And the 1st 500bn keys (something that took the project like two months) are searched today within 30 minutes.

And we all are going to be dead when 2^256 keys are searched in this project within next couple of centuries.

Get your basics right. This project is not searching 2^256 keys.

This is fairly high praise coming from a detractor. Not many 2-century projects in human history.

There is no need for the 2^256 ...

And I'm sure compute power will get insane in the couple of years.

Ok - I try to get a GPU client at least 3x faster than the current one before you find #51.

Exceptionally, I set the pool computational front to 2^50. We will cover the ~370 tn keys after we have found #51.

You will see this on block numbers > 1073770688

The stats about predicted find time for #51 are therefore not correct anymore (because the pool is aware of missing ~370 tn keys).
So you simply have to do some calculation in your head:

If the pool says

Quote

the pool will hit the private key to 1NpnQyZ7x24ud82b7WiRNvPm6N8bqGQnaS (#51 of the puzzle transaction) in N to M days.

it currently means

Quote

the pool will hit the private key to 1NpnQyZ7x24ud82b7WiRNvPm6N8bqGQnaS (#51 of the puzzle transaction) in 0 to M-N days.

Effectively this means, I saved you 14 days or so at current speed. It also means, the find can happen anytime from now to 41 days (current speed).

Good hunting!

For this you'd need either immediate luck, or infinite speed.

To have #51 in 1 day under worst case scenario, the pool would need to have about 13.5 GKeys/s

We have officially searched about 11 tn keys in #51 search space.

Code:

[1087617328, 1087624239] <<< Unknownhostname

out of 1125 tn keys Wink

so about 1% done

Define "real"

Depends on the averaging time. The stats show a 24h average, The average in the past 1 hour will be higher.
One can estimate this from the gradient af speed growth - we're going straight up with no sign of a slowdown.
So yeah - give it a couple hours and it may show a slowdown at 480+ Mkeys.

512Mkeys = 4 million pages on directory.io per second. Insane (by todays standards).

The log files definitely belong to you, I'd say somewhere between 70 to 80% of the pool capacity is your clients.

For me it's interesting to see how the server scales. No problem there. WIthout changes, I believe the pool could handle 50 GKeys/s as is.

P2SH in BLF now

March 16, 2017, 10:26:42 PM

#596

The current .blf file contains now also P2SH addresses.

As of now, even if we find a privkey to a hash160 belonging to a P2SH address, we will not be able to do anything with it, but as there seem to be very efficient and GPU-friendly implementations how to get access - in time we will have them.

This means the blf file now contains over 14 million addresses we check against, the false positive rate is currently around 10^-23.x - that's nearly 10000 times higher than with our previous BLF files, so I consider this experimental. If it turns out there is too much noise, I will deactivate P2SH search again.

On the positive side, this means our mean search space until a collision is found is only 136.2bits (checking currently against 14582689 addresses). If it turns out all is working, I will adjust the stats and theory section accordingly.

Why not use Pushbullet?

I use it for some other stuff I do and I like it a lot.

It's official: 7 million pages on directory.io per second

My understanding is, most of this is done by one man and with CPUs.

Pool operation is seamless so far, I've seen a 13seconds network hiccup yesterday (which all clients handled well within 2 retries), and today I experienced a 500 error when calling the stats page. This too seems to have been only transient, although there may be some race condition at the bottom of this. => Pool operation purring like a cat

At the moment I'm completely dissecting the GPU client, as the segmentation faults I've been observing (read: have been driving me mad) for the past couple of days are 100% not my programming fault, but some internal error of the Nvidia OpenCL implementation. I'm trying to find a workaround and/or thorough internal analysis report to submit to Nvidia.
