"Test 1A" means: testing this privkeys: 5HpHag165TZAG1PH3CSu63k8Dbp*D8s5ip*nEB3kEsreAnc*uDf
there are 58*58 (=3364) so groups, with your cpu (~2 sec/testgroup) you get the result about 2 hours. Thanks. I edited my post the same time you posted this. You say 58 where I assumed 62. I didn't realize until now the private key excludes the same characters that are excluded from the address. i dont know vanitygen, how do you run it to test this keys?
Vanitygen searches random private keys until it finds an address with a certain prefix. Example: 1Loyce. Annoyingly, it segfaults since I've (re)installed libssl-dev. In the meantime if you find another copy of your private key, or manage to remember what the values were, just let me know so I don't waste time on it.

Block size certainly affects miners greatly. An entire block needs to be relayed across all nodes in a timely manner for mining to be decentralized. The more data propagated, the more latency.
That's the same for all miners. Even if they spend a few seconds downloading the block, and all miners lose a few seconds from the 600 seconds average between blocks, the difficulty will correct for this. One way or another, there will be one block every 10 minutes. I think Mike Hearn, who blames the Chinese “Great Firewall” censorship system for limiting the Chinese miners, could be right. They have the advantage of very cheap (and dirty) electricity, but they don't have decent internet. And since the hash rate puts them in power, they can stop blocks from growing to protect their interests. There could be any number of reasons why blocks aren't filling up (or why average block size spiked earlier in the year). There may have been ongoing DOS/spam attacks that have died down. Services (and people) have probably gotten smarter about batching payments and cutting out unnecessary spends (I have). One would think that rationally, miners would be picking up transactions with low (but non-zero) fees instead of mining non-full blocks... so it may be a matter of fee policy enforcement, as we do see a steady ~2000 unconfirmed transactions even after many 100-600kb blocks in a row.
Mike Hears says this: The reason the true limit seems to be 700 kilobytes instead of the theoretical 1000 is that sometimes miners produce blocks smaller than allowed and even empty blocks, despite that there are lots of transactions waiting to confirm It could very well be the miners simply don't care about the transaction fees! They get 12.5 BTC, and if they spend a few seconds on processing waiting transactions, they risk losing the block to someone else. So they skip the transactions and claim the 12.5 BTC as fast as they can. If this is the case, the block reward does the opposite of what it should do: enable transactions! It may need several more halvings for this behaviour to change. |

Compile this code: http://pastebin.com/S8WARrRnThis code is for address with 5 unknow "-" chars!! First set your address to 58. line, and compile the code (you need openssl dev installed, apt-get install libssl-dev): gcc -o recovery recovery.c -I /usr/include -Wall -lssl -lcrypto -O2 run it ( ./recovery ), and stop with ctrl+c, you got 5 "index: XX" lines. Modify the "define C_X_INDEX" lines in the code (line 49-53). Compile again. Run again and wait, get a coffee, or 10.  I've got it running, to test  Test: 11...1.984325s

5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf I'm curious: how did you do this? 5 digits isn't that much, so an altered version of vanitygen could brute force it in seconds. But do you just happen to have that lying around? |

Google brought me to this old topic. I was looking for a method to import a vanity address into a paper wallet printed by bitaddress.org (but I didn't find what I was looking for). I'd like to combine two posts into one new post: 1. Go on bitaddress.org offline, on a Ubuntu live USB
11. Print out the wallet details page (to have the QR codes)
This gives you a simple (but ugly) printed page. I wouldn't say "buy", as the site doesn't sell paper wallets (they do sell related items though). Bitcoinpaperwallet.com is the easiest site I've found to print a vanity address into a paper wallet that looks nice. Bitaddress.org can print good looking (small) paper wallets, but it doesn't give the option to import a private key. Bitcoinpaperwallet.com makes this possible. The paper wallets are quite large though. Bitaddress.org produces this (no vanity, fold into 3 layers, then use tape or laminate it):  Bitcoinpaperwallet.com produces this (vanity possible, fold the right side into 3 layers):  Not only does it look better than just printing the overview-page from bitaddress, it's also not possible to copy the private key for anybody who sees the paper without leaving evidence. |

I don't think you understand what I said. The demand should outweigh capacity if fees are to rise. And fees must rise significantly if the chain is to remain secure many years from now. And regarding capacity....firstly, Segwit, Schnorr and other optimizations + LN will drastically increase capacity. Secondly, it's not clear that fees are discouraging adoption at all---data, please? For those that view BTC as digital gold, 10 or 20 cent fees are not discouraging at all. Miners earn about $7000 every 10 minutes now. A few months ago it was $12000. It was never a given that mining should earn this much. I know that eventually all revenue has to come from transaction fees, but to do that now would mean either having 25 times higher fees, or 25 times more transactions (and more users) at the same fees. Or a 25 times higher value, or somewhere in the middle a bit of everything. Bitcoin was also secure when miners were earning much less dollars per block. For as far as fees discouraging adoption: I don't have data from that. But it's easy to see that blocks are full, and full blocks simply mean it's not possible to do more transactions. |

I don't like topics about block size. It's smarter to talk about free space within each block. On an average computer, most people would say you need to keep at least 15% free space on your hard disk so that you work on files without hiccup. It's the same thing with BTC. If we're close to max capacity, things will be less smooth. It may even stall at some point and we don't want to see that.
In most blocks, less than 0.2% free space is left. I completely agree, and I've been saying it for a while: this limits Bitcoin growth. It also limits how many people can use Bitcoin, as any new user takes away a transaction that an existing user can no longer make. Lightning Networks may work in the future, but we need a solution now. And with "now" I mean about a year ago. And people worrying about bitcoin getting more centralized if we get bigger blocks are not considering the fact that we have been sitting on 1MB for years now, and since that time internet has gotten cheaper and disk space has gotten cheaper as well. So we can easily increase the block size and we can do so again when we need to (and by that time, internet and disk space have become cheaper again).
Miners spend millions on hashrates, and barely anything on disk space. By changing that ratio a small fraction, all miners can afford enough disk space for much bigger blocks. The problem is that miners now only have a financial short term incentive to increase their hash rates, while they have no direct gain from larger blocks. If we perpetually increase capacity ahead of demand, fees will never rise. Transactions will always be free or nearly free for users. This will not end well in a future where block subsidy ends and fees alone must support the security of the network (by incentivizing miners). If we did this, we are basically depending on mass adoption and skyrocketing price being guaranteed. That's probably not a good engineering decision.
The demand is there already. By not increasing capacity, mass adoption becomes impossible. It's already not possible for just 1 million people to make a few transactions per day, let alone much more people. |

Despite my edit, I got the wallet.dat file by PM (through a very unsecure medium).
Basically I can't add anything we didn't know yet: it shows 4 empty Receiving Addresses, and can show the private keys for them. It shows 1 Recent transaction (6/11/16 09:46 0.00000 mBTC), as one of the screenshots above shows too.
After --salvagewallet (which took over an hour), that transaction is no longer shown. The wallet file gets 30 kB bigger though.
Before --salvagewallet:
pywallet.py --dumpwallet:
Wallet data not recognized: (many times)
Then 4 lines showing the 4 empty receiving addresses that Bitcoin Core shows too:
Wallet data not recognized: {'__type__': 'purpose', '__value__': '\x07receive', '__key__': '\x07purpose!1RKsJ21eFDDron59XvuUshQjnMbpf3Ysr'}
After --salvagewallet:
pywallet.py --dumpwallet:
Wallet data not recognized: {'__type__': 'keymeta', '__value__':
I would have loved to give good news, but now I'm out of ideas. Time to sleep here, suggestions what else to try tomorrow are welcome.

When the generation process is complete, click Paper Wallet on the top.
6. Now here's a tip I can give you: split your money into more addresses. So if you got .1BTC, split it into 4x .025, 2x .05, 10x .01 or anyhow you want. This is a step to make it even safer in case you are afraid of one of them being hacked or stolen. The problem here is: it is as safe as you can keep your paper! It's like cash: how safe would you feel if you keep $1000 in your house? And what if you want to keep it there for 10 years? What if someone just steals it? 7. You may be now wondering what "BIP38 Encrypt?" is. This is a Wallet Encryption, so you can't take the funds off you wallet without entering the password. It's good for the safety in case your house will ever take part of a burglary, but it's harder to find wallets accepting these encryption (when you need to import it) and if you forgot the password.. It's all gone. This stops the problem from someone stealing your wallet and taking your money. But if the wallet is stolen, you can't access it anymore either. So you need backups. On top of that, for long term storage, you need to remember the password. You can't use a password that you've used anywhere else, so it's less likely you can remember it for a long time. Or, if bad things happen to you, someone else in your family can't access it. I'm still wondering myself what's a good way for long-term offline storage. In the end it's a compromise between getting-it-stolen and losing-access-on-your-own. 8. When you're done, press "Print", print the paper and cut it (so you'll have 'banknotes'). Now I recommend you to laminate the paper you're going to print after you cut it, to make it waterproof. Here's how I did it, REALLY cheap: look up "DIY Scotch Paper Laminating" on YT. It's less than $1. Shut down your computer, unplug the USB/eject the CD. With any laserprinter, the paper will last hundreds of years. And a tip: always withdraw ALL your funds from a paper wallet. So if you have a 0.1BTC paper wallet, don't take just 0.001 out of it. Take everything, for safety reasons.
Note: not using everything means the change will be send somewhere, depending on what software you use. That's another reason to swipe the full balance. |

The wallet where the payment was recieved disappeared from BitCore together with the bitcoins. Did you send it to another address within your bitcoin core wallet? Everything tasted of the tips above - did not help
Who dig deeper wallet.dat file? send someone?
We are pleased to share 50/50 with the successful return of BTC
Feel free to send it to me, if you trust me with this. I like a challenge and have a full blockchain downloaded on my PC.I'll PM my email. I realize just suggesting this can get me red trust. I posted it in public hoping that would give me credibility, but I don't want to risk red trust. Hence the strike-through. |
