A couple of question about https://vanitypool.appspot.com/

1) How can I know if I have to use compressed or uncompressed keys for the search? For example, in this case:

https://vanitypool.appspot.com/availableWork   -->  "11111111"
public key: 04C13D9CF2B0E382A4AF29C5E2B97F85C6DD9445F7DCE82CD7207E6FC4716511981B0012C10B39EF1 52257A8407A2965F92F075379D311D5786D9421795B82D01C

can I use only compressed keys?

I found this public key:

Code:
a15f585a9d39a8a091962d11af1e96320fc3543b5201a8c9b12eedf695bad359 3b6621eddf4207bd186c8293c6b497555594b32d2eb9c09ae8f81791a0dfde48

if I add it with the public key
Code:
C13D9CF2B0E382A4AF29C5E2B97F85C6DD9445F7DCE82CD7207E6FC471651198 1B0012C10B39EF152257A8407A2965F92F075379D311D5786D9421795B82D01C

I get this public key

Code:
83f0e53639fbcead931a0d19eb3f3f6684dc75fac68a8c5dbc21cdb8b4ecfb19 d933c437e192b2b6dd27a6b9d09e6470ca220ed27d4bcb05251b1d0e47adad90

in compressed format

Code:
0283f0e53639fbcead931a0d19eb3f3f6684dc75fac68a8c5dbc21cdb8b4ecfb19

that gives this address (only 7 '1'):

Code:
11111113ix5Nw6kgetPaMBCWBdp5TTfX

My question is: if I found a match with the pattern "11111111", would it be valid? Or do I have to use only uncompressed keys?

I don't want to waste time with a fruitless quest.

Nah, you do not have to worry about your BTC getting halved or that it will somehow be reduced to create these other coins.

I think there are a lot of people who are getting this wrong and are totally confused with all the FUD that are being spread.

Your original bitcoins are safe, just keep the private key secret and wait for the fork. After the fork, you will have coins from

the new fork too... You can sell or keep those coins, if you have sole control over your private key. Some people store their

bitcoins in services where these services have control over your private key and they can decide what they want to do with

those forked coins.

I have a question: using vanitygen it outputs I generate 20Mkeys/s

but when i start:

vanitygen -k -q -i -o out.txt 1

it saves only few addresses.

I don t understand the delta between the power displayed (20Mkeys/s) and the number of address found.

Someone can explain me please?

Regards

Are you sure you get 20 Mkeys/s out of vanitygen? The speed sounds like you're using oclvanitygen.

I ran both for about 5 seconds:
Code:
./vanitygen -k -q -i -o out.txt 1
[168.47 Kkey/s][total 669228][Found 2971]

./oclvanitygen -k -q -i -o out.txt 1
[4.84 Mkey/s][total 31457280][Found 5]
I've been struggling to understand this before, but I don't understand the details enough to know exactly why this is.
From what I understand: oclvanitygen can only output about 1 key per second, it takes time to restart the process in the GPU. Vanitygen searches short prefixes much faster, but loses speed too when it has to output all addresses.
As for why 168 kkeys/s for approximately 5 seconds only outputs 2971 addresses: that's only 1 in approximately 280. I'm not sure why that is.

Vanitygen is a address search application, it runs the calculations in address-batches to optimize the heavy EC_POINT calculations.
The search functionality will disregard remaining calculations in the batch when it finds a match.
If only a "1" is specified in the search, each calculation yields a valid result, so the first in the batch is a match, the rest is
disregarded. If you want to use vanitygen as an address generator, you need to change the code to search in smaller batches.

I don't know the specifics of oclvanitygen, but most software that runs on a GPU runs even larger (parallel) batches.
If the same match and throw away routine is used, oclvanitygen will be less productive then vanitygen on small searches.

Do you want only to generate many addresses? What speed do you need?

Actually I m near 1500key/s using a custom application but I need at least 100000 keys/second for an educational project with students.

Vanitygen appears great soft but it outputs very low number of keys :-(

Any ideas are welcome

If you need only addresses, without private keys:

Code:

You need only addresses or private keys too?
You need addresses in base58 or only as hexdecimal string?

I have a my own generator (for Linux) that produces private key + address but not in base58 format.

I have another program in Python too that produces private key + address, I should search it. I don't remember performance, but surely much more than 1500keys/s. Are you interested?

it's been awhile since last time I'm following this thread
as I look into the generated address/key pair, they are seem all uncompressed
with the increasing tx fee, the need of compressed address becomes common
is there a way to (turn on) search pattern on both uncompressed and compressed addresses
sound like a waste if only checking pattern on uncompressed address generated,
because there is also corresponding compressed address that can be checked at the same time

It's important to note that searching for short addresses (<34 standard character address length) by utilising "1"*n patterns has a greater difficulty than other patterns of the same length.

I have found several hundred 31 length addresses and a few (2 or 3) 30 character addresses running my 7950 at work over a many-month long period of time.

Thanks for the trust.   Cheesy

Anyway my program generates only "consecutive" keys. You provide:

1) the private key to start from
2) how many keys you want to compute

and it generates the corresponding addresses (hash of public keys, not base58 encoded). This is the output if you start from key = 1:

Code:

It is only up to the user to choose which keys to generate, not up to the program.

Besides I don't think that jhdscript needs to store a so huge amount of addresses to send some bitcoin there. Maybe it is only a statistical project.


@jhdscript

I made 2 tests (writing speed, Xeon CPU E3-1505 3 GHz + SSD, Ubuntu Mate 17.04)

1) supervanitygen:  about 220K keys / minute (8 threads,  that confirms that vanitygen-like program are not suited to your case)

2) my own generator: 75M keys / minute (-> 6,5GB file / minute) per 1 core. I got about 175 Mkeys / minute with 4 cores.

Unfortunately if I try to compile it for Windows the results I get are not correct anymore.  When I will have more time I will give it a look. For now I can't help you  (unless you decide to use Linux).
Honestly I can't figure out why you need to fill an hard disk so fast. It takes about 20 hours to fill 4TB.

...The more times you try, the more likely it becomes to roll a 6.
Dice have no memory. The chance to roll a 6 is the same at every throw. So it is NOT more likely to throw a 6 the more times you try.

Guys, I've asked about probability and time previously: 1, 2 and got the answer that "Dice have no memory."

Okay, but I still could not understand what does it mean on practice. And to illustrate my frustration here is the animated image (actually it is html+css).

So, I could search forever for my 1 exact 9-prefixed address?

you should read on math subject of probability and chance
in short, probability is theoritical calculation on possible outcomes while chance is based on luck factor
in this vanitygen case, your luck depends on random seed producing targeted pattern
thus the chance is the same everytime because you starting with random seed every time

If you're running searches for months, you may want to make a longer list of words to search for. By making a list with prefixes you may find more cool addresses in the same amount of time.
and I agree with what he said, add a few more patterns to make it worthwhile
so with multiple pattern search on single run you can get your other desired patterns at once
for example: 1Thirdspace 1Th3rdspace 1Thirdsp4ce 1Th3rdsp4ce 13rdspace
if you just do single pattern, you might missed the chance hitting the other patterns
I wish I have the power to do that kind of pattern
but I was a bit lucky with 1Third address (on profile) using only cpu power
I got it in around 10-12 hour while it says 50% in 1.1d at the beginning

btw can someone response to my question a few post earlier
anyhow to modify the code to also work/search on compressed addresses
