Topic: Vanity Pool - vanity address generator pool (Read 147183 times)

This Vanity Pool, can vanity use GPU for hashing? is it possible that the same address appears when using this vanity pool? 

Ok ok! I thought that the vanity pool website was people selling the vanity addresses (which would make it trivial to steal funds!), but I guess they are just showing them off.

I found a good answer here:
https://bitcoin.stackexchange.com/questions/3853/can-one-safely-buy-vanity-addresses-from-a-third-party-without-risking-ones-coi

No, no!
Let me explain, this is the satoshi's wallet that holds 72 Bitcoin: 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
I have a VanitySearch and use RTX2060. If I were to try to generate exactly that address, the situation would look like this:


Here you see that hashrate of 951.41 Mkey/s takes 3.37637e+31 years FOR 50% chance to generate that address. Now, multiply 951.41 Mkey/s to whatever number of RTX 2060 GPU you want and then tell me what gives you a hope that by creating a pool, you'll be able to crack addresses. Chances are almost non-existent.

Won't vanity generators it make it easy for people to steal funds?

There's not one address holding a million Bitcoin, you'll need to brute-force 20,000 different addresses. There are currently 5,739 addresses holding exactly 50 Bitcoin, and 37,003 addresses holding 50.x Bitcoin (I can imagine many of those addresses have received some dust over the years).

1 Milliiom BTC = $32 Billion usd.

$32´000,000,000 usd.

you can buy all the Power plants you want.


when all 21 million coins are mined,
miner reward will be only the transfer fee,


nice hash calculator:
1x RTX3090 less than $8usd. /day.
https://www.nicehash.com/profitability-calculator/nvidia-rtx-3090

less than $2900usd. /year.
$29,000usd. / 10 Years. "without including electric bill increase, coin reward halved, difficulty increase, etc..."

if there is 1 Million Brute-Force miners = $1 BTC each.
vs. Ten years of work to make less money.

It's much easier to find a new block. Brute-forcing random private keys is just a waste of energy.

The problem with vanity addresses is that if you have some unique prefix, then you can be easily identified. But: if there are many people using the same prefix, if there is even some small network using only such prefixes, then it becomes harder. Reusing addresses is a bad idea, because all of them are linked. But if you want to have vanity address and you want to avoid address reuse, then you need many of such addresses, as many as the number of transactions you want to do. If you have some small network where everyone uses "bc1qtapr00t" addresses, then anyone knows that you are a part of such network, but nobody knows who you are or with who you transacted.

My plan is to create mainnet-based test network, where you deposit coins by sending them to bc1qtapr00t, then you can make test transactions inside this network, and then you withdraw your coins by moving them on mainnet. That kind of test coins will be backed 1:1 by BTC, but will have some features that are not present on mainnet. To keep coins inside of this test network, many addresses are needed to avoid address reuse. Vanity addresses are needed for advertising: in this way you can show people that there is for example some network with taproot features.

Taproot was just an example, more features will come, and then there will be no need to mine some test coins again, because you could easily move coins from "bc1qtapr00t" test chain to "bc1qtestnet", just by creating a single BTC transaction. Also, some parts of that chain could be discarded in the future, because when coins will move on BTC, then old coins from that test chain could be removed without causing any problems in full chain validation and initial test chain download.

Unless some parts or range of these private keys are already known the difficulty is still going to be too high for a million pool workers, I mean it's still 2^256 keys ftw, you might as well find everyone else's private keys along the way and demonstrate the weakness of Secp256k1.

i know it´s a crazy idea, but i can´t resist asking...

¿why Not Brute-Force the 1 Million BTC Satoshi Nakamoto address ?
they are waiting...

i know it takes a trillion years with 1x GPU,
but...
a Pool with million workers..

much more interesting / fun than mining on nicehashminer

Reward is 0 until Private Keys are found..
Reward = coins found / workers worked time.

No login, No registration.
Worker = 1My_BTC_address.worker_name
because there are many Elvis Satoshi Nakamoto Impersonators with Big Teeth Lawyers.
https://en.wikipedia.org/wiki/Elvis_impersonator

must be Tor socks, onion
private/home Proxy also nice.

IF the keys are found, and they have your IP,
there will be million More Elvis Satoshi Nakamoto´s,
and a trillion lawsuits.

IF Satoshi Nakamoto is still alive, in Guantanamo Bay or something,
https://en.wikipedia.org/wiki/Guantánamo_Bay
they will get the Keys,
just needs more motivation.

the owner of the PrvKeys just needs to move the coins to a different wallet,
and all the Brute-Force effort is lost/gone.
No risk for the Owner of the coins, IF still alive and has control of the keys.

Probably there are Secret efforts to BruteForce the keys,
why Not make more competition.?

if we dont start Now, those Decillion years will never end.

another option is the BitFinex / MtGox stolen coins.
same effort but reward is Not as Big & Juicy.

Thank you - this is really a great explanation right here.

Depends on whether you're searching for bc1 or 1 address. bc1 is not case sensitive which greatly contributes to faster times since the program does not have to consider every combination of uppercase and lowercase letter, but a normal 1 search is case sensitive.

Considering that 4-5 characters (+ case sensitive) can be found almost instantly, it's not surprising that 50% of 6-char search space is exhausted in a few days on old hardware. Newer computers have faster cores with more threads and can search the same 50% of space in several hours.

This really doesn't seem long for a 14 year old laptop and a 6 letter phrase. Isn't it supposed to be more difficult?

It's displayed as time to 50% because of the birthday paradox, where the probabilities are such that you'll find a surprisingly large amount of items by that mark.

Beyond the 50% mark, it tends to take much longer periods of time to exhaust 100%, and not necessarily the same time it took to exhaust 50%.

Always base it on that "50% in d".
In your case, It may take more more than 2 to 5 days or if you're lucky, within a few hours if you're lucky.

How long is this going to take?

Difficulty: 55527913158 [Prob 2.9%][50% in 2.4d]

"bc1qtapr00t" has a quite low difficulty of 34359738368 with VanitySearch (Official Thread link).
That'll only take a few minutes using a modern Nvidia GPU or about an hour with an Intel 4th Gen processor or equivalent.

What I'm saying is, paying $100+ isn't necessary.

Sample (please don't use):

Oclvanitygen gives me the estimate for 50% chance, so I didn't miscalculate it. But I've seen modern videocards that are 100 times faster than mine.
If you're using CPU, you could probably get much better results by switching to GPU.

Can I be curious: What's your plan with hundreds of bc1qtapr00t addresses?

You probably miscalculated something (or maybe I am extremely lucky), because when using vanitybech it took me one week per address on my CPU. One Segwit char means five bits, so seven chars means 35 bits, around 32 bits per day, so around 8 days.

It will work, the P100 has a high enough CUDA compete cap to run Vanitysearch.
