ERC20 token. It will be used as means of payment within the SAE mining and service universe and will be tradable outside the SAM platform on all relevant exchanges.

Why SAE doin an ICO?

  • Swiss Alps Energy AG strives to raise the capital necessary to set up the corporate structure with an Initial Coin Offering (ICO).
  • It is important to create an operating company that is profitable very quickly. Therefore, the development and establishment of the company’s own decentralized blockchain is financed by further company activities, and the operation of the company is financially secured.
  • Companies and individual persons are target customers for the mining capacities. They may either rent computing power or buy a cube for their ow use.
  • Customers who buy a cube can obtain the necessary power from SAE and operate the cube on SAE’s premises or deploy the cube elsewhere.
  • SAM Cubes can be shipped and installed worldwide. Target customers for the blockchain are companies and end-users..
After the initial development of SAE’s infrastructure and business activities in Switzerland, the expansion into foreign countries, especially in the area of renewable energies, is conceivable and desirable. The ability to pay by using crypto currencies and the settlement process via smart contracts is another novelty that can further help SAE to become the industry leader in the field of blockchain-based business models.

SAM Token

The SAM token needs a transactional blockchain with a powerful system of smart contracts. These smart contracts must be able to ensure that a transaction can be combined with the results of previous transactions to provide auditable and consistent results. To date, Ethereum is the only stable system that has achieved widespread adoption and offers these abilities. Sam tokens are minted via a token sale smart contract and can be held in any Ethereum ERC20 compatible wallet. They will be tradable outside the SAM platform, as they are ERC20 tokens with inherent value in the exchanges. The technical solution of the SAM platform consists of two main elements: • the user facing dashboard and wallet • the smart contracts on the Ethereum blockchain system

Finally

Swiss Alps Energy AG (SAE) strives to contribute to the digital era and to strenghten the foundation of the groundbreaking blockchain technology. The company aims to advance the digital transformation and bring it to consumers and businesses alike. SAE develops and promotes possibilities and solutions based on distributed ledger technology and seeks to turn digital currencies into an everyday feature.

The Strange Birth & History of Monero, Part I: WTF is Bytecoin?

If you are going to do large scale speculation on Monero as a major future currency you need to do a lot of reading and draw your own conclusions. You should never 'invest' in something you don't feel like you understand as thoroughly as you possibly can.
Fortunately, bitcointalk still has the creation of Monero nicely preserved for us to peruse at our leisure. I feel like anyone who is considering owning a significant amount needs to read every post from the initial announcement/discovery of Bytecoin, through the decision to fork and create BitMonero, to the eventual takeover by our current devs to "Monero". You will see a lot of oddities and scenic posts along the way.
Just be careful and don't stare too deeply into the canyon, even if we give you a glass walkway to observe it with: it's very deep.
I'll post a few shortcuts of interest to get you started, and I may update this list a few times so don't mind it if it gets larger. You are welcome to post your own scenic shortcuts in the comments. Today I want to focus on the Bytecoin announcement topic, and look at some of the notable posts there that led to the discovery of the massive premine and the decision to create a Bytecoin fork.
Welcome To Bytecoin, a revolution in digital currency https://bitcointalk.org/index.php?topic=512747.msg5661039#msg5661039

I can see an argument for shortening the schedule relative to bitcoin, but going to one year is probably taking it too far. BTW, it is simple to slow down the schedule, just increase the denominator in the reward formula. If you speed up the blocks to a minute, which I'm not sure is necessarily a good idea, then you need to double the denominator to keep the schedule the same.

Whew!
That's not all that's worth seeing in that thread. I just highlighted some of the most important comments from the first 300, but I surely missed a few. Also, I know that important discussion continued to take place after that as well. Those excerpts only took us to page 15 in the topic and as of writing there are 234 (!!) pages of Bytecoin history to sift through.
The main takeaways should be this though:
  • Cryptonote came out of nowhere in the beginning of 2014, by way of an implementation known as Bytecoin.
  • No one had any idea who created this, and the code was incredibly sharp for a new project indicating that it had been refined for some time before that. (in stark contrast to the mess that was early bitcoin, as one poster put it)
  • The initial excitement over Bytecoin waned as people realized that it had been mined for years and they couldn't figure out anyone who had ever heard of it before then (early 2014). In fact approximately 80% had already been mined by the time the first altcoin enthusiasts heard of it.
  • Some users, including thankful_for_today, propose a fair fork of the technology but everyone was cautious because they don't want to take a piss all over the creators of cryptonote.
  • It is pointed out that the creators of cryptonote actually encourage others to create cryptocurrencies based off it, and do not claim it is a cryptocurrency in itself.
  • It is decided to create "bitmonero" and a new topic for discussion of that begins.
In future installments we will explore the initial days of BitMonero, the hasty launch that ignored the desires and concerns of the community, and the 'takeover' that brought us here to Monero today. Say what you will, but by virtue of having such a strange Chutes & Ladders type past, Monero allows us to focus on what's important: organic community growth and the technology itself. It helps avoid the nasty conspiracy theories and the "who is Satoshi" controversy that surrounds and plagues bitcoin. Some of us own a lot of Monero, but no one was shadow mining it for years before it became public knowledge.
In fact, Monero is so new that there is still time for anyone to be a Monero whale. Looking at the coin price since inception no one can rightly complain they were late to the party at this point. In fact, many of the early adopters paid a heavier price for their coins than we do today. Monero is down off its all time high of around $5.00 a coin during the initial ultra-speculation that surrounded it, and it is only now attaining the next tier of awareness.
The next generation of crypto-currency is here, and once you reduce and collapse all the variables you are looking at possibly the fairest launch in history of a cryptocurrency:
No one has gotten rich yet in the Monero speculation phase, and everyone is still invited to the party.

an "open source" generic offline Linux QR/2key generator and secure cold storage wallet that is small portable quickly acquired and easy to use.

A Bitcoin Root for Linux/Android Phones
A simple Ledger Program and Offline Bitcoin Address/2Key Generator With a Friendly Integrated GUI Written in Linux and Installed on a Cold Bricked Android Phone.
Let me briefly introduce myself, . I am a 10 year Linux PC user (Fedora, Mint, ) which I installed myself through time on various old PCs , Laptops, and Netbooks either online or by usb. . I am trying to find someone who might be interested in writing a: Rooted, Data bricked, Linux Android Phone Program for me,
The program I am proposing and putting forth to the current Linux Open Source, community, for help on would be installed on a unwanted older android phones,
The exact program is “a Linux, “Open Source”, Offline Bitcoin Account Ledger & address QR code generator with a save to memory capability for backups These Backups can be done offline either through tetheusb to offline computer to usb thumbdrive, or to offline printer for paper backup, or without tether, to an already existing external SD card slot if available. And lastly it would have a friendly simple integrated ledger GUI.”
It's a vary small program root and total install, intended to be installed upon a rooted android device which is then immediately wiped clean of the pre existing software file system. The pure Linux open source program would then upon installation as a whole program be vacant and devoid of any files designed to recognize any data transfer capabilities of the physical phone hardware itself” After installation it becomes unaware of such things as bluetooth and wifi, hardware. Thus it cannot transfer data . . The phone is no longer a phone and it does not, nor ever will again' transmit data, for lack of a better term I am calling this cold bricking a phone, . The only means left of communication would be through the screen/camera of a single displayed QR code., This program is intended and permanent unless a re root and re installation is done. The Cold storage function has been "air gapped" The proposed program is so basic in its entire existence. It would easily not over exceed nor ever tax any current cell phone's memory resources or processing requirements. The more minimal and simplistic the entire program the better its meant to be a simple device. Free to the masses in need.
Some of the bottlenecks of the current growing Bitcoin system i can see existing in the world today are
!. It's current lack of a simple use for the common man. 2. It lacks of security for the first time user.
My reason for wanting to make this open source and free and easy is that it might help many people in emergency situations around the world today. Im hoping to make Bitcoin more immediately accessible to this population and the global community as well. This software upon root installation” should provide A safe and secure alternate currency offline cold wallet with quick reliable immediate access to all currently existing online crypto currency exchanges within the global network,. one can then use those existing exchanges to transfer with other entities such as ATM and personal one on one trade as well.and then one can safely secure ones funds and private keys offline. .
This cold bricking physically changes the devices hereafter purpose and function permanently. The old device is now a new device.”
An installed Bitcoin QR code offline generating software program should also have an easy to use user friendly GUI through a Account Books/Ledger GUI. . In the background it would run a Bitcoin Address/2Key offline creation program letting the user have the final 2key QR code image upon users command. It would use camera QR code transfer input and phone screen QR code transfer output The Account Book GUI will prompt the user for type of transfer and amount.
In the end you should have a secure offline cold wallet, portable, with internal offline QR code generating capabilities.
Why I personally want this program, . The Bitcoin phenomena itself has shown that a globally owned currency might be of good use in our world today. Especially in the areas of rescuing localized economic fiat collapse. For a large percentage of citizens living upon within these regional local communities (communities such as Venezuela and Greece 2017). It has in very recent modern times shown that BTC might be be a possible economic rescue tool. The gold and silver community have always believed that precious metals could be used in times of economic collapse, And a long history would dictate their reasoning to be a possible valid and working system. . But as of late there has been a new competitor in this arena of economic relief brought on by the advent of industrial computerization and the world wide web, . This digital global currency system currently BTC may in fact help all of humanity as a tool in stabilizing stressed individuals within collapsing economies. I believe both systems (precious metals and BTC) are valid opportunities and tools for economic rescue, And both can be tried. The Global Digital System is a new one yet to be looked into and fully tried.
In countries today such as those afore mentioned, We as of now currently can find a small percentage of the population experimenting with this global digital currency as refuge while their local fiat slowly collapses around them. This new global BTC currency system may be a large step forwards in protecting many local communities during economic duress in the near future. But it is not widely used amongst these troubled populations.
The problem I see in this new Global BTC System, is in its infancy and growing pains it still lacks ease of use, and availability, which then leads to mistakes in security of assets,
Today, as of this date, . in order to acquire and secure your digital currency in the event of an emergency, You must be tech wise concerning all the avenues of online and digital offline cold storage transfer. You must then purchase an airgapped cold wallet device and you must learn how to use and correctly manipulate this difficult technology, To do this You can download apps that are simply more middlemen in the system of exchange and some not cold secured. , Some apps are better than others, but most fail at differing points. If you do not use and learn how to tranfer amongst apps into total cold storage where you own your private key, Then you can learn make a linux bbotable usb, .and generate offline addresses. then From a laptop or PC, making paper copies on a printer or save offline on digital format, You must then also know the correct ways to transfer and connect this digital data without losing it. (sweeping/importing). For the common man this task is currently daunting and time consuming.
I believe this small open source program largely helps answer the “availability and ease” for most citizens in todays world whether in distressed economies or not, It would also stand to reason that the faster the individuals within an economicly distressed population can get onto a mass globally supported reserve currency, The sooner their people can begin to repair their local system. Once a local community fixes their economic problems the local people by nature while on BTC should then migrate back into the repaired local system. They should migrate naturally back once it becomes more desirable again at a local level, . as long as both systems (global and local) co exist and if the global currency is always freely open to the citizens across the world to invest in at will freely decentralized and anonymously, the global digital currency may have possible avenues of a stable reserve rescue for those in localized economic distress.
Yet, . . as I said it needs at this current time to be more quickly and readily available and easier for the people to use. This is whats lacking in the system as I see it, . . I dont think this new global digital currency is an answer to all and everything, . . . But I do believe it has its advantages. If you have a global wide increased acceptance and use of BTC on a grand geographically diversified scale
What I have done so far , . I have taken an old beloved and reliable android phone laying in my drawer, (a Samsung sch1200) and without rooting it, and by simply downloading two apps from the google play store , I have successfully made it a secure Bitcoin cold storage offline wallet that generates Bitcoin addresses and keys offline, it has a QR code scanner though the phone camera and a screen to display before said QR codes. The device I now have was inexpensive, widely available, and gets easier for me to use for BTC transactions every day, It also securely saves all my BTC offline where I am in charge of protecting those assets myself.
It is an offline bitcoin QR generator and cold storage device.
So if I have done this already why am I asking the Linux community for help.
The one I have right now is tedious as I have hodge podged it together with various apps and must manually create and move my QR data around between apps and ledgers. I Scan a QR code with “QR-Droid” save it manually, cut and paste both adresses and keys. Then save them on a word processor doc. All my addresses key pairs are then saved on individually named docs like unto a digital paper wallet and finally integrated into a single folder for cold storage backup,
As a side note for “random QR code adress and bitcoin key generation” I must, open a previously installed browser “Opera Mini” and the generate the random Bit address and QR key set from the previously saved offline page “bitaddress.org”, (I believe its a simple jave script HTML program, but im not sure),
I have successfully and easily then there after moved funds to my Coinbase and Mycelium accounts and back again, cross platform with no problems and great efficiency and ease, Its totally offline portable code generation and cold storage . IT works well for me, I am in control of my private keys, I also easily back up my data, and I do it often, . every time I generate a new key set I back it up to an external SD , . . and its extreamly portable.
A simple ledger checkbook offline QR cold storage system that creates and manages offline private keys in the background on a reliable no longer used dormant phone, since old phones might fail as in any technology, , (But mine is running strong), It has backup capabilities to either the existing usb tether or if so equipped and my favorite, . external SD card.
In closing I will say, . . .I have the utmost respect for the Linux open source community as a whole,. The only way I would ever pursue this endeavor would be through them, . any other way will not do.
And if by now it falls to nothingness like dreams never written , . . .At least I would urge you all to go to any nice high spot overlooking all people spread across your local community (city or town). Look out upon it, and then ask yourself, what would happen if these my friends below found out they had lost their local fiat currency suddenly all at once today.
And if you don't do that, . . Meh, . .I still have the utmost respect for you anyways, and its all good, . . yeah I just went Crazy today,
Anyways, Thank you for your time. .
P.S. and, . .A Friend I once met along the Bitcoin path recently saw what what I had so crudely made out of an old phone and made a video of it and put it online for me , , it can be found here
https://www.youtube.com/watch?v=0LTu59a5IJA&t=9s
And now I am tired of editing, . I quit, . .it is as it is, . . you'll just have to wade through it people, or get a couple of sentences in and toss it aside, . And .if you got this far, thank you for wading through it.

Yeah, I'll say it: Installing Tails is a goddamned embarrassment.

Buy Bitcoins, they said. Check your Bitcoins from an air-gapped machine with TAILS installed, they said. OK, so, Monday PM I decide, hey, I have a few hours, I'll give it a shot. Here we are and it's Saturday fucking afternoon and I only got Tails to work just NOW.
Sure, I'm a Linux n00b, but your instructions are written in Esperanto. FOUR "live USB pen" automatic installers later, nothing installs Tails with persistence. The only way I got it to install was somehow deciding (because it's sure as hell not noted anywhere) to just blargh the .ISO's files onto the USB created by the Live Linux installer. Er..... okay.
So I got Tails working, then installed it to a new USB using the Tails Installer. Very Fight Club, you guys, that's so meta. Wait. Are you guys seriously advising people to get Tails from a friend? This is your adoption strategy?? Like this is supposed to go viral on the street? Should I buy a Fedora and try to pimp Tails to random people??
I use a Ledger Wallet, which is a hardware Bitcoin wallet. It only runs on Chrome. So... I can't install Chrome on Tails???? Not even a local copy?
I'd go back to Linux Mint, but good luck getting persistence to work on Mint. I couldn't figure it out. Why do I have to be a goddamned command-line ninja to get anything working? With a UI like Mint's, seriously, I have to get persistence working from a Windows box??
If anyone knows of a utility or a magic web page with actual instructions to get this working, it would be worth definite Gold to me.

Just migrated from Win 8.1 to Mint 17.1 - all my problems have gone away

After months of frustration with Win 8.1, I finally got fed up and dl'd the latest version of Mint, connected up a spare SSD, and installed it over an old Win 7 partition. Issues I had with Win 8.1 were crackling audio over usb to my o2\odac\Senheisser HD600, random internet access issues with my VPN, restarts for OS updates, and driver issues with my Trezor (Bitcoin hardware wallet). In Mint all of these issues have been resolved, and I was amazed to discover that even Steam is now on Linux with some of my favourite games such as Portal 2, Kerbal Space Program, Civ V, LIMBO, and most importantly, Euro Truck Simulator 2! I was further amazed when I plugged in my media drive and found I could listen to my FLAC music and watch all my movies out of the box. 2015 is going to be a great year!

New Ledger won't connect to Linux, works on Windows

My Nano S arrived. 1. I have browser support to OFF. 2. I installed the Bitcoin Wallet App. 3. I'm using original cable and tried multiple other cables and ports. 4. Tried on Windows 10 and it works. 6. Trying it on Linux Mint 18.3
Issue: I can't connect ledger, I set it up but it won't connect to a wallet app nor will my PC recognize it as a device. I tried it on Windows and it worked.
Question s:
  1. How can I connect my Ledger Nano S To Linux?
  2. Why is it so hard to find a contact form and contact Ledger? It's like they are deliberately making it harder.

(We're giving away 200,000,000 Karmacoin over the next few days to everyone. See the "How Do I Get Karmacoin?" section below.)
What is Karmacoin?
Karmacoin is a new way to show your family, friends, and others that you appreciate them. Think of it as a "Like" button that you can take anywhere. It's a P2P currency, like Bitcoin. You can use it to share with those you care about. We call it Give+Karma, because when you do good, good comes back to you.
You can think of Karmacoin as another way to say thanks. When you Give+Karma you're sharing your experience in a community where the little things matter. Random acts of kindness, caring about what others have to say, showing appreciation, being happy, doing good things, and enjoying life. It's the little things that count. And that's why we developed Karmacoin.
We're currently expanding our cause not just around the internet but around the world. We shared a summary of our business plan and project schedule with our community so that everyone knows what we're up to. Our goal is to become the #1 way for people to reward others, and be rewarded themselves. Karmacoin can be thought of as an incentive for more people to:
Our vision is a world where hundreds of millions of people around the world use Karmacoin everyday.
How Do I Get Karmacoin?
You can get Karmacoin from others who share it, or purchasing it from a trusted exchange like MintPal using your Bitcoin. In a few days we'll be announcing an easy way to buy Karmacoin using Paypal.
Luckily, to celebrate our new main website and a new place where you can share stories about people doing good things called Karmashare, both launching on March 20, we are giving away 200,000,000 Karmacoin so you can try it out!
**Be sure to subscribe to the Karmacoin subreddit **
Be sure to download the Wallet for Windows, Mac, or Linux. (We're updating the graphics so don't be alarmed! It's the correct version.) Once you've installed this, you can click on the Receive tab, highlight the first row, and click the Copy button at the bottom. This is your new Karmacoin address ("Karmaddress") you can use to receive Karmacoin. (You can also send by clicking on the Send tab and entering the recipient's Karmaddress.) We're working on an easy-to-understand video tutorial now, and will be posting that for the community.
If someone is sending you Karma you can give them your new Karmaddress and you should receive it anywhere from 15 seconds to a few minutes.
Our website will soon offer some instructions of how to get and use Karmacoin. Stay tuned...
The Karmacoin Vision
We believe that the micro-transaction economy is based on kindness, sharing, small donations, microloans, tipping, and the little things that can make life wonderful and people feel appreciated, including:
  • Online tips to other internet users who deserve a little recognition
  • Tipping helpful service people offline and online
  • Paying for your co-workers cup of coffee in the morning
  • Kids receiving small amounts of money, or even allowance
  • Being able to trade a few hours of your professional time for Karmacoin that are then donated to your favorite cause on KarmaTrade.me (coming soon)
  • Independent artists being paid more money by receiving more payments from more people
  • Paying 30% less for a song because Karmacoin makes transaction fees nearly non-existent.
  • Lending a stranger $10 worth of Karma, knowing that he's got a good reputation with others at the future Karmacoin microloan site, KarmaPay.me
  • Helping someone out with bus fare to get to their first job interview at Karmashare.me or sharing a story about how someone helped you when you needed it most
  • Being able to easily accept small payments from friends, family, co-workers, or customers
This is an untapped industry because traditional payment methods such as credit cards, bank transfers, and checks (even PayPal) make small transactions too expensive from transaction fees, or too slow to be of practical use. For example, if you wish to give 25 cents to someone in person, it's easy. But try doing it online. It becomes prohibitively expensive to the point where you'd need to send 50 cents or more just so the other person can get 25.
Further, Karmacoin can be used by:
  • Companies wanting to provide redeemable rewards to staff
  • Companies wanting to provide redeemable rewards to customers
  • School systems wanting to provide redeemable rewards to students
  • Local governments wanting to provide rewards to their citizens
  • Websites wanting to entice visitors with incentives to visit, interact, or purchase
  • Retail shops wanting to provide incentives to customers to visit the store, browse, or shop
The possibilities in this new industry, which we call the "Good" economy, are endless. Karmacoin aims to be at the forefront of the Good economy by making these micropayments easy, fast, secure, and very, very cheap for everyone involved.
Karmacoin transaction fees are so small they barely register. Here's a comparison of fees:
Credit Card Check Wire Transfer Paypal Bitcoin KARMACOIN
Cost to send 10 cents >100% >100% >100% >100% >100% 0.00%
But the above list of ways in which Karmacoin can be used only scratches the surface of what is possible. As we move towards the Internet of things there will be ways to interact with all of its little components. Each of these components potentially represents a micro-transaction. Accessing, buying, and selling content, services, and other information and a whole world of things that we are unable to think of now.
Billions of transactions performed by hundreds of millions of people each and every day. Many of these transactions fall within the domain of Karmacoin, and that is where we will take the lead in the Good economy.
That is our vision. We hope you'll join us by using, sharing, and giving Karmacoin.
Developers
Please take a look at our development and promotional bounties. We appreciate all you can do to advance Karmacoin and bring it to the next level. We all here believe in Karmacoin and hope you will too. Please help us on our journey. We promise it will be an exciting one!
Thank you to the entire Karmacoin community for being so wonderful and spreading good karma. This will be an exciting journey for us!
