1  Economy / Digital goods / Are old addresses worth anything? on: December 04, 2020, 09:05:32 AM
I've got a ton of Bitcoin "firstbits" addresses that were generated (and written to the blockchain via transactions) back in the day... 2011-ish.  Is there any interest in those?  Thought there might be some interest as a sort of novelty to have, a digital collectible.

They've been kept on air-gapped storage, never seen network or internet access, and would remain that way (securely deleted as sold).  I generated them and have been the sole owner of them this whole time - no one else has touched them.

Some random examples include:
1MunCh - 1MunCh1kFAwisrTySvZvyxsXkrEeFCMehH
1BLing - 1BLingJstkxW53nsjNbDe7zFUJ5P42KuJC
1DiRty - 1DiRty8t4qJhCmp5QL2BqThdHLcAgHTDeb

5  Bitcoin / Project Development / [BOUNTY] Fully functional open source code for Firstbits website on: September 02, 2014, 11:05:19 PM

I cannot count the number of times that firstbits would have been useful to me personally, and I imagine to many others as well, so I would like to get serious about revitalizing the firstbits website.  I'd like it to be open source as well, so anyone can help improve the code or host a copy down the road.

The code should replicate the behavior as listed here:

Basic logic should be as follows:
1) Gather all Bitcoin addresses from a block.
2) Compare first two characters of first address in the block to firstbits table.
3) If a match is found in the table, add another character of the address and repeat.
4) Once it is not found, add temporary firstbits into an array and move on to the next address.
5) At the end of the block, compare all temporary firstbits found from addresses in the block to each other.  Resolve any conflicts by adding characters to conflicting addresses.
6) Add completed list of firstbits to firstbits table.

Other requirements:
- Must store data in a MySQL database
- Must use either PHP or python (or both)
- Must be able to connect to a bitcoin daemon (bitcoinQT) to gather the addresses
- Must be able to compute and store firstbits with additional length (i.e. 1sgtspike and 1sgtspike5 must both return 1SgTspiKe5HHkjdSeD72q9WsiJhRiaxf9)
- Must be publicly hosted to github upon completion

Bounty: $200 of BTC.

Now I realize the bounty is low for a job of this complexity, so if someone else wants to help chip in a bit more to the bounty, please do so!  It would be greatly appreciated.

Any questions?  Any volunteers who wish to code this?

7  Bitcoin / Bitcoin Technical Support / Bitcoin-QT problems on: April 15, 2014, 04:06:32 PM
I've been running a full node since 2011, updating it as needed to the latest version.  Recently, it stopped syncing beyond about 4 weeks ago.  I decided to upgrade to the latest version, 0.91, so I uninstalled the old one and deleted all the blockchain data (everything in the blocks directory).  Downloaded the 64-bit version, and launched it, only to receive this error:

It creates a blk00000.dat file and an index directory within the blocks folder during this attempt.  If I launch it again, then I get this error:

If I delete everything in the blocks folder again, I get the first error again.

What have I done wrong, and how can I fix it?
8  Bitcoin / Bitcoin Discussion / Is there a replacement for the dynamic value image? on: March 04, 2014, 10:58:47 PM
I've used this on my Minecraft website, but it's no longer relevant because it still looks up MtGox prices.  Is there an equivalent for this that pulls data from Bitstamp instead?

11  Bitcoin / Bitcoin Technical Support / How can I automatically add all Bitcoin addresses ever used to a MySQL database? on: December 12, 2013, 11:16:42 PM
How can I automatically add all Bitcoin addresses ever used to a MySQL database in realtime?

I need to move away from using's API, since the firstbits no longer appear to be working at and haven't been for some time.  I'm no expert programmer, but I know enough about PHP and MySQL querying to get the website job done.  My problem comes in getting the data from bitcoin-qt (or another source) in the first place.

I'd like to set up some sort of cron job that looks for new addresses in the latest blocks coming through, and adds said addresses to the MySQL DB after 6 confirmations.  What's the best way to accomplish this?
12  Economy / Service Discussion / WARNING: is copying my website! on: November 30, 2013, 06:55:37 AM
And for icing on the cake, they are modifying some of the data to favor their scam website!

See the feedback here:

I've never had to take down a website before - any suggestions on how to go about doing it (legally, of course)?
13  Bitcoin / Bitcoin Discussion / uBTC is better than mBTC, and here's why. on: November 25, 2013, 07:51:59 PM
We should switch to uBTC and be done with it (forever). Switch our clients, our exchanges, our store plugins, etc, to use uBTC by default.

  • It would give Bitcoin two remaining decimal places, which is what people are already familiar with, and would be much more compatible with existing financial software.
  • One uBTC is worth enough that it wouldn't be too cumbersome at this point to use. Buying something for $25 would be sending 31,255 uBTC.
  • The conversion is easy too - just remember 1 million. You multiply or divide by one million to convert between current BTC and uBTC.
  • We would only have to switch main denominations once, whereas a change to mBTC only helps us with the current price. If the value of BTC continues to go up, we'll find ourselves in the same situation of having a main denomination that is too valuable.
  • Finally, it would give enough room for BTC to grow however large and valuable it could possibly grow. Even if everyone in the world used bitcoin, uBTC + 2 decimal places would be enough to provide all the precision we would need.

Who is with me, and what are the steps we need to take to make this happen?
14  Economy / Speculation / Why a difficulty increase DOES help drive the price on: November 09, 2013, 12:30:42 AM
Many people say that the difficulty follows the price, and not the other way around.  While this is largely true, it is also true that an increase in the difficulty will help drive the price up.  Let me explain.

If I am someone who believes in Bitcoin long-term, I want to invest.  But investing doesn't have to be just buying Bitcoin directly - it can also be buying miners that produce Bitcoin.  A rational investor will look at both options:

1)  Should I buy Bitcoin directly OR
2)  Should I buy a Bitcoin miner that can turn my USD today into even more BTC down the line than what that USD would buy me today?

All the way from when BFL announced their ASIC products up through July-ish 2013, mining looked to be a potentially better option than simply buying BTC directly.  It looked as though an investor could potentially receive more BTC through mining than they could through buying BTC outright.  But now?  Now, mining is a pretty terrible investment (though it gets better with the price increase).  Investors looking to acquire BTC will simply buy BTC outright instead of buying mining machines for it.  And that will drive the price up, whereas buying miners will not.

Conversely, if the price goes up significantly without a corresponding increase in difficulty, mining will again look like an attractive option to invest in.

In this way, difficulty and price are most assuredly linked both ways, and keep each other in check.
15  Economy / Digital goods / [WTB] Windows 7 or 8 license + ISO on: September 04, 2013, 05:55:24 AM
I'd like to buy a Windows 7 or 8 unused product key, 64-bit, with the disc ISO (link to where I can download the ISO that will work with the code you give me).  Edition doesn't really matter so long as it's Home Premium or better.  Willing to consider all reasonable offers, but I do want to know your source for the product key, and will consider the price accordingly.
16  Economy / Computer hardware / [WTS] 60GH/s BFL SC Single, in-hand - 70 BTC on: August 13, 2013, 09:02:50 PM
I'd like to downsize my mining operations a bit, and am selling one 60GH/s BFL SC Single for 70 BTC.  I've had it for about 3 weeks, and it's been mining perfectly.  I've been using a computer PSU, as a BFL PSU was not included.  PSU is not included in the 70 BTC price, but I can provide one to you if necessary - just PM me to work out the details.  Included shipping will be via Priority Mail.
17  Bitcoin / Pools / How can I be alerted of worker downtime at BitMinter? on: July 26, 2013, 05:08:38 AM
I found, but they don't monitor BitMinter.  Is there ANY service that will at least send an email my way if my miners are down at BitMinter?  Those of you mining at BitMinter - what do you do?
18  Economy / Auctions / [AUCTION] Advertise on July 28 - Aug 03 on: July 24, 2013, 05:49:14 AM
This auction is for a banner ad to be ran the entire week of 2013/07/28 - 2013/08/03, any size up to 728x90 at the bottom of every forum page.  It will replace the current ad seen on the page, and will be the only advertisement on the site.

Bidding starts at 0.1 BTC, with bid increments of 0.05 BTC minimum.  Bidding begins now, and ends when this timer is depleted (24 hrs before the week of advertising is to begin).

If you are the auction winner, please PM me with your advertisement image and the page you wish to link to.  Your ad must be SFW, must not contain images or wording of a sexual nature, and must not include "swear" words.  I reserve the right to reject your advertisement and offer you a chance to revise it or refund your money in the event that I do not find a particular ad appropriate for the community.  In the event that the website is down for any reason during your advertising period, a pro-rated partial refund based on the length of downtime will be issued, or additional advertising time will be given at a future date, whichever you prefer. (also is a forum for a thriving gaming community focused around Minecraft with a large number of Bitcoin users.  A quick look at the leaderboard shows almost 800 unique individuals have received a Bitcoin payout through the Minecraft Faucet, and the rest have invariably been at least somewhat exposed to Bitcoin through the constant chatter about it among the userbase.  Cloudflare analytics show regular daily traffic is typically between 10,000 and 25,000 pageviews.

Timer removed. End time: 2013-07-27PDT
19  Economy / Service Discussion / firstbits not working on: July 23, 2013, 09:53:20 PM's firstbits lookups are not working.  1sgtspike doesn't come up.  1a comes up, but with the wrong address - it should come up with the address from block #1.
20  Economy / Services / [BOUNTY] 1 BTC for sending BTC to addresses via sendmany on: July 20, 2013, 06:00:39 AM
I have a list of around 35,000 addresses that I would like recorded in the blockchain.  PM me for the list of addresses if you are serious about completing this bounty, and include the timeline in which you expect to complete the offer.  Send 1 satoshi to each address on the list via sendmany, send me proof of doing so by sending me the transaction ID(s) you generated, and I will send you 1 BTC once all transactions have confirmed.  You must cover the fees, which I expect to total around 0.6 BTC, but could be less.  I did a test with 2,000 addresses, and the fee was 0.0345 BTC.

Quicker is better, but if you do not complete the job within the timeline you specify, then I may send the job to another willing participant, and I will not reimburse you for whatever efforts you have made up to that point.  I will, however, PM you back to let you know if the job has been sent to someone else.
