I’m a longtime blockchain enthusiast and developer and one of my biggest gripes about this space is how quickly every new project is widely dismissed as a “scam” or “shitcoin” by so many people before it even gets off the ground. Sure, there is a lot of uncharted territory with pirates lurking to steal your bags left and right but with a small amount of personal education you can exist safely in the world of crypto I promise! With this article I aim to help lift your knowledge a little higher while helping keep your funds a little safer!

So What Is Happening?

On Tuesday February 18, 2020 a new coin named Ring (RNG) will be minted. This coin aims to bring two unique and fresh methods of proofing to the crypto game, quite literally: Agent-Based Hive Mining (borrowed from LCC) and Proof-of-Play Mining, where literal gameplay is used to hash and reward miners! To celebrate and help spread the word, the team is giving away claims of free RNG to all holders of the following coins:
  • Litecoin Cash (LCC)
  • Bitcoin (BTC)
  • Dash (DASH)
  • Dogecoin (DOGE)
It's being touted as the world's first crypto "4-way fork" but I'd really call it more of a "4-way claim" since its a brand new chain and not based on the code of any of the rewarded coins. It's simply a clever method of allowing a wider range of coin holders a chance to participate in the launch of these exciting new features!

How Will This Process Work?

On the 18th of February, a balance snapshot will be taken of the four chains listed above. Anyone holding a balance with any of these coins at the time of the snapshot will be forever eligible to claim their RNG at any time. Because the only way to prove ownership of a crypto address is to supply the private keys, and pretty much EVERYONE will tell you to guard those things with your life, below I will outline exactly what to do so there is absolutely 0% risk of losing a single satoshi! This method will apply to ANY claim rewards of any coin in the future as well. Always practice #SafeForking!

How Do I Safely Claim My RNG?

STEP 1 -- BEFORE THE SNAPSHOT -- VERIFY ACCESS TO YOUR PRIVATE KEYS
All core wallets will allow you to export a private key of any address in your wallet but many third party services like exchanges and hot wallets do not allow access to them. In these cases you will need to send your funds out of the third party service and into some kind of personal wallet where you can reach the private keys yourself. Then just wait for the snapshot to happen…
To make things easier on yourself, you can optionally collect your original coins into as few addresses as possible BEFORE the snapshot. Doing so reduces the number of keys you will need to empty and import later. It’s just less work!
\** SNAPSHOT HAPPENS HERE... ****
STEP 2 -- ATER THE SNAPSHOT -- EMPTY ALL ADDRESSES YOU WISH TO CLAIM
After the snapshot is confirmed, withdraw all coins OUT of each of your origin coin addresses into brand new addresses leaving the original ones quite empty. This way when you import later there is NO risk of losing anything! Also know that after you import these private keys you should never use them again for safety’s sake! It’s kind of the whole reason you’re even reading this article in the first place.
STEP 3 -- EXPORT PRIVATE KEYS FOR ALL ADDRESS YOU WISH TO CLAIM
This is the most difficult part, are you ready? Once each claim address is confirmed to be EMPTY, you must obtain each one’s private keys. This will entirely depend on the wallet you use (QT example below) but for all core wallets there is generally an option for exporting private keys somewhere in there. Collect them all!
How to Export QT Wallet Private Keys:⛔️ — DISABLE INTERNET FOR SAFETY — ⛔️- Open the QT wallet client- Click on HELP in the menu bar- Click on DEBUG WINDOW- Click on the CONSOLE tab- Click inside the input box at the bottom(if your wallet is locked…)- Type: walletpassphrase [Password] 600(this unlocks your wallet for 10 minutes)- Type: dumpprivkey [Address]- Copy the output hash, paste it into a list somewhere.(repeat as needed, clear your clipboard history after)- Type: walletlock (if applicable)⚡ — RE-ENABLE YOUR INTERNET —
STEP 4 -- IMPORT ALL PRIVATE KEYS INTO RNG CORE WALLET
\** PLEASE VERIFY THAT EVERY CLAIM ADDRESS IS EMPTY BEFORE CONTINUING... ****
The final step is to simply import each of these private keys into the new Ring Core Wallet to claim your free RNG rewards. The wallet handles this part automatically and you will see your new RNG balance right away. You can find this option under the File > Import Private Keys menu.
Importing a private key is the only way to prove ownership of a crypto address so this is unavoidable if you want to claim new coins from it. The steps above will allow you to prove ownership of your snapshotted address balance plus use its empty key to then claim your new coins thus keeping your original coins completely protected in the brand new address with a new private key (which you should now also keep VERY private!)
By emptying the address before you import it’s private key you eliminate the risk of theft entirely. One cannot take from an already empty jar. It should also be noted to NEVER use the imported address again as an added safety precaution*!*

How Much RNG Will I Receive?

Litecoin Cash holders will receive the highest claim ratio (5000 LCC = 1 RNG) as the LCC team are the ones responsible for creating Ring and wanted to extend a heart-felt thank you to the LCC community for their years of support. All other coins will be based on a 1:1 ratio with the value of Bitcoin at the time of the fork. This of course means 1 BTC = 1 RNG. For DASH and DOGE, however, their BTC market prices will determine their reward ratios. (For example if DASH is trading at 0.015 BTC each, then each DASH coin will net you a reward of 0.015 RNG to match.) Of course you don't need whole coins to claim, partial decimals work just fine!

What Value Will RNG Have?

That, my friends, is entirely up to the markets. No one in the history of crypto has had a perfect track record of price predictions so I'm not even going to try here. I will say, though, having gotten to play with their Testnet a bit so far that I am very impressed with the new Proof-of-Play method and how they have initially implemented it. It bodes very good things for the future of their project and this coin so I personally would expect its value to hold and most likely rise steadily as more people become aware of this groundbreaking new tech and it's potential to expand outward!

Is Litecoin Cash Still Going To Exist?

Absolutely! At least, from what I can gather. LCC has it's own purposes and will continue to be developed on. Ring is not meant to be a replacement or upgrade of any kind to Litecoin Cash. It is an entirely different proofing algorithm and a different mission statement altogether. It's more so meant to help expose the amazing new technologies developed on the LCC blockchain to a wider audience beyond simply its own fan base. If anything it'll act a sister chain that can help expose more folks to LCC in the future!

Disclaimer

While I am a moderator for the Litecoin Cash Discord server, I am writing this from an independent point of view as an educated crypto enthusiast with a passion for helping others navigate these waters. Having been an initial forker and third party developer on top of LCC myself, I feel I have some valuable insight into the direction the team is taking and I wanted to offer some sound advice for the upcoming Ring fork before the FUD gets caked on too thick.
I know a lot of people get scared easily in crypto because of the rampant scamming that goes on but I've watched this team work their asses off for two years to get out from under the stain of Charlie Lee's very biased, uneducated "its a scam" tweet which was endlessly parroted throughout the Litecoin community with nothing but blind party loyalty and no due diligence. The LCC folks are kind, wonderful hard-working people with big hearts and ambition and they have actually developed a unique proofing methodology that is likely going to impress a lot of people!
So before you go jumping on the "it's just another shitcoin" bandwagon please stop and take a real hard look at both Litecoin Cash (LCC) and Ring (RNG): two viable projects with something to bring to the table! If nothing else, hey, just claim your new coins and dump them off for some free money. You literally cannot lose if you PRACTICE SAFE FORKING!!!
Good luck, cryptonauts!

[ELI5] Extracting Privkeys from QT/Core

We have a constant stream of people coming back after abandoning Dogecoin and the sub in 2014 when the price fell. These people all have old versions of QT and are now basically trying to recover their coins, presumably to cash out and abandon us again. This is causing strain for the network, as far more people are trying to leech blocks than seed them.
The thing is, none of this is necessary. Especially if you're just going to dump coins. With resources such as https://coinb.in/#settings all you need are your private keys, and you can create, sign and broadcast transactions yourself. No client required, let alone one as resource-hungry as QT.

"So, how do I get my keys?"

First of all, lets talk about data management. The overwhelming majority of coins are not lost through theft, especially direct theft of wallets (as distinct from wholesale thefts/scams/implosions like Moolah, GAW, MtGox, Cryptsy, and even our own beloved Dogetipbot). Most coins are lost because people forget about their wallets and do silly things like reformat hard drives, lose passwords and so on.
So, everyone should have a wallet list. Here is a sample bit of HTML that gives you a page with two columns of wallets, one for local wallets you would withdraw coins to, the other the third-party wallets you would deposit coins to third parties through (do note that many services use temporary addresses generated for deposits which expire after 24h or so). A page like this is how I manage my 100+ wallets, and I have copies on my network and hidden online. Such a page makes it easy to at least keep track of all your wallets, for a trivial amount of work to set up.
 
 Sample - Twitter Fr DFXXz9gq3WkgJaHn9tXRChMhFQcwm4Y251 To DByYgzd4ec5Ku9vPag8XqoBfyRpsoj8Xs3 @TipDoge Sample - Backslash Fr DSDyv83VC1QtEnmJ4ATKFn5Sw3iC12VLmX To D9MsxSyJe5Mq7fWFRpC7zQQt1gexHccN4w Backslash To DJ3GL68kw8vh99RvxnEmQKE8A3cWRoEEqo Backslash Faucet Sample - Block.io To DE5QamzWVnxK2HmCS61cUsrn9iwgTArunU Block.io 

"OK, great, so now I have a list of my wallets. Now what?"

Now you're going to need the private keys for each of those wallets. Obviously you're not going to store these in a public place though. So you will need a separate file, which can just be plain text. Copy each of those addresses into it.
Now go ahead and fire up QT. If you haven't synced it in 3 years, its going to take forever, but that doesn't matter. You don't actually need the blockchain for this, so you don't have to wait for it to catch up.
Open up the console which is in the Help menu. Then give the command dumpprivkey with the wallet address you want the key to. Then use the up-arrow key to bring that command back, replace the address with the next one, and keep going until you have them all.
It will look something like this:
 13:05:18 Welcome to the Dogecoin RPC console. Use up and down arrows to navigate history, and Ctrl-L to clear screen. Type help for an overview of available commands. 13:11:06 dumpprivkey D9xDcRthB6XP4vRGqiyKdDfVJ7CWhYuBBi 13:11:06 6KEcssuq1wWUrFVmMF8yDxHuAdQMiRezz53zDxADLmyoXnix7iM 13:12:00 dumpprivkey DUDARNrGHVTFcCgriwRWgDQJPKDuDQr9jg 13:12:00 6JNk6NNFZcr49fbsD2jcTfTxFLjJKq9DHQ5JU8CYeZ2Cz6JdKMY 13:12:25 dumpprivkey DG6xnwCT6BXePaySqU85XocobZmhbJczQH 13:12:25 6JNXFv95Mp9SzehHw9jojjdxHRNPeh77qCsRbaNwJZMp9MKCAu3 
Yes, those are real wallets. But don't bother trying to steal my coins, I just generated them on https://walletgenerator.net/ and they're empty.
That's basically it. All you need to do is add some descriptions of what the wallets are, pretty up the format to your liking, and save copies in multiple, secure places, including printed out.

Remember, if you lose your keys, OR someone else sees them, you lose your coins!

If those were my real wallets above, you could use the keys and spend my coins. So obviously, don't let anyone else, especially annoying little brothers, get their grubby hands on them. But also make sure they can be discovered if anything happens to you. That's why the printed copies... nobody is going to go trolling through your porn or warez collection on the offchance there's something valuable in there. But they will look in your safe or wherever you store other important documents. Just be sure to leave a note as to what they are and how to use them. Remember the woman who came here a couple years ago who had found a USB stick with 110 BTC in a locked wallet.dat on it from her dead husband? I sometimes wonder if she ever got the money. Don't be her. Or him.

"OK, great. Now I have my keys. What now?"

Well, you can spend coins using https://coinb.in/#settings from any wallet you have the keys to. First step is to choose the network. Dogecoin (mainnet) obviously. Then go to Transaction in the +New menu. Enter your address and hit the Load button. It will pull in the first 100 transactions. Now enter the address to pay, and the amount.
Note the Transaction Fee box!
You want this amount to be zero. Depending on whether you're moving coins to another of your wallets to consolidate them (a very good idea.. go read the UTXO ELI5, which you will find a couple pages into https://www.reddit.com/dogecoin/comments/4yts6h/start_here_for_much_wallet_wow/ - Yes, I'm going to make you work for it, cos there's tons of useful stuff there you need to know), or paying someone else, you may want to select which inputs to use.
Once you're happy with the transaction, go ahead and submit it. You will now get a block of text, which is the raw, unsigned transaction. Copy this. Go to the Sign tab. Paste it. Add your private key and Submit to sign it.
After a little bit, you will get a signed transaction. Copy it. Go to the Broadcast tab, paste it and hit Submit.
That's it. It should go into the next block in a minute or two. Yes, even without paying a mining fee. Our network is so lightly loaded that there are no contention issues like the Bitcoin people have to put up with.

"That's it? So why do I need QT?"

You don't. The process above is all that's involved in spending coins. Everything else is window dressing. So there is no need to run QT, or any other client. Oh, and since you can download the site and run it locally (mostly offline), there is no security issue beyond the usual keyloggers/spyware that can compromise anything. And by knowing how to do this, you are much better protected from accidental loss than someone who blindly trusts black boxes they don't understand.
Oh, one final thing... if you really want to help the network by seeding rather than leeching, go ahead and run a full node. Instructions are in that link above. AND you may want to help seed the bootstrap file torrent from a couple of days ago. Just because YOU don't need it, doesn't mean others don't, right?

HD address generation seems to work in bitcoin 0.13.0rc1 :-)

"The only people who should be running fully synchronizing nodes are miners and businesses and uber-geeks like theymos who enjoy fiddling with technology."
Gavin Andresen
Compiled bitcoin-0.13.0rc1 from source on Ubuntu.
Like in older versions, there was no menu visible in bitcoin-qt (it was in the binaries) but I finally solved it through:
sudo apt-get remove appmenu-qt5
I then added the following code:
https://github.com/bitcoin/bitcoin/pull/8206/files
so I could dump the extended private master key (xprv....)
and recompiled.
To dump the wallet (that here includes the master key):
In bitcoin-qt: click help, then choose console
walletpassphrase passphrasehere 60
dumpwallet filename
I then checked some of the addresses generated in bitcoin-qt here:
https://github.com/bip32JP/bip32.github.io
Substituting the BIP32 Extended Key and using:
Custom Path: m/0'/0'/0' (for the first address, etc.)
THEY AGREED!
(edit: and also the private keys)
Thanks, core developers and especially:

It's nice not having to worry anymore if the backup of your (encrypted) wallet.dat file has become outdated.

Recovering unencrypted wallet from 2013

EDIT: I've been able to export my details from Bitcoin Core into a format I recognise, with addresses marked with dates corresponding to the last time I was doing transactions. Now to see which ones have any money in them!
Hi all,
So after seeing the price of Bitcoin I immediately thought back to my wallets. I backed them up years ago. But they will not import into any modern wallet software (some just hard crash.) The software I last used with these wallets was Bitcoin QT.
I was able to extract a .json file from this backed up wallet.dat using pywallet, but I have no idea what to do with the resulting data. I read about Electrum having a "Sweep private keys" function, and about using Bitcoin QT to dump private key information. But since no receive addresses are showing up in these old versions, I have no idea what to dump. I tried my best at importing the private keys from this data after matching one private key to some Bitcoin QT output, and put all my private keys into the sweep. However, it says nothing was found and my balance remains at nothing.
I cannot find what my old BTC address was, so I'm unable to check if the funds are still there in the wallet.
Is anyone able to give me some steps on how to get this loaded into a modern wallet? Nothing I've tried so far works.

need help recovering my wallet.

So i bought some coins thru coinpal in 2011. I have the email which contains the bitcoin address that the coins were sent to, at some point in 2012 or something, i lost interest in bitcoin. reformatted and repurposed the drives, etc. but i did backup my wallet files, and after searching i found a wallet.dat file that is compatible with the old bitcoin qt client
under the recieve tab, it shows 3 addresses, one of which has no label, The second has the address contained in the email from coinbase, and the third has another address that i believe i had sent coins to at some point.
The two "labels" i can search on blockchain.info and they both have a balance. HOWEVER.. when you right click copy address, it copes an entirely different address.
this address has a zero balance. in all 3 spots.
So ive tried importing the wallet into bitcoin core, it does not show anything, so i know this is an older file created by the older bitcoin qt client.
ive run several commands in the debug console, trying to dump the private keys, but for some reason the wallet file i have does not contain the private keys for the two addresses that have coins.
I had someone trying to help me but he says the wallet is encrypted.
so i opened the debug console and tried to unlock the wallet using the passphrase i think i would have used, and it tells me that the wallet is not encrypted
which makes sense because i remember specifically not encrypting the wallet because i always forget passwords.
Whats weird is, how did these addresses get put into the label section of the recieveing tab? i know for a fact that one of them which contains 2btc i could have manually entered myself, because i do have a record of the address on my email from coinpal.
the second one tho, i have no idea where i would have found the address. They both have one transaction right around the same time, and they both have a balance. one of 2btc, one of .4 btc. the transaction dates line up to when i bought the coins.
im having data recovery done on my hard drives at this point to look for more bitcoin wallets, because im pretty sure i had more bitcoins in there as well. at least 6 or 8 more that i can remember.
So is it possible that the wallet file is corrupt? if so is it repairable?
or is it more liekely that ADDRESSES listed in the recieve tab are the actual addresses contained in the wallet file, and the labels are something else? im ripping my hair out trying to figure this out.. I have a wallet file. it has 2 addresses listed which i can verify both have a balance, but i cannot gain access.
i remember in 2011 buying some coins, and like the next day my computer crashed and got stuck in a boot loop so i had to reformat. and i remember backing up my wallet on a flash drive, and trying to restore it and the coins not showing up even after the blockchain loaded.
i have not yet finished loading the blockchain on my bitcoin qt app, so maybe that has somethign to do with it, but i find it odd that these addresses do not have the correct private keys.
any ideas?

Recovering vertcoin-qt wallet from 2014 backup?

So every couple months I try for a few hours to recover this vertcoin wallet backup from early 2014 and end up giving up and playing overwatch. It's an exported wallet backup with some coins I mined during launch and from when I was diversifying my bitcoin around the same time.
My problem is when I try to replace the .wallet file in the vtc data folder I get the following error "A fatal error occurred. Bitcoin can no longer continue safely and will quit."
I've dumped the wallet with pywallet and it definitely still has a balance. There's no password that I know of on it, but if there is I'm pretty sure I know what it is. I just can't find a way to open it with the qt client or to dump the private keys directly from the file, and I don't know what else to do. I've researched all I can, and any searches I seem to run now just lead back to stuff I've already read.
It's been awhile since I've been involved with crypto so I figure you wonderful folks are my best bet. I won't be sending anyone my wallet file, but if anyone can help me towards getting my coin off of it I'd be happy to reward you, and I have a feeling this would be a good resource going forward for people with the same issue. Especially since it's probably something dumb.

How do I turn my wallet.dat file into something I can actually use?

So here's my situation: I have a wallet.dat file that contains my Bitcoin and I have it backed up well and wrote the password down.
So here I am, thinking I did everything correctly and I could just sit on it without having to carry out any maintenance, but then I look today and realize the blockchain is now 96 gigabyte big and still exponentially growing.
So, I can't maintain a full node anymore, I'm about 60 gigabyte behind probably. No problem, I have my wallet.dat file.
But here it comes: Lightweight clients refuse to work with the wallet.dat file. All I see everywhere are people telling me to do geeky commandline shit. If it involves github, I'm out. The alternative I'm given is to export my private keys to blockchain, which seems like the dumbest thing possible and not secure at all. I'm also told to simply send my Bitcoin through Bitcoin-qt to a new wallet. The thing of course is, that would require me to first synchronize my Bitcoin-qt client, which will take an eternity.
So, the suggestions I see are to use Pywallet from Github to dump my private keys into an unprotected json file on my computer. Who could possibly think of that as genuinely safe or user-friendly?
Why is it so hard for you guys to make a lightweight bitcoin client that can open my wallet.dat file?

How to dump private keys from corupted un-encrypted wallet.dat with btc on it ?

I received bitcoins to one adress on my wallet, but Bitcoin-QT didn't synchronized till the end beause I didn't had enough space on hard drive. I backed up wallet and whole /.bitcoin folder. Newly synchonized Bitcoin-Qt could not open that wallet and it says it's corrupted. Blockchain couldn't open it and pywallet couldn't dump keys.
How can I recover it ? If I am using pywallet to recover it, what exactly should I type ( I have Ubuntu ) and how can I choose that pywallet doesn't try to recover wallet from whole partition but from chosen file ?
If I open wallet.dat with hex editor can I find there private keys and how to recognize them ? Are there some other ways to dump keys ?
Thx

Rescuing my old bitcoin-qt wallet?

I haven't used bitcoin for a while, and haven't got a brilliant understanding of it. I've got my.wallet file from a backup and would like to move it over to multibit hd (open to other suggestions).
Question is, do I have to wait days for bitcoin-qt to synchronise before I can access it? Googling suggests that I need to use the cli to dump my private keys, but I'm getting 'no block source available' when I try to open the wallet. I'm hoping that this is because it's not synced with the network rather than anything more disastrous?!

State of the Redd-Nation :: May 23, 2016

Reddcoin Weekly Development Update

Welcome again Reddheads to another weekly update of Reddcoin Development.
This past week has achieved quite a few updates.

New v2.0 Wallet and testing progress

During this last week, I have been performing testing on the switch-over logic from v3 to v4 blocks on testnet using both the version 1.4.1 wallet and version 2.0.0.0 wallet. Results have been better than expected and I am very happy with the progress so far.

Network Testing with Super-Majority

The recent testing with testnet was performed by setting the super-majority to 510/1000 blocks (51%). That is, when there have been 510 v4 blocks created in the last 1000 blocks, the rules for v4 blocks are enabled (Enforce DER Signatures). v3 blocks will then be rejected by the network.
On mainnet, the setting will be updated to be a Super-Majority 85%

Staking with different versions

Wallet Staking Block Ver Accepted by v1.4.1 Accepted by v2.0.0 Rejected by v2.0.0
Ver 1.4.1 YES v3 YES NO YES
Ver 2.0.0 YES v4 YES YES NO
SOME NOTES: After the switch of Super-Majority completes, version 1.4.1 nodes will continue to stake however, the network will reject those blocks. This is expected behaviour.

Transferring between versions

v1.4.1 v2.0.0
v1.4.1 YES YES
v2.0.0 YES YES
SOME NOTES Current testing of transferring coins between different wallet versions has been successful. Current indications are that if you are not staking, you will be able to continue to use v1.4.1 wallets. More testing to be done.
If you have any questions, or would like to know more on this, please let me know.

Translations

Translations continue to be updated which is great to see. Thank you to all those who are contributing their time and effort.
@Serkan34 continues to dominate on the European languages.
This is the running list of desired languages, and if you like you can also check the overall running list on transiflex here.

Wallet Recovery

As mentioned last week, wallet recover is no easy task. There are a few tools around on the net that can help, but it is no way guaranteed to provide 100% recovery.
So, it is important that you get in the habit of routinely backing up your wallet.dat file
For the second time in as many weeks, I have used the utility called pywallet that in my case has done a reasonable job to recover broken wallets. It is a python based tool that allows some low level manipulation of wallet files.
In this second case, it involved recovering the private keys from a testnet wallet (100K keys in total). The wallet.dat would load into Reddcoin-Qt, but then the application would sit spinning its wheels, without error, and no way to dump. Running the QT application with -salvage wallet would truncate the number of addresses that should have been available ion the wallet.
So, using the pywallet, I was able to load up read the available privatekeys in the wallet and dump the keys to a text file. This essentially was the same as last week. 100% of the privkeys were salvageable
I still have some problems importing those directly into a new wallet using the pywallet tool, and with such a large number of private keys, manual input was not an option.
I wrote a little script to pull the private keys from a text file and send a importprivatekey RPC command to the wallet. A little slower, but none the less it was effective and successful.
After starting the wallet with -rescan, it brought everything upto date with those associated addresses and their tx's into the wallet.

Large number of Micro Transactions on mainnet

Over the course of several weeks, there have been a number of instances where a large number of small transactions were broadcast onto the network.
It was brought up in a couple of forum messages on reddit and reddcointalk, so I thought it might be worthwhile just to touch on it again here.
Firstly, I would like to say, this is similar to reports that occurred on Bitcoin network where small transactions were sent to fill blocks. So I was interested to monitor just how such behaviours would occur on Reddcoins Mainnet and what the effects might be.
Reddcoin mainnet has in effect a 10x larger capacity that Bitcoin. The blocksize for Reddcoin is 1M, and the block generation time is targeted every minute (Bitcoin is 1M blocks every 10 minutes).
In the 'worst' case the maximum capacity that these transactions took on the network, was to occupy less than 25% of each block (about 230K in total)
With the number of transactions that were occurring, there were at times excesses of transactions that spilled over into subsequent blocks (again, only filling each of those to 25% capacity). When this occurred,e there were runs of up to 10-12 blocks that were filled.
In the current state of the network, where volume of transactions generally is low, it has been a good exercise to monitor the behaviour of sudden peak demand. I didnt hear of nay cases where normal transactions or staking were affected.
Thats is not to say, we are immune, If the normal operating capacity of a block was 50% or more, this would be more a concern and there could be an impact to the time of confirmation of a transaction.
Suffice to say, the current side effect is, a number of you may have a lot of small transactions sitting in your addresses. I would not be too concerned at this point, and would suggest to let the PoSV staking take care of those in due course (it will take a while to get selected due to the size), or in your next transfer, manually select a few to send them on their way.

Performance of PoSV

One of the things that has interested me for a long time with Reddcoin is how the POS mechanism behaves over time.
PoSV is unique amongst the POS crypto-currencies in the way that the weighting mechanism works, and in the way the stake reward is weighted depending on how long the coins have had to age.
A lot of things can influence the amount for each of your stake rewards,
Working with @deadpool, and @reddibrek, they have been trying to define it is simple to understand terms
But I am also studying the network in much greater detail in relation to a post on the ReddcoinTalk forum regarding PoSV v2.
This was the original statement made about 1 year ago, and I believe there is merit in re-visiting this PoSV v2 proposal. It provides and extra incentive to everyone who continues to stake, and in doing so get a bigger percentage of return.
So in my spare time I have been extracting information about the current network, the blockchain and the metrics of how it is functioning, what returns stakers currently get and whether this remains a viable option.

Getting involved

We are a global community, and cross many borders but boundaries do not need to hinder us.
The crypto currency world has not reached its tipping point yet, but when it does, it is sure to escalate at an amazing rate. There are going to be many ups and downs, and an interesting ride for sure.
If you would like to get involved and dont know where to start, reach out and we will see where you can jump in @Deadpool has a great Trello site going with activities that need looking at.

In Closing

There is still plenty to do, but we are getting closer and I look forward to another productive week.
So where ever you are, enjoy your week ahead
Keep on staking!

The ultimate back-up plan: Your private key, stored in the block chain, encrypted

[edit: It is the ultimate back-up, but it doesn't mean it is the safest. I'm too tired to figure that out. I'm just explaining how to store a private key in the block chain, in case it is useful or can be made useful.]
I had that idea if someone is interested, though I guess people won't like it. It's a bit wild. We encrypt the key and put it in the block chain with a trick.
I'm not saying everyone should do this, but it could be useful to know it can be done.
If you trust encryption and your password more than back-ups or a third-party, then it could be nice. I'm no encryption expert but it should be strong enough.
"Instead of taking 1.3 quadrillion years, our magical cracking supercomputer would only need 328 trillion years." http://www.kotfu.net/2011/08/what-does-it-take-to-hack-aes/
If it's flawed or gets cracked after a billion years, I decline all responsibility. But you can be sneaky about it. I propose a sneaky trick at the end. It's a bit rough on the edges and crazy but I'll put it out there. If people like it, there are always ways to streamline.
Anyway, you can't memorize the key as you can memorize a password. It's true you can put it on paper; then lose the paper. You can encrypt it and keep it on hard drive, then lose the hard drive. Or on a service, and lose the service. The block chain though, is going to stay around as long as you need the key. So I suggest this whole alternative.
You can still put the information on paper if you want. But now, just your memory is enough. Just the password.
The drawback is the infinitesimal odd of someone finding out and spending a lot of years and resources on brute-forcing. I'm not sure what would be the odds of success. Just make it so decades of computing resource cost more than what's inside.
Now I'll explain how to do it from A to Z, for the few interested.
Plan: 0) Vanity 1) Get the key 2) Encrypt the key 3) Put the key in the block chain 4) Retrieval 5) Conclusion
0) Optional: Vanity I recommend a vanity address (choosing the first part of the address). So if worst comes to worst, you find it from memory in the block chain. And also, it's kinda neato. How-to: first, download VanityGen, direct/wiki. Extract it, then Open a console window at the location with shift-right click in the folder, if you have vista/7/8. Then type "vanitygen 1something" in it. It has to start with 1. If it's too long it'll take a lot of time. Ctrl-C to cancel if it's too long. Faster with GPU: oclvanitygen -D 0:0 1something (maybe broken atm) When you have the key, type "importprivkey mykey" in Help->Debug->Console of bitcoin-qt, to add it. Result of this optional step: A beautiful address which can be retrieved from memory if needed (after it has been seen in the block chain with a transaction)
1) Get the key - Download open source Pywallet: direct/profile - Extract pywallet.py somewhere. Shift-right click in the folder and "open a console window" - In the console, type: pywallet --dumpwallet dump.txt If your wallet is encrypted, then add --passphrase=PASSPHRASE Now you find the key in dump.txt. (note: it reads the wallet at C:\Users\x\Bitcoin) Result of this step: the private key; it looks like 51 characters starting with the number 5. (To delete dump.txt, you can use a software so it can't be recovered from HDD, like Recuva it seems)
2) Encrypt the key - Choose an algorithm. Personally, I pick AES-256. - Download a trustworthy program to encrypt text with the algorithm. Here are two with GUI I found. It's open source but I didn't check it, so it's not 100% safe: http://sourceforge.net/projects/textcrypt/ https://code.google.com/p/immediatecrypt/downloads/list They're both jar files. Maybe you can click them. Personally I have to go in the console; I'm so tired of that coffee cup. "C:\Program Files (x86)\Java\jre7\bin\java.exe" -jar ImmediateCrypt.jar. It gave me an error though. Not the other. Maybe someone can suggest better. - Choose a good password. It's all about the password (and the software). AES is weak with weak password. And crazy strong with a good password. This is not like websites with protection against brute-force. People can brute-force fully if they find out. I like psycho-pass method which is about a pattern on the keyboard instead of semantics. Side Info: http://www.jmir.org/2012/1/e10/ http://www.jmir.org/2013/8/e161/ Or a passphrase if you want. Here is a nice table with password entropy: http://en.wikipedia.org/wiki/Password_strength#Random_passwords Below 64 bits of entropy, it's too unsafe, it's too weak. We need 128 bits or above, as far as I know. That is 25 random alphanumeric. If you're feeling paranoid, 256 bits. You can check entropy of password roughly here: http://rumkin.com/tools/password/passchk.php Remember it is not like websites. There is no "Forgot password?" button. Memorize it permanently; and maybe write it down in your favorite book just in case, I don't know. Result of this step: the encrypted key. It doesn't matter what it looks like as long as it takes you back to the key when you click "Decrypt". (on a different software, preferably)
3) Put the key in the block chain It works by sending some minimum amount to fake addresses, with data encoded in the addresses. Can't try this part because I don't have bitcoins. :[ Only a wallet! If some liked the guide particularly: 1thxd4KJLhBMcfCYaVKYMA8Atv3Dfx9hb :3 I'll follow the method of this great article: http://www.righto.com/2014/02/ascii-bernanke-wikileaks-photographs.html (the blog is remarkable!) - We're supposed to split the encrypted key in chunks of 20 characters. Then convert from ASCII to hex. Last chunk we fill with extra zeros. I wrote a little javascript to do it all automatically! If you don't like it, find a software, or do it manually. Not tested much but seems to work for my test. I'll say how to know if it worked. Copy that: encrypted='';har=(encrypted.split ('').map(function(c){return c.charCodeAt(0).toString(16); }));ek="";har.forEach(function(c){ek+=c;});while(ek.length%40!=0)ek+='0';iEK=0;ek2='';while(ek.length>0){ek2+=ek.substr(iEK,iEK+40) + "\n";if(ek.length>=40)ek=ek.substr(40,ek.length-40);else ek='';};ek2;
Check eventual comments to know if it's a hack/broken mess.
I don't do much Javascript, or much anything. Paste the whole thing in the javascript console. To open the console: Chrome, Ctrl-Shift-J. Firefox, Ctrl-Shift-K. IE9, F12. Put your encrypted key between the '' right at the beginning, then enter.
This should display rows of 40-characters chunks of the encrypted key in hex format (numbers, and a to f). I have 6 chunks but it depends on encryption. It should give twice as much characters as the input except for last zeros, and follow this conversion table from Char to Hx column. If it doesn't, call the police. Or use some Ascii to Hex service.
Now we take these chunks one by one and use https://blockchain.info/q/hashtoaddress/the_hex_chunk to convert to BTC addresses.
Send spare money to each one (the strict minimum is suspect and it'd get found easily) in the right order (wait for 1 or 2 confirmations each time to be sure).
And we're done! The information is safe and cozy, in the block chain. Not safe from brute-forcing, but safe from ourselves; and that's safer, isn't it?
4) Retrieval
Alright, how do we go back from the addresses to the encrypted key? I can't try it myself, but apparently, according to the article: 1) Get the transaction ID on blockchain.info, by going to the wallet's profile 2) Go to http://blockexplorer.com/rawtx/your_transaction_id 3) There will be something like that: "out":[ { "value":"25.08603421", "scriptPubKey":"OP_DUP OP_HASH160 27a1f12771de5cc3b73941664b2537c15316be43 OP_EQUALVERIFY OP_CHECKSIG" } ]
And you need to translate the "27a1f12771de5cc3b73941664b2537c15316be43" part from hex to Unicode. The result should be the chunk of encrypted key, written in hex again. You put all the parts together in order, remove extra zeros. Then use a program to go back from hex bytes to ASCII. Maybe someone can do it or I'll put the javascript one of these days if people are interested; I don't think they'll be. Usually I'm serious and extensive but you can't imagine how tired I am these days, of everything. Anyway, you put that ASCII in the AES program with your password, you click Decrypt.
Then you have your private key.
If you do this, don't lose other back-ups until you have successfully retrieved the key, to know it works.
5) Conclusion I understand that there's a small chance that someone figures the transactions are data, reassembles the parts, has massive luck and breaks the crazy strong encryption with supercomputers and botnets in less than decades, or aliens hack your bitcoins with quantum computers, ect... But I don't know, that seems very unlikely to me; more unlikely than losing personal back-ups or third-parties being untrustworthy.
More importantly, it gives peace of mind of not having to manage back-up stuff. You can format your hard drive and burn your house down if you want without worrying about losing stuff; well, except the house. And maybe the wife. Or you go to prison 20 years, and it'll still be there. If some of you want to go to prison. I know of one.
Here's a complicated idea for the extra-extra-paranoid: You send just one letter by one letter of the encrypted key, into dozens of fake addresses, to which you send bitcoins you got from an exchange and not from the main wallet, and only you know the correct addresses/order with the data, because of a pattern in the other letters. For example, the 2nd letter of the 1st data part is the 1st letter of your password when it's hashed. The 3rd letter of the 2nd data part is the 2nd letter of your hashed password. Ect... And it's not true for the other parts. So you know the order, but not someone without the password. It can go like this for many parts, then maybe if you run out of letters you send through a different wallet. All other characters are misleading except the 1st one, or last one, being the key character. And you also send money to other fake wallets which are purely misleading. Even if a flaw in AES was found and it could be broken instantly, an attacker would have to find the correct combination even before the strong encryption brute-forcing, he can't even know if he has the right combination, and that can be a big number of combinations. You can do the math. It's exponential stuff, I think. That's something I just thought of quickly, and I don't know much about any of that. Someone can find better. (Maybe, or maybe not, there's something about the encryption output which makes it so we can find the order back without password, then we'd need some kind of trick to obfuscate the position or nature of key characters but I won't spend any more time on something likely to be wrong/uninteresting).
tl;dr: "It works by sending some minimum amount to fake addresses, with data encoded in the addresses. "
Point is, once we know we can store data in the block chain, there are plenty of ways to make it so we're never locked out from the main address.
Well, if you can remember the password.
I hope this was useful to someone!
Goodbye

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.
