Agreed in principle, although I'm not sure 3 seconds is the right limit. I'd be alright with 5 or 10, easily.

I got 1LACheSisXMvs9w2ydkNJxRrygBfvW6nd7! I haven't gotten around to importing it yet - I'm gonna have my computer spend a week on trying to get 1Lachesis[A-Z1-9] first. However, thanks!

Sorry to bring this one back from the dead, but I've added secure remote generation to Scallion.

I'm now generating vanity .onion addresses for a small fee. See the Scallion as a Service documentation for more details. In particular, 7 and 8 character .onion addresses are free if you send me a dirty limerick featuring Tor in some way. Smiley

Contact me through the email in the documentation above or with a PM here.

5  Bitcoin / Project Development / Scallion, GPU based onion hash generator on: October 13, 2012, 04:21:58 AM
I'd like to announce Scallion, an OpenCL vanity .onion address generator. It gets around 600MH/s on a 6870 (similar on a 5770), allowing it to generate an 8-character prefix in just 15 minutes on average. It's written in C# and runs in both Linux (on Mono) and Windows.

Update (23 Nov 2013): I'm now generating vanity .onion addresses for a small fee. See the Scallion as a Service documentation for more details. In particular, 7 and 8 character .onion addresses are free if you send me a dirty limerick featuring Tor in some way. Smiley Contact me through the email given above or with a PM here.

I mentioned this in a thread over in off-topic, but that's not really the right spot for a project announcement.

Features:
1) Blindingly fast - 600MH/s vs. 2MH/s for shallot
2) Performs PKCS #1 v2.1 sanity checks via openssl's RSA_check_key function
3) FOSS - MIT licence
4) Support for 1024, 2048, or 4096 bit keys
5) Estimates time required to generate a key (on average)

Check out the Github page: http://www.github.com/lachesis/scallion
or skip straight to the binaries: https://github.com/downloads/lachesis/scallion/scallion-v0.9.zip

If you have any problems, reply to this thread or open an issue on github.

nb - are there any simple tutorials that can light me the path to gpu coding easily?
I'm not sure if there are any good top to bottom tutorials. We learned it through projects and documentation. In general, we simplify the GPU code as much as possible, both to make it fast and to avoid branches, loops, etc. Pick your favorite language, find OpenCL bindings, and run some Hello World tutorial. Then pick a project that's embarrassingly parallel (hash searches, noise generation, etc) - each result has no dependence on its neighbor. Read the documentation and pay attention to the memory model. There are a lot of hidden gotchas that can dramatically reduce your performance if you miss them.

10  Bitcoin / Mining software (miners) / Re: Flexible mining proxy on: June 22, 2011, 11:22:14 PM
I'm getting the response
Code:
{"error":"No enabled pools responded to the work request.","result":null,"id":1}
with Multipool. I just verified -- Multipool is up. In fact, when I make the exact same work request which I made to the proxy (with updated credentials) to multipool.hpc.tw, I get a response in under a second.

How can I troubleshoot this?
If you can, run a sniffer on the web server and see if it even tries to connect.  If it does, see if you can diagnose the problem from the content of the HTTP conversation.

If it does not try to connect:

  • Verify that you have pools assigned to the worker you are using.
  • Verify that the php allow_url_fopen configuration flag is set to On.
My client tried to connect twice. The proxy tried to connect a number of times and received several responses, but forwarded none on to my miner.

I wonder if there is an issue here: this server has two IPs on the same subnet. Is there a way to prioritize your proxy to choose one of them exclusively? I'm afraid it's expecting an answer on eth0 but receiving one on eth1 and not properly handling it.

An Arduino isn't needed for this; just boot to a live CD to generate your keys, put the wallet.dat on a brand new, freshly opened (and maybe encrypted) flash drive or SD-card, and generate an address. Reboot into your primary OS and send some coins to that address. Maybe reboot again to test that they were received.

Are there any ECDSA smart cards out there? It'd be pretty cool to use a smart card for Bitcoin crypto.

Hey Tim,

I just read your article. Great piece! It seems that Ars is getting the technical aspects of Bitcoin right, unlike the mainstream media.

It's still a little surreal to read about Bitcoin anywhere besides IRC and slashdot. Anyway, keep up the good work!

14  Other / Meta / [Request] Better robots.txt File / Apache Config for Google SEO on: June 14, 2011, 02:17:22 AM
I'd like to suggest some really basic SEO:

1) Modify robots.txt to hide all URLs with "?action=printpage;" in them. These "Print Page" results often come up first in the Google search results, which kinda sucks because their formatting is far worse for screen reading.
2) Configure Apache to rewrite all requests to the forum's IP (174.143.149.98) to the official forum URL. These show up in Google results and often trigger SSL errors.

Just try searching for "bitcoin dnsseed" on Google to see what I'm talking about.

Everybody will be able to enter his email IP/address on profile page, stay tuned. I'm working on it.
What if we have multiple IP addresses? I have two miners here, one at my friend's house, and one at my parents' house. Will I be able to enter all 3 IP addresses?

Don't send him your coins. You are not his insurance against software bugs. We are grateful that you help develop bitcoin and that must be enough for the guy who lost his coins.
Nobody's forcing him to do anything. I didn't ask him for coins - he offered.
17  Bitcoin / Development & Technical Discussion / Re: [PULL] Wallet Private Key Encryption on: June 11, 2011, 05:48:11 PM
I've found what appears to be a nasty bug, and has made me potentially lose 65 BTC so far:

I called "bitcoind getaccountaddress Testing" or something similar. It returned the address "1HT7xU2Ngenf7D4yocz2SAcnNLW7rK8d4E". I then sent 10BTC to this address (showing my friend how the unlock RPC command works).

A few minutes later, I called "bitcoind getaccountaddress FromMtGox" to withdraw some BTC from MtGox. It also returned "1HT7xU2Ngenf7D4yocz2SAcnNLW7rK8d4E" although I didn't notice it at the time.

In fact, no matter what account I ask for, I get that address. Even worse, I don't seem to have the private key for it. I don't see the recv part of any of the transactions that I just described in my listtransactions output.

Code:
bitcoind validateaddress 1HT7xU2Ngenf7D4yocz2SAcnNLW7rK8d4E
{
    "isvalid" : true,
    "address" : "1HT7xU2Ngenf7D4yocz2SAcnNLW7rK8d4E",
    "ismine" : false
}

If you check blockexplorer, you'll see that address has clearly received the coins. The 0.01 is from me as well. However, the 3.79 transaction is not from me. What's going on here!? Furthermore, who owns that address and how the hell did my client get it and decide to use it for all my accounts?

18  Other / Obsolete (buying) / WTB Feitian PKI smartcard from Gooze (EU residents only) on: June 06, 2011, 03:09:51 AM
Hello,

I'd like to buy a Feitian FTCOSPK01C (http://www.gooze.eu/feitian-pki-smartcard-ftcos-pk-01c) from Gooze. Unfortunately, under French law, they're not permitted to export these cards from the EU. Since I live in the USA, this means I can't buy it. So, I'll offer enough BTC to cover the cost of purchase, VAT, shipping to your residence, shipping to my residence in the US, and another few Euros worth for your time and hassle.

From what I understand, it's perfectly legal for citizens of some other EU countries (Germany) to export this crypto hardware, but IANAL. You accept all legal risk associated with this. Additionally, please ship with insurance. If I do not receive the product, I will not pay you the BTC.

It should cost around €13,80 to get the product shipped from Gooze to anywhere in the EU. I don't know how much it costs to get shipped from your country to the US. Please provide me with a quote in your reply.

I have a good rating on Gribble (lachesis on IRC as well as here). As such, and owing to the time-delayed nature of this transaction, I'd like to keep my BTC until I actually receive the smart card. We could also use clearcoin or similar if you'd like. You pay any escrow fees. I'm flexible with regards to quote time. That is, I can guarantee the number of Bitcoins that you'll receive when I get the smart-card beforehand if you'd like, or we can wait until I actually get it to determine this amount. Obviously if you expect Bitcoin to go up in value, you want a quote now, but if you expect it to drop, you want one at the end.

Thanks,
Lachesis
