Running A Full Node - Bitcoin

BTC Node. Need help with Ubuntu and BTC core program. To the Linux experts here in reddit.

The good thing of loosing a post, is that you have to retype everything and this means that you are able to shorten the post.
So. TLDR, I have 2 hdd, 80gb and 320, the second one has only, all the Blockchain info, from another already running node. I am not able to tell BTC Core program that the files are already there so he does not need to download 300gb. After hours of Google and linux forums, I am stuck in this issue. Every time I type "bitcoin-qt" on my terminal, it shows as a first download. Any help will be appreciate.

Full story.
English is not my first language, and this is being typed for second time (please have mercy on my grammar or misspelling mistakes), because I posted the question on linux subreddit nobody give a f..... so I decided to bring it here, posted a short post with the link and the automatic bot deleted because the of the link. I erased both the linux and the bitcoin post, and made a third one new, here, with plain text, copy pasting the info from the linux post. Never appeared on the "new" section of this sub. So hours of typing lost, and here we are.
Old Notebook. 80gb drive, and noob to Linux. Although I have some pc and logic knowledge, installed MINT due to a recommendation from a Bitcoin community, but since I have a friend with an already running node, with Ubuntu switched to this one, just to have the same system.
Once Ubuntu installed, on the 80gb and pc running, I copy and pasted the whole bitcoin folder from my friends pc to my 320 gb. Up to here all was good. But here is the problem

My friend, who does not understand nothing about linux, is owner of a company and has an IT guy who made everything for him, but would not be willing to help me a lot, (just to be good with his boss but right now it is not reachable for me), but when we where on my pc he told me that Linux is very sensitive to ports, in other words, a small usb change, will do a program to loose the path for the files. SO, instead of using the 320gb disk on USB i installed on this notebook second Hdd bay (its an old high end laptop with 2 sata connectors), he was able to set the program and everything went well for a couple of hours, Bitcoin Core program started synchronizing, downloading very little info.

I needed to turn of the pc to move it, so closed the program (waited until bitcoin core program told me was safe to) and turn it off, then turn it on again, and the problem was there, bitcoin core program started trying to download the whole blockchain in the spare 2gb of the 320 gb disk.
So what it seemed to happen is that even when the disk is installed on a sata bay from the motherboard, as I did not installed ubunutu with this disk connected it's route (adress?) is dinamyc and that is why BTC Core Program lost the files and does not recognize it.
After hours of google, linux forums and "askubuntu" i was able to, mount the 320gb disk, first editing the fstab ( i followed the guide in "askubuntu.com/questions/125257/how-do-i-add-an-additional-hard-drive") by the way. Trying to use VIM editor was a pain, it is REALLY difficult to type something there, and save it without pressing a wrong key. I had to cancel and start over at least a dozen times (plus reading several guides), but still was not able to mount the disk (Actually after following the steps, the hdd (320) disappeared from the GUI). went back, erased, and the did the NANO steps, and I THINK that now the hard drive it is fixed (before, any change,when restarting the second hdd took some time to appear, now it seems that is mounted and to a fixed adress). Well, after mounting the hdd, I tryed to call the bitcoin-qt and the initial download page appear and again tries to download from the initial block. I searched over hours "file association in ubuntu", "program files path" etc etc and the only thing I found is how to set up the desired software to open a file.

For you to understand my mess, when I did the "user:user" thing, I did not understand completely what I was doing, (yes I had to be in sudo) BUT i think I managed to did the correct thing as both hdd are shown in the Ubuntu GUI.

Some additional data is
Both hard drives are formated in Ext4
I have (I think that) a fstab.bak before any changes

I knwo that linux users sometimes ask for details on the system, just tell me the commands and i can run them to stick any info needed.

Thanks for the help in advance.

Full Node - bitcoin-qt Memory Pool is "N/A"

Hi, I'm running bitcoin-qt 19.0.1 on Linux Mint and have had no problems running it until the other day when we had a power outage, and the node was killed without a clean exit. Now everytime I run it, the 'current number of transactions' and 'memory usage' under the Mempool section of the bitcoin-qt debug window says 'N/A', and has remained so for a few days. The number of connections always increases to a normal amount, and I can see all my peers. The blockchain info is updating with the latest blocks and timestamps as well, so the connections seem to be fine, but the mempool info is screwed up.
Does anyone know what this means, and how to get it back to its former state?

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.

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.

Secure paper wallet tutorial

This is my handout for paranoid people who want a way to store bitcoin safely. It requires a little work, but this is the method I use because it should be resistant to risks associated with:
  1. Bad random number generators
  2. Malicious or flawed software
  3. Hacked computers
If you want a method that is less secure but easier, skip to the bottom of this post.
The Secure Method
  1. Download bitaddress.org. (Try going to the website and pressing "ctrl+s")
  2. Put the bitaddress.org file on a computer with an operating system that has not interacted with the internet much or at all. The computer should not be hooked up to the internet when you do this. You could put the bitaddress file on a USB stick, and then turn off your computer, unplug the internet, and boot it up using a boot-from-CD copy of linux (Ubuntu or Mint for example). This prevents any mal-ware you may have accumulated from running and capturing your keystrokes. I use an old android smart phone that I have done a factory reset on. It has no sim-card and does not have the password to my home wifi. Also the phone wifi is turned off. If you are using a fresh operating system, and do not have a connection to the internet, then your private key will probably not escape the computer.
  3. Roll a die 62 times and write down the sequence of numbers. This gives you 2160 possible outcomes, which is the maximum that Bitcoin supports.
  4. Run bitaddress.org from your offline computer. Input the sequence of numbers from the die rolls into the "Brain Wallet" tab. By providing your own source of randomness, you do not have to worry that the random number generator used by your computer is too weak. I'm looking at you, NSA ಠ_ಠ
  5. Brain Wallet tab creates a private key and address.
  6. Write down the address and private key by hand or print them on a dumb printer. (Dumb printer means not the one at your office with the hard drive. Maybe not the 4 in 1 printer that scans and faxes and makes waffles.) If you hand copy them you may want to hand copy more than one format. (WIF and HEX). If you are crazy and are storing your life savings in Bitcoin, and you hand copy the private key, do a double-check by typing the private key back into the tool on the "Wallet Details" tab and confirm that it recreates the same public address.
  7. Load your paper wallet by sending your bitcoin to the public address. You can do this as many times as you like.
  8. You can view the current balance of your paper wallet by typing the public address into the search box at blockchain.info
  9. If you are using an old cell phone or tablet do a factory reset when you are finished so that the memory of the private keys is destroyed. If you are using a computer with a boot-from-CD copy of linux, I think you can just power down the computer and the private keys will be gone. (Maybe someone can confirm for me that the private keys would not be able to be cached by bitaddress?)
  10. To spend your paper wallet, you will need to either create an offline transaction, or import the private key into a hot wallet. Creating an offline transaction is dangerous if you don't know what you are doing. Importing to a client side wallet like Bitcoin-Qt, Electrum, MultiBit or Armory is a good idea. You can also import to an online wallet such as Blockchain.info or Coinbase.
Trusting bitaddress.org
The only thing you need bitaddress.org to do is to honestly convert the brainwallet passphrase into the corresponding private key and address. You can verify that it is doing this honestly by running several test passphrases through the copy of bitaddress that you plan on using, and several other brainwallet generators. For example, you could use the online version of bitaddress, and brainwallet and safepaperwallet and bitcoinpaperwallet. If you are fancy with the linux command line, you can also try "echo -n my_die_rolls | sha256sum". The linux operating system should reply with the same private key that bitaddress makes. This protects you from a malicious paper wallet generator.
Trusting your copy of bitaddress.org
Bitaddress publishes the sha1 hash of the bitaddress.org website at this location:
https://www.bitaddress.org/pgpsignedmsg.txt
The message is signed by the creator, pointbiz. I found his PGP fingerprint here:
https://github.com/pointbiz/bitaddress.org/issues/18
"527B 5C82 B1F6 B2DB 72A0 ECBF 8749 7B91 6397 4F5A"
With this fingerprint, you can authenticate the signed message, which gives you the hash of the current bitaddress.org file. Then you can hash your copy of the file and authenticate the file.
I do not have a way to authenticate the fingerprint itself, sorry. According to the website I linked to, git has cryptographic traceability that would enable a person to do some research and authenticate the fingerprint. If you want to go that far, knock yourself out. I think that the techniques described in this document do not really rely on bitaddress being un-corrupt. Anyway, how do we know pointbiz is a good guy? ;-)
There are a lot of skilled eyes watching bitaddress.org and the signed sha1 hash. To gain the most benefit from all of those eyes, it's probably worthwhile to check your copy by hashing it and comparing to the published hash.
"But we aren't supposed to use brainwallets"
You are not supposed to use brainwallets that have predictable passphrases. People think they are pretty clever about how they pick their passphrases, but a lot of bitcoins have been stolen because people tend to come up with similar ideas. If you let dice generate the passphrase, then it is totally random, and you just need to make sure to roll enough times.
How to avoid spending your life rolling dice
When I first started doing this, I rolled a die 62 times for each private key. This is not necessary. You can simply roll the die 62 times and keep the sequence of 62 numbers as a "seed". The first paper address you create would use "my die rolls-1" as the passphrase, the second would be "my die rolls-2" and so on. This is safe because SHA256 prevents any computable relationship between the resulting private key family.
Of course this has a certain bad security scenario -- if anyone obtains the seed they can reconstruct all of your paper wallets. So this is not for everyone! On the other hand, it also means that if you happen to lose one of your paper wallets, you could reconstruct it so long as you still had the seed.
One way to reduce this risk is to add an easy to remember password like this: "my die rolls-password-1".
If you prefer, you can use a technique called diceware to convert your die rolls to words that still contain the same quantity of entropy, but which could be easier to work with. I don't use diceware because it's another piece of software that I have to trust, and I'm just copy/pasting my high entropy seed, so I don't care about how ugly it is.
Why not input the dice as a Base 6 private key on the Wallet Details tab?
Two reasons. First of all, this option requires that you roll the die 99 times, but you do not get meaningful additional protection by rolling more than 62 times. Why roll more times if you don't have to? Second, I use the "high entropy seed" method to generate multiple private keys from the same die rolls. Using the Base 6 option would require rolling 99 times for every private key.
I'm a big nerd with exotic dice. How many times to roll?
Put this formula in Excel to get the number of times to roll: "=160*LOG(2,f)" where f = number of faces on the die. For example, you would roll a d16 40 times. By the way, somewhat unbelievably casino dice are more fair than ordinary dice
The "Change address" problem:
You should understand change addresses because some people have accidentally lost money by not understanding it.
Imagine your paper wallet is a 10 dollar bill. You use it to buy a candy bar. To do this you give the cashier the entire 10 dollar bill. They keep 1 dollar and give you 9 dollars back as change.
With Bitcoin, you have to explicitly say that you want 9 dollars back, and you have to provide an address where it should go to. If you just hand over the 10 dollar bill, and don't say you want 9 dollars back, then the miner who processes the transaction gives 1 dollar to the store and keeps the remainder themselves.
Wallet software like Bitcoin-Qt handles this automatically for you. They automatically make "change addresses" and they automatically construct transactions that make the change go to the change address.
There are three ways I know of that the change problem can bite you:
  1. You generate a raw transaction by hand, and screw up. If you are generating a transaction "by hand" with a raw transaction editor, you need to be extra careful that your outputs add up to the same number as your inputs. Otherwise, the very lucky miner who puts your transaction in a block will keep the difference.
  2. You import a paper wallet into a wallet software and spend part of it, and then think that the change is in the paper wallet. The change is not in the paper wallet. It is in a change address that the wallet software generated. That means that if you lose your wallet.dat file you will lose all the change. The paper wallet is empty.
  3. You import a paper wallet into a wallet software and spend part of it, and then think that the change is in the change address that the wallet software generated. If the transaction did not need to consume all of the "outputs" used to fund the paper wallet, then there could be some unspent outputs still located at the address of the paper wallet. If you destroyed the paper wallet, and destroyed the copy of the private key imported to the wallet software, then you could not access this money. (E.g. if you restored the software wallet from its seed, thinking all of the money was moved to the wallet-generated change addresses.)
For more on this, see here
The hot paper wallet problem
Your bitcoin in your paper wallet are secure, so long as the piece of paper is secure, until you go to spend it. When you spend it, you put the private key onto a computer that is connected to the internet. At this point you must regard your paper wallet address as hot because the computer you used may have been compromised. It now provides much less protection against theft of your coins. If you need the level of protection that a cold paper wallet provides, you need to create a new one and send your coins to it.
Destroying your paper wallet address
Do not destroy the only copy of a private key without verifying that there is no money at that address. Your client may have sent change to your paper wallet address without you realizing it. Your client may have not consumed all of the unspent outputs available at the paper wallet address. You can go to blockchain.info and type the public address into the search window to see the current balance. I don't bother destroying my used/empty paper wallet addresses. I just file them away.
Encrypting your private key
BIP 0038 describes a standardized way to encrypt your paper wallet private key. A normal paper wallet is vulnerable because if anyone sees the private key they can take the coins. The BIP38 protocol is even resistant to brute force attacks because it uses a memory intensive encryption algorithm called scrypt. If you want to encrypt your wallets using BIP38, I recommend that you use bitcoinpaperwallet because they will let you type in your own private key and will encrypt it for you. As with bitaddress, for high security you should only use a local copy of this website on a computer that will never get connected to the internet.
Splitting your private key
Another option for protecting the private key is to convert it into multiple fragments that must be brought together. This method allows you to store pieces of your key with separate people in separate locations. It can be set up so that you can reconstitute the private key when you have any 2 out of the 3 fragments. This technique is called Shamir's Secret Sharing. I have not tried this technique, but you may find it valuable. You could try using this website http://passguardian.com/ which will help you split up a key. As before, you should do this on an offline computer. Keep in mind if you use this service that you are trusting it to work properly. It would be good to find other independently created tools that could be used to validate the operation of passguardian. Personally, I would be nervous destroying the only copy of a private key and relying entirely on the fragments generated by the website.
Looks like Bitaddress has an implementation of Shamir's Secret Sharing now under the "Split Wallet" tab. However it would appear that you cannot provide your own key for this, so you would have to trust bitaddress.
Durable Media
Pay attention to the media you use to record your paper wallet. Some kinds of ink fade, some kinds of paper disintegrate. Moisture and heat are your enemies.
In addition to keeping copies of my paper wallet addresses I did the following:
  1. Order a set of numeric metal stamps. ($10)
  2. Buy a square galvanized steel outlet cover from the hardware store ($1)
  3. Buy a sledgehammer from the hardware store
  4. Write the die rolls on the steel plate using a sharpie
  5. Use the hammer to stamp the metal. Do all the 1's, then all the 2's etc. Please use eye protection, as metal stamp may emit sparks or fly unexpectedly across the garage. :-)
  6. Use nail polish remover to erase the sharpie
Electrum
If you trust electrum you might try running it on an offline computer, and having it generate a series of private keys from a seed. I don't have experience with this software, but it sounds like there are some slick possibilities there that could save you time if you are working with a lot of addresses.
Message to the downvoters
I would appreciate it if you would comment, so that I can learn from your opinion. Thanks!
The Easy Method
This method is probably suitable for small quantities of bitcoin. I would not trust it for life-altering sums of money.
  1. Download the bitaddress.org website to your hard drive.
  2. Close your browser
  3. Disconnect from the internet
  4. Open the bitaddress.org website from your hard drive.
  5. Print a paper wallet on your printer
  6. Close your browser

Want to help ReddCoin? Remember to be nice to newcomers!

Hi /ReddCoin!
Want to help ReddCoin? Remember to be nice to newcomers.
Look at the current road map. With PoSV growing out of its infant stages, with the Social Tip Platform coming in a few months, along with the Social X whitepaper, Android/iOS/web wallets, Social Broadcast, etc., there are going to be a lot of people lurking /ReddCoin.
Some of them are going to be asking questions. A lot of these questions are going to be questions you already know the answer too, but you have to remember that newcomers will be asking these questions because they don't know the answer to them.
Be nice to them. Don't tell them, "the search button is right there." Don't tell them, "search this sub, there's been a lot of posts about this already." Don't tell them anything like that. This is horrible customer service. ReddCoin can't be the Social Currency if its community isn't social.
But I'm also a realistic person. It can get really tedious to type the same things over and over again. So what I've done is typed everything out for you already. I've preformatted the text as well.
So if someone new asks a question that's in this thread, all you have to do is refer to this post (or refer them to this post in general), and then copy and paste the answer. All the formatting is already done for you, so it's that simple!
Want to test it out? Copy and paste random entries below and enter in the comments below to see how easy it is! Feel free to change any grammer, words, etc. Tailor it the responses to your style! As long as people's questions get answered, :).
Do you see a broken link, typo, or incorrect information? Want to add in another question and answer entry? Let me know! Tips will be given!

Dev update 2016-03-18

neurocis (main dev) posted on BitcoinTalk:
It has been a while since I have posted an update from the development side as I am engaged in a few large paid projects projects together with helping my wife launch her business. Suffice it to say that I am still active and although I have not had as much time as I have desired to donate to PIGGY things are progressing, although slowly.
It has become apparent that my personal development environment has become dated and insufficient for both this project as well as freelance work I desire to take on. As such I have recently invested in new hardware which I expect to have up and running by end of month (hoping shipping from HK to Canada is the same as I remember it being).
My focus is still on the implementation of EasySend and Piggy Wallet Services (co-pay port) with an anticipated hard fork to implement OP_RETURN to enable coloured coins down the road. A containerized build environment has been setup for Linux and Windows daemons with active work being done for Mac. I hope to be able to "build the builder" for Qt wallets once this new hardware arrives. The Linux builder also supports both traditional Intel PCs as well as ARM (Raspberry Pi) as I have been playing with PIGGY on the Pi and a web interface for a minting hardware wallet aka "PiggyMints".
A Docker container of the daemon has been pushed to the TeamPiggyCoin GitHub, but it is more of a building block for Piggy Wallet Services and PiggyMints than a user friendly wallet (unless you like to talk RPC and CLI, then have at it!). Over the next few weeks expect most announcements from me to be involving the delivery of core services (aka infrastructure) as we build the foundation for other services to leverage (EasySend, coloured coins and games which use PIGGY as medium of exchange).
I also want to thank you all for your support of PIGGY and keeping the idea of "crypto for kids" alive and well.

Is anyone else having this issue?

Alright, I'm looking to get into Bitcoin. I'm currently using linux mint, so I downloaded the .tar.gz file and extracted it to my desktop, accessed the bitoin-qt file, and while it was loading, particularly right after loading my wallet, the error message "Failed to read block" comes up. I have tried deleting and re-downloading it multiple times to no avail. TL;DR: error "Failed to read block" not solved by re-installing. Wat do.
EDIT: Yes, I googled the error, and didn't get a good answer. I eventually had to resort to bing, eternally staining my soul. Anyone help?

[Help] Free space by moving bitcoin-qt to separate drive

I am currently using bitcoin-qt on Linux Mint, but it is taking up most of my SSD, and growing. Is there a way that I can make bitcoin-qt store its data on a separate drive so that I can free space?

Questing regarding recovering wallet

So I run linux now and found the APPDATA bitcoin folder on an old XP harddrive, containing wallet.dat (it is old about 3.8 years old - maybe different format or something is issue?)
I'm farily certain I have some coins from the few days I mined, at least one for sure yet I cannot find it. I copied the wallet.dat from my old XP HD then pasted into the ~/.bitcoin directory in my Linux Mint 15 installation, launched bitcoin-qt using both -rescan and -reindex still with no balance once the block is done downloading. I have even considered getting pywallet.py and extracting the addresses of all my ewallets in wallet.dat and recompiling it, but would like to avoid that if possible..

Questions Answers
Most proponents of Bitcoin seem to believe that there will be a point where one coin exceeds a value of $100 or even $1000. Sure, that is definitely possible and I can accept that it may happen one day. However, since each coin has this intrinsic potential value.. why would anyone spend them on trivial stuff like food now? How can you spend something that you believe will continue to grow in value effectively to infinity? That seems like a fair complaint to me, in general. In practice, and as opposed to Krugman's thoughts on the matter, we have many thousands of happy Bitcoin transactors, I think people like to spend their bitcoins with others, give them away, and use them for things. I do know some Bitcoin businesses that try never to spend their coins. That said, we have had some periods like last year where EVERYBODY wished they'd spent their coins.. To my mind volatility is a worse 'evil' than being deflationary. As I said above, I think most government economists wish an inflationary currency (and many bitcoiners hate this, and talk a lot about how much they hate it), but I think there's definitely a place in the world for a deflationary value system. An interesting thought experiment for you -- if you forked the Bitcoin blockchain and changed issuance so that it tracked say, USD or USD/EUR inflation rates for issuance, would it have the same uptake or not?
Every once in a while I hear stories about security breaches including 240,000 bitcoins that went missing the other month. How do you ensure security of account holders funds? The practical security aspects of running Bitcoin businesses are a REAL need, and it's something we want to help on with advice, and possibly opt-in certification at some point. I say more about this elsewhere in the AMA.
Furthermore, most sites I've came upon that sell goods seem poorly managed and difficult to use. Is there a Bitcoin equivalent to sites like Ebay and Amazon? Re: bitcoin site usability -- I agree, it's often terrible! I'm not sure why this is, except to say that bitcoins make transacting online so easy that even people who can't afford a designer can do it.
A: How does the intrinsic non-fiat nature of the currency affect its susceptibility to market fluctuation? I.E. Better or worse stability than fiat currency? So far, because market cap is so low, (Roughly $100mm of value), Bitcoin exchange rates are highly susceptible to people pushing it around. This is really tough for everyone. There are a bunch of businesses that might not be viable until you have some exchange rate certainties that extend beyond a short (one day-ish) window.
B: What can be done to improve the resistance to massive fluctuations in value stemming from exchange market manipulation or normal use? There are some macro-economic things that could be done, like exchanges publishing all trades to a central area, and implementing locks if prices rise / fall too suddenly, but those all have their own effects to consider. I think the fundamental thing to do is help Bitcoin acceptance and uptake grow, increasing the size of the pie until there are a much smaller number of parties that could push the price around.
C: Is there anything that can be done to the standard to improve stability or is it all up to the markets to implement safeguards? So, we all do have a part in that stabilization for sure. There's also the angle of creating whole supply chains that are bitcoin denominated -- paying our staff in Bitcoins only is an attempt to work on that angle.
What do you say to people that claim Bitcoin is nothing but a pump-and-dump pyramid scheme designed to benefit it's creators? That they're sitting on a huge pile of bitcoins obtained by them before the currency was made available to the public when mining was far easier then dumping huge batches of Bitcoins destroying the price over and over again to enrich themselves and fuck everybody else? And that they get more chumps into the system to inflate the price again, by going around the internet and promoting Bitcoins as an alternative currency rather than a complete fraud? This borders on the troll-ish, but I will say that the Bitcoin network autosizes coin generation based on how many people wish to do it. That is, people opt in to make the coins and secure the network. Nobody is forced to.
Is the Bitcoin Foundation a non-profit, tax-exempt organization in the United States? Who among the directors and the board has experience running a non-profit? Why is the ED also a member of the board? How does the ED have the time to run the organization given his obligation to CoinLab? Why haven't I seen any of the involved parties at either of the last two Bitcoin conferences? Can we get somebody who isn't a white male involved? We're a 501(c)6, Washington DC Nonprofit.
I have experience launching a non-profit, hence my job.
ED's typically get a salary and work full time at the job; we didn't know if we'd have budget to pay someone who could operate such a thing, so we went with this structure. I anticipate that I will step down from being the ED at the earliest moment we know we have someone better to do it; running CoinLab is plenty of work for me.
Our assistant director Lindsay Holland is not a white male.
In general, Bitcoin is a white male sausage-fest, though. I urge you and all Bitcoiners everywhere to work on changing that.
What is the future of bitcoins? Do you think they will ever make government-issued currency obsolete? I don't know the future of Bitcoin, but I hope that I and the Foundation are a part of it!
I don't believe Bitcoin will ever obsolete a government currency, but I only speak for myself when I say that. Bitcoin is a fascinating and novel technology with a HUGE number of potential benefits to the world, so I'm into it. I don't see a government wishing to cede control of its currency to anything like the technocratic / consensus model that Bitcoins are governed by, though.
That said, I do hope that Bitcoins will be able to help people in areas of the world that need better money features. Mpesa is a great example of something that helps Kenyans (and people from a few other countries) by changing how money is used. Bitcoin has the potential to help people like that, all over the world, whether or not the 'market' is large enough in that country.
I personally think that sort of thing is SUPER exciting.
Could you describe the bitcoin foundation for me? Sure! It's a trade organization, member-driven. Its goal is to promote, protect and help standardize Bitcoin. Our initial goals are to provide funding for the core development team, run a 2013 Silicon Valley Conference, and create some opt-in certification methods and best practices for businesses dealing with Bitcoin.
Join us.. :)
Standardize? I can tell you hate our goals, so I won't spend a long time trying to convince you. But, I will say that businesses often need a long, secure timeframe to make investment decisions, and they need to have some sense that what they work on or invest in will be roughly similar at the end of their investment to the beginning.
Why do you want to "standardize"? For instance, imagine ebay deciding to take bitcoins. The person-hours to get that done inside ebay are staggering to imagine, from wallet scalability issue to accounting treatments, refunds, ... It would be a major endeavor.
What gives you that authority? It would be great for bitcoin if ebay took bitcoins. Seriously great, but they can't right now until they feel there is some generally stable path going forward.
Why is the core development team so deserving of funding when they can't even make a decent client? You might hate everything about that, and that's cool. I urge you to go ahead, fork the code, advocate as much as you like for something else. Bitcoin's free, both the protocol and the software. Nobody is stopping you.
Is there any legal action to be done if someone steals your bitcoins? Yep, if you're in the US, file a police report, and call FBI Cybercrimes division.
As an individual member of the Bitcoin Foundation, what do I get? Any perks or privileges? Email aliases, voting rights, a newsletter, etc? Or are these memberships mostly a way of providing financial support to the foundation? The bylaws are up now, so you can read in great detail what the organization will provide its members: Link to github.com
In short, though, rights to vote people on / off the board of the Foundation, soon access to private forums, probably discounts to the bitcoin 2013 conference, happiness at supporting the dev team.
I would like to provide email aliases, we've got Patrick and Jon working on any possible gotchas there, though.
Many aren't taking bitcoin seriously because of the security issues some have had. What steps are you taking to legitimize this currency? Like Jeff says below, I would distinguish between fundamental protocol security and security practices.
Bitcoins fundamental protocol security seems pretty good at this point; I'm sure we'll all be keeping an eye on that quite intently into the future.
Practical Security has been, largely, terrible in the Bitcoin space for most businesses, Mt. Gox perhaps excepted. The amount of work it takes to secure 80 byte strings that may be valued in the million dollar range is non trivial. Think securing missile codes as to the level of security needed.
Many bitcoin businesses can't afford (or don't wish to) this sort of security. I'm hoping we can provide some tools and pointers for these businesses and their users to help people understand what they're getting into when they transact with a bitcoin business, and what their risks are.
The Bitcoin Foundation Membership (VIP) fees are definitely disproportionate. Why? Are we now heading for a two-tier bitcoin community? We got requests from large supporters to make a more expensive membership tier. I'm slow, but not so slow that I said 'no'.
I'm slow, but not so slow that I said 'no'. - So you said 'YES'? Someone said "Please make higher corporate member fees: Linux Foundation Top Tier member fees are $500k. Your plan is too low."
I said "OK, Thank you for that advice. We should do that."
Is the foundation primarily focused on US or also europe and the rest of the world? Right now Jon Matonis is considered our "Europe Expert" on the board. There's a huge amount of work to do just in keeping track of how Bitcoin is categorized and regulated around the world. I would expect the Foundation to put some time and energy into helping with that process, but it's not our first goal.
What would you or the Fundation do if the government declares Bitcoin ilegal? Advocate that such a thing is silly, unenforceable, and counterproductive.
Thats no answer to the question. Have you got any plans for the "unthinkable"? That really is what I would do. What do you suggest?
What are your thoughts on transparency of the foundation? How much revenue is there and how it is spent, will that info be public? We're aiming to be highly transparent. I proposed today that we publicize our cold wallet public keys so that people can check our balances. This got pushed back a month while we work on some logistics. I will follow up about this, though. I think having auditable books from day one is really cool.
What are your thoughts on fiat currency? I love it and wish more of it. I'm totally grateful that nations have standardized and created currencies for their people, so that I can travel and buy stuff without worrying about the reputability of a local bank when I go to exchange my money.
I read something recently about a Bitcoin based debit card system. How is that coming along? I don't know, but I want one! The Foundation would like one, too. We are trying to run the Foundation with only Bitcoins, so it would be nice to fuel up a debit card for some expenses.
Create an opt-in certification process for Bitcoin businesses. How will you be going about this? What will certification entail? TBD, But I am imagining that businesses could vet their processes and procedures against a set of published standards, pay for an audit, and then be able to help their users understand what level of security they provide, e.g. "Bronze certification -- the site could be trusted with 50 bitcoins of stored value per person."
Does the foundation intend to have control over bitcoin.org and thereby over the main distribution channel for Bitcoin-Qt? We're a member organization. Some of our members do have access to and influence over bitcoin.org and bitcoin-qt. I have no idea if they would like us to help manage bitcoin.org, since we just launched yesterday.
If the decision makers for bitcoin.org and bitcoin-qt want us to help out in those areas, I wouldn't mind. I don't think either of those things is super strategic to helping Bitcoin right now; there's more need for messaging and some financial security for the core team, and the other stuff we said we're going to work on this year. bitcoin.org and -qt publishing don't seem broken to me or risky right now.
Given that Mt Gox has a (rightfully deserved) place on he board, what steps can and will you be taking to ensure that independent exchanges are encouraged and not ignored? Also what steps, if any, can and will you take to ensure the public that the commercial interests of those on the board do not conflict with the decentralised ideals and paradigm of Bitcoin itself? I don't know how we'd encourage or ignore exchanges, since everyone is welcome to join.
I do think this individual / corporate angle is at the heart of the Bitcoin, though; it's got a lot of parties that care about it, passionately. Some are investing millions of dollars. Some are tirelessly advocating for Bitcoin. Many sit around and troll and waste people's time.
I guess that partly we expect our board members will act with integrity, and that if they aren't representing the needs of their member class, they'll get replaced with someone who will.
I also don't know how we would, practically, decentralize Bitcoin, even if we wished such a thing. I don't think anyone on the board thinks Bitcoin is doing badly. We're all really excited about it and want to help. I personally believe if corporations (a small group or just one) ever provably controlled Bitcoin, they would become vastly less appealing and useful. So, we're on watch.
Not as on watch as a paranoid bitcointalk forum troll wants us to be, but we're on watch.
Why do you require a real name and real address, when bitcoins core values are to be anonymous? The Foundation's core values include openness and transparency. I think the Bitcoin anonymous thing is overblown and a bit of a myth, by the way. Every bitcoin transaction links two addresses; often people can be determined from those addresses.
At any rate, we wish to make sure you can't stuff the ballot box during voting, and we wish civil productive discourse among our members, so we need real names and addresses.
If you just want to support us without joining, you can always send money to our vanity donation address: 1BTCorgHwCg6u2YSAWKgS17qUad6kHmtQW.
What is the current, largest obstacle when it comes to wider Bitcoin adoption? I think Bitcoin adoption is growing nicely. There seems to be a sort of stair-step function where people figure out something new and broadly appealing to do with them, and it makes a big jump. I expect we'll see that many times over the next five or ten years.
Doubts about the network's scalability, uncertain status about its legality or something else? Bitcoin's brand seems bad to me; mostly the highly publicized exchange attacks worry people. It's too hard to have a secure cold storage wallet for even a very smart individual. I'd like to see some of those things improved.
Does Bitcoin have any plan to combat criminals using the currency to purchase things on online black markets? I can't speak for Bitcoin, but the Foundation has no criminal combatant plans. We do want our members to use their real names and promise that they only engage in activities legal in their jurisdiction, though.
That's mostly just a way of us saying who we want to hang out with, and expressing some community values we think will help our organization be a success.
Did you expect for the Bitcoin concept to explode as it has? I sort of did, but I definitely didn't put my wallet behind that explosion. Sigh.
Also, where do you see it going in the future? I talk elsewhere in the AMA about what I'm hoping for Bitcoin.
Will the foundation be sponsoring Bitcoin software outside of Bitcoin.org? What do you mean? Like if Jeff Garzik made cool software that would help the Bitcoin world but didn't release it at bitcoin.org would we try and help him?
The answer is yes.
I.e., the Foundation would provide a service with recommendations such as wallet security for an exchange, but I don't think the Foundation should be in the business of "certifying". Yeah, there's an interesting set of questions there about certification. I would LOVE to see a certification that brought with it the ability to be insured against loss and theft. Think how nice it would be for an exchange or wallet business to be able to offer that insurance. That said, I don't know of any bitcoin company that has such insurance yet. I think we have some work to do vetting out the processes and procedures, and then some sales and relationship work with insurance companies first. At any rate, we won't be stumping up security for certified companies through the main Foundation corporate vehicle ever. But I think the membership will want to discuss what a good set of next steps is toward that goal, if we're all sold on trying to make it happen.
What's the advantage to using bitcoins over government issued currency, basically why should I invest my $US in bitcoins? Some people have ideological preferences for Bitcoins money issuance scheme.
Some are nerds, and like it for nerdy reasons.
Some just like being able to pay whom they choose when they choose.
Some deal with payment infrastructures that are scary (Paypal freezes are scary), or slow (wiring money in and out of small country central banks is REALLY slow).
Also, they're neat.
How does it feel to know that a kitten wearing a top hat has more upvotes than you? That kitten is so damn cute. I spent some of my AMA time going "AWWW"
How will you try to keep BIG businesses from buying their way into "THE" Bitcoin Foundation? Bitcoin is inherently free, it's peer to peer, it can be forked, it's not controlled by the Foundation, especially one that's one day old.
So, I look forward to large donations from BIG businesses. We will use that money to further the Foundation's mission. Our members will, no doubt, be highly engaged in discussions about what to do with large donations. I'm looking forward to it.
What is your opinion on Canada's new digital currency, "Mint Chip"? How does this affect Bitcoin? I don't know much about it, but I think it's cool from what I do know, (and is it technically flawed? I don't recall). I'm all for money system experimentation, as you might guess.
You are starting to get increased media/congressional notice. Are you at all worried about being shut down and prosecuted like E-Gold was? Who is we? The Foundation is a member organization, nothing else.
There are some bitcoin exchange operators that actively flout the same AML laws that got the E-Gold founders in trouble.
There are some that try hard to do the right thing, jurisdiction by jurisdiction.
Personally, I don't worry about the ones trying to comply, and I don't transact with the ones flouting the laws.
Why do you have different vote classes, is one class worth more then another? Corporate members vote their seats, Individual members vote theirs.
Anecdotally, there are fewer corporate members, so a corporate membership vote has a greater proportional influence over a board seat than an individual membership.
so a corporate membership vote has a greater proportional influence over a board seat than an individual membership. - So there may be poll when votes of both classes come together? Like asking ALL members to opt out changes to the source code? I would be stunned if we voted on source code, ever. I don't think anyone thinks that is in the remit of the Foundation.
Pragmatically, the dev team is one arm of bitcoin source code governance, and miners are the other, since they can refuse to work with code changes they don't like if they do it in bulk.
The board meets often, and should be listening to its constituents; sign up as a member, and then mail your appropriate rep. As a sample of what we discussed today: "Should we do an AMA? Who will get member signup confirmations out? Can we publicize Patrick's bylaws yet?" were the scintillating topics of conversation.
Will I be getting an e-mail with receipt for my payment confirming my membership subscription? Yes, we are ACTIVELY working on it. Apologies.
What's the dev's payroll? TBD, now that we know what our member signups are.
I don't know if we'll release payroll or budget numbers outside the membership -- something we have to discuss.
What power does this foundation have over Bitcoin? Why did you make Satoshi the founder without his permission? We have no power over Bitcoin whatsoever.
I think we felt a foundation that didn't somehow acknowledge Satoshi would be a bit churlish, like ignoring Linus completely while making the Linux Foundation. Satoshi is, as always, free to participate as he/she chooses.
Has there been a growth in algorithmic trading of Bitcoins in the past year? If so, is that growth in algos added stability to the Bitcoin Market? I have no idea. But I'm curious about this too!
Why hasn't (almost) anybody heard of you before today? I keep a low profile. Until yesterday. Also, I gave up on the forums a long time ago; not productive enough for me.
That was very informative, thanks. Not that hard to grasp when somebody spells it out. The reason you do it is to provide a second element of value to a chain of transactions; the first element of value is consensus -- what everyone else says happens.
Is there a reason for doing this? Or just a way to pace the grinding nature of mining bitcoins? The second, arguably more powerful one is provable computation time spent on creating the consensus. So you can look at a set of bitcoin transactions and say "Ah ha, that had roughly [say] $1mm worth of computation time put in to securing and validating it! I believe it's safe to consider my $55 transaction secure."
Just out of curiosity, do you have any idea how many people have applied so far? Yep. We'll release end of first-month member numbers in 29 days. :)
How does one go about buying bitcoins? Probably the fastest way is to ask a friend who has some.
Next would be to use a service like Link to bitinstant.com.
How long are terms for each board member? Two years.
Will the Bitcoin Foundation promote a Vulnerability Reward Program ? I would like to see that, but I think the first things to do in terms of importance are on our published list.
Will the funds for a permanent memberships be put into an endowment, or will they be spent immediately? We haven't discussed it. Budget discussions are next couple of weeks, now that we have our heads around some numbers.
We also have to discuss if the foundation wishes to go long bitcoin, or instead spend to its annual budget. All TBD; if you have opinions send them on to your member reps.
I'm curious about this too. I'm not sure I understand how they work entirely. Maybe somebody could Explain like i'm five... Totally. They are confusing; it's a truly novel solution. Essentially it mixes something non-intuitive and magical-seeming (public key cryptography) with something very hard to imagine a solution for (distributed timestamping among non-trusted parties).
We will be seeing the concept extended out into a number of technology arenas over the next 25 years I imagine. It's an incredibly powerful solution-space.
I spent maybe an hour on the wiki reading the FAQ and everything, and it still makes references to "blocks" and "mining blocks" and those that mine have the option of transaction fees.. and I'm still not really sure what is happening. Yep, like I said. I've been thinking hard about them for two years, I have a cryptography background, and I still have 'a-ha!' moments weekly, at the very least.
There are a couple pretty good bitcoin explanation videos out there, but I'm not up to date on what the best one is. Maybe someone helpful can post a link.
After establishing support for food and shelter for Gavin, will there be opportunities for other bitcoin developers to apply for grants - maybe for specific implementations or features desperately needed. I'd love it. I think Gavin will be working out the specifics of what we want to do. I'd LOVE to see money put into a huge test suite, personally.
Thank you for furthering the effort of Cryptocurrency, I have written several policy papers in this arena, and look forward to the day where the deep web stigma is removed from the currency. Thanks FapNowPayLater! We genuinely appreciate the support.
